-## Project Overview
-
-LeRobot is a PyTorch-based library for real-world robotics, providing datasets, pretrained policies, and tools for training, evaluation, data collection, and robot control. It integrates with Hugging Face Hub for model/dataset sharing.
-
-## Tech Stack
-
-Python 3.12+ · PyTorch · Hugging Face (datasets, Hub, accelerate) · draccus (config/CLI) · Gymnasium (envs) · uv (package management)
-
-## Development Setup
-
-```bash
-uv sync --locked                            # Base dependencies
-uv sync --locked --extra test --extra dev   # Test + dev tools
-uv sync --locked --extra all                # Everything
-git lfs install && git lfs pull             # Test artifacts
-```
-
-## Key Commands
-
-```bash
-uv run pytest tests -svv --maxfail=10                 # All tests
-DEVICE=cuda make test-end-to-end                      # All E2E tests
-pre-commit run --all-files                           # Lint + format (ruff, typos, bandit, etc.)
-```
-
-## Architecture (`src/lerobot/`)
-
-- **`scripts/`** — CLI entry points (`lerobot-train`, `lerobot-eval`, `lerobot-record`, etc.), mapped in `pyproject.toml [project.scripts]`.
-- **`configs/`** — Dataclass configs parsed by draccus. `train.py` has `TrainPipelineConfig` (top-level). `policies.py` has `PreTrainedConfig` base. Polymorphism via `draccus.ChoiceRegistry` with `@register_subclass("name")` decorators.
-- **`policies/`** — Each policy in its own subdir. All inherit `PreTrainedPolicy` (`nn.Module` + `HubMixin`) from `pretrained.py`. Factory with lazy imports in `factory.py`.
-- **`processor/`** — Data transformation pipeline. `ProcessorStep` base with registry. `DataProcessorPipeline` / `PolicyProcessorPipeline` chain steps.
-- **`datasets/`** — `LeRobotDataset` (episode-aware sampling + video decoding) and `LeRobotDatasetMetadata`.
-- **`envs/`** — `EnvConfig` base in `configs.py`, factory in `factory.py`. Each env subclass defines `gym_kwargs` and `create_envs()`.
-- **`robots/`, `motors/`, `cameras/`, `teleoperators/`** — Hardware abstraction layers.
-- **`types.py`** and **`configs/types.py`** — Core type aliases and feature type definitions.
-
-## Repository Structure (outside `src/`)
-
-- **`tests/`** — Pytest suite organized by module. Fixtures in `tests/fixtures/`, mocks in `tests/mocks/`. Hardware tests use skip decorators from `tests/utils.py`. E2E tests via `Makefile` write to `tests/outputs/`.
-- **`.github/workflows/`** — CI: `quality.yml` (pre-commit), `fast_tests.yml` (base deps, every PR), `full_tests.yml` (all extras + E2E + GPU, post-approval), `latest_deps_tests.yml` (daily lockfile upgrade), `security.yml` (TruffleHog), `release.yml` (PyPI publish on tags).
-- **`docs/source/`** — HF documentation (`.mdx` files). Per-policy READMEs, hardware guides, tutorials. Built separately via `docs-requirements.txt` and CI workflows.
-- **`examples/`** — End-user tutorials and scripts organized by use case (dataset creation, training, hardware setup).
-- **`docker/`** — Dockerfiles for user (`Dockerfile.user`) and CI (`Dockerfile.internal`).
-- **`benchmarks/`** — Performance benchmarking scripts.
-- **Root files**: `pyproject.toml` (single source of truth for deps, build, tool config), `Makefile` (E2E test targets), `uv.lock`, `CONTRIBUTING.md` & `README.md` (general information).
-
-## Notes
-
-- **Mypy is gradual**: strict only for `lerobot.envs`, `lerobot.configs`, `lerobot.optim`, `lerobot.model`, `lerobot.cameras`, `lerobot.motors`, `lerobot.transport`. Add type annotations when modifying these modules.
-- **Optional dependencies**: many policies, envs, and robots are behind extras (e.g., `lerobot[aloha]`). New imports for optional packages must be guarded or lazy. See `pyproject.toml [project.optional-dependencies]`.
-- **Video decoding**: datasets can store observations as video files. `LeRobotDataset` handles frame extraction, but tests need ffmpeg installed.
-- **Prioritize use of `uv run`** to execute Python commands (not raw `python` or `pip`).

-# Docker
-
-This directory contains Dockerfiles for running LeRobot in containerized environments. Both images are **built nightly from `main`** and published to Docker Hub with the full environment pre-baked — no dependency setup required.
-
-## Pre-built Images
-
-```bash
-# CPU-only image (based on Dockerfile.user)
-docker pull huggingface/lerobot-cpu:latest
-
-# GPU image with CUDA support (based on Dockerfile.internal)
-docker pull huggingface/lerobot-gpu:latest
-```
-
-## Quick Start
-
-The fastest way to start training is to pull the GPU image and run `lerobot-train` directly. This is the same environment used for all of our CI, so it is a well-tested, batteries-included setup.
-
-```bash
-docker run -it --rm --gpus all --shm-size 16gb huggingface/lerobot-gpu:latest
-
-# inside the container:
-lerobot-train --policy.type=act --dataset.repo_id=lerobot/aloha_sim_transfer_cube_human
-```
-
-## Dockerfiles
-
-### `Dockerfile.user` (CPU)
-
-A lightweight image based on `python:3.12-slim`. Includes all Python dependencies and system libraries but does not include CUDA — there is no GPU support. Useful for exploring the codebase, running scripts, or working with robots, but not practical for training.
-
-### `Dockerfile.internal` (GPU)
-
-A CUDA-enabled image based on `nvidia/cuda`. This is the image for training — mostly used for internal interactions with the GPU cluster.
-
-## Usage
-
-### Running a pre-built image
-
-```bash
-# CPU
-docker run -it --rm huggingface/lerobot-cpu:latest
-
-# GPU
-docker run -it --rm --gpus all --shm-size 16gb huggingface/lerobot-gpu:latest
-```
-
-### Building locally
-
-From the repo root:
-
-```bash
-# CPU
-docker build -f docker/Dockerfile.user -t lerobot-user .
-docker run -it --rm lerobot-user
-
-# GPU
-docker build -f docker/Dockerfile.internal -t lerobot-internal .
-docker run -it --rm --gpus all --shm-size 16gb lerobot-internal
-```
-
-### Multi-GPU training
-
-To select specific GPUs, set `CUDA_VISIBLE_DEVICES` when launching the container:
-
-```bash
-# Use 4 GPUs
-docker run -it --rm --gpus all --shm-size 16gb \
-  -e CUDA_VISIBLE_DEVICES=0,1,2,3 \
-  huggingface/lerobot-gpu:latest
-```
-
-### USB device access (e.g. robots, cameras)
-
-```bash
-docker run -it --device=/dev/ -v /dev/:/dev/ --rm huggingface/lerobot-cpu:latest

-# Action Representations
-
-This guide explains the different ways robot actions can be represented in LeRobot, how they relate to each other, and when to use each one.
-
-## Joint Space vs End-Effector Space
-
-Before discussing action representations, it helps to understand the two coordinate spaces actions can live in.
-
-### Joint Space
-
-Joint-space actions directly specify target positions for each motor. For a 6-DOF arm with a gripper, a joint-space action might look like:
-
-```
-action = [shoulder_pan: 45.0, shoulder_lift: -20.0, elbow: -30.0, wrist_pitch: 10.0, wrist_roll: 0.0, wrist_yaw: 5.0, gripper: 0.8]
-```
-
-Joint space is the default in LeRobot. It is simple, requires no kinematics model, and maps directly to motor commands. Most beginner setups (SO-100, Koch) use joint-space actions.
-
-### End-Effector (EE) Space
-
-End-effector-space actions specify the desired position and orientation of the robot's tool tip (gripper) in Cartesian coordinates:
-
-```
-action = [x: 0.25, y: -0.10, z: 0.15, wx: 0.0, wy: 0.0, wz: 0.1, gripper: 0.8]
-```
-
-EE space is more intuitive for tasks like pick-and-place because it directly describes where the gripper should go, but it requires a kinematics model (URDF) to convert between EE poses and joint angles.
-
-### Converting Between Spaces
-
-LeRobot provides processor steps for converting between joint and EE spaces using forward and inverse kinematics. These are built on top of `RobotKinematics`, which loads a URDF model of your robot.
-
-```python
-from lerobot.model.kinematics import RobotKinematics
-from lerobot.robots.so_follower.robot_kinematic_processor import (
-    ForwardKinematicsJointsToEE,
-    InverseKinematicsEEToJoints,
-)
-
-kinematics = RobotKinematics(
-    urdf_path="./SO101/so101_new_calib.urdf",
-    target_frame_name="gripper_frame_link",
-    joint_names=["shoulder", "elbow", "wrist_pitch", "wrist_roll", "wrist_yaw"],
-)
-
-# Joints → EE (for observations: "where is my gripper?")
-fk_step = ForwardKinematicsJointsToEE(kinematics=kinematics, motor_names=[...])
-
-# EE → Joints (for actions: "move my gripper here")
-ik_step = InverseKinematicsEEToJoints(kinematics=kinematics, motor_names=[...])
-```
-
-See [`examples/so100_to_so100_EE/`](https://github.com/huggingface/lerobot/tree/main/examples/so100_to_so100_EE) for a complete working example of recording, replaying, and evaluating with EE-space actions on an SO-100 arm.
-
-## Absolute, Relative, and Delta Actions
-
-Regardless of whether you work in joint space or EE space, the action values can be expressed in three different ways. The terminology follows [UMI (Chi et al., 2024)](https://arxiv.org/abs/2402.10329).
-
-### Absolute Actions (LeRobot default)
-
-Each action specifies the target position directly.
-
-**Example** (joint space, chunk of 4):
-
-```
-current_state = [45.0, -30.0, 10.0]
-
-action_chunk = [
-    [46.0, -29.0, 11.0],   # go to 46, -29, 11
-    [47.5, -27.0, 12.0],   # go to 47.5, -27, 12
-    [49.0, -25.0, 13.5],   # go to 49, -25, 13.5
-    [50.0, -24.0, 15.0],   # go to 50, -24, 15
-]
-```
-
-Each value is a target position in the robot's coordinate frame. Simple and direct, but requires a consistent global coordinate frame. This is the default in LeRobot.
-
-### Relative Actions (used by OpenPI / pi0)
-
-Each action in the chunk is an offset from the **current state at the moment of prediction**. All actions in the chunk share the same reference point:
-
-```
-current_state = [45.0, -30.0, 10.0]
-
-relative_chunk = [
-    [1.0,  1.0, 1.0],   # +1 from current → target 46, -29, 11
-    [2.5,  3.0, 2.0],   # +2.5 from current → target 47.5, -27, 12
-    [4.0,  5.0, 3.5],   # +4 from current → target 49, -25, 13.5
-    [5.0,  6.0, 5.0],   # +5 from current → target 50, -24, 15
-]
-```
-
-The conversion is straightforward: `relative = absolute - current_state`. To recover absolute: `absolute = relative + current_state`.
-
-**Why use relative actions?** The model learns to predict offsets centered around zero, which is easier to normalize and leads to more stable training. Because every chunk references the same current state, there is no error accumulation across chunks.
-
-### Delta Actions (sequential differences)
-
-Each action is an offset from the **previous action** (or from the current state for the first step):
-
-```
-current_state = [45.0, -30.0, 10.0]
-
-delta_chunk = [
-    [1.0,  1.0, 1.0],   # current → 46, -29, 11
-    [1.5,  2.0, 1.0],   # previous action → 47.5, -27, 12
-    [1.5,  2.0, 1.5],   # previous action → 49, -25, 13.5
-    [1.0,  1.0, 1.5],   # previous action → 50, -24, 15
-]
-```
-
-Here each step is relative to the one before it. To recover absolute positions you must sum all previous deltas, which means errors accumulate over time. UMI explicitly argues against this representation for this reason.
-
-### Visual Comparison
-
-The figure below (based on a figure from [UMI, Chi et al., 2024](https://arxiv.org/abs/2402.10329)) illustrates the key difference. With **relative trajectory**, every action in the chunk points back to the same origin (current state), so a new inference step cleanly resets the reference. With **delta**, each action depends on the previous one, so errors accumulate. **Absolute** actions require a consistent global coordinate frame.

-
-## Using Relative Actions in LeRobot
-
-LeRobot provides `RelativeActionsProcessorStep` to convert between absolute and relative actions inside the processor pipeline. This is how pi0, pi0.5, and pi0_fast support relative actions.
-
-> **Note:** All pi models (pi0, pi0.5, pi0*fast) apply relative conversion \_before* normalization (`relative → normalize`), so the normalizer always sees delta (relative) values. This means **relative action stats are required** for all of them when training with `use_relative_actions=true`. In pi0_fast the `RelativeActionsProcessorStep` only modifies the action — the state observation is unchanged — so `NormalizerProcessorStep` still runs before the state tokenizer and the tokenizer continues to receive normalized state as expected.
-
-### How it works
-
-During **training** (preprocessing), actions are converted from absolute to relative before the model sees them:
-
-```
-raw absolute action → RelativeActionsProcessorStep → normalize → model
-```
-
-During **inference** (postprocessing), model predictions are converted back to absolute before being sent to the robot:
-
-```
-model output → unnormalize → AbsoluteActionsProcessorStep → robot
-```
-
-The `AbsoluteActionsProcessorStep` reads the cached current state from its paired `RelativeActionsProcessorStep`, so the two must be wired together (handled automatically by the policy factory).
-
-### Enabling relative actions for the pi family (pi0, pi0.5, pi0_fast)
-
-**Step 1**: Precompute relative action statistics for your dataset:
-
-```bash
-lerobot-edit-dataset \
-    --repo_id your_dataset \
-    --operation.type recompute_stats \
-    --operation.relative_action true \
-    --operation.chunk_size 50 \
-    --operation.relative_exclude_joints "['gripper']"
-```
-
-**Step 2**: Train with relative actions enabled:
-
-```bash
-lerobot-train \
-    --dataset.repo_id=your_dataset \
-    --policy.type=pi0 \
-    --policy.use_relative_actions=true \
-    --policy.relative_exclude_joints='["gripper"]'
-```
-
-The `relative_exclude_joints` parameter specifies joints that should remain in absolute space. For example, gripper commands are typically binary (open/close) and don't benefit from relative encoding.
-
-### Combining relative actions with RTC
-
-[RTC](https://arxiv.org/abs/2506.07339) runs policy inference at high frequency and sends actions to the robot as they are predicted rather than waiting for a full chunk. Relative actions and RTC are fully compatible: because every chunk in relative mode references the **same** current state (captured at the start of inference), each predicted action in the chunk remains a valid offset even if the robot has already moved. No special handling is needed — `RelativeActionsProcessorStep` caches the state once per inference call and `AbsoluteActionsProcessorStep` applies it to every action in the streamed output.
-
-### Combining relative actions with EE space
-
-Relative actions work in both joint space and EE space. For example, if your dataset stores EE actions, relative encoding converts them to offsets from the current EE pose:
-
-```
-current_ee_state = [x: 0.25, y: -0.10, z: 0.15, gripper: 0.8]
-
-absolute_ee_chunk = [
-    [0.26, -0.09, 0.16, 0.8],
-    [0.28, -0.07, 0.18, 0.8],
-]
-
-relative_ee_chunk = [
-    [0.01,  0.01, 0.01, 0.0],   # offset from current EE pose
-    [0.03,  0.03, 0.03, 0.0],   # offset from current EE pose
-]
-```
-

-
-Here is how the different processors compose. Each arrow is a processor step, and they can be chained in a `RobotProcessorPipeline` or `PolicyProcessorPipeline`:

-# Adding a New Benchmark
-
-This guide walks you through adding a new simulation benchmark to LeRobot. Follow the steps in order and use the existing benchmarks as templates.
-
-A benchmark in LeRobot is a set of [Gymnasium](https://gymnasium.farama.org/) environments that wrap a third-party simulator (like LIBERO or Meta-World) behind a standard `gym.Env` interface. The `lerobot-eval` CLI then runs evaluation uniformly across all benchmarks.
-
-## Existing benchmarks at a glance
-
-Before diving in, here is what is already integrated:
-
-| Benchmark      | Env file            | Config class       | Tasks               | Action dim   | Processor                    |
-| -------------- | ------------------- | ------------------ | ------------------- | ------------ | ---------------------------- |
-| LIBERO         | `envs/libero.py`    | `LiberoEnv`        | 130 across 5 suites | 7            | `LiberoProcessorStep`        |
-| Meta-World     | `envs/metaworld.py` | `MetaworldEnv`     | 50 (MT50)           | 4            | None                         |
-| IsaacLab Arena | Hub-hosted          | `IsaaclabArenaEnv` | Configurable        | Configurable | `IsaaclabArenaProcessorStep` |
-
-Use `src/lerobot/envs/libero.py` and `src/lerobot/envs/metaworld.py` as reference implementations.
-
-## How it all fits together
-
-### Data flow
-
-During evaluation, data moves through four stages:
-
-```
-1. gym.Env  ──→  raw observations (numpy dicts)
-
-2. Preprocessing  ──→  standard LeRobot keys + task description
-   (preprocess_observation in envs/utils.py, env.call("task_description"))
-
-3. Processors  ──→  env-specific then policy-specific transforms
-   (env_preprocessor, policy_preprocessor)
-
-4. Policy  ──→  select_action()  ──→  action tensor
-   then reverse: policy_postprocessor → env_postprocessor → numpy action → env.step()
-```
-
-Most benchmarks only need to care about stage 1 (producing observations in the right format) and optionally stage 3 (if env-specific transforms are needed).
-
-### Environment structure
-
-`make_env()` returns a nested dict of vectorized environments:
-
-```python
-dict[str, dict[int, gym.vector.VectorEnv]]
-#    ^suite       ^task_id
-```
-
-A single-task env (e.g. PushT) looks like `{"pusht": {0: vec_env}}`.
-A multi-task benchmark (e.g. LIBERO) looks like `{"libero_spatial": {0: vec0, 1: vec1, ...}, ...}`.
-
-### How evaluation runs
-
-All benchmarks are evaluated the same way by `lerobot-eval`:
-
-1. `make_env()` builds the nested `{suite: {task_id: VectorEnv}}` dict.
-2. `eval_policy_all()` iterates over every suite and task.
-3. For each task, it runs `n_episodes` rollouts via `rollout()`.
-4. Results are aggregated hierarchically: episode, task, suite, overall.
-5. Metrics include `pc_success` (success rate), `avg_sum_reward`, and `avg_max_reward`.
-
-The critical piece: your env must return `info["is_success"]` on every `step()` call. This is how the eval loop knows whether a task was completed.
-
-## What your environment must provide
-
-LeRobot does not enforce a strict observation schema. Instead it relies on a set of conventions that all benchmarks follow.
-
-### Env attributes
-
-Your `gym.Env` must set these attributes:
-
-| Attribute            | Type  | Why                                                  |
-| -------------------- | ----- | ---------------------------------------------------- |
-| `_max_episode_steps` | `int` | `rollout()` uses this to cap episode length          |
-| `task_description`   | `str` | Passed to VLA policies as a language instruction     |
-| `task`               | `str` | Fallback identifier if `task_description` is not set |
-
-### Success reporting
-
-Your `step()` and `reset()` must include `"is_success"` in the `info` dict:
-
-```python
-info = {"is_success": True}   # or False
-return observation, reward, terminated, truncated, info
-```
-
-### Observations
-
-The simplest approach is to map your simulator's outputs to the standard keys that `preprocess_observation()` already understands. Do this inside your `gym.Env` (e.g. in a `_format_raw_obs()` helper):
-
-| Your env should output    | LeRobot maps it to         | What it is                            |
-| ------------------------- | -------------------------- | ------------------------------------- |
-| `"pixels"` (single array) | `observation.image`        | Single camera image, HWC uint8        |
-| `"pixels"` (dict)         | `observation.images.<cam>` | Multiple cameras, each HWC uint8      |
-| `"agent_pos"`             | `observation.state`        | Proprioceptive state vector           |
-| `"environment_state"`     | `observation.env_state`    | Full environment state (e.g. PushT)   |
-| `"robot_state"`           | `observation.robot_state`  | Nested robot state dict (e.g. LIBERO) |
-
-If your simulator uses different key names, you have two options:
-
-1. **Recommended:** Rename them to the standard keys inside your `gym.Env` wrapper.
-2. **Alternative:** Write an env processor to transform observations after `preprocess_observation()` runs (see step 4 below).
-
-### Actions
-
-Actions are continuous numpy arrays in a `gym.spaces.Box`. The dimensionality depends on your benchmark (7 for LIBERO, 4 for Meta-World, etc.). Policies adapt to different action dimensions through their `input_features` / `output_features` config.
-
-### Feature declaration
-
-Each `EnvConfig` subclass declares two dicts that tell the policy what to expect:
-
-- `features` — maps feature names to `PolicyFeature(type, shape)` (e.g. action dim, image shape).
-- `features_map` — maps raw observation keys to LeRobot convention keys (e.g. `"agent_pos"` to `"observation.state"`).
-
-## Step by step
-
-<Tip>
-  At minimum, you need two files: a **gym.Env wrapper** and an **EnvConfig
-  subclass** with a `create_envs()` override. Everything else is optional or
-  documentation. No changes to `factory.py` are needed.
-</Tip>

-
-### 1. The gym.Env wrapper (`src/lerobot/envs/<benchmark>.py`)
-
-Create a `gym.Env` subclass that wraps the third-party simulator:
-
-```python
-class MyBenchmarkEnv(gym.Env):
-    metadata = {"render_modes": ["rgb_array"], "render_fps": <fps>}
-
-    def __init__(self, task_suite, task_id, ...):
-        super().__init__()
-        self.task = <task_name_string>
-        self.task_description = <natural_language_instruction>
-        self._max_episode_steps = <max_steps>
-        self.observation_space = spaces.Dict({...})
-        self.action_space = spaces.Box(low=..., high=..., shape=(...,), dtype=np.float32)
-
-    def reset(self, seed=None, **kwargs):
-        ...  # return (observation, info) — info must contain {"is_success": False}
-
-    def step(self, action: np.ndarray):
-        ...  # return (obs, reward, terminated, truncated, info) — info must contain {"is_success": <bool>}
-
-    def render(self):
-        ...  # return RGB image as numpy array
-
-    def close(self):
-        ...
-```
-
-**GPU-based simulators (e.g. MuJoCo with EGL rendering):** If your simulator allocates GPU/EGL contexts during `__init__`, defer that allocation to a `_ensure_env()` helper called on first `reset()`/`step()`. This avoids inheriting stale GPU handles when `AsyncVectorEnv` spawns worker processes. See `LiberoEnv._ensure_env()` for the pattern.
-
-Also provide a factory function that returns the nested dict structure:
-
-```python
-def create_mybenchmark_envs(
-    task: str,
-    n_envs: int,
-    gym_kwargs: dict | None = None,
-    env_cls: type | None = None,
-) -> dict[str, dict[int, Any]]:
-    """Create {suite_name: {task_id: VectorEnv}} for MyBenchmark."""
-    ...
-```
-
-See `create_libero_envs()` (multi-suite, multi-task) and `create_metaworld_envs()` (difficulty-grouped tasks) for reference.
-
-### 2. The config (`src/lerobot/envs/configs.py`)
-
-Register a config dataclass so users can select your benchmark with `--env.type=<name>`. Each config owns its environment creation and processor logic via two methods:
-
-- **`create_envs(n_envs, use_async_envs)`** — Returns `{suite: {task_id: VectorEnv}}`. The base class default uses `gym.make()` for single-task envs. Multi-task benchmarks override this.
-- **`get_env_processors()`** — Returns `(preprocessor, postprocessor)`. The base class default returns identity (no-op) pipelines. Override if your benchmark needs observation/action transforms.
-
-```python
-@EnvConfig.register_subclass("<benchmark_name>")
-@dataclass
-class MyBenchmarkEnvConfig(EnvConfig):
-    task: str = "<default_task>"
-    fps: int = <fps>
-    obs_type: str = "pixels_agent_pos"
-
-    features: dict[str, PolicyFeature] = field(default_factory=lambda: {
-        ACTION: PolicyFeature(type=FeatureType.ACTION, shape=(<action_dim>,)),
-    })
-    features_map: dict[str, str] = field(default_factory=lambda: {
-        ACTION: ACTION,
-        "agent_pos": OBS_STATE,
-        "pixels": OBS_IMAGE,
-    })
-
-    def __post_init__(self):
-        ...  # populate features based on obs_type
-
-    @property
-    def gym_kwargs(self) -> dict:
-        return {"obs_type": self.obs_type, "render_mode": self.render_mode}
-
-    def create_envs(self, n_envs: int, use_async_envs: bool = True):
-        """Override for multi-task benchmarks or custom env creation."""
-        from lerobot.envs.<benchmark> import create_<benchmark>_envs
-        return create_<benchmark>_envs(task=self.task, n_envs=n_envs, ...)
-
-    def get_env_processors(self):
-        """Override if your benchmark needs observation/action transforms."""
-        from lerobot.processor import PolicyProcessorPipeline
-        from lerobot.processor.env_processor import MyBenchmarkProcessorStep
-        return (
-            PolicyProcessorPipeline(steps=[MyBenchmarkProcessorStep()]),
-            PolicyProcessorPipeline(steps=[]),
-        )
-```
-
-Key points:
-
-- The `register_subclass` name is what users pass on the CLI (`--env.type=<name>`).
-- `features` tells the policy what the environment produces.
-- `features_map` maps raw observation keys to LeRobot convention keys.
-- **No changes to `factory.py` needed** — the factory delegates to `cfg.create_envs()` and `cfg.get_env_processors()` automatically.
-
-### 3. Env processor (optional — `src/lerobot/processor/env_processor.py`)
-
-Only needed if your benchmark requires observation transforms beyond what `preprocess_observation()` handles (e.g. image flipping, coordinate conversion). Define the processor step here and return it from `get_env_processors()` in your config (see step 2):
-
-```python
-@dataclass
-@ProcessorStepRegistry.register(name="<benchmark>_processor")
-class MyBenchmarkProcessorStep(ObservationProcessorStep):
-    def _process_observation(self, observation):
-        processed = observation.copy()
-        # your transforms here
-        return processed
-
-    def transform_features(self, features):
-        return features  # update if shapes change
-
-    def observation(self, observation):
-        return self._process_observation(observation)
-```
-
-See `LiberoProcessorStep` for a full example (image rotation, quaternion-to-axis-angle conversion).
-
-### 4. Dependencies (`pyproject.toml`)
-
-Add a new optional-dependency group:
-
-```toml
-mybenchmark = ["my-benchmark-pkg==1.2.3", "lerobot[scipy-dep]"]
-```
-
-Pinning rules:
-
-- **Always pin** benchmark packages to exact versions for reproducibility (e.g. `metaworld==3.0.0`).
-- **Add platform markers** when needed (e.g. `; sys_platform == 'linux'`).
-- **Pin fragile transitive deps** if known (e.g. `gymnasium==1.1.0` for Meta-World).
-- **Document constraints** in your benchmark doc page.
-
-Users install with:
-
-```bash
-pip install -e ".[mybenchmark]"
-```
-
-### 5. Documentation (`docs/source/<benchmark>.mdx`)
-
-Write a user-facing page following the template in the next section. See `docs/source/libero.mdx` and `docs/source/metaworld.mdx` for full examples.
-
-### 6. Table of contents (`docs/source/_toctree.yml`)
-
-Add your benchmark to the "Benchmarks" section:
-
-```yaml
-- sections:
-    - local: libero
-      title: LIBERO
-    - local: metaworld
-      title: Meta-World
-    - local: envhub_isaaclab_arena
-      title: NVIDIA IsaacLab Arena Environments
-    - local: <your_benchmark>
-      title: <Your Benchmark Name>
-  title: "Benchmarks"
-```
-
-## Verifying your integration
-
-After completing the steps above, confirm that everything works:
-
-1. **Install** — `pip install -e ".[mybenchmark]"` and verify the dependency group installs cleanly.
-2. **Smoke test env creation** — call `make_env()` with your config in Python, check that the returned dict has the expected `{suite: {task_id: VectorEnv}}` shape, and that `reset()` returns observations with the right keys.
-3. **Run a full eval** — `lerobot-eval --env.type=<name> --env.task=<task> --eval.n_episodes=1 --policy.path=<any_compatible_policy>` to exercise the full pipeline end-to-end. (`batch_size` defaults to auto-tuning based on CPU cores; pass `--eval.batch_size=1` to force a single environment.)
-4. **Check success detection** — verify that `info["is_success"]` flips to `True` when the task is actually completed. This is what the eval loop uses to compute success rates.
-
-## Writing a benchmark doc page
-
-Each benchmark `.mdx` page should include:
-
-- **Title and description** — 1-2 paragraphs on what the benchmark tests and why it matters.
-- **Links** — paper, GitHub repo, project website (if available).
-- **Overview image or GIF.**
-- **Available tasks** — table of task suites with counts and brief descriptions.
-- **Installation** — `pip install -e ".[<benchmark>]"` plus any extra steps (env vars, system packages).
-- **Evaluation** — recommended `lerobot-eval` command with `n_episodes` for reproducible results. `batch_size` defaults to auto; only specify it if needed. Include single-task and multi-task examples if applicable.
-- **Policy inputs and outputs** — observation keys with shapes, action space description.
-- **Recommended evaluation episodes** — how many episodes per task is standard.
-- **Training** — example `lerobot-train` command.
-- **Reproducing published results** — link to pretrained model, eval command, results table (if available).

+# Benchmark Training & Evaluation
+
+This guide explains how to train and evaluate policies on the simulation benchmarks
+integrated in LeRobot: **LIBERO**, **LIBERO-plus**, **MetaWorld**, **RoboCasa**, and **RoboMME**.
+
+The workflow is:
+
+1. Pick one or more benchmarks.
+2. For each benchmark, train a policy on its combined dataset (multi-GPU).
+3. Upload the trained policy to the Hugging Face Hub.
+4. Evaluate the policy on every task suite within that benchmark.
+
+## Prerequisites
+
+Install the benchmark-specific dependencies for the environments you want to evaluate on:
+
+```bash
+# LIBERO (original)
+pip install -e ".[libero]"
+
+# LIBERO-plus
+pip install -e ".[libero_plus]"
+
+# MetaWorld
+pip install -e ".[metaworld]"
+
+# RoboCasa
+pip install -e ".[robocasa]"
+
+# RoboMME
+pip install -e ".[robomme]"
+```
+
+`libero_plus` includes the same EGL probe dependencies as `libero` so headless
+renderer setup is consistent between both installs.
+
+If your environment has CMake build-isolation issues, use the same fallback as
+standard LIBERO installs:
+
+```bash
+PATH=/usr/bin:/bin:$PATH pip install --no-build-isolation -e ".[libero-plus]"
+```
+
+For multi-GPU training you also need [Accelerate](https://huggingface.co/docs/accelerate):
+
+```bash
+pip install accelerate
+```
+
+## Docker-isolated evaluation (EnvHub)
+
+LeRobot eval now supports running the full eval worker in a Docker container
+while keeping policy loading compatible with local checkpoints and local code changes.
+
+Use `lerobot-eval` with `--eval.runtime=docker`:
+
+```bash
+lerobot-eval \
+  --policy.path=outputs/train/my_policy/checkpoints/050000/pretrained_model \
+  --env.type=libero_plus \
+  --eval.runtime=docker \
+  --eval.docker.envhub_ref=envhub://lerobot/libero_plus@v1 \
+  --eval.n_episodes=10 \
+  --eval.batch_size=10
+```
+
+`eval.docker.envhub_ref` is optional. If omitted, LeRobot resolves a default
+image from `env.type`. You can also override the image directly:
+
+```bash
+--eval.docker.image=docker://ghcr.io/huggingface/lerobot-eval-libero-plus:latest
+```
+
+By default (`eval.docker.use_local_code=true`), the local repository is mounted
+in the container and added to `PYTHONPATH`, so edited policy/env code and local
+checkpoints continue to work without rebuilding the image for each change.
+
+Common Docker runtime options:
+
+```bash
+--eval.docker.pull=true \
+--eval.docker.gpus=all \
+--eval.docker.shm_size=8g \
+--eval.docker.use_local_code=true
+```
+
+The benchmark runner supports the same Docker eval path (extra args are
+forwarded to each generated `lerobot-eval` call):
+
+```bash
+lerobot-benchmark eval \
+    --benchmarks libero_plus,robocasa \
+    --hub-user $HF_USER \
+    --n-episodes 50 \
+    --eval.runtime=docker \
+    --eval.docker.pull=true
+```
+
+Build benchmark images locally:
+
+```bash
+make build-eval-images
+```
+
+## Fast single-machine eval tuning
+
+`lerobot-eval` now has two orthogonal throughput knobs:
+
+- `eval.batch_size`: number of sub-envs per task (inside one vector env).
+- `env.max_parallel_tasks`: number of tasks scheduled concurrently.
+- `eval.instance_count`: number of full eval instances (process-level sharding).
+
+Use them in this order:
+
+1. Increase `eval.batch_size` first for per-task throughput.
+2. Then increase `env.max_parallel_tasks` to overlap tasks, while monitoring RAM/VRAM.
+3. Optionally increase `eval.instance_count` for process-level parallelism (best with enough CPU/RAM and small models).
+
+The eval logs print the active scheduler mode (`sequential`, `threaded`, or `batched_lazy`) so you can verify the effective concurrency path.
+
+### Suggested starting points
+
+| Benchmark | Conservative | Faster (single GPU) | Notes |
+|---|---|---|---|
+| `libero` / `libero_plus` | `eval.batch_size=1`, `env.max_parallel_tasks=4` | `eval.batch_size=1`, `env.max_parallel_tasks=16` | For large suite sweeps, increase `max_parallel_tasks` before `batch_size` to avoid MuJoCo memory spikes. |
+| `metaworld` | `eval.batch_size=8`, `env.max_parallel_tasks=1` | `eval.batch_size=16`, `env.max_parallel_tasks=2` | Prefer larger per-task vectorization first. |
+| `robocasa` | `eval.batch_size=4`, `env.max_parallel_tasks=1` | `eval.batch_size=8`, `env.max_parallel_tasks=2` | Rendering/memory can dominate at high image resolution. |
+| `robomme` | `eval.batch_size=4`, `env.max_parallel_tasks=1` | `eval.batch_size=8`, `env.max_parallel_tasks=2` | Start small and scale gradually with task count. |

