dfdc48a7f1 fix(datasets): bound VideoDecoderCache to prevent OOM on large datasets (#3614)
VideoDecoderCache used an unbounded dict keyed on absolute path, with no
eviction in the standard LeRobotDataset path. With shuffled iteration over
datasets that have many distinct mp4 files, every DataLoader worker
accumulated one cached (VideoDecoder, fsspec file handle) pair per distinct
path it had ever touched. Per-entry cost is ~3-5 MB of host RAM plus one
open FD; at ~8 k entries this is roughly 30 GB per worker.

This was hit in the wild during a SmolVLA training run on a 4,195-episode
SO-101 dataset (8,390 mp4s, two cameras per episode). dmesg showed
anon-rss climbing to 34.9 GB on a single pt_data_worker before the OOM
killer fired ~30 min into training; with --num_workers=8 the per-worker
peak halved to 17.9 GB, which is the expected inverse-scaling signature
when the leak is per-decode and the workload is split across workers. The
working workaround on the affected platform was --dataset.video_backend=pyav,
because the pyav path opens/closes per call and never touches this cache.

Switch the backing store to an OrderedDict and evict LRU entries when the
cap is reached, closing the evicted file handle inside the lock so we do
not leak FDs either. Default cap is DEFAULT_DECODER_CACHE_SIZE = 100,
overridable via LEROBOT_VIDEO_DECODER_CACHE_SIZE or by passing max_size=
to the constructor; max_size=None restores the legacy unbounded behaviour
for callers that need it.

Validation on the original failing workload (decode_video_frames_torchcodec
called over real mp4s from the affected SO-101 dataset):

  unbounded:    300 files  ->  +1087 MB host RSS,  cache=300, still climbing
  cap=50:       500 files  ->   +266 MB host RSS,  cache=50,  stable
  cap=50:      2000 calls  ->   +312 MB host RSS,  cache=50,  stable
  cap=100:     1000 calls  ->   +470 MB host RSS,  cache=100, stable

Three independent seeded runs at cap=50 agreed to within 1% (263 / 266 /
265 MB delta), and the 2000-call multi-pass run shows RSS plateaus after
the cap is reached instead of drifting.

Tests in tests/datasets/test_video_decoder_cache.py cover:
default-is-bounded, size cap, LRU ordering, FD close on eviction, FD close
on clear(), cache-hit invariance, max_size=None fallback, and env-var
override. No regressions in test_video_encoding.py, test_streaming.py, or
test_dataset_reader.py (73 prior tests still pass alongside the 8 new ones).

7ab4936b1b Add extensive language support (#3467)
* Add extensive language support

* Address review: split persistent/event schemas, drop event timestamps

- recipe.py: derive _VALID_ROLES/_VALID_STREAMS from MessageRole/MessageStream Literals
- dataset_metadata.py: keep CODEBASE_VERSION at v3.0
- language.py: remove RESERVED_STYLES; split arrow/feature schemas into
  persistent (with timestamp) and event (without timestamp); add docstrings
- language_render.py: events use frame-row timestamp implicitly; no
  per-event timestamp filtering or sorting
- converters.py: drop unused subtask_key passthrough
- add docstrings to new public APIs (recipe, render_messages_processor, collate)
- update tests for split schemas; revert uv.lock

* Add docstrings to all new helpers; revert uv.lock

Covers private helpers in recipe.py, language.py, language_render.py,
and render_messages_processor.py. Also reverts uv.lock to main (it was
re-generated by `uv run` during local checks).

* feat(language): add motion (persistent) and trace (event-only) styles

Promote the previously-reserved motion/trace styles to first-class core
styles. motion routes to language_persistent (it tracks robot state over
time); trace routes to language_events (single-moment annotations).

* feat(language): per-camera tagging on view-dependent styles

Adds a nullable `camera` field to the language row struct (both persistent
and event variants) so view-dependent styles like `vqa` can carry which
`observation.images.*` view they were grounded against. Without this,
multi-camera datasets ended up with multiple `(vqa, role)` rows at the
same timestamp that the resolver could not disambiguate.

- `language.py`: add `camera` to PERSISTENT_ROW_FIELDS / EVENT_ROW_FIELDS,
  to both Arrow struct types and the HF datasets feature mappings;
  introduce VIEW_DEPENDENT_STYLES = {vqa, motion, trace} plus
  `is_view_dependent_style` and `validate_camera_field` helpers (camera
  required iff style is view-dependent).
- `language_render.py`: thread an optional `camera=` kwarg through every
  resolver (`active_at`, `emitted_at`, `nth_prev`, `nth_next`) and through
  `_matching_rows` / `_select_*`, so recipes can disambiguate per-camera
  VQA with `emitted_at(t, style=vqa, role=assistant, camera=...)`.
  Without a `camera` filter, multi-row matches keep raising the existing
  ambiguity error — which is the desired behaviour on multi-camera data.
- `recipes/pi05_hirobot.yaml`: replace the single `ask_vqa` branch with
  `ask_vqa_top` and `ask_vqa_wrist` per-camera sub-recipes (each carrying
  the matching image block), keeping the original 0.20 budget and
  documenting the customization point for datasets with different cameras.
- Tests: schema test asserts the new field order; new tests cover
  `is_view_dependent_style`, `validate_camera_field` (both required and
  forbidden directions), per-camera `emitted_at` filtering, and the
  ambiguity error when two cameras emit `(vqa, assistant)` at the same
  timestamp without a `camera=` filter. RenderMessagesStep + dataset
  passthrough fixtures updated to include the new field.
- `docs/source/language_and_recipes.mdx`: document the `camera` field,
  the per-camera resolver pattern, and the canonical recipe convention.

* fix(language): drop motion from VIEW_DEPENDENT_STYLES

Motion primitives are described in robot-frame (joint / Cartesian) terms,
not pixel space, so they are camera-agnostic. Only `vqa` (event) and
`trace` (event, pixel-trajectory) are view-dependent.

The `camera` field stays on PERSISTENT_ROW_FIELDS for schema symmetry —
the validator, resolver, and HF feature mapping behave identically across
the two columns regardless of which styles populate `camera` today —
but persistent rows now always have `camera=None` in practice.

* feat(language): task_aug style + automatic ${task} rephrasing rotation

Adds task-prompt diversity (Xiao 2022 / CAST) without touching
``meta/tasks.parquet`` or forcing recipes to opt in. The plan reserved
``task_aug`` as a future style; this lands it now.

- ``language.py``: add ``task_aug`` to ``CORE_STYLES`` and
  ``PERSISTENT_STYLES``. ``column_for_style("task_aug")`` returns
  ``language_persistent`` so PR 2 writers route it correctly.

- ``language_render.py``: ``_resolve_task`` now consults the persistent
  slice for rows of ``style="task_aug", role="user"``. When any exist
  it picks one deterministically by ``sample_idx`` (blake2b-keyed, not
  Python's randomized hash) so an epoch sees every rephrasing of every
  episode while the same sample still resolves identically across
  reruns. Falls back to the canonical ``meta/tasks.parquet`` task when
  no rephrasings are present, so existing datasets and unannotated runs
  keep their behaviour. Explicit ``task=`` overrides still win.

- Tests: rephrasing coverage across samples, determinism on repeat
  ``sample_idx``, fallback when persistent has no ``task_aug`` rows,
  and explicit override priority.

Recipes get this for free: any ``${task}`` placeholder rotates through
the available rephrasings. Recipes that want the literal canonical task
can override the binding.

* feat(language): tool catalog in meta/info.json + LeRobotDatasetMetadata.tools

Stores OpenAI-style function schemas at ``meta/info.json["tools"]`` so
datasets can declare which tools are available (today: just ``say``;
tomorrow: per-dataset extensions). The ``DEFAULT_TOOLS`` constant
fills in for unannotated datasets so chat-template consumers don't
have to special-case anything.

Three pieces:

- ``language.py``: ``SAY_TOOL_SCHEMA`` and ``DEFAULT_TOOLS``
  constants. Single source of truth — PR 2's writer and PR 3's
  runtime tool registry will both import from here instead of
  duplicating the dict.
- ``dataset_metadata.py``: ``LeRobotDatasetMetadata.tools`` property
  reads ``info.json["tools"]`` and falls back to ``DEFAULT_TOOLS``.
  Returns deep-copied dicts so callers can mutate the result safely.
- ``docs/source/tools.mdx``: spec page covering the catalog, per-row
  invocations, and the three-step "how to add a new tool" workflow
  (declare schema, implement, register). Linked from the docs
  toctree under the Datasets section.

