 ## 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.
- **Imports**: prefer top-level imports; relative (`from .sibling import X`) across sibling files within a module, absolute (`from lerobot.module import X`) across modules.
- **Optional dependencies**: many policies, envs, and robots are behind extras (e.g., `lerobot[aloha]`, see `pyproject.toml`). Guard optional imports with `TYPE_CHECKING or _foo_available` at module top + a `require_package(...)` check at use time. Reuse the `_foo_available` flags in `utils/import_utils.py`; don't call `is_package_available`.
+- **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`).

After the initial reply to your report, the security team will keep you informed of the progress towards a fix and full announcement, and may ask for additional information or guidance.
-
-## Recognition
-
-We do not offer a monetary bounty. For a valid, in-scope report we credit you on the published GitHub Security Advisory and name you as the reporter in the associated CVE. Let us know how you'd like to be credited (name or handle).
-
-## What your report must include
-
-We receive a high volume of reports. To be triaged, a report **must** follow the structure below. Copy this block into your submission and fill in every field. Reports missing the version, the proof of concept, or the impact are returned as incomplete and are not investigated until provided.
-
-```markdown
-### Summary
-
-One sentence: what the vulnerability is and where.
-
-### Affected version / commit
-
-Exact released version or commit SHA you reproduced on (e.g. v4.57.0 / a1b2c3d).
-Not "latest" or "main".
-
-### Affected component
-
-The public API, module, or entry point involved (e.g. `AutoModel.from_pretrained`).
-
-### Vulnerability class
-
-Type and CWE if known (e.g. deserialization / CWE-502, path traversal / CWE-22).
-
-### Attack vector & preconditions
-
- How is the vulnerable code reached? (which API call / input / config)
- Who is the attacker and what do they control?
- What must be true for the attack to work? (auth, a user action, a non-default
-  setting, a malicious file being loaded, etc.)
-
-### Proof of concept
-
-A minimal, self-contained script or step sequence that runs on a clean install
-of the version above. Include:
-
- the exact commands / code to run,
- any input files needed (attach them, or give a script that generates them),
- the **expected** behavior vs. the **actual** behavior you observed.
-  A snippet showing that a function _exists_ or _could_ be misused is not a PoC.
-
-### Impact
-
-What an attacker gains in a realistic deployment. "Could theoretically…"
-without a working chain is not an impact.
-
-### Scope
-
-Which trust boundary (see below) does this cross? If your finding touches
-anything in the "Out of scope" list, name which item and explain why it is
-nonetheless a violation of a guarantee we make.
-
-### Suggested severity (optional)
-
-We assign the final severity. Include a CVSS v3.1 vector only if you have one.
-
-### Suggested fix (optional)
-```
-
-> [!NOTE]
-> The bar is a **reproducible PoC against a supported version, with a concrete impact that crosses a trust boundary we actually defend** (see scope below). Reports that are theoretical, auto-generated by a scanner or LLM, or that restate documented behavior will be closed without detailed review.

-## Threat model & trust boundaries
-
-`lerobot` is tightly coupled to the Hugging Face Hub for sharing data and pretrained policies. When downloading artifacts uploaded by others, you expose yourself to risks. Please read below for recommendations to keep your runtime and robot environment safe. We _will_ treat as a vulnerability anything that breaks one of these protections — e.g. code executing despite `safetensors`-only loading, or a pinned revision being bypassed.
+`lerobot` is tightly coupled to the Hugging Face Hub for sharing data and pretrained policies. When downloading artifacts uploaded by others, you expose yourself to risks. Please read below for recommendations to keep your runtime and robot environment safe.

 ### Remote Artefacts (Weights & Policies)

-Models and policies uploaded to the Hugging Face Hub come in different formats. We heavily recommend uploading and downloading models in the [`safetensors`](https://github.com/huggingface/safetensors) format. `safetensors` was developed specifically to prevent arbitrary code execution on your system, which is critical when running software on physical hardware/robots. To avoid loading models from unsafe formats (e.g., `pickle`), you should ensure you are prioritizing `safetensors` files.

 ### Remote Code

-Some models or environments on the Hub may require `trust_remote_code=True` to run custom architecture code. Please **always** verify the content of the modeling files when using this argument. We recommend setting a specific `revision` (commit hash) when loading remote code to ensure you protect yourself from unverified updates to the repository.
+Some models or environments on the Hub may require `trust_remote_code=True` to run custom architecture code.

