Pepijn babc85b553 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.

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

# 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.

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

# 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:

# 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:

# 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)

docker run -it --device=/dev/ -v /dev/:/dev/ --rm huggingface/lerobot-cpu:latest