This lays the groundwork for PR 2's pipeline writing the catalog out
during annotation, and PR 3's ``src/lerobot/tools/`` package shipping
runnable implementations (one file per tool — first up:
``say.py`` wrapping Kyutai's pocket-tts).

* refactor(language): unify resolver dispatch and prune redundant test scaffolding

* Drop the unused `events` kwarg from `active_at`/`nth_prev`/`nth_next`;
  only `emitted_at` actually consults events. The dispatcher in
  `_resolve_spec` now passes events conditionally.
* Replace the dual `_persistent_sort_key`/`_event_sort_key` pair with a
  single `_row_sort_key` and drop the `sort_key` parameter from
  `_select_one`. Event rows lack `timestamp` (it is implicit in the
  frame) and now default to `0.0` for sort purposes — the
  `(style, role)` tiebreaker is unchanged.
* Inline `_select_latest` into `active_at` (its only caller).
* Collapse `emitted_at`'s dual-branch into one `_select_one` call.
* Tighten `_validate_persistent_resolver` to a single
  `column_for_style(style) != LANGUAGE_PERSISTENT` check.
* Parameterize `test_per_camera_blend_renders_both_views` over the two
  cameras and factor the sub-recipe builder into `_vqa_subrecipe` so
  the test no longer hand-rolls two near-identical recipe blocks.

Net -98 LOC; behavior, public resolver names, and test expectations
unchanged.

* fix(language): always raise on ambiguous resolver matches

`_select_one` previously skipped its ambiguity check whenever any of
`role`/`tool_name`/`camera` was set, on the assumption that the caller
had already pinned down a unique row. That left a real ambiguity hole
for VQA: with two cameras emitting `(vqa, assistant)` at the same
frame, `emitted_at(..., role="assistant")` silently picked the first
sorted row instead of telling the recipe to add `camera=...`. The
existing `test_emitted_at_raises_on_ambiguous_per_camera_vqa` test
already encoded the desired behavior.

Tighten the check: any time `len(rows) > 1` we now raise with the
selectors echoed back, so users see exactly which fields they passed
and that more is needed to disambiguate.

* chore: fix CI — collapse short ValueError to one line, refresh uv.lock

* `ruff format` on CI (newer version) wants the short `camera=None`
  ValueError on a single line.
* `uv.lock` was stale relative to `pyproject.toml`'s `datasets>=4.7.0`
  pin (and picked up upstream `s390x` marker fixes for cuda packages).
  CI runs `uv sync --locked` which rejected the divergence.

* fix(language): keep base install green — drop processor re-export, gate dataset-extra tests

`lerobot.processor` re-exported `RenderMessagesStep` at the package
level, so importing anything from `lerobot.processor` pulled in
`lerobot.datasets.language` → `lerobot.datasets/__init__.py` →
`require_package("datasets")`, which fails in the Tier 1 base install
that intentionally omits the `[dataset]` extra. The chain bricked
collection for unrelated suites (`tests/policies/pi0_pi05/...`,
`tests/envs/...`, etc.).

* Stop re-exporting `RenderMessagesStep` from `lerobot.processor`. The
  only consumer (the test) already imports from the submodule.
  Document the deliberate omission in the module docstring.
* Add `pytest.importorskip("datasets", ...)` (and `pandas` where
  needed) at the top of the four PR-added tests that exercise the
  language stack:
  - tests/datasets/test_language.py
  - tests/datasets/test_language_render.py
  - tests/processor/test_render_messages_processor.py
  - tests/utils/test_collate.py

* fix(language): address review — tools accessor, motion docs, conditional collate

* **`meta.tools` actually reads `info.json["tools"]`.** `DatasetInfo`
  had no `tools` field, so `from_dict` silently dropped the key (it
  warned about unknown fields then discarded them) and the property
  always returned `DEFAULT_TOOLS`. Added `tools: list[dict] | None`
  to the dataclass; `to_dict()` drops it when unset so existing
  datasets keep a clean `info.json`. Fixed the accessor to read
  `self.info.tools` (the previous `.get(...)` would have raised
  AttributeError on the dataclass anyway). Added regression tests:
  fallback when absent, round-trip from disk, and round-trip
  through `DatasetInfo.from_dict` / `to_dict`.

* **`motion` is not view-dependent — fix the docs.** The mdx claimed
  rows of style `motion` must carry `camera`, but `VIEW_DEPENDENT_STYLES
  = {"vqa", "trace"}` and the validator agrees: motion primitives are
  joint/Cartesian-frame, not pixel-space. Updated both call-out
  paragraphs in `language_and_recipes.mdx`.

* **Conditional `collate_fn` swap.** Added `meta.has_language_columns`
  and gate the `lerobot_collate_fn` swap in `lerobot_train.py` on it,
  so non-language datasets keep PyTorch's `default_collate`. Also
  added a pass-through test in `test_collate.py` that asserts on a
  plain tensor batch the custom collate matches `default_collate`
  key-for-key, plus a test for the `None`-sample drop path.

* review: dedupe regex, centralize column names, harden collate, more tests

* **#2 — dedupe `_PLACEHOLDER_RE`.** The same regex was compiled in
  `recipe.py` and `language_render.py`. Promote to module-level
  `PLACEHOLDER_RE` in `recipe.py` (its primary owner — declares
  template syntax) and import from `language_render.py`.
* **#3 — centralize language column names.** `io_utils.py` had
  hardcoded `{"language_persistent", "language_events"}` literals at
  two sites. Replace with `LANGUAGE_COLUMNS` import so a future column
  rename can't silently desync.
* **#4 — defensive collate preserved-keys.** `lerobot_collate_fn`
  silently filtered language fields from samples that didn't have
  them, which would hand downstream consumers a preserved list
  shorter than the tensor batch. Now: if any sample carries a key,
  every sample in the batch must carry it; otherwise raise a
  `ValueError` so the upstream rendering bug surfaces at the boundary.
* **#5 — `_scalar` rejects non-singleton lists.** Previously a zero-
  or multi-element list fell through and triggered confusing
  `float([])` errors downstream. Now raises `ValueError` with the
  actual length.
* **#6 — refactor `_extract_complementary_data`.** Replace 11 lines
  of `key = {... if ... else {}}` plus an 11-line splat dict with a
  single `_COMPLEMENTARY_KEYS` tuple iterated once.
* **#7 — document `EXTENDED_STYLES`.** Was an empty `set()` with no
  comment. Add a docstring explaining it's an intentional extension
  point: downstream modules append project-local styles before
  `column_for_style` is called.
* **#9 — `tools.mdx` notes the runtime layer is future work.** The
  page referenced `src/lerobot/tools/`, `registry.py`, and
  `get_tools(meta)` — none exist in this PR. Added a callout at the
  start of "How to add your own tool" plus a note on the
  implementations paragraph.
* **#10 — tests for YAML round-trip, malformed rows, blend
  validation.** `test_recipe.py` grew from 1 case to 12 covering:
  blend-or-messages exclusivity, target-turn requirement, blend
  emptiness, weight presence/positivity, nested-blend rejection,
  `from_dict` with nested blends, `from_yaml` / `load_recipe`
  agreement, top-level non-mapping rejection. Added a malformed-row
  test for `_normalize_rows` that asserts non-dict entries raise
  `TypeError`.

* review: emitted_at uses 0.1s tolerance; MessageTurn requires stream at construction

* **Float tolerance in `emitted_at` for persistent styles.** The
  ``_timestamp(row) == t`` exact-equality check silently missed any
  caller that derived ``t`` arithmetically (e.g. ``frame_idx / fps``)
  even though the parquet timestamp would only differ by ULPs. Added
  ``EMITTED_AT_TOLERANCE_S = 0.1`` and check ``abs(...) <= tolerance``
  instead, with a docstring explaining why exact equality wasn't
  enough and why 0.1 s is safe at typical 30–100 Hz control rates.
  Test asserts the new behavior at half-window (matches) and
  double-window (no match) using the constant so it stays in sync.

