* feat(envs): add RoboCasa365 benchmark integration Add RoboCasa365 (arXiv:2603.04356) as a new simulation benchmark with 365 everyday kitchen manipulation tasks across 2,500 diverse environments. New files: - src/lerobot/envs/robocasa.py: gym.Env wrapper with deferred env creation, flat 12D action / 16D state vectors, 3-camera support - docs/source/robocasa.mdx: user-facing documentation - docker/Dockerfile.benchmark.robocasa: CI benchmark image Modified files: - src/lerobot/envs/configs.py: RoboCasaEnv config (--env.type=robocasa) - pyproject.toml: robocasa optional dependency group - docs/source/_toctree.yml: sidebar entry - .github/workflows/benchmark_tests.yml: integration test job Refs: https://arxiv.org/abs/2603.04356, https://robocasa.ai Related: huggingface/lerobot#321 * 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`.
Generating the documentation
To generate the documentation, you first have to build it. Several packages are necessary to build the doc, you can install them with the following command, at the root of the code repository:
pip install -e . -r docs-requirements.txt
You will also need nodejs. Please refer to their installation page
NOTE
You only need to generate the documentation to inspect it locally (if you're planning changes and want to
check how they look before committing for instance). You don't have to git commit the built documentation.
Building the documentation
Once you have setup the doc-builder and additional packages, you can generate the documentation by
typing the following command:
doc-builder build lerobot docs/source/ --build_dir ~/tmp/test-build
You can adapt the --build_dir to set any temporary folder that you prefer. This command will create it and generate
the MDX files that will be rendered as the documentation on the main website. You can inspect them in your favorite
Markdown editor.
Previewing the documentation
To preview the docs, first install the watchdog module with:
pip install watchdog
Then run the following command:
doc-builder preview lerobot docs/source/
The docs will be viewable at http://localhost:3000. You can also preview the docs once you have opened a PR. You will see a bot add a comment to a link where the documentation with your changes lives.
NOTE
The preview command only works with existing doc files. When you add a completely new file, you need to update _toctree.yml & restart preview command (ctrl-c to stop it & call doc-builder preview ... again).
Adding a new element to the navigation bar
Accepted files are Markdown (.md).
Create a file with its extension and put it in the source directory. You can then link it to the toc-tree by putting
the filename without the extension in the _toctree.yml file.
Renaming section headers and moving sections
It helps to keep the old links working when renaming the section header and/or moving sections from one document to another. This is because the old links are likely to be used in Issues, Forums, and Social media and it'd make for a much more superior user experience if users reading those months later could still easily navigate to the originally intended information.
Therefore, we simply keep a little map of moved sections at the end of the document where the original section was. The key is to preserve the original anchor.
So if you renamed a section from: "Section A" to "Section B", then you can add at the end of the file:
Sections that were moved:
[ <a href="#section-b">Section A</a><a id="section-a"></a> ]
and of course, if you moved it to another file, then:
Sections that were moved:
[ <a href="../new-file#section-b">Section A</a><a id="section-a"></a> ]
Use the relative style to link to the new file so that the versioned docs continue to work.
For an example of a rich moved sections set please see the very end of the transformers Trainer doc.
Adding a new tutorial
Adding a new tutorial or section is done in two steps:
- Add a new file under
./source. This file can either be ReStructuredText (.rst) or Markdown (.md). - Link that file in
./source/_toctree.ymlon the correct toc-tree.
Make sure to put your new file under the proper section. If you have a doubt, feel free to ask in a Github Issue or PR.
Writing source documentation
Values that should be put in code should either be surrounded by backticks: `like so`. Note that argument names
and objects like True, None or any strings should usually be put in code.
Writing a multi-line code block
Multi-line code blocks can be useful for displaying examples. They are done between two lines of three backticks as usual in Markdown:
```
# first line of code
# second line
# etc
```
Adding an image
Due to the rapidly growing repository, it is important to make sure that no files that would significantly weigh down the repository are added. This includes images, videos, and other non-text files. We prefer to leverage a hf.co hosted dataset like
the ones hosted on hf-internal-testing in which to place these files and reference
them by URL. We recommend putting them in the following dataset: huggingface/documentation-images.
If an external contribution, feel free to add the images to your PR and ask a Hugging Face member to migrate your images
to this dataset.