-## In scope
-
-We treat as vulnerabilities issues in the **published package code** — the library's own API surface — that an attacker can trigger without the victim having opted into a documented risk. For example:
-
- code execution, memory corruption, or file access reachable through a normal API call on input that is **not** an untrusted model/artifact the user chose to load;
- a control we advertise being bypassed (e.g. code running despite `safetensors`-only loading, or a pinned revision being ignored);
- exposure or mishandling of credentials, tokens, or another user's data by the library;
- a real escape from a backend we document as a sandbox;
- CI/CD or supply-chain issues in this repository.
-
-## Out of scope
-
-The following are **not** treated as vulnerabilities in `lerobot`. If your finding touches one of these, the report must explain why it is nonetheless a violation of a guarantee we make — otherwise it will be closed.
-
- Issues that require loading an untrusted artifact and amount to the documented load-time risk above (code execution / file access on load of a malicious model, dataset, config, or pickle).
- Findings in `examples/`, documentation, tests, or other non-packaged reference material.
- Local denial-of-service from feeding pathological input to a function on your own machine (high memory, slow parse, panic), absent a multi-tenant or remote-service impact.
- Model behavior: jailbreaks, alignment failures, prompt injection, or harmful generations. Model weights are authored by their uploaders; report these to the model owner.
- Vulnerabilities in third-party dependencies we do not vendor — report upstream (we'll bump once fixed).
- Theoretical issues without a working proof of concept, and reports auto-generated from scanners or LLMs without a verified, reproducible chain.
- Best-practice or hardening suggestions with no demonstrated impact — missing email-authentication or transport records (MTA-STS, TLS-RPT, DMARC/SPF tuning), missing HTTP security headers, TLS configuration preferences, and similar scanner or config-checker output presented without a working exploit chain.
-
-## Safe harbor
-
-Good-faith research that respects these guidelines, avoids privacy violations and service disruption, and gives us a reasonable disclosure window will not be pursued by us. Do not access data that isn't yours and do not run tests against Hugging Face production infrastructure.

+Resume is twofold and free: (1) each worker skips any sub-dataset already present in the
+destination repo (``already_done``), and (2) datatrove skips ranks whose completion marker
+exists. Re-run the identical command to mop up failures.
+
+Example (numeric smoke test on one namespace, no SLURM):
+    python slurm_migrate.py --slurm 0 --workers 1 \
+        --dst-repo HuggingFaceVLA/community_dataset_v3_degrees \
+        --work-dir ./cdv3_work --manifest-dir ./cdv3_manifests \
+        --folder-name Beegbrain
+
+Full run on the cluster:
+    python slurm_migrate.py \
+        --dst-repo HuggingFaceVLA/community_dataset_v3_degrees \
+        --work-dir /fsx/$USER/cdv3_work \
+        --manifest-dir /fsx/$USER/cdv3_manifests \
+        --logs-dir /fsx/$USER/logs/cdv3_migrate \
+        --workers 64 --partition hopper-cpu --qos normal \
+        --cpus-per-task 4 --mem-per-cpu 4G \
+        --env-command "source /fsx/$USER/venvs/lerobot/bin/activate; export HF_TOKEN=<token>"
+
+IMPORTANT: workers must reach the internet (HF download + upload) and have a write-scoped
+HF token (HF_TOKEN) in --env-command. Keep --workers modest (many concurrent commits to one
+destination repo contend); rely on resume passes to clear transient upload failures.

 ## Running on Hugging Face Jobs

-Annotating a real dataset needs a GPU big enough to serve the VLM, so
-`lerobot-annotate` can dispatch itself to
-[Hugging Face Jobs](https://huggingface.co/docs/hub/en/jobs) — same as
-`lerobot-train`. Add `--job.target=<flavor>` to the exact command you'd
-run locally and it runs on that hardware instead:
+Annotation runs on [Hugging Face Jobs](https://huggingface.co/docs/hub/en/jobs).
+The repo ships a launcher script you copy and tweak for your dataset:

 ```bash
-hf auth login   # once
-
-uv run lerobot-annotate \
-    --repo_id=user/my_dataset \
-    --new_repo_id=user/my_dataset_annotated \
-    --push_to_hub=true \
-    --vlm.model_id=Qwen/Qwen3.6-27B \
-    --vlm.num_gpus=1 \
-    --vlm.serve_command="vllm serve Qwen/Qwen3.6-27B --tensor-parallel-size 1 \
-        --max-model-len 32768 --gpu-memory-utilization 0.8 \
-        --uvicorn-log-level warning --port {port}" \
-    --vlm.serve_ready_timeout_s=1800 \
-    --vlm.chat_template_kwargs='{"enable_thinking": false}' \
-    --job.target=h200
+HF_TOKEN=hf_... uv run python examples/annotations/run_hf_job.py
 ```