* **`MessageTurn.stream` is required at construction.** It was typed
  ``MessageStream | None = None`` so YAML could omit ``stream:`` and
  pass the dataclass invariant — but ``_validate_rendered`` rejected
  ``None`` streams later, surfacing the error at the first sample
  instead of at recipe load. Now ``__post_init__`` raises
  ``ValueError`` if ``stream`` is ``None``, with the list of valid
  streams in the message. The redundant late-stage check in
  ``_validate_rendered`` is replaced with a one-line comment that
  cites the upstream invariant. Test pins the new construction-time
  rejection.

* docs(tools): drop follow-up-PR references

Reword the two callouts in `tools.mdx` to describe the runtime layer
in present tense ("not part of the catalog layer shipped today",
"those modules don't yet exist in the tree") instead of pointing at a
specific follow-up PR. Keeps the doc honest about what works now
without coupling it to a particular release order.

  timestamps (Arrow struct + HF feature)
- dataset_metadata: hoist `.language` imports to module top — language.py

- dataset_metadata: add a `meta.tools` setter that persists the catalog to
  info.json and reloads `meta.info`
- feature_utils: validate the `language` dtype instead of returning "" —
  warn (non-fatal) when a non-empty value is written at record time
- centralize the scalar-unwrap helper as `lerobot.utils.utils.unwrap_scalar`,
  shared by render_messages_processor and language_render
- docs: move `## Layer 2 — recipe anatomy` ahead of the resolver sections,
  which describe recipe bindings rather than dataset layout
- language_render: note in EMITTED_AT_TOLERANCE_S that persistent rows change
  on a human-action timescale, not the camera frame rate

3c15fd8537 feat(robots): natively integrate Seeed Studio reBot B601-DM arm (#3624)
* feat(robots): natively integrate Seeed Studio reBot B601-DM arm

Add first-class LeRobot support for the Seeed Studio reBot arm, replacing
the out-of-tree `lerobot-robot-seeed-b601` / `lerobot-teleoperator-rebot-arm-102`
plugin packages.

New devices:
- robot `rebot_b601_follower` — single-arm B601-DM follower (6-DOF + gripper,
  Damiao CAN motors via `motorbridge`)
- robot `bi_rebot_b601_follower` — bimanual follower composing two single arms
- teleoperator `rebot_102_leader` — single-arm StarArm102 / reBot Arm 102 leader
  (FashionStar UART servos via `motorbridge-smart-servo`)
- teleoperator `bi_rebot_102_leader` — bimanual leader composing two single arms

The bimanual variants reuse the single-arm classes and namespace each arm's
observation/action keys with `left_` / `right_` prefixes, so a bimanual
StarArm102 leader can teleoperate a bimanual reBot B601 follower.

Optional SDK imports are guarded; a `rebot` extra installs `motorbridge` and
`motorbridge-smart-servo`.

* docs: add reBot B601-DM calibration & dual-arm teleoperation guide

Add docs/source/rebot_b601.mdx covering single-arm and bimanual
calibration and teleoperation for the reBot B601-DM follower and
reBot Arm 102 leader, with zero-position reference images from the
Seeed Studio wiki. Register the page in the docs toctree.

the colocated rebot_b601.md was a redundant thinner copy.

* docs: clarify 6-DOF leader fallback comment in reBot B601 follower

Explain that holding wrist_yaw at zero is what lets a 6-DOF leader
(e.g. so100_leader / so101_leader) teleoperate the 7-DOF follower.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* refactor: address Caroline's PR review on reBot B601 integration

- leader: remove _validate_config (no other lerobot device validates its
  config; a key mismatch now surfaces as a plain KeyError)
- leader: simplify _round_to_valid_range to direct modular arithmetic
  instead of a bidirectional search loop
- leader: inline the single-use _clamp helper
- follower & leader: write MotorCalibration range_min/range_max from the
  configured joint_limits / joint_ranges instead of a fixed [-90, 90]
- docs: add a "Find the USB ports" section (lerobot-find-port) and move
  the brltty/permissions tip there; link the OpenArm page for SocketCAN
  adapter configuration

9db9c35cb4 fix(config): add lora_alpha to PeftConfig (#3573)
* fix(config): add lora_alpha to PeftConfig

PeftConfig was missing the lora_alpha field, causing the PEFT library
to default to alpha=8 regardless of the LoRA rank, which dampens the
adaptation signal for high-rank adapters (e.g., r=128).

This adds lora_alpha: int | None = None to PeftConfig, allowing users
to specify --peft.lora_alpha <value> on the CLI.

Closes #3551

* fix(docs): add lora_alpha to peft training example + clarify scaling formula

- Add --peft.lora_alpha=64 to docs/source/peft_training.mdx example to
  prevent new users from hitting the alpha=8 default dampening bug
- Clarify lora_alpha comment in default.py with scaling = lora_alpha / r

* docs: mention both --peft.r and --peft.lora_alpha in LoRA description

fe96b28c74 Fix policy.path not working in YAML config files (#3145)
* fix(config): support policy.path in YAML config files

policy.path was only handled via CLI args (filtered from sys.argv before
draccus, then retrieved in validate()). When specified in YAML, draccus
would crash because 'path' is not a valid field on PreTrainedConfig.

Extract path fields from the YAML/JSON config before draccus processes
it, store them in a module-level dict, and fall back to it in
get_path_arg() when the CLI doesn't have the path.

Fixes #2957

* fix(parser): preserve YAML policy overrides when loading from pretrained

When policy.path is set in YAML, validate() was calling from_pretrained
with only CLI overrides, discarding any YAML policy fields (e.g. lr,
batch_size) that draccus had already parsed. Fix by capturing the
remaining YAML fields as CLI-style args in _config_yaml_overrides and
merging them into the overrides passed to from_pretrained in train.py,
eval.py, and lerobot_record.py (CLI args still take precedence).

Also fix the NamedTemporaryFile SIM115 ruff warning and add types-PyYAML
to the mypy pre-commit hook.

* fix(parser): serialize bool/None values correctly in YAML policy overrides

Bool values from YAML configs (e.g. push_to_hub: true) were passed as
Python "True"/"False" strings instead of lowercase "true"/"false" that
draccus expects. Also skip None values to avoid passing "None" strings.

* revert: remove types-PyYAML from .pre-commit-config.yaml

* chore: fix quality check caused by untyped YAML import

1f7b03f5f2 chore(deps): allow torch 2.11/2.12 and fix autocast deprecation (#3435)
* chore(deps): allow torch 2.11/2.12 and fix autocast deprecation

- Bump torch to >=2.7,<2.13 (was <2.11), torchvision to <0.28 (was <0.26),
  and torchcodec to <0.13 (was <0.11) to allow installs against the latest
  stable torch 2.11 and the upcoming 2.12 line.
- Replace removed torch.get_autocast_gpu_dtype() with torch.get_autocast_dtype("cuda")
  in Florence2 and Qwen2.5-VL-MoE FlashAttention paths (the former is removed in 2.11+).
- Refresh uv.lock for the new resolution (torch 2.11.0+cu130, torchvision 0.26.0+cu130,
  torchcodec 0.11.1, full CUDA 13 stack).

Verified locally with `uv sync --locked` from a clean .venv and the lerobot
test suite (pytest -n 8 --dist=loadfile --timeout=300). Failure set is
identical to the pre-bump baseline: 18 pre-existing failures
(test_sac_policy*, test_pi0_rtc*, test_pi05_rtc*, test_replay_buffer*),
0 new, 0 fixed.

AI assistance: this change was authored with Claude Code per AI_POLICY.md.

* fix(policies): use device-agnostic autocast dtype lookup

Pass query_states.device.type to torch.get_autocast_dtype() instead of
hardcoding 'cuda', so the cast matches the active autocast context when
running under CPU/MPS/XPU autocast.

1add460678 fix(policy): loss normalization for padded actions in ACT, Diffusion, and MultiTaskDiT (#3442)
* Fix loss normalization for padded actions in ACT, Diffusion, and MultiTaskDiT

When action_is_pad masks out padded timesteps, the subsequent .mean()
still divides by the total element count (including zeroed-out padding),
underestimating the loss. With 60-70% padding this can cut the effective
gradient signal by 2-3x.