+  --policy.path=$HF_USER/smolvla_libero_plus \
+  --env.type=libero_plus \
+  --eval.runtime=docker \
+  --eval.docker.envhub_ref=envhub://lerobot/libero_plus@v1 \

+  --eval.docker.shm_size=16g \
+  --eval.n_episodes=1 \
+  --eval.batch_size=1 \
+  --env.max_parallel_tasks=16
+```
+
+## Quick start — single benchmark
+
+Train SmolVLA on LIBERO-plus with 4 GPUs for 50 000 steps:
+
+```bash
+lerobot-benchmark train \
+    --benchmarks libero_plus \
+    --policy-path lerobot/smolvla_base \
+    --hub-user $HF_USER \
+    --num-gpus 4 \
+    --steps 50000 \
+    --batch-size 32 \
+    --wandb
+```
+
+This trains on the combined LIBERO-plus dataset and pushes the checkpoint to
+`$HF_USER/smolvla_libero_plus` on the Hub.
+
+Then evaluate on **all four** LIBERO suites (spatial, object, goal, 10):
+
+```bash
+lerobot-benchmark eval \
+    --benchmarks libero_plus \
+    --hub-user $HF_USER \
+    --n-episodes 50
+```
+
+This automatically runs a separate `lerobot-eval` for each suite.
+
+## Full sweep — multiple benchmarks
+
+Run training **and** evaluation across all benchmarks:
+
+```bash
+lerobot-benchmark all \
+    --benchmarks libero,libero_plus,metaworld,robocasa,robomme \
+    --policy-path lerobot/smolvla_base \
+    --hub-user $HF_USER \
+    --num-gpus 4 \
+    --steps 50000 \
+    --batch-size 32 \
+    --wandb \
+    --push-eval-to-hub
+```
+
+For each benchmark the runner:
+1. Trains a policy on its dataset.
+2. Evaluates on every eval task in the benchmark (e.g. 4 suites for LIBERO).
+3. Pushes HF-native `.eval_results` rows (and optional artifacts) to the Hub.
+
+<Tip>
+
+Use `--dry-run` to print the exact `lerobot-train` / `lerobot-eval` commands without executing them, so you can inspect or modify them before running.
+
+</Tip>
+
+## Using the CLI directly (without the benchmark runner)
+
+You can also compose the commands yourself. The benchmark runner is a thin wrapper; here is what it does under the hood.
+
+### Training
+
+```bash
+accelerate launch \
+    --multi_gpu \
+    --num_processes=4 \
+    $(which lerobot-train) \
+    --policy.path=lerobot/smolvla_base \
+    --dataset.repo_id=$HF_USER/libero_plus \
+    --policy.repo_id=$HF_USER/smolvla_libero_plus \
+    --env.type=libero_plus \
+    --env.task=libero_spatial \
+    --steps=50000 \
+    --batch_size=32 \
+    --eval_freq=10000 \
+    --save_freq=10000 \
+    --output_dir=outputs/train/smolvla_libero_plus \
+    --job_name=smolvla_libero_plus \
+    --policy.push_to_hub=true \
+    --wandb.enable=true
+```
+
+### Evaluation (run once per suite)
+
+```bash
+for SUITE in libero_spatial libero_object libero_goal libero_10; do
+    lerobot-eval \
+        --policy.path=$HF_USER/smolvla_libero_plus \
+        --env.type=libero_plus \
+        --env.task=$SUITE \
+        --eval.n_episodes=50 \
+        --eval.batch_size=10 \
+        --output_dir=outputs/eval/smolvla_libero_plus/$SUITE \
+        --policy.device=cuda \
+        --push_to_hub=true \
+        --benchmark_dataset_id=lerobot/sim-benchmarks
+done
+```
+
+## Available benchmarks
+
+| Benchmark | Env type | Dataset | Eval tasks | Action dim |
+|---|---|---|---|---|
+| `libero` | `libero` | `{hub_user}/libero` | spatial, object, goal, 10 | 7 |
+| `libero_plus` | `libero_plus` | `{hub_user}/libero_plus` | spatial, object, goal, 10 | 7 |
+| `metaworld` | `metaworld` | `{hub_user}/metaworld` | push-v2 | 4 |
+| `robocasa` | `robocasa` | `{hub_user}/robocasa` | PickPlaceCounterToCabinet | 12 |
+| `robomme` | `robomme` | `{hub_user}/robomme` | PickXtimes | 8 |
+
+Run `lerobot-benchmark list` to see the full registry with all eval tasks.
+
+## Policy naming convention
+
+The benchmark runner stores trained policies under:
+
+```
+{hub_user}/{policy_name}_{benchmark}
+```
+
+The default `--policy-name` is `smolvla`. So training on `libero_plus` as user `alice` produces `alice/smolvla_libero_plus`.
+
+You can override this, e.g. `--policy-name pi05` if training π₀.₅ instead.
+
+## Multi-GPU considerations
+
+The effective batch size is `batch_size × num_gpus`. With `--batch-size=32` and
+`--num-gpus=4`, you train with an effective batch of 128 per step. LeRobot does **not**
+auto-scale the learning rate; see the [Multi-GPU Training guide](./multi_gpu_training) for
+details on when and how to adjust it.
+
+## Custom benchmarks
+
+To add a new benchmark, edit the `BENCHMARK_REGISTRY` in
+`src/lerobot/scripts/lerobot_benchmark.py`:
+
+```python
+from lerobot.scripts.lerobot_benchmark import BenchmarkEntry, BENCHMARK_REGISTRY
+
+BENCHMARK_REGISTRY["my_benchmark"] = BenchmarkEntry(
+    dataset_repo_id="{hub_user}/my_dataset",
+    env_type="my_env",
+    env_task="MyDefaultTask",
+    eval_tasks=["TaskA", "TaskB", "TaskC"],
+)
+```
+
+Then use `--benchmarks my_benchmark` as usual. The runner will train once and
+evaluate separately on TaskA, TaskB, and TaskC.
+
+## Outputs
+
+After training and evaluation, your outputs directory looks like:
+
+```
+outputs/
+├── train/
+│   ├── smolvla_libero/
+│   │   ├── checkpoints/
+│   │   └── ...

+    │   └── libero_10/
+    ├── smolvla_robocasa/
+    └── smolvla_robomme/
+```
+
+Each `eval_info.json` contains per-episode rewards, success rates, and aggregate metrics.
+
+## HF Eval Results + Leaderboard
+
+LeRobot publishes benchmark scores using Hugging Face's native
+`/.eval_results/*.yaml` format, which powers model-page eval cards and
+benchmark leaderboards.
+
+Add `--push-eval-to-hub` to push results after each eval run:
+
+```bash
+lerobot-benchmark eval \
+    --benchmarks libero_plus,robocasa \
+    --hub-user $HF_USER \
+    --benchmark-dataset-id lerobot/sim-benchmarks \
+    --push-eval-to-hub
+```
+
+This writes one or more files under `.eval_results/` in the model repo, for example:
+
+```yaml
+- dataset:
+    id: lerobot/sim-benchmarks
+    task_id: libero_plus/spatial
+  value: 82.4
+  notes: lerobot-eval
+```
+
+Notes:
+- `--benchmark-dataset-id` points to your consolidated benchmark dataset repo.
+- `task_id` values are derived from `env.type` and evaluated suite/task names.
+- Eval artifacts (`eval_info.json`, `eval_config.json`, videos) are still uploaded
+  for provenance, but leaderboard ranking comes from `.eval_results`.
+
+## Passing extra arguments
+
+Any arguments after the recognized flags are forwarded to `lerobot-train` or
+`lerobot-eval`.
+
+Example (training): use PEFT/LoRA during training.
+
+```bash
+lerobot-benchmark train \
+    --benchmarks libero_plus \
+    --policy-path lerobot/smolvla_base \
+    --hub-user $HF_USER \
+    --num-gpus 4 \
+    --steps 50000 \
+    --peft.method_type=LORA --peft.r=16
+```
+
+Example (evaluation): forward Docker runtime flags to each `lerobot-eval` call.
+
+```bash
+lerobot-benchmark eval \
+    --benchmarks libero_plus \
+    --hub-user $HF_USER \
+    --eval.runtime=docker \
+    --eval.docker.envhub_ref=envhub://lerobot/libero_plus@v1
+```

+# Using Subtasks in LeRobot Datasets
+
+Subtask support in robotics datasets has proven effective in improving robot reasoning and understanding. Subtasks are particularly useful for:
+
+- **Hierarchical policies**: Building policies that include subtask predictions to visualize robot reasoning in real time
+- **Reward modeling**: Helping reward models understand task progression (e.g., SARM-style stage-aware reward models)
+- **Task decomposition**: Breaking down complex manipulation tasks into atomic, interpretable steps
+
+LeRobotDataset now supports subtasks as part of its dataset structure, alongside tasks.
+
+## What are Subtasks?
+
+While a **task** describes the overall goal (e.g., "Pick up the apple and place it in the basket"), **subtasks** break down the execution into finer-grained steps:
+
+1. "Approach the apple"
+2. "Grasp the apple"
+3. "Lift the apple"
+4. "Move to basket"
+5. "Release the apple"
+
+Each frame in the dataset can be annotated with its corresponding subtask, enabling models to learn and predict these intermediate stages.

+
+## Dataset Structure
+
+Subtask information is stored in the dataset metadata:
+
+```
+my-dataset/
+├── data/
+│   └── ...
+├── meta/
+│   ├── info.json
+│   ├── stats.json
+│   ├── tasks.parquet
+│   ├── subtasks.parquet      # Subtask index → subtask string mapping
+│   └── episodes/
+│       └── ...
+└── videos/
+    └── ...
+```
+
+### Subtasks Parquet File
+
+The `meta/subtasks.parquet` file maps subtask indices to their natural language descriptions:
+
+| subtask_index | subtask (index column) |
+| ------------- | ---------------------- |
+| 0             | "Approach the apple"   |
+| 1             | "Grasp the apple"      |
+| 2             | "Lift the apple"       |
+| ...           | ...                    |
+
+### Frame-Level Annotations
+
+Each frame in the dataset can include a `subtask_index` field that references the subtasks parquet file:
+
+```python
+# Example frame data in the parquet file
+{
+    "index": 42,
+    "timestamp": 1.4,
+    "episode_index": 0,
+    "task_index": 0,
+    "subtask_index": 2,  # References "Lift the apple"
+    "observation.state": [...],
+    "action": [...],
+}
+```
+
+## Annotating Datasets with Subtasks
+
+We provide a HuggingFace Space for easily annotating any LeRobotDataset with subtasks:
+
+**[https://huggingface.co/spaces/lerobot/annotate](https://huggingface.co/spaces/lerobot/annotate)**
+
+After completing your annotation:
+
+1. Click "Push to Hub" to upload your annotated dataset
+2. You can also run the annotation space locally by following the instructions at [github.com/huggingface/lerobot-annotate](https://github.com/huggingface/lerobot-annotate)
+
+## Loading Datasets with Subtasks
+
+When you load a dataset with subtask annotations, the subtask information is automatically available:
+
+```python
+from lerobot.datasets.lerobot_dataset import LeRobotDataset
+
+# Load a dataset with subtask annotations
+dataset = LeRobotDataset("jadechoghari/collect-fruit-annotated")
+
+# Access a sample
+sample = dataset[100]
+
+# The sample includes both task and subtask information
+print(sample["task"])        # "Collect the fruit"
+print(sample["subtask"])     # "Grasp the apple"
+print(sample["task_index"])  # tensor(0)
+print(sample["subtask_index"])  # tensor(2)
+```
+
+### Checking for Subtask Support
+
+You can check if a dataset has subtask annotations:
+
+```python
+# Check if subtasks are available
+has_subtasks = (
+    "subtask_index" in dataset.features
+    and dataset.meta.subtasks is not None
+)
+
+if has_subtasks:
+    print(f"Dataset has {len(dataset.meta.subtasks)} unique subtasks")
+    print("Subtasks:", list(dataset.meta.subtasks.index))
+```
+
+## Using Subtasks for Training
+
+### With the Tokenizer Processor
+
+The `TokenizerProcessor` automatically handles subtask tokenization for Vision-Language Action (VLA) models:
+
+```python
+from lerobot.processor.tokenizer_processor import TokenizerProcessor
+from lerobot.processor.pipeline import ProcessorPipeline
+
+# Create a tokenizer processor
+tokenizer_processor = TokenizerProcessor(
+    tokenizer_name_or_path="google/paligemma-3b-pt-224",
+    padding="max_length",
+    max_length=64,
+)
+
+# The processor will automatically tokenize subtasks if present in the batch
+# and add them to the observation under:
+# - "observation.subtask.tokens"
+# - "observation.subtask.attention_mask"
+```
+
+When subtasks are available in the batch, the tokenizer processor adds:
+
+- `observation.subtask.tokens`: Tokenized subtask text
+- `observation.subtask.attention_mask`: Attention mask for the subtask tokens
+
+### DataLoader with Subtasks
+
+```python
+import torch
+from lerobot.datasets.lerobot_dataset import LeRobotDataset
+
+dataset = LeRobotDataset("jadechoghari/collect-fruit-annotated")
+
+dataloader = torch.utils.data.DataLoader(
+    dataset,
+    batch_size=16,
+    shuffle=True,
+)
+
+for batch in dataloader:
+    # Access subtask information in the batch
+    subtasks = batch["subtask"]  # List of subtask strings
+    subtask_indices = batch["subtask_index"]  # Tensor of subtask indices
+
+    # Use for training hierarchical policies or reward models
+    print(f"Batch subtasks: {set(subtasks)}")
+```
+
+## Example Datasets with Subtask Annotations
+
+Try loading a dataset with subtask annotations:
+
+```python
+from lerobot.datasets.lerobot_dataset import LeRobotDataset
+
+# Example dataset with subtask annotations
+dataset = LeRobotDataset("jadechoghari/collect-fruit-annotated")
+
+# Explore the subtasks
+print("Available subtasks:")
+for subtask_name in dataset.meta.subtasks.index:
+    print(f"  - {subtask_name}")
+
+# Get subtask distribution
+subtask_counts = {}
+for i in range(len(dataset)):
+    sample = dataset[i]
+    subtask = sample["subtask"]
+    subtask_counts[subtask] = subtask_counts.get(subtask, 0) + 1
+
+print("\nSubtask distribution:")
+for subtask, count in sorted(subtask_counts.items(), key=lambda x: -x[1]):
+    print(f"  {subtask}: {count} frames")