-That submits a single-GPU `h200` job that:
+[`run_hf_job.py`](https://github.com/huggingface/lerobot/blob/main/examples/annotations/run_hf_job.py)
+starts a single-GPU `h200` job (bump it to `h200x4` for big datasets)
+that:

-1. starts from the `vllm/vllm-openai` image and installs `lerobot` on top,
-2. boots one vLLM server per GPU and drives it over the OpenAI-compatible API,
-3. runs the `plan` / `interjections` / `vqa` modules across the dataset,
+1. installs `lerobot` (from `main`) plus the annotation extras,
+2. boots one vLLM server per GPU (using the `vllm/vllm-openai` image) and
+   drives it over the OpenAI-compatible API,
+3. runs the `plan` / `interjections` / `vqa` modules across the dataset
+   with `lerobot-annotate`,
 4. with `--push_to_hub=true`, uploads the result to `--new_repo_id` (or
   back to `--repo_id` in place if you leave that unset).

-The command streams the job's logs; `Ctrl-C` detaches without cancelling
-it. List the available flavors and their pricing with `hf jobs hardware`.
-
-<Tip warning={true}>
-
-Qwen3.6 ships with thinking enabled, which eats the token budget the
-annotator needs for its JSON answer — `--vlm.chat_template_kwargs='{"enable_thinking": false}'`
-turns it off. Without `--push_to_hub=true` the annotated dataset is
-discarded when the pod exits.

-| `--job.target`      | `local`                   | HF Jobs flavor to run on (e.g. `h200`, `h200x4`). Omitted/`local` runs here.    |
-| `--job.image`       | `vllm/vllm-openai:latest` | Runtime image for the pod.                                                      |
-| `--job.timeout`     | `2h`                      | Wall-clock cap. Raise it for large datasets.                                    |
-| `--job.detach`      | `false`                   | Submit and exit instead of streaming logs.                                      |
-| `--job.lerobot_ref` | `main`                    | Git ref of lerobot installed on the pod — point it at a branch to test changes. |
-| `--job.tags`        | `[]`                      | Extra tags on the job and on any dataset it pushes (`lerobot` is always added). |
-
-For a bigger dataset, scale to `h200x4` and raise
-`--vlm.parallel_servers` / `--vlm.num_gpus` to match, and give the job
-more headroom with e.g. `--job.timeout=8h`.
-
-Remote runs need `--repo_id` (the pod pulls the dataset from the Hub;
-`--root` names a directory only your machine has). A dataset that exists
-only in your local cache is pushed to a **private** repo first.
+To use a different dataset, model, or hub repo, edit the `CMD` block in
+the script. Every flag there maps directly to a `lerobot-annotate` flag
+(run `lerobot-annotate --help` for the full list).

 Batches are flat dictionaries keyed by the constants in [`lerobot.utils.constants`](https://github.com/huggingface/lerobot/blob/main/src/lerobot/utils/constants.py): `OBS_STATE` (`observation.state.<motor>`), `OBS_IMAGES` (`observation.images.<camera>`), `OBS_LANGUAGE`, `ACTION`, etc. Reuse the constants — don't invent new prefixes.

-If your model is large enough to warrant [sharded multi-GPU training](./multi_gpu_training#sharded-training-fsdp), also declare its FSDP wrap units — the repeated block classes sharding operates on:
-
-```python
-class MyPolicy(PreTrainedPolicy):
-    ...
-    _fsdp_wrap_modules = ["MyTransformerBlock"]
-```
-
-With this one declaration, `--parallelism.dp_shard=N` works out of the box for your policy (users can still override it with `--accelerator.fsdp.wrap_modules`). Without any wrap source, sharded runs fail at startup by design.

 ### Processor functions

 LeRobot uses `PolicyProcessorPipeline`s to normalize inputs and de-normalize outputs around your policy. For a concrete reference, see [`processor_act.py`](https://github.com/huggingface/lerobot/blob/main/src/lerobot/policies/act/processor_act.py) or [`processor_diffusion.py`](https://github.com/huggingface/lerobot/blob/main/src/lerobot/policies/diffusion/processor_diffusion.py).

-Pay close attention here: processors are the most common reproducibility pain point. A mismatch in normalization mode (`IDENTITY` vs `MEAN_STD` vs `MIN_MAX` vs `QUANTILES`/`QUANTILE10`) or in which features get normalized will train and eval without erroring, yet silently wreck results. Make sure the modes match how the checkpoint was trained, that the required stats exist (e.g. `QUANTILES` needs `q01`/`q99`), and that the pre- and post-processors stay consistent.

 Mirror an existing policy that's structurally similar to yours; the diff is small.

-Most policies need a heavy backbone (transformers, diffusers, a specific VLM SDK). Wherever one exists, prefer loading it e.g from `transformers` or `diffusers` rather than re-implementing the architecture in-tree.