Replace mask-then-mean with mask-then-sum / valid-count for all three
affected policies. TDMPC is not affected because it sums over time
before averaging over batch.

Fixes #3353

2236cdb302 fix(smolvla): correct loss normalization for padded actions (#3434)
Apply the same per-scalar-mean fix to SmolVLA that #3377 landed for
ACT / Diffusion / MultiTaskDiT. The pre-patch form applies the
`action_is_pad` mask to zero out padded timesteps, then calls `.mean()`
(or `.mean(dim=(1, 2))`). Because `.mean()` divides by the total number
of elements including the zeroed padding, the loss is diluted by the
padding fraction.

Fixed by normalizing only over valid (non-padded) scalar entries:

    num_valid = ((~actions_is_pad).sum(...) * losses.shape[-1]).clamp_min(1)
    loss = losses.sum(...) / num_valid

`clamp_min(1)` preserves the all-padded-batch edge case (0/1 = 0). Both
reduction paths are updated. Behavior when `action_is_pad` is missing is
unchanged (`losses.mean()`).

Empirical A/B on aloha_sim_transfer_cube_human (chunk_size=40, batch=2,
30 steps, fixed seed, GB200) shows `loss_A / loss_B = 0.9672 (±0.088)` —
same direction and magnitude as PR #3377's `loss_A / loss_C ≈ 0.96` for
ACT. Heavier-padding recipes will see a larger gap.

Refs: #3353 (original report for ACT), #3377 (fix for the other three
policies).

5adad11128 feat(sim): VLABench benchmark integration (#3396)
feat(sim): add VLABench benchmark integration
Add VLABench as a new simulation benchmark in LeRobot, following the existing LIBERO and MetaWorld patterns.
This PR wires VLABench end-to-end across environment integration, Docker setup, CI smoke evaluation, and documentation. It also fixes a number of upstream packaging and runtime issues required to make VLABench usable and reproducible in CI.
What’s included
Benchmark integration
Add VLABench as a new simulation benchmark.
Expose supported VLABench tasks through the LeRobot env interface.
Follow the established LIBERO / MetaWorld factory patterns.
Preserve lazy async-env metadata so env.unwrapped.metadata["render_fps"] continues to work.
CI smoke evaluation
Add a VLABench smoke-eval job using lerobot/smolvla_vlabench.
Use the correct rename_map for the 3-camera dataset layout.
Expand smoke coverage from 1 to 10 primitive tasks.
Extract task descriptions after eval so metrics artifacts include per-task labels.
Skip Docker Hub login when secrets are unavailable (e.g. fork PRs).
Docker / install fixes
Install VLABench from GitHub rather than PyPI.
Use uv pip, not pip, in the base image.
Fail loudly on install errors instead of masking them.
Clone VLABench into the non-root user’s home directory.
Use shallow editable installs for VLABench and rrt-algorithms to work around missing __init__.py issues.
Pin upstream clones to exact commit SHAs for reproducibility.
Add undeclared runtime dependencies required by VLABench (open3d, colorlog, scikit-learn, openai).
Unpin open3d so Python 3.12 wheels resolve.
Assets
Support downloading VLABench assets from a Hugging Face Hub mirror via VLABENCH_ASSETS_REPO.
Keep Google Drive download support as fallback.
Install huggingface_hub[hf_xet] so Xet-backed assets download correctly.
Validate required mesh/XML asset subtrees at build time.
Patch VLABench constants to tolerate missing asset directories at import time.
Runtime / env correctness
Import VLABench robots and tasks explicitly so decorator-based registry population happens.
Resize and normalize camera observations so they always match the declared (H, W, 3) uint8 observation space.
Reinstall LeRobot editably inside the image so the new env code is actually used.
Coerce agent_pos / ee_state to the expected shape.
Pad actions when needed to match data.ctrl.
Replace zero-padding fallback with proper dm_control IK for 7D end-effector actions.
Refetch dm_control physics on each step instead of caching weakrefs.
Retry unstable resets with reseeding and handle PhysicsError gracefully at step time.
Dataset / policy alignment
Align VLABench observations and actions with Hugging Face dataset conventions used by lerobot/vlabench_unified:
convert EE position between world frame and robot-base frame at the env boundary,
expose / consume Euler XYZ instead of raw quaternion layout,
align gripper semantics with dataset convention (1 = open, 0 = closed).
This fixes policy/env mismatches that previously caused incorrect IK targets and unstable behavior at evaluation time.
Docs
Add a full docs/source/vlabench.mdx page aligned with the standard benchmark template.
Document task selection forms (single task, comma list, suite shortcut).
Document installation, evaluation, training, and result reproduction.
Point examples at lerobot/smolvla_vlabench.
Add a benchmark banner image.
Remove outdated / misleading references to upstream evaluation tracks.
Document manual install flow instead of a broken vlabench extra.
Packaging cleanup
Remove the unresolvable vlabench extra from pyproject.toml.
Remove the no-op VLABench processor step.
Remove the obsolete env unit test that only covered the dropped gripper remap helper.
Apply formatting / logging / style cleanup from review feedback.
Why this is needed
VLABench is not currently consumable as a normal Python dependency and requires several upstream workarounds:
no PyPI release,
missing package declarations,
undeclared runtime deps,
SSH-only submodule references,
asset downloads outside normal package install flow,
registry population that depends on import side effects,
env outputs that do not always match declared observation shapes,
task resets that can diverge under some random layouts.
This PR makes the benchmark usable in LeRobot despite those constraints, and ensures CI runs are reproducible and informative.
If you want a much shorter squash commit message, I’d use this:
feat(sim): integrate VLABench benchmark with CI, Docker, and docs
Add VLABench as a new LeRobot simulation benchmark, following the existing LIBERO / MetaWorld patterns.
This includes:
LeRobot env integration and task exposure,
CI smoke eval with lerobot/smolvla_vlabench,
Docker install and asset-download fixes,
runtime fixes for registry loading, assets, camera obs, action handling, dm_control IK, and PhysicsError recovery,
alignment of obs/action semantics with HF VLABench datasets,
docs and packaging cleanup.
The PR also incorporates review feedback, improves reproducibility by pinning upstream commits, and makes VLABench usable in CI despite upstream packaging and asset-management issues.

a07f22e22c feat(envs): add LIBERO-plus robustness benchmark (#3313)
* feat(envs): add LIBERO-plus robustness benchmark integration

- LiberoPlusEnv config (subclass of LiberoEnv, same gym interface)
- Docker image installing LIBERO-plus fork via PYTHONPATH
- CI workflow: 1-episode smoke eval with pepijn223/smolvla_libero_plus
- pyproject.toml: libero_plus extra

* fix(libero): use suite's perturbation-aware init_states loader

LIBERO-plus's Benchmark class exposes a `get_task_init_states(i)` method that
strips perturbation suffixes (`_table_N`, `_tb_N`, `_view_`, `_language_`,
`_light_`, `_add_`, `_level`) and loads the underlying base `.pruned_init`
file — the on-disk name for a perturbation variant doesn't exist as a file,
only the base does. lerobot's loader was bypassing that logic and trying to
read the suffix-bearing filename directly, which failed for every non-zero
task id and killed the eval before any rollout video could be written.

Delegate to the suite's method when it exists; fall back to the path-based
loader for vanilla LIBERO (which does not provide the method).

Also drop the hf-libero install + init_files copy from the LIBERO-plus
Dockerfile — the LIBERO-plus clone already ships both `bddl_files/` and
`init_files/` for all five suites, so the copy was unnecessary and the
`cp -r` into an existing dir produced a confusing nested layout.

* fix(libero): resolve LIBERO-plus perturbation init_states path ourselves

Delegating to `task_suite.get_task_init_states(i)` works for path resolution
but LIBERO-plus's method calls `torch.load(path)` without `weights_only=False`,
which fails on PyTorch 2.6+ because the pickled init_states contains numpy
objects not in the default allowlist:

    _pickle.UnpicklingError: Weights only load failed.
    WeightsUnpickler error: Unsupported global:
      GLOBAL numpy.core.multiarray._reconstruct was not an allowed global.