+
+## Use Cases
+
+### 1. Hierarchical Policy Training
+
+Train policies that predict both actions and current subtask:
+
+```python
+class HierarchicalPolicy(nn.Module):
+    def __init__(self, num_subtasks):
+        super().__init__()
+        self.action_head = nn.Linear(hidden_dim, action_dim)
+        self.subtask_head = nn.Linear(hidden_dim, num_subtasks)
+
+    def forward(self, observations):
+        features = self.encoder(observations)
+        actions = self.action_head(features)
+        subtask_logits = self.subtask_head(features)
+        return actions, subtask_logits
+```
+
+### 2. Stage-Aware Reward Modeling (SARM)
+
+Build reward models that understand task progression:
+
+```python
+# SARM predicts:
+# - Stage: Which subtask is being executed (discrete)
+# - Progress: How far along the subtask (continuous 0-1)
+
+class SARMRewardModel(nn.Module):
+    def forward(self, observations):
+        features = self.encoder(observations)
+        stage_logits = self.stage_classifier(features)
+        progress = self.progress_regressor(features)
+        return stage_logits, progress
+```
+
+### 3. Progress Visualization
+
+Monitor robot execution by tracking subtask progression:
+
+```python
+def visualize_execution(model, observations):
+    for t, obs in enumerate(observations):
+        action, subtask_logits = model(obs)
+        predicted_subtask = subtask_names[subtask_logits.argmax()]
+        print(f"t={t}: Executing '{predicted_subtask}'")
+```

-# Human-In-the-Loop Data Collection
-
-Human-In-the-Loop (HIL) data collection lets you improve a trained policy by deploying it on a real robot while a human operator monitors and intervenes when needed. The intervention data (recovery movements and corrections) is recorded alongside autonomous segments, producing a richer training dataset that teaches the policy how to handle failures.
-
----
-
-## Why Human-In-the-Loop?
-
-Standard behavioral cloning trains policies on successful demonstrations only. During deployment, small errors can compound and push the robot into states never seen during training (distribution shift). HIL data collection addresses this by:
-
-- Running the trained policy on the real robot
-- Having a human intervene when the robot is about to fail
-- Recording the human's recovery and correction as training data
-- Fine-tuning the policy on the combined dataset
-
-This produces a policy that not only knows how to perform the task, but also how to recover when things go wrong.
-
----
-
-## How It Works
-
-During a HIL session, the human operator follows this loop within each episode:
-
-1. **Watch** the policy run autonomously
-2. **Pause** when failure is imminent, the robot holds its position
-3. **Take control** and teleoperate the robot back to a good state (recovery), then correct the behavior
-4. **Return control to the policy**, the policy resumes autonomous execution
-5. Repeat steps 2–4 as many times as needed during the episode
-6. **End the episode** when the task is complete, save and move on to the next rollout
-
-Both autonomous and human-controlled segments are recorded. The policy and human can alternate control multiple times within a single episode, and the episode continues from the current state after each handoff (no reset required just because intervention happened). This captures autonomous execution, recovery, and correction in one continuous trajectory. After collection, the combined dataset (original demonstrations + HIL data) is used to fine-tune the policy.
-
-This process can be repeated iteratively: deploy, collect, fine-tune, repeat. Each round targets the current policy's failure modes.
-

-## Hardware Requirements
-
-### Teleoperator Requirements
-
-The `examples/hil` HIL scripts require **teleoperators with active motors** that can:
-
-- Enable/disable torque programmatically
-- Move to target positions (to mirror the robot state when pausing)
-
-**Compatible teleoperators in the current `examples/hil` scripts:**
-
-- `openarm_mini` - OpenArm Mini
-- `so_leader` - SO100 / SO101 leader arm
-
-> [!IMPORTANT]
-> The provided `examples/hil` commands default to `bi_openarm_follower` + `openarm_mini`.
-> `so_follower` + `so_leader` configs are also registered and can be used via CLI flags.

-## Script
-
-A single script handles both synchronous and RTC-based inference. Toggle RTC with `--rtc.enabled=true`:
-
-| Mode                     | Flag                 | Models                |
-| ------------------------ | -------------------- | --------------------- |
-| Standard (default)       | _(no flag needed)_   | ACT, Diffusion Policy |
-| Real-Time Chunking (RTC) | `--rtc.enabled=true` | Pi0, Pi0.5, SmolVLA   |
-
----
-
-## Step-by-Step Guide
-
-### Step 1: Pre-train a Base Policy
-
-First, train a policy on your demonstration dataset:
-
-```bash
-python src/lerobot/scripts/lerobot_train.py \
-    --dataset.repo_id=your-username/demo-dataset \
-    --policy.type=pi0 \
-    --output_dir=outputs/pretrain \
-    --batch_size=32 \
-    --steps=50000
-```
-
-### Step 2: Collect HIL Data
-
-**Standard inference (ACT, Diffusion Policy):**
-
-```bash
-python examples/hil/hil_data_collection.py \
-    --robot.type=bi_openarm_follower \
-    --robot.left_arm_config.port=can1 \
-    --robot.left_arm_config.side=left \
-    --robot.right_arm_config.port=can0 \
-    --robot.right_arm_config.side=right \
-    --robot.cameras='{left_wrist: {type: opencv, index_or_path: "/dev/video0", width: 1280, height: 720, fps: 30}, right_wrist: {type: opencv, index_or_path: "/dev/video4", width: 1280, height: 720, fps: 30}, base: {type: opencv, index_or_path: "/dev/video2", width: 640, height: 480, fps: 30}}' \
-    --teleop.type=openarm_mini \
-    --teleop.port_left=/dev/ttyACM0 \
-    --teleop.port_right=/dev/ttyACM1 \
-    --policy.path=outputs/pretrain/checkpoints/last/pretrained_model \
-    --dataset.repo_id=your-username/hil-dataset \
-    --dataset.single_task="Fold the T-shirt properly" \
-    --dataset.fps=30 \
-    --dataset.episode_time_s=1000 \
-    --dataset.num_episodes=50 \
-    --interpolation_multiplier=2
-```
-
-**With RTC for large models (Pi0, Pi0.5, SmolVLA):**
-
-For models with high inference latency, enable RTC for smooth execution:
-
-```bash
-python examples/hil/hil_data_collection.py \
-    --rtc.enabled=true \
-    --rtc.execution_horizon=20 \
-    --rtc.max_guidance_weight=5.0 \
-    --rtc.prefix_attention_schedule=LINEAR \
-    --robot.type=bi_openarm_follower \
-    --robot.left_arm_config.port=can1 \
-    --robot.left_arm_config.side=left \
-    --robot.right_arm_config.port=can0 \
-    --robot.right_arm_config.side=right \
-    --robot.cameras='{left_wrist: {type: opencv, index_or_path: "/dev/video0", width: 1280, height: 720, fps: 30}, right_wrist: {type: opencv, index_or_path: "/dev/video4", width: 1280, height: 720, fps: 30}, base: {type: opencv, index_or_path: "/dev/video2", width: 640, height: 480, fps: 30}}' \
-    --teleop.type=openarm_mini \
-    --teleop.port_left=/dev/ttyACM0 \
-    --teleop.port_right=/dev/ttyACM1 \
-    --policy.path=outputs/pretrain/checkpoints/last/pretrained_model \
-    --dataset.repo_id=your-username/hil-rtc-dataset \
-    --dataset.single_task="Fold the T-shirt properly" \
-    --dataset.fps=30 \
-    --dataset.episode_time_s=1000 \
-    --dataset.num_episodes=50 \
-    --interpolation_multiplier=3
-```
-
-**Controls (Conceptual):**
-
-The interaction model is:
-
-- **Pause input**: pause autonomous policy execution
-- **Takeover input**: transfer control to the human operator and record intervention data
-- **Return-to-policy input**: hand control back to the policy and continue the same episode
-- **Episode control inputs**: save/re-record/stop/reset as needed
-
-Exact key/pedal bindings can differ across scripts and hardware integrations. Use each script's printed controls as the source of truth for the concrete mapping on your setup.
-
-**The HIL Protocol:**
-
-1. Watch the policy run autonomously (teleop is idle/free)
-2. When you see imminent failure, trigger the **pause input**
-   - Policy stops
-   - Teleoperator moves to match robot position (torque enabled)
-   - No frames recorded during pause
-3. Trigger the **takeover input** to take control
-   - Teleoperator torque disabled, free to move
-   - **Recovery**: Teleoperate the robot back to a good state
-   - **Correction**: Correct the behavior
-   - All movements are recorded
-4. Trigger the **return-to-policy input**
-   - Policy resumes autonomous execution from the current state
-   - You can intervene again at any time (repeat steps 2–4)
-5. End and save the episode when the task is complete (or episode time limit is reached)
-6. **Reset**: Teleop moves to robot position, you can move the robot to the starting position
-7. Start the next episode
-
-**Foot Pedal Setup (Linux):**
-
-If using a USB foot pedal (PCsensor FootSwitch), ensure access:
-
-```bash
-sudo setfacl -m u:$USER:rw /dev/input/by-id/usb-PCsensor_FootSwitch-event-kbd
-```
-
-### Step 3: Fine-tune the Policy
-
-Fine-tune on the **combined** dataset (`demo-dataset` + `hil-dataset` merged together):
-
-```bash
-python src/lerobot/scripts/lerobot_train.py \
-    --dataset.repo_id=your-username/hil-dataset \
-    --policy.type=pi0 \
-    --policy.pretrained_path=outputs/pretrain/checkpoints/last/pretrained_model \
-    --output_dir=outputs/hil_finetune \
-    --steps=20000
-```
-
-Then deploy the fine-tuned policy and repeat from Step 2 to target its remaining failure modes.

-## Tips for Effective HIL Collection
-
-### When to Intervene
-
-Intervene when you see:
-
-- Robot about to make an irreversible mistake
-- Robot hesitating or showing uncertain behavior
-- Robot deviating from the expected trajectory
-
-### Recovery: Teleoperating Back to a Good State
-
-During recovery, teleoperate the robot back to a state where:
-
-- The robot is in a familiar, in-distribution configuration
-- The current subtask can still be completed
-- The recovery trajectory itself is informative training data
-
-### Quality of Corrections
-
-During correction:
-
-- Provide **confident, clean** trajectories
-- Complete the current subtask fully
-- Don't overcorrect or add unnecessary movements
-
----
-
-## Related Work
-
-This HIL data collection approach builds on ideas from interactive imitation learning:
-
-- **DAgger** (Ross et al., 2011) introduced the core idea: instead of only training on expert demonstrations, query the expert for corrections on states the _learner_ visits. This breaks the compounding-error cycle of standard behavioral cloning by iteratively collecting on-policy data.
-
-- **HG-DAgger** (Kelly et al., 2019) made this practical for robotics: a human expert monitors the robot and only intervenes when needed, rather than labeling every state. The gating between autonomous and human control is exactly the pause → takeover → return-to-policy loop used in the scripts here.
-
-- **RaC** (Hu et al., 2025) scales this loop to long-horizon tasks by explicitly decomposing interventions into **recovery** (teleoperating back to a good state) and **correction** (demonstrating the right behavior from there). This decomposition is the protocol followed by the HIL scripts in `examples/hil`.
-
-- **π0.6/RECAP** (Physical Intelligence, 2025) applies the same iterative collect-and-finetune loop at scale with VLA models, showing that even large pretrained policies benefit substantially from targeted human corrections on their own failure modes. π0.6 is trained using RECAP.

-# Language columns and recipes
-
-LeRobot stores reusable language annotations directly next to frame data in `data/chunk-*/file-*.parquet`.
-The two optional columns are:
-
-- `language_persistent`: a list of rows broadcast across every frame in an episode for state that remains active, such as `subtask`, `plan`, and `memory`.
-- `language_events`: a list of rows only on the exact frame where an event was emitted, such as `interjection`, `vqa`, and speech tool calls.
-
-Both columns share the same row shape (event rows omit `timestamp` because the
-frame the row sits on already provides it):
-
-```text
-role: string
-content: string | null
-style: string | null
-timestamp: float64        # persistent rows only
-camera: string | null     # observation.images.* feature key, view-dependent rows only
-tool_calls: list[Json] | null
-```
-
-The `camera` field tags rows whose `content` is grounded in a specific camera
-view. Rows of view-dependent styles (`vqa`, and the reserved `motion` /
-`trace`) MUST set `camera` to the matching `observation.images.*` feature key.
-Rows of every other style MUST leave `camera` as `null`. Pipeline writers and
-the validator enforce this via `validate_camera_field(style, camera)`.
-
-`meta/tasks.parquet` remains the canonical source for the task. The special `${task}` recipe binding always reads that task string and does not depend on language annotations.
-
-## Architecture
-
-The language stack has three layers:
-
-1. `lerobot.datasets.language` defines the schema, style registry, and `column_for_style`.
-2. `lerobot.datasets.language_render` resolves rows and renders messages.
-3. `RenderMessagesStep` turns dataset samples into `messages`, `message_streams`, and `target_message_indices`.
-
-`LeRobotDataset` stays recipe-agnostic. It passes `language_persistent` and `language_events` through when present, and unannotated datasets keep their existing behavior.
-
-## Temporal semantics
-
-Persistent styles are active after emission until replaced:
-
-- `active_at(t, style=subtask)`
-- `nth_prev(style=memory, offset=1)`
-- `nth_next(style=subtask, offset=1)`
-
-Event styles only exist on their exact timestamp:
-
-- `emitted_at(t, style=interjection)`
-- `emitted_at(t, style=vqa, role=user, camera=observation.images.top)`
-- `emitted_at(t, role=assistant, tool_name=say)`
-
-Exact event matching has no tolerance window, so writers must stamp event rows with frame timestamps from the parquet data.
-
-## View-dependent resolution
-
-For view-dependent styles (`vqa`, `motion`, `trace`), the resolver gains a
-`camera=` filter parallel to `role=` and `tool_name=`. Datasets with multiple
-cameras typically emit one (`vqa`, `user`) + (`vqa`, `assistant`) pair per
-camera at the same timestamp; without `camera=`, those resolvers see two
-matches and raise an ambiguity error. Recipes consume each camera through its
-own binding plus a matching image block, e.g.
-
-```yaml
-ask_vqa_top:
-  bindings:
-    vqa_query: "emitted_at(t, style=vqa, role=user, camera=observation.images.top)"
-    vqa: "emitted_at(t, style=vqa, role=assistant, camera=observation.images.top)"
-  messages:
-    - role: user
-      stream: high_level
-      if_present: vqa_query
-      content:
-        - { type: image, feature: observation.images.top }
-        - { type: text, text: "${vqa_query}" }
-    - { role: assistant, content: "${vqa}", stream: high_level, target: true, if_present: vqa }
-```
-
-Add one such sub-recipe per camera the dataset records.
-
-## Recipe anatomy
-
-Recipes are YAML files backed by `TrainingRecipe` and `MessageTurn`.
-
-```yaml
-messages:
-  - { role: user, content: "${task}", stream: high_level }
-  - { role: assistant, content: "${subtask}", stream: low_level, target: true }
-```
-
-Rendered samples use HF-style chat messages plus LeRobot sidecars:
-
-```python
-sample["messages"]
-sample["message_streams"]
-sample["target_message_indices"]
-```
-
-The renderer does not apply a tokenizer chat template. Policy processors decide how to serialize the messages for their backbone.
-
-## Blends
-
-Blend recipes select one weighted sub-recipe deterministically from the sample index.
-The canonical `recipes/pi05_hirobot.yaml` combines memory updates, interjection responses, high-level subtask prediction, low-level execution, and VQA.
-
-## Graceful absence
-
-If both language columns are missing, `None`, or empty, `RenderMessagesStep` is a no-op.
-If an event-scoped branch is selected on a frame without the required event row, rendering returns `None`, allowing a loader to retry another sample.