-### Avoid copying a modeling file — subclass it
-
-If your policy needs to modify a backbone that already exists in `transformers` (custom conditioning, extra inputs, a swapped sub-module), **do not vendor a copy of its `modeling_*.py`**. Instead, subclass the smallest upstream unit and override only what changes. [`pi_gemma.py`](https://github.com/huggingface/lerobot/blob/main/src/lerobot/policies/pi_gemma.py) is the canonical reference: it injects AdaRMS conditioning into PaliGemma/Gemma in ~370 lines by subclassing `GemmaModel`/`PaliGemmaModel` and overriding the decoder-layer forward, instead of forking the ~2,000-line modeling file. Model surgery on a _loaded_ native model is also fine (layer truncation, tokenizer expansion, hidden-state capture — see `evo1/internvl3_embedder.py`, `eo1/modeling_eo1.py`, `groot/groot_n1_7.py` for working examples). Reviewers will ask for this pattern when a PR arrives with a copied modeling file; the only accepted exception is a model that does not exist in `transformers` at all.
-
 ### Benchmarks and a published checkpoint

 A new policy is much easier to review — and far more useful — when it ships with a working checkpoint and at least one number you can reproduce.

 **Pick at least one in-tree benchmark.** LeRobot ships sim benchmarks with per-benchmark Docker images (LIBERO, LIBERO-plus, Meta-World, RoboTwin 2.0, RoboCasa365, RoboCerebra, RoboMME, VLABench and more). Pick the one that matches your policy's modality — VLAs usually go to LIBERO or VLABench; image-only BC to LIBERO or Meta-World. The full list lives under [Benchmarks](./libero) in the docs sidebar.

-**Push the checkpoint & processors** to the Hub under `lerobot/<policy>_<benchmark>` (or your namespace if you don't have write access; a maintainer can mirror it). The easiest way is training with `--policy.repo_id=<namespace>/<repo>` and `--policy.push_to_hub=true`: `lerobot-train` publishes the model, both processors, and a model card at the end of the run. To publish an existing checkpoint after the fact, upload its `pretrained_model/` directory (e.g. `huggingface-cli upload`), or use `lerobot-convert-dcp --push_to_hub=...` for sharded-format checkpoints.

-#### Reference training recipe
-
-The released checkpoint records the complete resolved Stage-2 configuration in
-[`train_config.json`](https://huggingface.co/zuoxingdong/evo1_libero/blob/515921f4a2c1d3f3ad523721eafa26fdf2af315b/train_config.json).
-The measured run used two H100 GPUs with two DDP processes and batch 64 per process, giving global batch 128. Both stages used the same topology. The base VLM came from revision
-`014c0583a0d4bedf29fbe2dbff4f865eb998e171` of `OpenGVLab/InternVL3-1B-hf`.
-The released artifact does not record the exact LeRobot training commit or its original dependency lock,
-so the commands below reproduce the recorded configuration and topology from a current checkout rather
-than reconstructing the software environment bit for bit.
-
-From a LeRobot source checkout, install the locked dependencies and download that exact VLM revision:
-
-```bash
-uv sync --locked --extra training --extra evo1 --extra libero
-VLM_DIR=$(uv run hf download OpenGVLab/InternVL3-1B-hf \
-  --revision=014c0583a0d4bedf29fbe2dbff4f865eb998e171)

 **State-of-the-art machine learning for real-world robotics**

-🤗 LeRobot provides a hardware-agnostic, Python-native interface for controlling real robots - from affordable arms like the SO-ARM101 to full humanoids. Plus the tools to record, store, and share the datasets they generate. Every dataset uses the standardized **LeRobotDataset** format (synchronized video + action/state data) and can be streamed directly from the [Hugging Face Hub](https://huggingface.co/lerobot).
+🤗 LeRobot aims to provide models, datasets, and tools for real-world robotics in PyTorch. The goal is to lower the barrier for entry to robotics so that everyone can contribute and benefit from sharing datasets and pretrained models.

-🤗 On top of that data, LeRobot implements state-of-the-art policies - from lightweight imitation-learning models like ACT to large vision-language-action models like π₀ and SmolVLA - all trainable, shareable, and deployable with the same handful of CLI commands.
+🤗 LeRobot contains state-of-the-art approaches that have been shown to transfer to the real-world with a focus on imitation learning and reinforcement learning.

-The goal: lower the barrier to entry for robotics, so that everyone can contribute to, and benefit from, shared datasets and pretrained models.
+🤗 LeRobot already provides a set of pretrained models, datasets with human collected demonstrations, and simulated environments so that everyone can get started.