Mirror LIBERO-plus's suffix-stripping logic (`_table_N`, `_tb_N`, `_view_`,
`_language_`, `_light_`, `_add_`, `_level`) in our own helper so we can pass
`weights_only=False` ourselves. Vanilla LIBERO task names don't contain any
of these patterns except for `_table_` when followed by the word `center`
(e.g. `pick_up_the_black_bowl_from_table_center_...`), and the regex
requires `_table_\\d+` so semantic uses are preserved.

* fix(libero-plus): download perturbation assets from Sylvest/LIBERO-plus

LIBERO-plus's bddl_base_domain.py resolves scene XMLs with
`os.path.join(DIR_PATH, "../assets")`, so the `assets` key in config.yaml
has no effect on scene lookup — MuJoCo always opens
`<clone>/libero/libero/assets/scenes/...`. With no such directory present,
every perturbation task fails on:

    FileNotFoundError: No such file or directory:
      .../libero-plus/libero/libero/assets/scenes/tabletop_table_Cobblestone01_GLOSS_6K.xml

These textures, views, and extra objects ship only in the 6.4 GB `assets.zip`
published at `Sylvest/LIBERO-plus` (the LIBERO-plus README explicitly says
to download and unzip it into the package dir). Fetch it via `hf_hub_download`,
unzip into `${LIBERO_PLUS_ROOT}/`, install `unzip`, and point config.yaml at
the extracted dir so everything stays consistent. The download lives in its
own Docker layer so subsequent rebuilds reuse the cached assets.

Drops the lerobot/libero-assets snapshot_download — that mirror only has
vanilla LIBERO textures and is ignored for scene loading anyway.

* fix(libero-plus): flatten deep path prefix from Sylvest/LIBERO-plus assets.zip

The 6.4 GB zip ships with every entry prefixed by
`inspire/hdd/project/embodied-multimodality/public/syfei/libero_new/release/dataset/LIBERO-plus-0/assets/...`
(the author's internal filesystem layout, not the layout the LIBERO-plus
README promises), so the previous `unzip -d ${LIBERO_PLUS_ROOT}/` created
`${LIBERO_PLUS_ROOT}/inspire/.../assets/` — robosuite still opened
`${LIBERO_PLUS_ROOT}/assets/scenes/tabletop_table_Cobblestone01_GLOSS_6K.xml`
and hit the same FileNotFoundError.

Extract to a scratch dir, then `mv` the nested `assets/` subtree to the
expected location. Verified the target file exists in the zip central
directory under that exact prefix.

* refactor(libero): inline init_states resolver behind single regex

Collapse the three-style suffix stripper (split/re.sub/in) into one
compiled regex, drop the (Path, bool) tuple return, and move the
`_add_`/`_level` reshape branch into the caller so each branch loads
its own file and returns directly. Net: -11 lines, one fewer helper.

* refactor(libero-plus): rebase docker image on huggingface/lerobot-gpu

Mirror the libero/metaworld/robomme pattern: start from the nightly GPU
image (apt deps, python, uv, venv, lerobot[all] already there) and only
layer on what LIBERO-plus uniquely needs — its wand/ImageMagick build
deps, the non-extra runtime pips (robosuite==1.4.1, bddl, …), the
PYTHONPATH-shadowed fork, and the 6.4 GB assets.zip.

Drops ~50 lines of duplicated base setup (CUDA FROM, apt python, uv
install, user creation, venv init) the nightly already provides.
123 → 73 lines.

Also:
- Add libero_plus to docs/source/_toctree.yml under Benchmarks so
  doc-builder's TOC integrity check stops failing.
- Repoint the docs dataset link from pepijn223/libero_plus_lerobot to
  the canonical lerobot/libero_plus.
- Revert the stray uv.lock churn (revision/marker diff that crept in
  from an unrelated resolve — unrelated to LIBERO-plus).

* fix(libero-plus): stop touching pyproject + uv.lock

The fast-tests job was rejecting the branch because pyproject.toml had a
[libero_plus] extra whose git dep wasn't represented in uv.lock.

The Docker image no longer needs the extra — it clones LIBERO-plus
directly and PYTHONPATH-shadows hf-libero. Drop [libero_plus] from
pyproject and restore pyproject.toml + uv.lock to exactly what's on
origin/main, so `uv sync --locked --extra test` is a no-op for this PR.

Also repoint the doc/CI/env comments that still mentioned the extra at
the Docker install path.

* fix(libero-plus): strip perturbation metadata from task descriptions

LIBERO-plus builds task.language by space-joining the perturbation-variant
filename, so every non-_language_ variant inherits a trailing blob like
"view 0 0 100 0 0 initstate 0 noise 45" or "add 16". That shows up in the
dashboard video labels and no longer matches the base instruction stored
in the training dataset.

Strip those tokens in extract_task_descriptions.py with an end-anchored
regex over the {view,initstate,noise,add,tb,table,light,level}(+digits)
vocabulary. The anchor preserves mid-sentence literal uses of those words
(e.g. "from table center and place it on the plate") — only the trailing
metadata chain is removed. _language_ variants carry real BDDL-sourced
text and are left untouched.

* ci: point benchmark eval checkpoints at the lerobot/ org mirrors

pepijn223/smolvla_* → lerobot/smolvla_* across every benchmark job in
this branch (libero, metaworld, and the per-branch benchmark). The
checkpoints were mirrored into the lerobot/ org and that's the canonical
location going forward.

* fix(docs): use correct LIBERO-plus teaser image URL

* ci(libero-plus): drop redundant hf auth login step

The standalone login step ran `hf auth login` in a throwaway
`docker run --rm` container, so no credentials persisted. Auth is
already performed inside the eval step's container. Removing the
redundant step per PR #3313 review feedback.

* fix(envs): preserve AsyncVectorEnv metadata/unwrapped in lazy eval envs

Port of #3416 onto this branch. Without these attributes eval crashes
when calling `env.unwrapped.metadata["render_fps"]` with async vector
envs. Adds `metadata` / `unwrapped` to `_LazyAsyncVectorEnv` and
caches the metadata alongside obs/action spaces in the LIBERO and
MetaWorld factories.

* ci: gate Docker Hub login on secret availability

Fork PRs cannot access `secrets.DOCKERHUB_LEROBOT_{USERNAME,PASSWORD}`,
which made every benchmark job fail at the login step before any of
the actual build/eval work could run. Gate the login on the env-var
expansion of the username so the step is skipped (not failed) when
secrets are absent. Mirrors the existing pattern in the VLABench job.

  location once the dataset is mirrored.

* fix(robomme): make docs build + fast tests green

1. Docs: add robomme to _toctree.yml under Benchmarks so doc-builder's
   TOC integrity check stops rejecting the new page.

2. Fast tests: robomme's mani-skill transitively pins numpy<2 which is
   unsatisfiable against the project's numpy>=2 base pin, so `uv sync`
   couldn't resolve a universal lockfile.

   Drop robomme as a pyproject extra entirely — it truly cannot coexist
   with the rest of the dep tree. The Dockerfile installs robomme
   directly from its git URL via `uv pip install --override`, which was
   already the runtime path. pyproject, docs, env docstrings, and the
   CI job comment all now point to the docker-only install.

* test(robomme): realign unit tests with current env API

The tests were written against an earlier env layout and never updated when
the wrapper was refactored, so CI's fast-test job was failing with:

- KeyError: 'front_rgb' / 'wrist_rgb' — these were renamed to the
  lerobot-canonical 'image' / 'wrist_image' keys (matching the dataset
  columns and preprocess_observation's built-in fallbacks).
- AssertionError: 'robomme' not in result — create_robomme_envs now
  returns {task_name: {task_id: env}}, not {'robomme': {...}}, so
  comma-separated task lists work.
- ModuleNotFoundError: lerobot.envs.lazy_vec_env — LazyVectorEnv was
  removed; create_robomme_envs is straightforward synchronous now.

Rewrite the 7 failing cases against the current API, drop the three
LazyVectorEnv tests, and add a multi-task test so the new comma-separated
task parsing is covered. Stub install/teardown is moved into helpers
(`_install_robomme_stub` / `_uninstall_robomme_stub`) so individual tests
stop repeating six boilerplate lines.

Updated the parse_eval_metrics.py `--task` label from the single

`_convert_obs` was returning flat keys (`pixels/image`,

keys off the top-level `"pixels"` entry and, not finding it,
silently dropped every image from the batch. The policy then saw
zero image features and raised

    ValueError: All image features are missing from the batch.