The idea is that robots won’t just be pretrained once in a factory, they’ll need to keep learning and adapting with their human users over time.

+
+To make progress on this challenge, LIBERO provides a set of standardized tasks that focus on **knowledge transfer**: how well a robot can apply what it has already learned to new situations. By evaluating on LIBERO, different algorithms can be compared fairly and researchers can build on each other’s work.
+
+LIBERO includes **five task suites**:
+
+- **LIBERO-Spatial (`libero_spatial`)** – tasks that require reasoning about spatial relations.
+- **LIBERO-Object (`libero_object`)** – tasks centered on manipulating different objects.
+- **LIBERO-Goal (`libero_goal`)** – goal-conditioned tasks where the robot must adapt to changing targets.
+- **LIBERO-90 (`libero_90`)** – 90 short-horizon tasks from the LIBERO-100 collection.
+- **LIBERO-Long (`libero_10`)** – 10 long-horizon tasks from the LIBERO-100 collection.
+
+Together, these suites cover **130 tasks**, ranging from simple object manipulations to complex multi-step scenarios. LIBERO is meant to grow over time, and to serve as a shared benchmark where the community can test and improve lifelong learning algorithms.

+## Evaluating with LIBERO
 
-LIBERO includes **five task suites** covering **130 tasks**, ranging from simple object manipulations to complex multi-step scenarios:
+At **LeRobot**, we ported [LIBERO](https://github.com/Lifelong-Robot-Learning/LIBERO) into our framework and used it mainly to **evaluate [SmolVLA](https://huggingface.co/docs/lerobot/en/smolvla)**, our lightweight Vision-Language-Action model.
 
-| Suite          | CLI name         | Tasks | Description                                        |

-| LIBERO-Long    | `libero_10`      | 10    | Long-horizon tasks from the LIBERO-100 collection  |
+LIBERO is now part of our **multi-eval supported simulation**, meaning you can benchmark your policies either on a **single suite of tasks** or across **multiple suites at once** with just a flag.
 
-## Installation
-
-After following the LeRobot installation instructions:
-
-```bash
-pip install -e ".[libero]"
-```
-
-<Tip>
-LIBERO requires Linux (`sys_platform == 'linux'`). LeRobot uses MuJoCo for simulation — set the rendering backend before training or evaluation:
-
-```bash
-export MUJOCO_GL=egl  # for headless servers (HPC, cloud)
-```
-
-</Tip>
-
-## Evaluation
-
-### Default evaluation (recommended)
-
-Evaluate across the four standard suites (10 episodes per task):

-
-<Tip warning={true}>
-  Installing LIBERO-plus **replaces** vanilla LIBERO — it uninstalls `hf-libero`
-  so that `import libero` resolves to the LIBERO-plus fork. You cannot have both
-  installed at the same time. To switch back to vanilla LIBERO, uninstall the
-  fork and reinstall with `pip install -e ".[libero]"`.
-</Tip>
-
-## Installation
-
-### System dependencies (Linux only)
-
-```bash
-sudo apt install libexpat1 libfontconfig1-dev libmagickwand-dev
-```
-
-### Python package
-
-```bash
-pip install -e ".[libero]" "robosuite==1.4.1" bddl easydict mujoco wand scikit-image gym
-git clone https://github.com/sylvestf/LIBERO-plus.git
-cd LIBERO-plus && pip install --no-deps -e .
-pip uninstall -y hf-libero  # so `import libero` resolves to the fork
-```
-
-LIBERO-plus is installed from its GitHub fork rather than a pyproject extra — the fork ships as a namespace package that pip can't handle, so it must be cloned and added to `PYTHONPATH`. See `docker/Dockerfile.benchmark.libero_plus` for the canonical install. MuJoCo is required, so only Linux is supported.
-
-<Tip>
-Set the MuJoCo rendering backend before running evaluation:
-
-```bash
-export MUJOCO_GL=egl   # headless / HPC / cloud
-```
-
-</Tip>
-
-### Download LIBERO-plus assets
-
-LIBERO-plus ships its extended asset pack separately. Download `assets.zip` from the [Hugging Face dataset](https://huggingface.co/datasets/Sylvest/LIBERO-plus/tree/main) and extract it into the LIBERO-plus package directory:
-
-```bash
-# After installing the package, find where it was installed:
-python -c "import libero; print(libero.__file__)"
-# Then extract assets.zip into <package_root>/libero/assets/
-```
-
-## Evaluation
-
-### Default evaluation (recommended)
-
-Evaluate across the four standard suites (10 episodes per task):

-- `--env.task_ids` restricts to specific task indices (`[0]`, `[1,2,3]`, etc.). Omit to run all tasks in the suite.
-- `--eval.batch_size` controls how many environments run in parallel.
-- `--eval.n_episodes` sets how many episodes to run per task.
-
-### Multi-suite evaluation
-
-Benchmark a policy across multiple suites at once by passing a comma-separated list:
-

-  --policy.path="your-policy-id" \
-  --env.type=libero_plus \
-  --env.task=libero_spatial,libero_object \
-  --eval.batch_size=1 \
-  --eval.n_episodes=10
-```
-
-### Control mode
-
-LIBERO-plus supports two control modes — `relative` (default) and `absolute`. Different VLA checkpoints are trained with different action parameterizations, so make sure the mode matches your policy:
-
-```bash
---env.control_mode=relative   # or "absolute"
-```
-
-### Policy inputs and outputs
-
-**Observations:**
-
-- `observation.state` — 8-dim proprioceptive features (eef position, axis-angle orientation, gripper qpos)
-- `observation.images.image` — main camera view (`agentview_image`), HWC uint8
-- `observation.images.image2` — wrist camera view (`robot0_eye_in_hand_image`), HWC uint8
-
-**Actions:**
-
-- Continuous control in `Box(-1, 1, shape=(7,))` — 6D end-effector delta + 1D gripper

-## Available tasks
+## Why Meta-World matters
 
-Meta-World provides 50 tasks organized into difficulty groups. In LeRobot, you can evaluate on individual tasks, difficulty groups, or the full MT50 suite:
+- **Diverse, realistic tasks.** Meta-World bundles a large suite of simulated manipulation tasks (50 in the MT50 suite) using everyday objects and a common tabletop Sawyer arm. This diversity exposes algorithms to a wide variety of dynamics, contacts and goal specifications while keeping a consistent control and observation structure.
+- **Focus on generalization and multi-task learning.** By evaluating across task distributions that share structure but differ in goals and objects, Meta-World reveals whether an agent truly learns transferable skills rather than overfitting to a narrow task.
+- **Standardized evaluation protocol.** It provides clear evaluation modes and difficulty splits, so different methods can be compared fairly across easy, medium, hard and very-hard regimes.
+- **Empirical insight.** Past evaluations on Meta-World show impressive progress on some fronts, but also highlight that current multi-task and meta-RL methods still struggle with large, diverse task sets. That gap points to important research directions.

+## What it enables in LeRobot
 
-You can also pass individual task names directly (e.g., `assembly-v3`, `dial-turn-v3`).
+In LeRobot, you can evaluate any policy or vision-language-action (VLA) model on Meta-World tasks and get a clear success-rate measure. The integration is designed to be straightforward:

-## Evaluation

-
-Evaluate on a specific task:
-
-```bash
-lerobot-eval \
-  --policy.path="your-policy-id" \
-  --env.type=metaworld \
-  --env.task=assembly-v3 \
-  --eval.batch_size=1 \
-  --eval.n_episodes=10
-```
-
-### Multi-task evaluation
-
-Evaluate across multiple tasks or difficulty groups:
-
-```bash
-lerobot-eval \
-  --policy.path="your-policy-id" \
-  --env.type=metaworld \
-  --env.task=assembly-v3,dial-turn-v3,handle-press-side-v3 \
-  --eval.batch_size=1 \
-  --eval.n_episodes=10
-```
-
-- `--env.task` accepts explicit task lists (comma-separated) or difficulty groups (e.g., `easy`, `medium`, `hard`, `very_hard`).
-- `--eval.batch_size` controls how many environments run in parallel.
-- `--eval.n_episodes` sets how many episodes to run per task.
-
-### Policy inputs and outputs
-
-**Observations:**
-
-- `observation.image` — single camera view (`corner2`), 480x480 HWC uint8
-- `observation.state` — 4-dim proprioceptive state (end-effector position + gripper)
-
-**Actions:**
-
-- Continuous control in `Box(-1, 1, shape=(4,))` — 3D end-effector delta + 1D gripper
-
-### Recommended evaluation episodes
-
-For reproducible benchmarking, use **10 episodes per task**. For the full MT50 suite this gives 500 total episodes. If you care about generalization, run on the full MT50 — it is intentionally challenging and reveals strengths/weaknesses better than a few narrow tasks.

-# Multitask DiT Policy
-
-Multitask Diffusion Transformer (DiT) Policy is an evolution of the original Diffusion Policy architecture, which leverages a large DiT with text and vision conditioning for multitask robot learning. This implementation supports both diffusion and flow matching objectives for action generation, enabling robots to perform diverse manipulation tasks conditioned on language instructions.
-
-## Model Overview
-
-The model uses:
-
-- **CLIP Vision Encoder**: Processes RGB images from multiple camera views
-- **CLIP Text Encoder**: Encodes language task instructions (frozen weights with learnable projection)
-- **Diffusion Transformer**: Predicts action sequences conditioned on observations and language
-- **Two Objectives**: Supports both diffusion (DDPM/DDIM) and flow matching for action generation
-
-This model is exciting because you can achieve extremely high dexterity, competitive with multi-billion parameter
-VLAs, with only ~450M parameters and significantly less training.
-
-## Installation Requirements
-
-Multitask DiT Policy has additional dependencies. Install it with:
-
-```bash
-pip install lerobot[multi_task_dit]
-```
-
-This will install all necessary dependencies including the HuggingFace Transformers library for CLIP models.
-
-## Usage
-
-To use Multitask DiT in your LeRobot configuration, specify the policy type as:
-
-```python
-policy.type=multi_task_dit
-```
-
-## Training
-
-### Basic Training Command
-
-Here's a complete training command for training Multitask DiT on your dataset:
-
-```bash
-lerobot-train \
-  --dataset.repo_id=YOUR_DATASET \
-  --output_dir=./outputs/multitask_dit_training \
-  --batch_size=32 \
-  --steps=5000 \
-  --save_freq=500 \
-  --log_freq=100 \
-  --policy.type=multi_task_dit \
-  --policy.device=cuda \
-  --policy.repo_id="HF_USER/multitask-dit-your-robot" \
-  --wandb.enable=true
-```
-
-### Recommended Hyperparameters and Dataset Details (30Hz Control Frequency)
-
-For reliable performance, start with these suggested default hyperparameters:
-
-```bash
-lerobot-train \
-  --dataset.repo_id=YOUR_DATASET \
-  --output_dir=./outputs/mutitask_dit_training \
-  --batch_size=320 \
-  --steps=30000 \
-  --policy.type=multi_task_dit \
-  --policy.device=cuda \
-  --policy.horizon=32 \
-  --policy.n_action_steps=24 \
-  --policy.objective=diffusion \
-  --policy.noise_scheduler_type=DDPM \
-  --policy.num_train_timesteps=100 \
-  --policy.repo_id="HF_USER/multitask-dit-your-robot" \
-  --wandb.enable=true
-```
-
-**Key Parameters:**
-
-- **Batch Size**: 192-320 - If you have access to a GPU that can support this, you will get the best training dynamics
-- **Horizon**: 32 - number of action steps to predict, ~1.0 sec at 30Hz
-- **n_action_steps**: 24 - ~0.8 seconds at 30Hz
-- **Objective**: `diffusion` - start with diffusion and experiment with flow matching if generation quality is poor
-- **Training Steps**: >30k steps recommended for a single task
-
-### Training Configuration Parameters
-
-#### Objective Selection
-
-Choose between diffusion and flow matching:
-
-```bash
-# Diffusion objective (default)
---policy.objective=diffusion \
---policy.noise_scheduler_type=DDPM \  # or "DDIM"
---policy.num_train_timesteps=100 \
---policy.num_inference_steps=10 \  # For faster inference
---policy.beta_schedule=squaredcos_cap_v2 \  # Noise schedule type
---policy.prediction_type=epsilon \  # "epsilon" (predict noise) or "sample" (predict clean)
---policy.clip_sample=true \  # Clip samples during denoising
---policy.clip_sample_range=1.0  # Clipping range [-x, x]
-
-# Flow matching objective
---policy.objective=flow_matching \
---policy.timestep_sampling_strategy=beta \  # or "uniform" | the beta sampling strategy performance appears much better in practice
---policy.num_integration_steps=100 \
---policy.integration_method=euler \  # or "rk4"
---policy.sigma_min=0.0  # Minimum noise in flow interpolation path
-```
-
-#### Transformer Architecture
-
-Adjust model capacity based on dataset size:
-
-```bash
-# Small datasets (< 100 examples)
---policy.num_layers=4 \
---policy.hidden_dim=512 \
---policy.num_heads=8  # should ideally be hidden_dim // 64
-
-# Medium datasets (100-5k examples) - default
---policy.num_layers=6 \
---policy.hidden_dim=512 \
---policy.num_heads=8  # should ideally be hidden_dim // 64
-
-# Large datasets (> 5k examples)
---policy.num_layers=8 \
---policy.hidden_dim=512 \
---policy.num_heads=8   # should ideally be hidden_dim // 64
-```
-
-**Positional Encoding Options:**
-
-The model supports two positional encoding methods for action sequences:
-
-```bash
-# Rotary Position Embedding (RoPE) - default, recommended
---policy.use_rope=true \
---policy.rope_base=10000.0  # Base frequency for RoPE
-
-# Absolute positional encoding
---policy.use_positional_encoding=true  # Disables RoPE when true
-```
-
-**Other Transformer Parameters:**
-
-```bash
---policy.dropout=0.1  # Dropout rate for DiT blocks (0.0-1.0)
---policy.timestep_embed_dim=256  # Timestep embedding dimension
-```
-
-#### Vision Encoder Configuration
-
-```bash
-# Use different CLIP model for more expressivity at the cost of inference time
-# experiment with larger or smaller models depending on the complexity of your tasks and size of dataset
---policy.vision_encoder_name=openai/clip-vit-large-patch14
-
-# Use separate vision encoder per camera
-# This may be useful when cameras have significantly different characteristics, but
-# be wary of increased VRAM footprint.
---policy.use_separate_rgb_encoder_per_camera=true
-
-# Image preprocessing
---policy.image_resize_shape=[XXX,YYY] \ # you may need to resize your images for inference speed ups
---policy.image_crop_shape=[224,224] \
---policy.image_crop_is_random=true  # Random during training, center at inference
-```
-
-#### Text Encoder Configuration
-
-```bash
-# Use different CLIP text encoder model
-# same as vision: experiment with larger or smaller models depending on the
-# complexity of your tasks and size of dataset
---policy.text_encoder_name=openai/clip-vit-large-patch14
-```
-
-#### Learning Rate Configuration
-
-The vision encoder uses a separate learning rate multiplier, where 1/10th is suggested to be the ideal staritng point:
-
-```bash
---policy.optimizer_lr=2e-5 \
---policy.vision_encoder_lr_multiplier=0.1  # Vision encoder LR = 0.1 * optimizer_lr
-```
-
-### Training Tuning Guidelines
-
-#### 1. Flow Matching with Beta Sampling
-
-The original diffusion implementation here is based on the work described in [TRI's LBM paper](https://arxiv.org/abs/2507.05331)
-
-Additionally, we have implemented a flow-matching objective, which is described at a high-level in [Boston Dynamics blog post](https://bostondynamics.com/blog/large-behavior-models-atlas-find-new-footing/).
-
-Consider testing the flow-matching objective and evaluating performance differences for your task:
-
-```bash
---policy.objective=flow_matching \
---policy.timestep_sampling_strategy=beta \
---policy.timestep_sampling_alpha=1.5 \
---policy.timestep_sampling_beta=1.0 \
---policy.timestep_sampling_s=0.999
-```
-
-This hasn't been shown to be a silver bullet across every user case, but it occasionally results in smoother and more consistent actions.
-
-#### 2. Number of Transformer Layers
-
-Match model capacity to your dataset size:
-
-- **Small datasets** (< 100 examples): Reduce to 4 layers
-- **Large datasets** (> 5k examples): Increase to 8 layers
-
-#### 3. `horizon` Tuning
-
-The model can be sensitive to the horizon you choose. Start with around a 1 second horizon based on your control frequency:
-
-- **30 Hz frequency**: `horizon=30`
-- **10 Hz frequency**: `horizon=10`
-
-Then experiment with increasing from there. The horizon determines how far into the future the model predicts actions.
-
-#### 4. `n_action_steps` Sensitivity
-
-The model can also be very sensitive to `n_action_steps`. Start with it being around 0.8 seconds based on your control frequency and tune from there:
-
-- **Lower values**: More reactive but potentially less stable for long-horizon tasks
-- **Higher values**: Better for long-horizon execution but open-loop failures are limited in their recovery
-
-### Inference Tuning
-
-For faster inference, use DDIM with fewer sampling steps:
-
-```bash
---policy.noise_scheduler_type=DDIM \
---policy.num_inference_steps=10
-```
-
-### Resuming Training
-
-To resume training from a checkpoint:
-
-```bash
-lerobot-train \
-  --config_path=./outputs/mutitask_dit_training/checkpoints/last/pretrained_model/train_config.json \
-  --resume=true
-```
-
-The checkpoint directory should contain `model.safetensors` and `config.json` files (saved automatically during training). When resuming, the configuration is loaded from the checkpoint, so you don't need to specify other parameters.
-
-## Common Failure Modes and Debugging
-
-Training these models can be finicky. Here are common failure modes and debugging approaches:
-
-### Idling / No Motion
-
-The model may "collapse" during inference, resulting in static or no motion. This can occur when:
-
-1. **Insufficient training data**: If you only have 20-50 examples, try to roughly double your dataset size. Once you have above 300 examples, if you're still seeing this, the task may be too complex.
-
-2. **Multiple similar tasks**: When your dataset contains multiple similar tasks (e.g., picking up 2 different objects), the model may rely too heavily on language conditioning which might not be rich enough.
-
-**Debugging tips:**
-
-- Increase dataset size (double until you get to over 300 examples)
-- Train for longer, up to 100k steps, even when the loss flatlines
-- Check if the model is receiving proper language instructions or increase diversity of instruction
-
-### Executing the Wrong Task
-
-Sometimes the robot will completely ignore your instruction and perform some other task. This generally only happens if you have trained on multiple tasks.
-
-**Potential causes:**
-
-- Language instruction ambiguity
-- Insufficient task-specific training data
-- Model confusion between similar tasks in the multitask dataset
-
-**Debugging tips:**
-
-- Verify language instruction specificity, especially if descriptions are similar between multiple tasks
-- Check task distribution in your training dataset and add weighting to the failing/ignored task
-- Consider task-specific fine-tuning
-
-### Training Instability
-
-If training loss is unstable or diverging:
-
-- Try adjusting learning rate between `1e-5` and `3e-4`
-- Increase batch size if possible
-- Check that your dataset normalization is correct
-- Verify image preprocessing is working correctly
-
-## Performance Considerations
-
-### GPU Requirements
-
-- **Inference**: At least an RTX 5070 Ti (or equivalent GPU) is recommended for reasonable speed performance
-- **Training**: A GPU with enough VRAM to load batch sizes of >64 is ideal, which will vary depending on the number of image observations, etc
-
-### Batch Size Recommendations
-
-- **Minimum**: 64 (less than this may result in unstable training)
-- **Recommended**: 256-320 (best performance, requires larger GPU)
-