-## How It Works
-
-**Teleoperate → Record → Train → Deploy**
-
-1. **Teleoperate** - control the robot yourself (with a leader arm, keyboard, or phone) so it can learn from your movements.
-2. **Record** - each demonstration is saved as a dataset: synchronized camera video plus the actions you took.
-3. **Train** - a policy (the neural network that will control the robot) learns to imitate your demonstrations.
-4. **Deploy** - run the trained policy on the robot and watch it complete the task on its own.

-## Common Problems
-
-Running into issues? A few of the most frequent ones:
-
- **Blurry or unusable camera footage** - lighting matters more than resolution. See the [Cameras](./cameras) guide.
- **Build or install errors** (`cmake`, `ffmpeg`, CUDA) - see the Troubleshooting section of the [Installation guide](./installation#troubleshooting).
- **Not sure which policy fits your GPU** - check the [Compute & Hardware Guide](./hardware_guide).
- **Still stuck?** Ask on [Discord](https://discord.gg/s3KuuzsPFb) - the community (and the LeRobot team) is there to help.

We take the Physical Intelligence LIBERO base model (`pi05_libero`) and finetune for an additional 6k steps in bfloat16, with batch size of 256 on 8 H100 GPUs using the [HuggingFace LIBERO dataset](https://huggingface.co/datasets/HuggingFaceVLA/libero).

-## Launching
+## Training with Multiple GPUs

-Distributed training can be launched through both `torchrun` and `accelerate launch`. Accelerate is used as a plain launcher: it does not manage the training configuration, and every distributed training setting lives in LeRobot's own config system.
+You can launch training in two ways:

-With `torchrun`:
+### Option 1: Without config (specify parameters directly)
+
+You can specify all parameters directly in the command without running `accelerate config`:

 ```bash

+  $(which lerobot-train) \

 ```

-With `accelerate launch` (as a plain launcher):
+**Key accelerate parameters:**
+
+- `--multi_gpu`: Enable multi-GPU training
+- `--num_processes=2`: Number of GPUs to use
+- `--mixed_precision=fp16`: Use fp16 mixed precision (or `bf16` if supported)
+
+### Option 2: Using accelerate config
+
+If you prefer to save your configuration, you can optionally configure accelerate for your hardware setup by running:

 ```bash
+accelerate config
+```
+
+This interactive setup will ask you questions about your training environment (number of GPUs, mixed precision settings, etc.) and saves the configuration for future use. For a simple multi-GPU setup on a single machine, you can use these recommended settings:
+
+- Compute environment: This machine
+- Number of machines: 1
+- Number of processes: (number of GPUs you want to use)
+- GPU ids to use: (leave empty to use all)
+- Mixed precision: fp16 or bf16 (recommended for faster training)
+
+Then launch training with:
+
+```bash
+accelerate launch $(which lerobot-train) \
+  --dataset.repo_id=${HF_USER}/my_dataset \
+  --policy.type=act \
+  --policy.repo_id=${HF_USER}/my_trained_policy \
+  --output_dir=outputs/train/act_multi_gpu \
+  --job_name=act_multi_gpu \
+  --wandb.enable=true
+```
+
+## How It Works
+
+When you launch training with accelerate:
+
+1. **Automatic detection**: LeRobot automatically detects if it's running under accelerate
+2. **Data distribution**: Your batch is automatically split across GPUs
+3. **Gradient synchronization**: Gradients are synchronized across GPUs during backpropagation
+4. **Single process logging**: Only the main process logs to wandb and saves checkpoints
+
+## Learning Rate and Training Steps Scaling
+
+**Important:** LeRobot does **NOT** automatically scale learning rates or training steps based on the number of GPUs. This gives you full control over your training hyperparameters.
+
+### Why No Automatic Scaling?
+
+Many distributed training frameworks automatically scale the learning rate by the number of GPUs (e.g., `lr = base_lr × num_gpus`).
+However, LeRobot keeps the learning rate exactly as you specify it.
+
+### When and How to Scale
+
+If you want to scale your hyperparameters when using multiple GPUs, you should do it manually:
+
+**Learning Rate Scaling:**
+
+```bash
+# Example: 2 GPUs with linear LR scaling
+# Base LR: 1e-4, with 2 GPUs -> 2e-4
 accelerate launch --num_processes=2 $(which lerobot-train) \
-  --dataset.repo_id=${HF_USER}/my_dataset \
-  --policy.type=act \
-  --policy.repo_id=${HF_USER}/my_trained_policy \
-  --output_dir=outputs/train/act_multi_gpu \
-  --job_name=act_multi_gpu \
-  --wandb.enable=true
+  --optimizer.lr=2e-4 \
+  --dataset.repo_id=lerobot/pusht \
+  --policy.type=act
 ```