`{"pixels": {"image": ..., "wrist_image": ...}, "agent_pos": ...}`
and declare the same shape in `observation_space`.

0f1c9b0851 feat(envs): add RoboTwin 2.0 benchmark (#3315)
* feat(envs): add RoboTwin 2.0 benchmark integration

- RoboTwinEnvConfig with 4-camera setup (head/front/left_wrist/right_wrist)
- Docker image with SAPIEN, mplib, CuRobo, pytorch3d (Python 3.12)
- CI workflow: 1-episode smoke eval with pepijn223/smolvla_robotwin
- RoboTwinProcessorStep for state float32 casting
- Camera rename_map: head_camera/front_camera/left_wrist -> camera1/2/3

* fix(robotwin): re-enable autograd for CuRobo planner warmup and take_action

lerobot_eval wraps the full rollout in torch.no_grad() (lerobot_eval.py:566),
but RoboTwin's setup_demo → load_robot → CuroboPlanner(...) runs
motion_gen.warmup(), which invokes Newton's-method trajectory optimization.
That optimizer calls cost.backward() internally, which raises

    RuntimeError: element 0 of tensors does not require grad and does not have a grad_fn

when autograd is disabled. take_action() hits the same planner path at every
step. Wrap both setup_demo and take_action in torch.enable_grad() so CuRobo's
optimizer can build its computation graph. Policy inference is unaffected —
rollout()'s inner torch.inference_mode() block around select_action() is
untouched, so we still don't allocate grad buffers during policy forward.

* fix(robotwin): read nested get_obs() output and use aloha-agilex camera names

RoboTwin's base_task.get_obs() returns a nested dict:

    {"observation": {cam: {"rgb": ..., "intrinsic_matrix": ...}},
     "joint_action": {"left_arm": ..., "left_gripper": ...,
                      "right_arm": ..., "right_gripper": ...,
                      "vector": np.ndarray},
     "endpose": {...}}

Our _get_obs was reading raw["{cam}_rgb"] / raw["{cam}"] and raw["joint_action"]
as if they were flat, so np.asarray(raw["joint_action"], dtype=float64) tripped
on a dict and raised

    TypeError: float() argument must be a string or a real number, not 'dict'

Fix:
- Pull images from raw["observation"][cam]["rgb"]
- Pull joint state from raw["joint_action"]["vector"] (the flat array)
- Update the default camera tuple to (head_camera, left_camera, right_camera)
  to match RoboTwin's actual wrist-camera names (envs/camera/camera.py:135-151)

* refactor(robotwin): drop defensive dict guards, cache black fallback frame

_get_obs was guarding every dict access with isinstance(..., dict) in case
RoboTwin's get_obs returned something else — but the API contract
(envs/_base_task.py:437) always returns a dict, so the guards were silently
masking real failures behind plausible-looking zero observations. Drop them.

Also:
- Cache a single black fallback frame in __init__ instead of allocating
  a fresh np.zeros((H, W, 3), uint8) for every missing camera on every
  step — the "camera not exposed" set is static per env.
- Only allocate the zero joint_state on the fallback path (not unconditionally
  before the real value overwrites it).
- Replace .flatten() with .ravel() (no copy when already 1-D).
- Fold the nested-dict schema comment and two identical torch.enable_grad()
  rationales into a single Autograd section in the class docstring.
- Fix stale `left_wrist` camera name in the observation docstring.

* fix(robotwin): align observation_space dims with D435 camera output

lerobot_eval crashed in gym.vector's SyncVectorEnv.reset with:

    ValueError: Output array is the wrong shape

because RoboTwinEnvConfig declared observation_space = (480, 640, 3) but
task_config/demo_clean.yml specifies head_camera_type=D435, which renders
(240, 320, 3). gym.vector.concatenate pre-allocates a buffer from the
declared space, so the first np.stack raises on shape mismatch.

Changes:
- Config defaults now 240×320 (the D435 dims in _camera_config.yml), with
  a comment pointing at the source of truth.
- RoboTwinEnv.__init__ accepts observation_height/width as Optional and
  falls back to setup_kwargs["head_camera_h/w"] so the env is self-consistent
  even if the config is not in sync.
- Config camera_names / features_map use the actual aloha-agilex camera
  names (head_camera, left_camera, right_camera). Drops the stale
  "front_camera" and "left_wrist"/"right_wrist" entries that never matched
  anything RoboTwin exposes.
- CI workflow's rename_map updated to match the new camera names.

* fix(robotwin): expose _max_episode_steps for lerobot_eval.rollout

rollout() does `env.call("_max_episode_steps")` (lerobot_eval.py:157) to
know when to stop stepping. LiberoEnv and MetaworldEnv set this attribute;
RoboTwinEnv was tracking the limit under `episode_length` only, so the call
raised AttributeError once CuRobo finished warming up.

* fix(robotwin): install av-dep so lerobot_eval can write rollout MP4s

write_video (utils/io_utils.py:53) lazily imports PyAV via require_package
and raises silently inside the video-writing thread when the extra is not
installed — so the eval itself succeeds with pc_success=100 but no MP4
ever lands in videos/, and the artifact upload reports "No files were
found". Add av-dep to the install line (same pattern as the RoboMME image).

* feat(robotwin): eval 5 diverse tasks per CI run with NL descriptions

Widen the smoke eval from a single task (beat_block_hammer) to five:
click_bell, handover_block, open_laptop, stack_blocks_two on top of the
original. Each gets its own rollout video in videos/<task>_0/ so the
dashboard can surface visually distinct behaviours.

extract_task_descriptions.py now has a RoboTwin branch that reads
`description/task_instruction/<task>.json` (already shipped in the clone
at /opt/robotwin) and pulls the `full_description` field. CI cds into
the clone before invoking the script so the relative path resolves.

parse_eval_metrics.py is invoked with the same 5-task list so the
metrics.json embeds one entry per task.

* ci: point benchmark eval checkpoints at the lerobot/ org mirrors

pepijn223/smolvla_* → lerobot/smolvla_* across every benchmark job in
this branch (libero, metaworld, and the per-branch benchmark). The
checkpoints were mirrored into the lerobot/ org and that's the canonical
location going forward.

* refactor(robotwin): rebase docker image on huggingface/lerobot-gpu

Mirror the libero/metaworld/libero_plus/robomme pattern: start from the
nightly GPU image (apt deps, python, uv, venv, lerobot[all] already
there) and layer on only what RoboTwin 2.0 uniquely needs —
cuda-nvcc + cuda-cudart-dev (CuRobo builds from source), Vulkan libs +
NVIDIA ICD (SAPIEN renderer), sapien/mplib/open3d/pytorch3d/curobo
installs, the mplib + sapien upstream patches, and the TianxingChen
asset download.

Drops ~90 lines of duplicated base setup (CUDA FROM, apt python, uv
install, user creation, venv init, base lerobot install). 199 → 110.

Also repoint the docs + env docstring dataset link from
hxma/RoboTwin-LeRobot-v3.0 to the canonical lerobot/robotwin_unified.

* docs(robotwin): add robotwin to _toctree.yml under Benchmarks

doc-builder's TOC integrity check was rejecting the branch because
docs/source/robotwin.mdx existed but wasn't listed in _toctree.yml.


* fix(robotwin): defer YAML lookup and realign tests with current API

__init__ was eagerly calling _load_robotwin_setup_kwargs just to read
head_camera_h/w from the YAML. That import (`from envs import CONFIGS_PATH`)
required a real RoboTwin install, so constructing the env — and thus every
test in tests/envs/test_robotwin.py — blew up with ModuleNotFoundError
on fast-tests where RoboTwin isn't installed.

Replace the eager lookup with DEFAULT_CAMERA_H/W constants (240×320, the
D435 dims baked into task_config/demo_clean.yml). reset() still resolves
the full setup_kwargs lazily — that's fine because reset() is only
called inside the benchmark Docker image where RoboTwin is present.