-## Relative Actions
-
-By default, π₀ predicts absolute actions. You can enable **relative actions** so the model predicts offsets relative to the current robot state. This can improve training stability for certain setups.
-
-To use relative actions, first recompute your dataset stats in relative space via the CLI:
-
-```bash
-lerobot-edit-dataset \
-    --repo_id your_dataset \
-    --operation.type recompute_stats \
-    --operation.relative_action true \
-    --operation.chunk_size 50 \
-    --operation.relative_exclude_joints "['gripper']" \
-    --push_to_hub true
-```
-
-Or equivalently in Python:
-
-```python
-from lerobot.datasets import LeRobotDataset, recompute_stats
-
-dataset = LeRobotDataset("your_dataset")
-recompute_stats(dataset, relative_action=True, chunk_size=50, relative_exclude_joints=["gripper"])
-dataset.push_to_hub()
-```
-
-The `chunk_size` should match your policy's `chunk_size` (default 50 for π₀). `relative_exclude_joints` lists joint names that should remain in absolute space (e.g. gripper commands). Use `--push_to_hub true` to upload the updated stats to the Hub.
-
-Then train with relative actions enabled:
-
-```bash
-lerobot-train \
-    --dataset.repo_id=your_dataset \
-    --policy.type=pi0 \
-    --policy.use_relative_actions=true \
-    --policy.relative_exclude_joints='["gripper"]' \

-## Relative Actions
-
-π₀.₅ supports training with **relative actions**, where the model learns relative offsets
-from the current robot state instead of absolute joint positions. This mirrors the
-relative-action transform in OpenPI (`DeltaActions`) and can improve performance.
-
-### How it works
-
-1. **During preprocessing**, absolute actions are converted to relative offsets:
-   `relative = action - state` (for selected joints).
-2. The relative actions are normalized using statistics computed from the relative distribution.
-3. **During postprocessing**, predicted relative actions are converted back to absolute:
-   `absolute = relative + state`.
-
-Joints listed in `relative_exclude_joints` (e.g., gripper) are kept absolute.
-
-### Configuration
-
-| Parameter                 | Type        | Default       | Description                                                      |
-| ------------------------- | ----------- | ------------- | ---------------------------------------------------------------- |
-| `use_relative_actions`    | `bool`      | `False`       | Enable relative-action training                                  |
-| `relative_exclude_joints` | `list[str]` | `["gripper"]` | Joint names to keep absolute (matched by substring)              |
-| `action_feature_names`    | `list[str]` | `None`        | Auto-populated from dataset metadata at runtime by `make_policy` |
-
-### Training example
-
-```bash
-python -m lerobot.scripts.lerobot_train \
-  --policy.type=pi05 \
-  --dataset.repo_id=your_org/your_dataset \
-  --policy.use_relative_actions=true \
-  --policy.relative_exclude_joints='["gripper"]'
-```
-
-When `use_relative_actions=true`, the training script automatically:
-
-- Computes relative action statistics from the dataset (sampled chunk-level relative actions)
-- Replaces the standard action stats with relative stats for normalization
-- Broadcasts these stats across all ranks in distributed training

-# Rename Map and Empty Cameras
-
-When you train, evaluate, or record with a robot policy, your **dataset** or **environment** provides observations under one set of keys (e.g. `observation.images.front`, `observation.images.eagle`), while your **policy** expects another (e.g. `observation.images.image`, `observation.images.image2`). The **rename map** bridges that gap without changing the policy or data source.
-
-> **Scope:** The rename map only renames **observation** keys (images and state). Action keys are not affected.
-
-## Why observation keys don't always match
-
-Policies have a fixed set of **input feature names** baked into their pretrained config. For example:
-
-- [pi0fast-libero](https://huggingface.co/lerobot/pi0fast-libero) expects `observation.images.base_0_rgb` and `observation.images.left_wrist_0_rgb`.
-- [xvla-base](https://huggingface.co/lerobot/xvla-base) expects `observation.images.image`, `observation.images.image2`, and `observation.images.image3`.
-
-Your dataset might use different names entirely (e.g. `observation.images.front`, `observation.images.eagle`, `observation.images.glove`), and your eval environment might use yet another set. Rather than editing the policy config or renaming columns in the dataset, you pass a **rename map**: a JSON dictionary that maps source keys to the keys the policy expects. Renaming happens inside the preprocessor pipeline, so the policy always sees its expected keys.
-
-## Using the rename map
-
-Pass the mapping as a JSON string on the command line. The convention is always:
-
-```
---rename_map='{"source_key": "policy_key", ...}'
-```
-
-where **source_key** is what the dataset or environment provides, and **policy_key** is what the policy expects.
-
-Only listed keys are renamed; everything else passes through unchanged. Order of entries doesn't matter.
-
-Supported policies: **PI0**, **PI05**, **PI0Fast**, **SmolVLA**, and **XVLA**.
-
-### Training
-
-Suppose you fine-tune [lerobot/xvla-base](https://huggingface.co/lerobot/xvla-base) on a dataset with images under `observation.images.front`, `observation.images.eagle`, and `observation.images.glove`. XVLA expects `observation.images.image`, `observation.images.image2`, and `observation.images.image3`:
-
-```bash
-lerobot-train \
-  --dataset.repo_id=YOUR_DATASET \
-  --output_dir=./outputs/xvla_training \
-  --job_name=xvla_training \
-  --policy.path="lerobot/xvla-base" \
-  --policy.repo_id="HF_USER/xvla-your-robot" \
-  --policy.dtype=bfloat16 \
-  --policy.action_mode=auto \
-  --steps=20000 \
-  --policy.device=cuda \
-  --policy.freeze_vision_encoder=false \
-  --policy.freeze_language_encoder=false \
-  --policy.train_policy_transformer=true \
-  --policy.train_soft_prompts=true \
-  --rename_map='{"observation.images.front": "observation.images.image", "observation.images.eagle": "observation.images.image2", "observation.images.glove": "observation.images.image3"}'
-```
-
-### Evaluation
-
-A policy that expects `observation.images.base_0_rgb` and `observation.images.left_wrist_0_rgb` (e.g. [pi0fast-libero](https://huggingface.co/lerobot/pi0fast-libero)), but the LIBERO environment returns `observation.images.image` and `observation.images.image2`:
-
-```bash
-lerobot-eval \
-  --policy.path=lerobot/pi0fast-libero \
-  --env.type=libero \
-  ... \
-  --rename_map='{"observation.images.image": "observation.images.base_0_rgb", "observation.images.image2": "observation.images.left_wrist_0_rgb"}'
-```
-
-### Recording
-
-`lerobot-record` also supports rename maps, nested under the dataset config:
-
-```bash
-lerobot-record \ # When running inference
-  --policy.path="<user>/smolVLA_finetuned" \
-  ... \
-  --dataset.rename_map='{"observation.images.glove2": "observation.images.image"}'
-```
-
-## Alternative: edit the policy config directly
-
-If you always use the same dataset or environment, you can **edit the policy's `config.json`** so its observation keys match your data source. Then no rename map is needed.
-
-The tradeoff: modifying the policy config ties it to one data source. A rename map keeps one policy usable across many datasets and environments.
-
-## Empty cameras: fewer views than the policy expects
-
-Some policies are built for a fixed number of image inputs. If your dataset has fewer cameras, you can set **`empty_cameras`** in the policy config instead of modifying the model architecture.
-
-### How it works
-
-Setting `empty_cameras=N` adds N placeholder image features to the policy config, named:
-
-```
-observation.images.empty_camera_0
-observation.images.empty_camera_1
-...
-```
-
-At runtime, these keys have no corresponding data in the batch. The policy fills them with masked dummy tensors (padded with `-1` for SigLIP-based vision encoders, with a zero attention mask), so the extra image slots are effectively ignored during training and inference.
-
-### Example
-
-XVLA-base has three visual inputs and `empty_cameras=0` by default. Your dataset only has two cameras:
-
-1. Set `--policy.empty_cameras=1`.
-2. The config adds a third key: `observation.images.empty_camera_0`.
-3. Use the rename map for your two real cameras as usual.
-4. The third slot is masked out — no fake images needed in your dataset.
-

-
-## Available tasks
-
-RoboCasa365 organizes its 365 tasks into two families and three upstream benchmark groups that LeRobot exposes as first-class `--env.task` shortcuts:
-
-| Family    | Tasks | Description                                                                     |
-| --------- | ----- | ------------------------------------------------------------------------------- |
-| Atomic    | ~65   | Single-skill tasks: pick-and-place, door/drawer manipulation, appliance control |
-| Composite | ~300  | Multi-step tasks across 60+ categories: cooking, cleaning, organizing, etc.     |
-
-**Atomic task examples:** `CloseFridge`, `OpenDrawer`, `OpenCabinet`, `TurnOnMicrowave`, `TurnOffStove`, `NavigateKitchen`, `PickPlaceCounterToStove`.
-
-**Composite task categories:** baking, boiling, brewing, chopping, clearing table, defrosting food, loading dishwasher, making tea, microwaving food, washing dishes, and more.
-
-`--env.task` accepts three forms:
-
-- a single task name (`CloseFridge`)
-- a comma-separated list (`CloseFridge,OpenBlenderLid,PickPlaceCoffee`)
-- a benchmark-group shortcut — `atomic_seen`, `composite_seen`, `composite_unseen`, `pretrain50`, `pretrain100`, `pretrain200`, `pretrain300` — which auto-expands to the upstream task list and auto-sets the dataset `split` (`target` or `pretrain`).
-
-## Installation
-
-RoboCasa and its dependency `robosuite` are not published on PyPI, and RoboCasa's own `setup.py` hardcodes `lerobot==0.3.3`, which conflicts with this repo's `lerobot`. LeRobot therefore does **not** expose a `robocasa` extra — install the two packages manually as editable clones (using `--no-deps` on `robocasa` to skip its shadowed `lerobot` pin):
-
-```bash
-# After following the standard LeRobot installation instructions.
-
-git clone https://github.com/robocasa/robocasa.git ~/robocasa
-git clone https://github.com/ARISE-Initiative/robosuite.git ~/robosuite
-pip install -e ~/robocasa --no-deps
-pip install -e ~/robosuite
-
-# Robocasa's runtime deps (the ones its setup.py would have pulled, minus
-# the bad lerobot pin).
-pip install numpy numba scipy mujoco pygame Pillow opencv-python \
-            pyyaml pynput tqdm termcolor imageio h5py lxml hidapi \
-            tianshou gymnasium
-
-python -m robocasa.scripts.setup_macros
-# Lightweight assets (lightwheel object meshes + textures). Enough for
-# the default env out of the box.
-python -m robocasa.scripts.download_kitchen_assets \
-  --type tex tex_generative fixtures_lw objs_lw
-# Optional: full objaverse/aigen registries (~30GB) for richer object
-# variety. Enable at eval time via --env.obj_registries (see below).
-# python -m robocasa.scripts.download_kitchen_assets --type objs_objaverse
-```
-
-<Tip>
-RoboCasa requires MuJoCo. Set the rendering backend before training or evaluation:
-
-```bash
-export MUJOCO_GL=egl  # for headless servers (HPC, cloud)
-```
-
-</Tip>
-
-### Object registries