-With no `--parallelism.*` flags, a multi-process launch runs plain DDP. Multi-node runs use the standard `torchrun --nnodes/--node-rank/--rdzv-endpoint` flags (or `accelerate launch --num_machines/--machine_rank/--main_process_ip`).
+**Training Steps Scaling:**

-> [!WARNING]
-> Accelerate's YAML config files (`accelerate launch --config_file some.yaml`, `accelerate config`) are not supported. They configure the engine through environment variables, bypassing LeRobot's configuration system, so `train_config.json` would no longer describe the settings a run actually used. `lerobot-train` therefore refuses to start when [accelerate environment variables](https://huggingface.co/docs/accelerate/usage_guides/fsdp) are set. Put the settings in `--parallelism.*` / `--accelerator.*` flags instead, or set `LEROBOT_ALLOW_ACCELERATE_ENV=1` to acknowledge the override and proceed anyway.
-
-## Batch semantics, learning rate, and steps
-
-Each of the `dp_replicate × dp_shard` data-parallel workers loads its own `--batch_size` micro-batch every step, so one training step consumes `batch_size × dp_world_size` samples, and `× gradient_accumulation_steps` of those go into each optimizer update:
-
-```
-effective_batch_size = batch_size × dp_world_size × gradient_accumulation_steps
-```
-
-The training banner prints this factorization at startup. `--steps` counts loop steps (micro-batches per worker), not optimizer updates.
-
-Gradient accumulation is a first-class flag:
+Since the effective batch size `bs` increases with multiple GPUs (batch_size × num_gpus), you may want to reduce the number of training steps proportionally:

 ```bash
-torchrun --nproc-per-node=2 $(which lerobot-train) \
-  --batch_size=8 --accelerator.gradient_accumulation.steps=4 ...
+# Example: 2 GPUs with effective batch size 2x larger
+# Original: batch_size=8, steps=100000
+# With 2 GPUs: batch_size=8 (16 in total), steps=50000
+accelerate launch --num_processes=2 $(which lerobot-train) \
+  --batch_size=8 \
+  --steps=50000 \
+  --dataset.repo_id=lerobot/pusht \
+  --policy.type=act
 ```

-**LeRobot does not auto-scale the learning rate or the number of steps** when the effective batch size grows. If you scale out and want equivalent training, please adjust manually, e.g. with 2 GPUs: double `--optimizer.lr` (linear scaling), or halve `--steps`.
+## Training Large Models with FSDP

-## Sharded training (FSDP)
+DDP replicates the full model on every GPU, so a model that doesn't fit on one GPU won't fit under
+DDP either. For large models, use **FSDP** (Fully Sharded Data Parallel), which shards parameters,
+gradients, and optimizer state across GPUs. See the [accelerate FSDP guide](https://huggingface.co/docs/accelerate/usage_guides/fsdp) for background.

-If a model is too large to train with DDP, shard it with FSDP2:
+An example on how to launch LeRobot training with FSDP across 4 GPUs (1 machine):

 ```bash
-torchrun --nproc-per-node=4 $(which lerobot-train) \
+accelerate launch --config_file fsdp.yaml --num_processes=4 $(which lerobot-train) \
  --dataset.repo_id=${HF_USER}/my_dataset \
  --policy.type=<your_policy> \
-  --parallelism.dp_shard=4 \
-  --accelerator.mixed_precision=bf16 \
  --output_dir=outputs/train/my_policy_fsdp
 ```

-`--parallelism.dp_shard=-1` shards over however many processes the launcher started.
+A minimal `fsdp.yaml` (FSDP1; shards params/grads/optimizer — ZeRO-3-equivalent):