Also resync the test file with the current env API:
  - mock get_obs() as the real nested {"observation": {cam: {"rgb": …}},
    "joint_action": {"vector": …}} shape
  - patch both _load_robotwin_task and _load_robotwin_setup_kwargs
    (_patch_load → _patch_runtime)
  - drop `front_camera` / `left_wrist` from assertions — aloha-agilex
    exposes head_camera + left_camera + right_camera, not those
  - black-frame test now uses left_camera as the missing camera
  - setup_demo call check loosened to the caller-provided seed/is_test
    bits (full kwargs include the YAML-derived blob)

* fix: integrate PR #3315 review feedback

- ci: add Docker Hub login step, add HF_USER_TOKEN guard on eval step
- docker: tie patches to pinned versions with removal guidance, remove
  unnecessary HF_TOKEN for public dataset, fix hadolint warnings
- docs: fix paper link to arxiv, add teaser image, fix camera names
  (4→3 cameras), fix observation dims (480x640→240x320)


* fix(docs): correct RoboTwin 2.0 paper arxiv link


* fix(docs): use correct RoboTwin 2.0 teaser image URL


* fix(docs): use plain markdown image to fix MDX build

* ci(robotwin): smoke-eval 10 tasks instead of 5

Broader coverage on the RoboTwin 2.0 benchmark CI job: bump the smoke
eval from 5 tasks to 10 (one episode each). Added tasks are all drawn
from ROBOTWIN_TASKS and mirror the shape/complexity of the existing
set (simple single-object or single-fixture manipulations).

Tasks now run: beat_block_hammer, click_bell, handover_block,
open_laptop, stack_blocks_two, click_alarmclock, close_laptop,
close_microwave, open_microwave, place_block.

`parse_eval_metrics.py` reads `overall` for multi-task runs so no
parser change is needed. Bumped the step name and the metrics label
to reflect the 10-task layout.


* fix(ci): swap 4 broken RoboTwin tasks in smoke eval

The smoke eval hit two upstream issues:
- `open_laptop`: bug in OpenMOSS/RoboTwin main — `check_success()` uses
  `self.arm_tag`, but that attribute is only set inside `play_once()`
  (the scripted-expert path). During eval `take_action()` calls
  `check_success()` directly, hitting `AttributeError: 'open_laptop'
  object has no attribute 'arm_tag'`.
- `close_laptop`, `close_microwave`, `place_block`: not present in
  upstream RoboTwin `envs/` at all — our ROBOTWIN_TASKS tuple drifted
  from upstream and these names leaked into CI.

Replace the four broken tasks with upstream-confirmed equivalents
that exist both in ROBOTWIN_TASKS and in RoboTwin's `envs/`:
`adjust_bottle`, `lift_pot`, `stamp_seal`, `turn_switch`.

New 10-task smoke set: beat_block_hammer, click_bell, handover_block,
stack_blocks_two, click_alarmclock, open_microwave, adjust_bottle,
lift_pot, stamp_seal, turn_switch.


* fix(robotwin): sync ROBOTWIN_TASKS + doc with upstream (50 tasks)

The local ROBOTWIN_TASKS tuple drifted from upstream
RoboTwin-Platform/RoboTwin. Users passing names like `close_laptop`,
`close_microwave`, `dump_bin`, `place_block`, `pour_water`,
`fold_cloth`, etc. got past our validator (the names were in the
tuple) but then crashed inside robosuite with a confusing error,
because those tasks don't exist in upstream `envs/`.

- Replace ROBOTWIN_TASKS with a verbatim mirror of upstream's
  `envs/` directory: 50 tasks as of main (was 60 with many
  stale entries). Added a `gh api`-based one-liner comment so
  future bumps are mechanical.
- Update the `60 tasks` claims in robotwin.mdx and
  RoboTwinEnvConfig's docstring to `50`.
- Replace the stale example-task table in robotwin.mdx with ten
  upstream-confirmed examples, and flag `open_laptop` as
  temporarily broken (its `check_success()` uses `self.arm_tag`
  which is only set inside `play_once()`; eval-mode callers hit
  AttributeError).
- Rebuild the "Full benchmark" command with the actual 50-task
  list, omitting `open_laptop`.


* test(robotwin): lower task-count floor from 60 to 50

ROBOTWIN_TASKS was trimmed to 50 tasks (see comment in
`src/lerobot/envs/robotwin.py:48`), but the assertion still
required ≥60, causing CI failures. Align the test with the
current upstream task count.


* fix(envs): preserve AsyncVectorEnv metadata/unwrapped in lazy eval envs

Port of #3416 onto this branch.

* ci: gate Docker Hub login on secret availability


* fix: integrate PR #3315 review feedback

- envs(robotwin): default `observation_height/width` in
  `create_robotwin_envs` to `DEFAULT_CAMERA_H/W` (240/320) so they
  match the D435 dims baked into `task_config/demo_clean.yml`.
- envs(robotwin): resolve `task_config/demo_clean.yml` via
  `CONFIGS_PATH` instead of a cwd-relative path; works regardless
  of where `lerobot-eval` is invoked.
- envs(robotwin): replace `print()` calls in `create_robotwin_envs`
  with `logger.info(...)` (module-level `logger = logging.getLogger`).
- envs(robotwin): use `_LazyAsyncVectorEnv` for the async path so
  async workers start lazily (matches LIBERO / RoboCasa / VLABench).
- envs(robotwin): cast `agent_pos` space + joint-state output to
  float32 end-to-end (was mixed float64/float32).
- envs(configs): use the existing `_make_vec_env_cls(use_async,
  n_envs)` helper in `RoboTwinEnvConfig.create_envs`; drop the
  `get_env_processors` override so RoboTwin uses the identity
  processor inherited from `EnvConfig`.
- processor: delete `RoboTwinProcessorStep` — the float32 cast now
  happens in the wrapper itself, so the processor is redundant.
- tests: drop the `TestRoboTwinProcessorStep` suite; update the
  mock obs fixture to use float32 `joint_action.vector`.
- ci: hoist `ROBOTWIN_POLICY` and `ROBOTWIN_TASKS` to job-level
  env vars so the task list and policy aren't duplicated across
  eval / extract / parse steps.
- docker: pin RoboTwin + CuRobo upstream clones to commit SHAs
  (`RoboTwin@0aeea2d6`, `curobo@ca941586`) for reproducibility.

* fix(docker): use uv pip to install robocasa in benchmark image

The huggingface/lerobot-gpu base image uses `uv` with a venv at
/lerobot/.venv — `pip` is not on PATH, so `pip install` fails with
"pip: not found". Switch to `uv pip install` which installs into the
existing venv.

Also drop the @v1.0.0 tag pin from the robocasa git URL since the
upstream repo may not have that tag; use default branch instead.

* fix(robocasa): editable install + switch to lerobot/smolvla_robocasa

- pip install from git omits data files like box_links_assets.json
  (not declared in package_data). Clone and install editable so the
  source tree is used at runtime.
- Download only tex + fixtures_lw asset types (smoke test doesn't need
  objaverse/aigen objects). Pipe 'y' to auto-accept download prompt.
- Switch CI policy from pepijn223/smolvla_robocasa to lerobot/smolvla_robocasa.

* fix(docker): re-install lerobot editably after COPY

The nightly huggingface/lerobot-gpu image predates the RoboCasaEnv
registration — so `lerobot-eval --env.type=robocasa` fails at argparse
with "invalid choice" even after COPY . . overlays the new source.
Force an editable reinstall so the venv picks up the current configs.py.


* fix(ci): add rename_map for robocasa eval (image* -> camera*)

Policy lerobot/smolvla_robocasa expects observation.images.camera1/2/3,
but RoboCasaEnv produces observation.images.image/image2/image3.

* fix(robocasa): override RoboCasaGymEnv default split (test -> all)

RoboCasaGymEnv defaults split="test", but create_env only accepts
{None, "all", "pretrain", "target"}, so the out-of-the-box default
crashes with ValueError. Always pass "all" when split is None.


* fix(docker): also download objs_lw (lightwheel objects) for robocasa

Kitchen tasks (e.g. CloseFridge) reference lightwheel object meshes
like Stool022/model.xml. fixtures_lw alone isn't enough — we also
need objs_lw. Still skipping objaverse/aigen to keep image size down.

Made-with: Cursor

* feat(robocasa): raw camera names + benchmark-group task shortcuts

Align the LeRobot env with RoboCasa's native conventions so policies
trained on the upstream datasets don't need a --rename_map at eval
time, and expose the standard task groups as first-class --env.task
values.