-By default the env samples objects only from the `lightwheel` registry (what `--type objs_lw` ships), which avoids a `Probabilities contain NaN` crash when the objaverse / aigen packs aren't on disk. If you've downloaded the full asset set, enable the full registry at runtime:
-
-```bash
---env.obj_registries='[objaverse,lightwheel]'
-```
-
-## Evaluation
-
-All eval snippets below mirror the CI command (see `.github/workflows/benchmark_tests.yml`). The `--rename_map` argument maps RoboCasa's native camera keys (`robot0_agentview_left` / `robot0_eye_in_hand` / `robot0_agentview_right`) onto the three-camera (`camera1` / `camera2` / `camera3`) input layout the released `smolvla_robocasa` policy was trained on.
-
-### Single-task evaluation (recommended for quick iteration)
-
-```bash
-lerobot-eval \
-  --policy.path=lerobot/smolvla_robocasa \
-  --env.type=robocasa \
-  --env.task=CloseFridge \
-  --eval.batch_size=1 \
-  --eval.n_episodes=20 \
-  --eval.use_async_envs=false \
-  --policy.device=cuda \
-  '--rename_map={"observation.images.robot0_agentview_left": "observation.images.camera1", "observation.images.robot0_eye_in_hand": "observation.images.camera2", "observation.images.robot0_agentview_right": "observation.images.camera3"}'
-```
-
-### Multi-task evaluation
-
-Pass a comma-separated list of tasks:
-
-```bash
-lerobot-eval \
-  --policy.path=lerobot/smolvla_robocasa \
-  --env.type=robocasa \
-  --env.task=CloseFridge,OpenCabinet,OpenDrawer,TurnOnMicrowave,TurnOffStove \
-  --eval.batch_size=1 \
-  --eval.n_episodes=20 \
-  --eval.use_async_envs=false \
-  --policy.device=cuda \
-  '--rename_map={"observation.images.robot0_agentview_left": "observation.images.camera1", "observation.images.robot0_eye_in_hand": "observation.images.camera2", "observation.images.robot0_agentview_right": "observation.images.camera3"}'
-```
-
-### Benchmark-group evaluation
-
-Run an entire upstream group (e.g. all 18 `atomic_seen` tasks with `split=target`):
-
-```bash
-lerobot-eval \
-  --policy.path=lerobot/smolvla_robocasa \
-  --env.type=robocasa \
-  --env.task=atomic_seen \
-  --eval.batch_size=1 \
-  --eval.n_episodes=20 \
-  --eval.use_async_envs=false \
-  --policy.device=cuda \
-  '--rename_map={"observation.images.robot0_agentview_left": "observation.images.camera1", "observation.images.robot0_eye_in_hand": "observation.images.camera2", "observation.images.robot0_agentview_right": "observation.images.camera3"}'
-```
-
-### Recommended evaluation episodes
-
-**20 episodes per task** for reproducible benchmarking. Matches the protocol used in published results.
-
-## Policy inputs and outputs
-
-**Observations** (raw RoboCasa camera names are preserved verbatim):
-
-- `observation.state` — 16-dim proprioceptive state (base position, base quaternion, relative end-effector position, relative end-effector quaternion, gripper qpos)
-- `observation.images.robot0_agentview_left` — left agent view, 256×256 HWC uint8
-- `observation.images.robot0_eye_in_hand` — wrist camera view, 256×256 HWC uint8
-- `observation.images.robot0_agentview_right` — right agent view, 256×256 HWC uint8
-
-**Actions:**
-
-- Continuous control in `Box(-1, 1, shape=(12,))` — base motion (4D) + control mode (1D) + end-effector position (3D) + end-effector rotation (3D) + gripper (1D).
-
-## Training
-
-### Single-task example
-
-A ready-to-use single-task dataset is on the Hub:
-[`pepijn223/robocasa_CloseFridge`](https://huggingface.co/datasets/pepijn223/robocasa_CloseFridge).
-
-Fine-tune a SmolVLA base on `CloseFridge`:
-
-```bash
-lerobot-train \
-  --policy.type=smolvla \
-  --policy.repo_id=${HF_USER}/smolvla_robocasa_CloseFridge \
-  --policy.load_vlm_weights=true \

-  --eval_freq=5000 \
-  --eval.batch_size=1 \
-  --eval.n_episodes=5 \
-  --save_freq=10000
-```
-
-Evaluate the resulting checkpoint:
-
-```bash
-lerobot-eval \
-  --policy.path=${HF_USER}/smolvla_robocasa_CloseFridge \
-  --env.type=robocasa \
-  --env.task=CloseFridge \
-  --eval.batch_size=1 \

-
-## Reproducing published results
-
-The released checkpoint [`lerobot/smolvla_robocasa`](https://huggingface.co/lerobot/smolvla_robocasa) is evaluated with the commands in the [Evaluation](#evaluation) section. CI runs a 10-atomic-task smoke eval (one episode each) on every PR touching the benchmark, picking fixture-centric tasks that don't require the objaverse asset pack.

-# RoboCerebra
-
-[RoboCerebra](https://robocerebra-project.github.io/) is a long-horizon manipulation benchmark that evaluates **high-level reasoning, planning, and memory** in VLAs. Episodes chain multiple sub-goals with language-grounded intermediate instructions, built on top of LIBERO's simulator stack (MuJoCo + robosuite, Franka Panda 7-DOF).
-
-- Paper: [RoboCerebra: A Large-scale Benchmark for Long-horizon Robotic Manipulation Evaluation](https://arxiv.org/abs/2506.06677)
-- Project website: [robocerebra-project.github.io](https://robocerebra-project.github.io/)
-- Dataset: [`lerobot/robocerebra_unified`](https://huggingface.co/datasets/lerobot/robocerebra_unified) — LeRobot v3.0, 6,660 episodes / 571,116 frames at 20 fps, 1,728 language-grounded sub-tasks.
-- Pretrained policy: [`lerobot/smolvla_robocerebra`](https://huggingface.co/lerobot/smolvla_robocerebra)
-
-## Available tasks
-
-RoboCerebra reuses LIBERO's simulator, so evaluation runs against the LIBERO `libero_10` long-horizon suite:
-
-| Suite     | CLI name    | Tasks | Description                                                   |
-| --------- | ----------- | ----- | ------------------------------------------------------------- |
-| LIBERO-10 | `libero_10` | 10    | Long-horizon kitchen/living room tasks chaining 3–6 sub-goals |
-
-Each RoboCerebra episode in the dataset is segmented into multiple sub-tasks with natural-language instructions, which the unified dataset exposes as independent supervision signals.
-
-## Installation
-
-RoboCerebra piggybacks on LIBERO, so the `libero` extra is all you need:
-
-```bash
-pip install -e ".[libero]"
-```
-
-<Tip>
-RoboCerebra requires Linux (MuJoCo / robosuite). Set the rendering backend before training or evaluation:
-
-```bash
-export MUJOCO_GL=egl  # for headless servers (HPC, cloud)
-```
-
-</Tip>
-
-## Evaluation
-
-RoboCerebra eval runs against LIBERO's `libero_10` suite with RoboCerebra's camera naming (`image` + `wrist_image`) and an extra empty-camera slot so a three-view-trained policy receives the expected input layout:
-
-```bash
-lerobot-eval \
-  --policy.path=lerobot/smolvla_robocerebra \
-  --env.type=libero \
-  --env.task=libero_10 \
-  --env.fps=20 \
-  --env.obs_type=pixels_agent_pos \
-  --env.observation_height=256 \
-  --env.observation_width=256 \
-  '--env.camera_name_mapping={"agentview_image": "image", "robot0_eye_in_hand_image": "wrist_image"}' \
-  --eval.batch_size=1 \
-  --eval.n_episodes=10 \
-  --eval.use_async_envs=false \
-  --policy.device=cuda \
-  '--rename_map={"observation.images.image": "observation.images.camera1", "observation.images.wrist_image": "observation.images.camera2"}' \
-  --policy.empty_cameras=1
-```
-
-### Recommended evaluation episodes
-
-**10 episodes per task** across the `libero_10` suite (100 total) for reproducible benchmarking. Matches the protocol used in the RoboCerebra paper.
-
-## Policy inputs and outputs
-
-**Observations:**
-
-- `observation.state` — 8-dim proprioceptive state (7 joint positions + gripper)
-- `observation.images.image` — third-person view, 256×256 HWC uint8
-- `observation.images.wrist_image` — wrist-mounted camera view, 256×256 HWC uint8
-
-**Actions:**
-
-- Continuous control in `Box(-1, 1, shape=(7,))` — end-effector delta (6D) + gripper (1D)
-
-## Training
-
-The unified dataset at [`lerobot/robocerebra_unified`](https://huggingface.co/datasets/lerobot/robocerebra_unified) exposes two RGB streams and language-grounded sub-task annotations:
-
-| Feature                          | Shape         | Description          |
-| -------------------------------- | ------------- | -------------------- |

-| **Imitation** (procedural memory) | MoveCube, InsertPeg, PatternLock, RouteStick                  |
-
-## Installation
-
-> RoboMME requires **Linux** (ManiSkill/SAPIEN uses Vulkan rendering). Docker is recommended to isolate dependency conflicts.
-
-### Native (Linux)
-
-```bash
-pip install --override <(printf 'gymnasium==0.29.1\nnumpy==1.26.4\n') \
-  -e '.[smolvla,av-dep]' \
-  'robomme @ git+https://github.com/RoboMME/robomme_benchmark.git@main'
-```
-
-> **Dependency note**: `mani-skill` (pulled by `robomme`) pins `gymnasium==0.29.1` and `numpy<2.0.0`, which conflict with lerobot's base `numpy>=2.0.0`. That's why `robomme` is not a pyproject extra — use the override install above, or the Docker approach below to avoid conflicts entirely.
-
-### Docker (recommended)
-
-```bash
-# Build base image first (from repo root)
-docker build -f docker/Dockerfile.eval-base -t lerobot-eval-base .
-
-# Build RoboMME eval image (applies gymnasium + numpy pin overrides)
-docker build -f docker/Dockerfile.benchmark.robomme -t lerobot-robomme .
-```
-
-The `docker/Dockerfile.benchmark.robomme` image overrides `gymnasium==0.29.1` and `numpy==1.26.4` after lerobot's install. Both versions are runtime-safe for lerobot's actual API usage.
-
-## Running Evaluation
-
-### Default (single task, single episode)
-
-```bash
-lerobot-eval \
-    --policy.path=<your_policy_repo> \
-    --env.type=robomme \
-    --env.task=PickXtimes \
-    --env.dataset_split=test \
-    --env.task_ids=[0] \
-    --eval.batch_size=1 \
-    --eval.n_episodes=1
-```
-
-### Multi-task evaluation
-
-Evaluate multiple tasks in one run by comma-separating task names. Use `task_ids` to control which episodes are evaluated per task. Recommended: 50 episodes per task for the test split.
-
-```bash
-lerobot-eval \
-    --policy.path=<your_policy_repo> \
-    --env.type=robomme \
-    --env.task=PickXtimes,BinFill,StopCube,MoveCube,InsertPeg \
-    --env.dataset_split=test \
-    --env.task_ids=[0,1,2,3,4,5,6,7,8,9] \
-    --eval.batch_size=1 \
-    --eval.n_episodes=50
-```
-
-### Key CLI options for `env.type=robomme`
-
-| Option               | Default       | Description                                        |
-| -------------------- | ------------- | -------------------------------------------------- |
-| `env.task`           | `PickXtimes`  | Any of the 16 task names above (comma-separated)   |
-| `env.dataset_split`  | `test`        | `train`, `val`, or `test`                          |
-| `env.action_space`   | `joint_angle` | `joint_angle` (8-D) or `ee_pose` (7-D)             |
-| `env.episode_length` | `300`         | Max steps per episode                              |
-| `env.task_ids`       | `null`        | List of episode indices to evaluate (null = `[0]`) |
-
-## Dataset
-
-The dataset [`lerobot/robomme`](https://huggingface.co/datasets/lerobot/robomme) is in **LeRobot v3.0 format** and can be loaded directly:
-
-```python
-from lerobot.datasets.lerobot_dataset import LeRobotDataset
-
-dataset = LeRobotDataset("lerobot/robomme")
-```
-
-### Dataset features
-
-| Feature            | Shape         | Description                     |
-| ------------------ | ------------- | ------------------------------- |
-| `image`            | (256, 256, 3) | Front camera RGB                |
-| `wrist_image`      | (256, 256, 3) | Wrist camera RGB                |
-| `actions`          | (8,)          | Joint angles + gripper          |
-| `state`            | (8,)          | Joint positions + gripper state |
-| `simple_subgoal`   | str           | High-level language annotation  |
-| `grounded_subgoal` | str           | Grounded language annotation    |
-| `episode_index`    | int           | Episode ID                      |
-| `frame_index`      | int           | Frame within episode            |
-
-### Feature key alignment (training)
-
-The env wrapper exposes `pixels/image` and `pixels/wrist_image` as observation keys. The `features_map` in `RoboMMEEnv` maps these to `observation.images.image` and `observation.images.wrist_image` for the policy. State is exposed as `agent_pos` and maps to `observation.state`.
-
-The dataset's `image` and `wrist_image` columns already align with the policy input keys, so no renaming is needed when fine-tuning.
-
-## Action Spaces
-
-| Type          | Dim | Description                                               |
-| ------------- | --- | --------------------------------------------------------- |
-| `joint_angle` | 8   | 7 joint angles + 1 gripper (−1 closed, +1 open, absolute) |
-| `ee_pose`     | 7   | xyz + roll/pitch/yaw + gripper                            |
-
-Set via `--env.action_space=joint_angle` (default) or `--env.action_space=ee_pose`.
-
-## Platform Notes
-
-- **Linux only**: ManiSkill requires SAPIEN/Vulkan. macOS and Windows are not supported.
-- **GPU recommended**: Rendering is CPU-capable but slow; CUDA + Vulkan gives full speed.
-- **gymnasium / numpy conflict**: See installation note above. Docker image handles this automatically.
-- **ManiSkill fork**: `robomme` depends on a specific ManiSkill fork (`YinpeiDai/ManiSkill`), pulled in automatically via the `robomme` package.

-## Available tasks
-
-RoboTwin 2.0 ships 50 dual-arm manipulation tasks in its upstream `envs/` directory. The canonical list is the `ROBOTWIN_TASKS` tuple in `src/lerobot/envs/robotwin.py`, mirrored verbatim from the upstream repo. Example tasks:
-
-| Task                     | CLI name                 | Category          |
-| ------------------------ | ------------------------ | ----------------- |
-| Beat block with hammer   | `beat_block_hammer`      | Tool use          |
-| Click bell / alarm clock | `click_bell`             | Precision press   |
-| Stack blocks (2 / 3)     | `stack_blocks_two/three` | Stacking          |
-| Stack bowls (2 / 3)      | `stack_bowls_two/three`  | Stacking          |
-| Handover block / mic     | `handover_block`         | Bimanual coord.   |
-| Lift pot                 | `lift_pot`               | Bimanual lift     |
-| Shake bottle             | `shake_bottle`           | Continuous motion |
-| Turn switch              | `turn_switch`            | Articulated obj   |
-| Stamp seal               | `stamp_seal`             | Precision place   |
-| Scan object              | `scan_object`            | Mobile manip.     |
-
-Pass a comma-separated list to `--env.task` to run multiple tasks in a single eval sweep.
-
-<Tip warning={true}>
-  `open_laptop` is currently broken upstream (its `check_success()` uses
-  `self.arm_tag`, which is only set inside the scripted-expert `play_once()`
-  path and therefore unavailable during normal policy eval). Avoid it until the
-  upstream bug is fixed, or patch the task to default `self.arm_tag = "left"` in
-  `load_actors()`.
-</Tip>
-
-## Dataset
-
-The RoboTwin 2.0 dataset is available in **LeRobot v3.0 format** on the Hugging Face Hub:
-
-```
-lerobot/robotwin_unified
-```
-
-It contains over 100,000 pre-collected trajectories across all 50 tasks (79.6 GB, Apache 2.0 license). No format conversion is needed — it is already in the correct LeRobot v3.0 schema with video observations and action labels.
-
-You can load it directly with the HF Datasets library:
-
-```python
-from datasets import load_dataset
-
-ds = load_dataset("lerobot/robotwin_unified", split="train")
-```
-
-## Installation
-
-RoboTwin 2.0 requires **Linux** with an NVIDIA GPU (CUDA 12.1 recommended). Installation takes approximately 20 minutes.
-
-### 1. Create a conda environment
-
-```bash
-conda create -n robotwin python=3.10 -y
-conda activate robotwin
-```
-
-### 2. Install LeRobot
-
-```bash
-git clone https://github.com/huggingface/lerobot.git
-cd lerobot
-pip install -e "."
-```
-
-### 3. Install RoboTwin 2.0
-
-```bash
-git clone https://github.com/RoboTwin-Platform/RoboTwin.git
-cd RoboTwin
-bash script/_install.sh
-bash script/_download_assets.sh
-```
-
-The install script handles all Python dependencies including SAPIEN, CuRobo, mplib, and pytorch3d.
-
-<Tip warning={true}>
-If the automated install fails, install manually:
-
-```bash
-pip install -r requirements.txt
-pip install "git+https://github.com/facebookresearch/pytorch3d.git@stable"
-cd envs && git clone https://github.com/NVlabs/curobo.git && cd curobo
-pip install -e . --no-build-isolation
-```
-
-Then apply the required mplib fix: in `mplib/planner.py` line 807, remove `or collide` from the conditional.
-