-### Wrap units
-
-FSDP shards the model in units (typically the repeated transformer block) and gathers one unit at a time during forward/backward. Policies declare their wrap units via `_fsdp_wrap_modules` on the policy class. For example, ACT declares `["ACTEncoderLayer", "ACTDecoderLayer"]` and FastWAM declares `["MoTLayer"]`. For a policy without a `_fsdp_wrap_modules` declaration, pass one of the flags below. You can specify the module class name explicitly, or use a size-based policy instead:
-
-```bash
--accelerator.fsdp.wrap_modules='["MyTransformerBlock"]'   # explicit class names
--accelerator.fsdp.min_num_params=1000000                  # or: wrap every submodule above 1M params
+```yaml
+compute_environment: LOCAL_MACHINE
+distributed_type: FSDP
+mixed_precision: bf16
+num_machines: 1
+num_processes: 4
+fsdp_config:
+  fsdp_version: 1
+  fsdp_sharding_strategy: FULL_SHARD # params + grads + optimizer (ZeRO-3)
+  fsdp_auto_wrap_policy: TRANSFORMER_BASED_WRAP
+  fsdp_transformer_layer_cls_to_wrap: <YourTransformerBlock> # repeated block class to shard
+  fsdp_use_orig_params: true # required: optimizer is built pre-prepare
+  fsdp_state_dict_type: FULL_STATE_DICT
 ```

-If a policy doesn't declare `_fsdp_wrap_modules` and no `--accelerator.fsdp.wrap_modules` or `--accelerator.fsdp.min_num_params` is passed, the run fails at startup rather than silently wrapping only the root module (which would forfeit all sharding memory savings).
+Set `fsdp_transformer_layer_cls_to_wrap` to your model's repeated transformer-block class so each
+block is sharded as its own unit. `fsdp_use_orig_params: true` is required because LeRobot builds the
+optimizer before `accelerator.prepare()`.

-Other sharding settings:
+### FSDP checkpoints

- `--accelerator.fsdp.reshard_after_forward`: whether to keep each unit's parameters resident after forward.
- `--accelerator.fsdp.cpu_offload`: keeps parameters, gradients and optimizer states on CPU.
- `--accelerator.fsdp.ignored_modules`: a regex of module paths to keep unsharded.
+LeRobot gathers the full state dict across all ranks and the main process writes it as a single
+`model.safetensors`, loadable as usual with `Policy.from_pretrained(...)`. Two things to look out for:

-### HSDP
-
-Hybrid Sharded Data Parallel: parameters, gradients and optimizer states are sharded across `dp_shard` ranks, and that sharding is replicated `dp_replicate` times. Parameter all-gathers and gradient reduce-scatters stay inside a shard group; only the all-reduce that synchronizes the replicas crosses between groups. The two degrees must multiply to the world size:
-
-```bash
-# 16 GPUs = 2 nodes × 8: shard within each node, replicate across nodes
-torchrun --nnodes=2 --nproc-per-node=8 ... $(which lerobot-train) \
-  --parallelism.dp_replicate=2 --parallelism.dp_shard=8 ...
-```
-
-## Checkpoints
-
-Every checkpoint contains a `pretrained_model/` directory and a `training_state/` directory:
-
-```text
-005000/  # the training step at that checkpoint
-├── pretrained_model/
-│   ├── config.json  # policy config

-│   ├── policy_preprocessor.json  # preprocessor config (when the run has a preprocessor)
-│   ├── policy_preprocessor_step_*.safetensors  # state of the stateful preprocessor steps
-│   ├── policy_postprocessor.json  # postprocessor config (when the run has a postprocessor)
-│   └── policy_postprocessor_step_*.safetensors  # state of the stateful postprocessor steps
-└── training_state/
-    ├── training_step.json  # step counter, topology, and batch semantics
-    ├── rng_state.safetensors  # rng states
-    ├── scheduler_state.json  # scheduler state (when the run has a scheduler)
-    ├── optimizer_state.safetensors  # full optimizer state (non-sharded runs)
-    ├── optimizer_param_groups.json  # optimizer param groups (non-sharded runs)
-    └── optimizer_0/  # DCP optimizer shards (sharded runs)
-```
-
-During single-GPU or DDP training, the pipeline serializes each state dict into a single file: `model.safetensors` for the model and `optimizer_state.safetensors` for the optimizer.
-
-During sharded training, the optimizer state is saved as DCP shards under `training_state/optimizer_0/`, and the layout of the model under `pretrained_model/` can be configured through `--checkpoint_format`:
-
-| `--checkpoint_format`     | Weights artifact                             | Use when                                                              |
-| ------------------------- | -------------------------------------------- | --------------------------------------------------------------------- |
-| `safetensors` _(default)_ | single `model.safetensors` only              | you want every checkpoint immediately loadable with `from_pretrained` |
-| `dcp`                     | `pytorch_model_fsdp_0/` shard directory only | gathering the full weights makes saves and resumes too slow           |
-| `safetensors_dcp`         | both                                         | you want fast resume _and_ immediately loadable checkpoints           |
-
-Two things to know about gathered (`safetensors`) checkpoints from sharded runs:
-
- **They store fp32 weights.** Under mixed precision training, FSDP keeps an fp32 master copy, and the checkpoint saves the master copy to make sure training resumes consistently.