- Preserve raw RoboCasa camera names (e.g. robot0_agentview_left)
  as observation.images.<name> end-to-end. Drops camera_name_mapping
  and DEFAULT_CAMERA_NAME_MAPPING; features/features_map are now
  built dynamically from the parsed camera list.
- Accept benchmark-group names as --env.task: atomic_seen,
  composite_seen, composite_unseen, pretrain50/100/200/300. Expanded
  lazily via robocasa.utils.dataset_registry and auto-sets the
  split ("target" | "pretrain").
- Update CI smoke-eval rename_map to map raw cam names to the
  camera1/2/3 keys expected by lerobot/smolvla_robocasa.


* docs(robocasa): single-task smolvla train+eval recipe on pepijn223/robocasa_CloseFridge

- Rewrite observation section to use raw RoboCasa camera keys
  (observation.images.robot0_agentview_{left,right},
  observation.images.robot0_eye_in_hand).
- Add a "Training on a single task" section with a full smolvla
  training command on pepijn223/robocasa_CloseFridge, plus matching
  single-task eval command.
- Document benchmark-group task shortcuts (atomic_seen, composite_seen,
  composite_unseen, pretrain50/100/200/300) as valid --env.task values.


* fix(robocasa): restrict obj_registries to lightwheel by default

CloseFridge (and most kitchen tasks) crashed at reset with
`ValueError: Probabilities contain NaN` coming out of
`sample_kitchen_object_helper`. RoboCasa's upstream default
`obj_registries=("objaverse", "lightwheel")` normalizes per-registry
candidate counts as probabilities; when a sampled category has zero
mjcf paths in every configured registry (because the objaverse asset
pack isn't on disk — ~30GB, skipped by our Docker build), the 0/0
divide yields NaNs and `rng.choice` raises.

- Add `obj_registries: list[str] = ["lightwheel"]` to `RoboCasaEnv`
  config; thread it through `create_robocasa_envs`, `_make_env_fns`,
  and the gym.Env wrapper to the underlying `RoboCasaGymEnv` (which
  forwards to `create_env` → `robosuite.make` → kitchen env).
- Default matches what `download_kitchen_assets --type objs_lw`
  actually ships, so the env works out of the box without a 30GB
  objaverse download.
- Document the override (`--env.obj_registries='[objaverse,lightwheel]'`)
  for users who have downloaded the full asset set.


* fix(docker): also download tex_generative for robocasa benchmark

RoboCasa's lightwheel kitchen fixtures embed references to
`generative_textures/wall/tex*.png` directly in their MuJoCo XML, so
`MjModel.from_xml_string` errors out at reset time with
"No such file or directory" even when the env is constructed with
`generative_textures=None`. The generative textures live under a
separate asset registry key (`tex_generative`) in
`download_kitchen_assets`, distinct from the base `tex` pack we were
already fetching.

- Add `tex_generative` to the download list so the fixture XMLs
  resolve.
- Document the remaining omissions (objaverse/aigen, ~30GB) and how
  the runtime side pairs this with obj_registries=["lightwheel"] to
  avoid sampling from categories whose assets aren't on disk.

* ci(robocasa): smoke-eval 10 atomic tasks instead of 1

Broader coverage in the benchmark CI job: evaluate SmolVLA on ten
fixture-centric atomic RoboCasa tasks (one episode each) instead of
just CloseFridge. The tasks are all drawn from TARGET_TASKS.atomic_seen
and selected to avoid object-manipulation categories that would require
the objaverse/aigen asset packs (we only ship objs_lw in the Docker
image, paired with obj_registries=["lightwheel"] on the runtime side).

Tasks: CloseFridge, OpenCabinet, OpenDrawer, TurnOnMicrowave,
TurnOffStove, CloseToasterOvenDoor, SlideDishwasherRack,
TurnOnSinkFaucet, NavigateKitchen, TurnOnElectricKettle.

`scripts/ci/parse_eval_metrics.py` already handles multi-task output
via the `overall` key, so no parser changes needed. Bumped the metrics
artifact's task label to `atomic_smoke_10` to reflect the grouping.

* fix(pyproject): drop unresolvable robocasa extra

robocasa's upstream setup.py hardcodes `lerobot==0.3.3` in
install_requires. Exposing it as the `lerobot[robocasa]` extra made
uv's dep resolver cycle: `lerobot[robocasa]` -> robocasa -> lerobot
(a different version) -> unsolvable. This broke every `uv sync` — even
invocations with an unrelated extra like `--extra test` — because uv
validates the whole lockfile graph.

- Remove the `robocasa` extra from pyproject.toml. Installation
  instructions in docs/source/robocasa.mdx now walk users through the
  manual `git clone` + `pip install --no-deps` flow, which matches
  what the Docker image already does and sidesteps the cyclic dep
  entirely.
- Dockerfile: `uv pip install -e ~/robocasa --no-deps` so the
  shadowed lerobot==0.3.3 never lands in the image; install
  robocasa's actual runtime deps (numpy, numba, scipy, mujoco,
  tianshou, etc.) explicitly.

* docs(robocasa): align page with adding_benchmarks template

Rework docs/source/robocasa.mdx to follow the standard benchmark doc
structure: intro + links + available tasks (with family breakdown and
first-class benchmark-group shortcuts) + installation + eval +
recommended episodes + policy I/O + training + reproducing results.

- Fix the paper link (was pointing at a non-existent arxiv ID).
- Surface lerobot/smolvla_robocasa and pepijn223/robocasa_CloseFridge
  in the top-of-page links so they're findable without reading the
  training section.
- Add an explicit "Object registries" subsection explaining the
  `--env.obj_registries=[objaverse,lightwheel]` override path.
- Add an explicit "Reproducing published results" section pointing
  at the CI smoke eval.

* fix: integrate PR #3375 review feedback

- envs(robocasa): hoist the duplicated `_parse_camera_names` helper
  out of `libero.py` and `robocasa.py` into `envs/utils.py` as the
  public `parse_camera_names`; call sites updated.
- envs(robocasa): give each factory a distinct `episode_index`
  (`0..n_envs-1`) and derive a per-worker seed series in `reset()`
  so n_envs workers don't all roll the same scene under a shared
  outer seed.
- envs(robocasa): drop the unused `**kwargs` on `_make_env`; declare
  `visualization_height` / `visualization_width` on both the wrapper
  and the `RoboCasaEnv` config + propagate via `gym_kwargs`.
- envs(robocasa): emit `info["final_info"]` on termination (matching
  MetaWorld) so downstream vector-env auto-reset keeps the terminal
  task/success flags.
- docs(robocasa): add `--rename_map` (robot0_agentview_left/
  eye_in_hand/agentview_right → camera1/2/3) plus CI-parity flags to
  all three eval snippets.
- docker(robocasa): pin robocasa + robosuite git SHAs and the pip
  dep versions (pygame, Pillow, opencv-python, pyyaml, pynput, tqdm,
  termcolor, imageio, h5py, lxml, hidapi, gymnasium) for
  reproducible benchmark images.
- ci(robocasa): update the workflow comment — there is no
  `lerobot[robocasa]` extra; robocasa/robosuite are installed
  manually because upstream's `lerobot==0.3.3` pin shadows ours.

* docs(robocasa): add benchmark banner image

* fix(envs): preserve AsyncVectorEnv metadata/unwrapped in lazy eval envs

Port of #3416 onto this branch. Also threads the cached metadata
through the RoboCasa factory so async eval on `--env.type=robocasa`
keeps the same improvement.


* fix: integrate PR #3375 review feedback (round 2)

- envs(robocasa): when the caller passes `seed=None` to `reset()`,
  fall back to `self.episode_index` for the inner env seed so each
  worker still samples a distinct trajectory instead of all workers
  inheriting the same global RNG state.
- envs(robocasa): replace the two module-level `print()` calls in
  `create_robocasa_envs` with `logger.info(...)` via a module-level
  `logger = logging.getLogger(__name__)`.
- ci(robocasa): run `scripts/ci/extract_task_descriptions.py` after
  the eval so `metrics.json` carries per-task natural-language
  labels, matching LIBERO / MetaWorld / VLABench jobs. Added a
  `_robocasa_descriptions()` extractor that splits CamelCase task
  names into word-level labels keyed by `<task>_0`.