-### 4. Add RoboTwin to PYTHONPATH
-
-The RoboTwin task modules must be importable by LeRobot. From within the `RoboTwin/` directory:
-
-```bash
-export PYTHONPATH="${PYTHONPATH}:$(pwd)"
-```
-
-Add this to your shell profile to make it permanent.
-
-## Evaluation
-
-### Standard evaluation (recommended)
-
-Evaluate a policy on a single task with the official protocol (100 episodes):
-
-```bash
-lerobot-eval \
-  --policy.path="your-hf-policy-id" \
-  --env.type=robotwin \
-  --env.task=beat_block_hammer \
-  --eval.batch_size=1 \
-  --eval.n_episodes=100
-```
-
-### Single-task quick check
-
-```bash
-lerobot-eval \
-  --policy.path="your-hf-policy-id" \
-  --env.type=robotwin \
-  --env.task=beat_block_hammer \
-  --eval.batch_size=1 \
-  --eval.n_episodes=5
-```
-
-### Multi-task sweep
-
-Evaluate on several tasks in one run:
-
-```bash
-lerobot-eval \
-  --policy.path="your-hf-policy-id" \
-  --env.type=robotwin \
-  --env.task=beat_block_hammer,click_bell,handover_block,stack_blocks_two \
-  --eval.batch_size=1 \
-  --eval.n_episodes=100

-# Tools
-
-LeRobot v3.1 supports **tool calls** in policies — assistant messages can
-emit structured invocations like `say(text="OK, starting now")` that the
-runtime dispatches to a real implementation (TTS, controller, logger, …).
-
-This page covers:
-
-1. Where the tool catalog lives (PR 1).
-2. How the annotation pipeline produces tool-call atoms (PR 2).
-3. How to add your own tool (PR 3).
-
-## Where tools are declared
-
-Two layers.
-
-**The catalog** — a list of OpenAI-style function schemas — lives at
-`meta/info.json["tools"]` on each dataset. Example:
-
-```json
-{
-  "features": { "...": "..." },
-  "tools": [
-    {
-      "type": "function",
-      "function": {
-        "name": "say",
-        "description": "Speak a short utterance to the user via the TTS executor.",
-        "parameters": {
-          "type": "object",
-          "properties": {
-            "text": { "type": "string", "description": "The verbatim text to speak." }
-          },
-          "required": ["text"]
-        }
-      }
-    }
-  ]
-}
-```
-
-Read it via the dataset metadata accessor:
-
-```python
-from lerobot.datasets.dataset_metadata import LeRobotDatasetMetadata
-
-meta = LeRobotDatasetMetadata(repo_id="pepijn/super_poulain_final_annotations")
-tools = meta.tools     # list[dict] — OpenAI tool schemas
-```
-
-If the dataset's `info.json` doesn't declare any tools, `meta.tools`
-returns `DEFAULT_TOOLS` from `lerobot.datasets.language` — currently a
-single-entry list with the canonical `say` schema. So unannotated
-datasets and chat-template consumers keep working without any
-configuration:
-
-```python
-prompt_str = tokenizer.apply_chat_template(
-    sample["messages"],
-    tools=meta.tools,                 # works either way
-    add_generation_prompt=False,
-    tokenize=False,
-)
-```
-
-**The implementations** — runnable Python — live under
-`src/lerobot/tools/`, one file per tool. The `say` implementation
-arrives in PR 3 and wraps Kyutai's pocket-tts model.
-
-## Per-row tool *invocations*
-
-The catalog above describes *what can be called*. The actual *call* — the
-function name plus the argument values — is stored per-row, on the
-assistant atoms in `language_events`:
-
-```python
-{
-  "role": "assistant",
-  "content": null,
-  "style": null,
-  "timestamp": 12.4,
-  "camera": null,
-  "tool_calls": [
-    { "type": "function",
-      "function": { "name": "say", "arguments": { "text": "On it." } } }
-  ]
-}
-```
-
-Recipes splice these into rendered messages via `tool_calls_from`:
-
-```yaml
-user_interjection_response:
-  bindings:
-    speech: "emitted_at(t, role=assistant, tool_name=say)"
-  messages:
-    - { role: user,      content: "${task}",         stream: high_level }
-    - { role: assistant, content: "${current_plan}", stream: high_level,
-        target: true, tool_calls_from: speech }
-```
-
-The model's training target is one assistant turn that carries both the
-plan text *and* the `say` tool call. At inference, the runtime parses
-the generated text back into structured `tool_calls` and dispatches to
-the matching implementation.
-
-## How to add your own tool
-
-Three steps. Concrete example: a `record_observation` tool the policy
-can call to capture an extra observation outside the regular control
-loop.
-
-### Step 1 — declare the schema
-
-Add an entry under `meta/info.json["tools"]`. Either edit the file
-directly on disk *before* running the annotation pipeline (it'll be
-preserved) or hand it to `lerobot-annotate` via a config flag (PR 2 —
-exact CLI lands with the pipeline change).
-
-```json
-{
-  "tools": [
-    { "type": "function", "function": { "name": "say", "...": "..." } },
-    {
-      "type": "function",
-      "function": {
-        "name": "record_observation",
-        "description": "Capture a high-resolution still image for the user.",
-        "parameters": {
-          "type": "object",
-          "properties": {
-            "label": { "type": "string", "description": "Short label for the saved image." }
-          },
-          "required": ["label"]
-        }
-      }
-    }
-  ]
-}
-```
-
-The schema follows OpenAI's function-calling convention exactly, so the
-chat template can render it natively.
-
-### Step 2 — implement the call
-
-Create `src/lerobot/tools/record_observation.py`:
-
-```python
-from .base import Tool
-from typing import Any
-
-RECORD_OBSERVATION_SCHEMA: dict[str, Any] = { "...": "..." }   # mirrors the JSON above
-
-
-class RecordObservationTool:
-    name = "record_observation"
-    schema = RECORD_OBSERVATION_SCHEMA
-
-    def __init__(self, schema: dict | None = None, output_dir: str = "."):
-        self.output_dir = output_dir
-
-    def call(self, arguments: dict) -> str:
-        label = arguments["label"]
-        # ... save the latest camera frame to <output_dir>/<label>.png ...
-        return f"saved {label}.png"
-```
-
-One file per tool keeps dependencies isolated — `record_observation`
-might pull `pillow`, while `say` (PR 3) pulls `pocket-tts`. Users
-installing only the tools they need avoid heavy transitive deps.
-
-### Step 3 — register it
-
-Add to `src/lerobot/tools/registry.py` (PR 3):
-
-```python
-from .record_observation import RecordObservationTool
-
-TOOL_REGISTRY["record_observation"] = RecordObservationTool
-```
-
-That's it. At runtime `get_tools(meta)` looks up each schema in
-`meta.tools`, instantiates the matching registered class, and returns
-a name → instance dict the dispatcher can route into.
-
-## Where this fits in the three-PR stack
-
-| Layer | PR | What lands |
-|---|---|---|
-| Catalog storage in `meta/info.json` + `meta.tools` accessor | PR 1 | This page; `SAY_TOOL_SCHEMA`, `DEFAULT_TOOLS` constants in `lerobot.datasets.language`; `LeRobotDatasetMetadata.tools` property |
-| Annotation pipeline writes `tools` to meta after a run; honors anything users pre-populated | PR 2 | `lerobot-annotate` ensures `meta/info.json["tools"]` includes the canonical `say` and merges any user-declared tools |
-| Runnable implementations under `src/lerobot/tools/`; runtime dispatcher; `say.py` wired to Kyutai's pocket-tts | PR 3 | One file per tool; `Tool` protocol; `TOOL_REGISTRY`; optional `[tools]` extra in `pyproject.toml` |
-
-If you want to use a tool *without* writing an implementation (e.g. for
-training-time chat-template formatting only), step 1 alone is enough —
-the model still learns to *generate* the call. Steps 2 and 3 are only
-needed to actually *execute* it at inference.

-# VLABench
-
-[VLABench](https://github.com/OpenMOSS/VLABench) is a large-scale benchmark for **language-conditioned robotic manipulation with long-horizon reasoning**. The upstream suite covers 100 task categories across 2,000+ objects and evaluates six dimensions of robot intelligence: mesh & texture understanding, spatial reasoning, world-knowledge transfer, semantic instruction comprehension, physical-law understanding, and long-horizon planning. Built on MuJoCo / dm_control with a Franka Panda 7-DOF arm. LeRobot exposes **43 of these tasks** through `--env.task` (21 primitives + 22 composites, see [Available tasks](#available-tasks) below).

-## Available tasks
-
-VLABench ships two task suites covering **43 task categories** in LeRobot's `--env.task` surface:
-
-| Suite     | CLI name    | Tasks | Description                                                      |
-| --------- | ----------- | ----- | ---------------------------------------------------------------- |
-| Primitive | `primitive` | 21    | Single / few-skill combinations (select, insert, physics QA)     |
-| Composite | `composite` | 22    | Multi-step reasoning and long-horizon planning (cook, rearrange) |
-
-**Primitive tasks:** `select_fruit`, `select_toy`, `select_chemistry_tube`, `add_condiment`, `select_book`, `select_painting`, `select_drink`, `insert_flower`, `select_billiards`, `select_ingredient`, `select_mahjong`, `select_poker`, and physical-reasoning tasks (`density_qa`, `friction_qa`, `magnetism_qa`, `reflection_qa`, `simple_cuestick_usage`, `simple_seesaw_usage`, `sound_speed_qa`, `thermal_expansion_qa`, `weight_qa`).
-
-**Composite tasks:** `cluster_billiards`, `cluster_book`, `cluster_drink`, `cluster_toy`, `cook_dishes`, `cool_drink`, `find_unseen_object`, `get_coffee`, `hammer_nail`, `heat_food`, `make_juice`, `play_mahjong`, `play_math_game`, `play_poker`, `play_snooker`, `rearrange_book`, `rearrange_chemistry_tube`, `set_dining_table`, `set_study_table`, `store_food`, `take_chemistry_experiment`, `use_seesaw_complex`.
-
-`--env.task` accepts three forms:
-
-- a single task name (`select_fruit`)
-- a comma-separated list (`select_fruit,heat_food`)
-- a suite shortcut (`primitive`, `composite`, or `primitive,composite`)
-
-## Installation
-
-VLABench is **not on PyPI** — its only distribution is the [OpenMOSS/VLABench](https://github.com/OpenMOSS/VLABench) GitHub repo — so LeRobot does not expose a `vlabench` extra. Install it manually as an editable clone, alongside the MuJoCo / dm_control pins VLABench needs, then fetch the mesh assets:
-
-```bash
-# After following the standard LeRobot installation instructions.
-
-git clone https://github.com/OpenMOSS/VLABench.git ~/VLABench
-git clone https://github.com/motion-planning/rrt-algorithms.git ~/rrt-algorithms
-pip install -e ~/VLABench -e ~/rrt-algorithms
-pip install "mujoco==3.2.2" "dm-control==1.0.22" \
-            open3d colorlog scikit-learn openai gdown
-
-python ~/VLABench/scripts/download_assets.py
-```
-
-<Tip>
-VLABench requires Linux (`sys_platform == 'linux'`) and Python 3.10+. Set the MuJoCo rendering backend before running:
-
-```bash
-export MUJOCO_GL=egl  # for headless servers (HPC, cloud)
-```
-
-</Tip>
-
-## Evaluation
-
-All eval snippets below mirror the command CI runs (see `.github/workflows/benchmark_tests.yml`). The `--rename_map` argument maps VLABench's `image` / `second_image` / `wrist_image` camera keys onto the three-camera (`camera1` / `camera2` / `camera3`) input layout the released `smolvla_vlabench` policy was trained on.
-
-### Single-task evaluation (recommended for quick iteration)
-
-```bash
-lerobot-eval \
-  --policy.path=lerobot/smolvla_vlabench \
-  --env.type=vlabench \
-  --env.task=select_fruit \
-  --eval.batch_size=1 \
-  --eval.n_episodes=10 \
-  --eval.use_async_envs=false \
-  --policy.device=cuda \
-  '--rename_map={"observation.images.image": "observation.images.camera1", "observation.images.second_image": "observation.images.camera2", "observation.images.wrist_image": "observation.images.camera3"}'
-```
-
-### Multi-task evaluation
-
-Pass a comma-separated list of tasks:
-
-```bash
-lerobot-eval \
-  --policy.path=lerobot/smolvla_vlabench \
-  --env.type=vlabench \
-  --env.task=select_fruit,select_toy,add_condiment,heat_food \
-  --eval.batch_size=1 \
-  --eval.n_episodes=10 \
-  --eval.use_async_envs=false \
-  --policy.device=cuda \
-  '--rename_map={"observation.images.image": "observation.images.camera1", "observation.images.second_image": "observation.images.camera2", "observation.images.wrist_image": "observation.images.camera3"}'
-```
-
-### Suite-wide evaluation
-
-Run an entire suite (all 21 primitives or all 22 composites):
-
-```bash
-lerobot-eval \
-  --policy.path=lerobot/smolvla_vlabench \
-  --env.type=vlabench \
-  --env.task=primitive \
-  --eval.batch_size=1 \
-  --eval.n_episodes=10 \
-  --eval.use_async_envs=false \
-  --policy.device=cuda \
-  --env.max_parallel_tasks=1 \
-  '--rename_map={"observation.images.image": "observation.images.camera1", "observation.images.second_image": "observation.images.camera2", "observation.images.wrist_image": "observation.images.camera3"}'
-```
-
-Or both suites:
-
-```bash
-lerobot-eval \
-  --policy.path=lerobot/smolvla_vlabench \
-  --env.type=vlabench \
-  --env.task=primitive,composite \
-  --eval.batch_size=1 \
-  --eval.n_episodes=10 \
-  --eval.use_async_envs=false \
-  --policy.device=cuda \
-  --env.max_parallel_tasks=1 \
-  '--rename_map={"observation.images.image": "observation.images.camera1", "observation.images.second_image": "observation.images.camera2", "observation.images.wrist_image": "observation.images.camera3"}'
-```
-
-### Recommended evaluation episodes
-
-**10 episodes per task** for reproducible benchmarking (210 total for the full primitive suite, 220 for composite). Matches the protocol in the VLABench paper.
-
-## Policy inputs and outputs
-
-**Observations:**
-
-- `observation.state` — 7-dim end-effector state (position xyz + Euler xyz + gripper)
-- `observation.images.image` — front camera, 480×480 HWC uint8
-- `observation.images.second_image` — second camera, 480×480 HWC uint8
-- `observation.images.wrist_image` — wrist camera, 480×480 HWC uint8
-
-**Actions:**
-
-- Continuous control in `Box(-1, 1, shape=(7,))` — 3D position + 3D Euler orientation + 1D gripper.
-
-## Training
-
-### Datasets
-
-Pre-collected VLABench datasets in LeRobot format on the Hub:
-
-- [`VLABench/vlabench_primitive_ft_lerobot_video`](https://huggingface.co/datasets/VLABench/vlabench_primitive_ft_lerobot_video) — 5,000 episodes, 128 tasks, 480×480 images.
-- [`VLABench/vlabench_composite_ft_lerobot_video`](https://huggingface.co/datasets/VLABench/vlabench_composite_ft_lerobot_video) — 5,977 episodes, 167 tasks, 224×224 images.
-
-### Example training command
-
-Fine-tune a SmolVLA base on the primitive suite:
-
-```bash
-lerobot-train \
-  --policy.type=smolvla \
-  --policy.repo_id=${HF_USER}/smolvla_vlabench_primitive \
-  --policy.load_vlm_weights=true \
-  --policy.push_to_hub=true \
-  --dataset.repo_id=VLABench/vlabench_primitive_ft_lerobot_video \
-  --env.type=vlabench \
-  --env.task=select_fruit \
-  --output_dir=./outputs/smolvla_vlabench_primitive \
-  --steps=100000 \
-  --batch_size=4 \
-  --eval_freq=5000 \
-  --eval.batch_size=1 \
-  --eval.n_episodes=1 \
-  --save_freq=10000
-```
-
-## Reproducing published results
-
-The released checkpoint [`lerobot/smolvla_vlabench`](https://huggingface.co/lerobot/smolvla_vlabench) was trained on the primitive-suite dataset above and is evaluated with the [Single-task](#single-task-evaluation-recommended-for-quick-iteration) / [Suite-wide](#suite-wide-evaluation) commands. CI runs a 10-primitive-task smoke eval (one episode each) on every PR touching the benchmark.