- The gather is collective (all ranks participate) but only the main process writes.
-
-### Converting DCP checkpoints
-
-`lerobot-convert-dcp` merges a DCP shard directory into a regular `model.safetensors`, offline and without GPUs:
-
-```bash
-lerobot-convert-dcp --checkpoint_dir=outputs/train/run/checkpoints/005000
-lerobot-convert-dcp --checkpoint_dir=... --delete_dcp=true --push_to_hub=${HF_USER}/my_policy
-```
-
-`--push_to_hub` publishes the converted directory as a model repo.
-
-### Resuming
-
-Resume with `--resume=true --config_path=.../checkpoints/last/pretrained_model/train_config.json`. Resuming from a DCP checkpoint supports resharding the model and optimizer state to the _current_ topology, which means you can resume with a different `dp_replicate/dp_shard` split. The data sampler can always resume at the right epoch and offset, but is only _sample-exact_ when the world size and batch size match the original run (a warning is logged otherwise).
-
-> [!NOTE]
-> FSDP checkpoints written by LeRobot 0.6.x and earlier used a different on-disk layout (a gathered full optimizer state) and **cannot be resumed**.
+- **Checkpoints store fp32 weights.** Under mixed precision (`bf16`/`fp16`) FSDP keeps an fp32 master
+  copy, and the checkpoint saves it (~2× the bf16 size on disk) so training can resume consistently
+  with the fp32 optimizer state; `from_pretrained` casts back to the policy dtype on load. FSDP-specific
+  caveat: an fp32 checkpoint is materialized in full precision on the target device _before_ casting,
+  so loading it for inference on a tight GPU can OOM even when the bf16 model would fit — load on CPU
+  first, or cast `model.safetensors` to the deployment dtype offline.
+- The sharded optimizer state is gathered into a full (world-size-independent) state dict and saved
+  alongside the model in the same `optimizer_state.safetensors` / `optimizer_param_groups.json`
+  format as single-GPU training, so **resume-from-checkpoint is supported** with `--resume=true`.
+  Resume reshards both the model and the optimizer state to the _current_ FSDP topology, so you can
+  resume an FSDP checkpoint on a different number of GPUs. Note that the data sampler is only
+  sample-exact when the world size and batch size match the original run (a warning is logged
+  otherwise); the optimizer/model state itself is unaffected.

 ## Notes

- Checkpoint saves and end-of-training publishes are collective (every rank enters them). Gathered weights, sidecar files and Hub uploads are written by the main process alone.
- Metrics are reduced across ranks before logging: losses are averaged, and `samples/s` reports cluster-wide throughput.
- Learning-rate scheduling is stepped once per training step regardless of the number of processes (`step_scheduler_with_optimizer=False` is baked in).
+- The `--policy.use_amp` flag in `lerobot-train` is only used when **not** running with accelerate. When using accelerate, mixed precision is controlled by accelerate's configuration.
+- Training logs, checkpoints, and hub uploads are only done by the main process to avoid conflicts. Non-main processes have console logging disabled to prevent duplicate output.
+- The effective batch size is `batch_size × num_gpus`. If you use 4 GPUs with `--batch_size=8`, your effective batch size is 32.
+- Learning rate scheduling is handled correctly across multiple processes—LeRobot sets `step_scheduler_with_optimizer=False` to prevent accelerate from adjusting scheduler steps based on the number of processes.
+- When saving or pushing models, LeRobot automatically unwraps the model from accelerate's distributed wrapper to ensure compatibility.
+- WandB integration automatically initializes only on the main process, preventing multiple runs from being created.

-Recording, resuming, and merging aggregate quantiles from per-episode summaries, so `meta/stats.json` ends up holding a conservative envelope (`min` for `q <= 50`, `max` for `q > 50`) rather than whole-dataset quantiles. To estimate the latter, scan every episode with a running histogram:
-
-```bash
-python src/lerobot/scripts/augment_dataset_quantile_stats.py \
-    --repo-id=your_dataset \
-    --overwrite \
-    --skip-images
-```
-
-`--skip-images` keeps the existing image statistics and avoids video decoding when only `STATE`/`ACTION` need recomputing, and `--root` reads a local dataset instead of the Hub. These values are histogram estimates, subject to discretization and rebinning error, so they can differ from the conservative ones — which changes π₀.₅'s normalized targets and therefore its loss scale. Statistics already saved inside an existing checkpoint are not affected.

-The LeRobot ecosystem extends far beyond its officially supported hardware. Thanks to LeRobot's plugin architecture, the community has built integrations for a wide range of robot arms and teleoperation devices — from industrial manipulators to affordable hobbyist platforms, VR headsets, haptic devices, and full arm-plus-teleoperator kits. This page showcases community-maintained integrations you can use for teleoperation, data collection, and policy deployment.

-# Third-Party Cameras & Sensors
-
-The LeRobot ecosystem extends far beyond its natively supported cameras (OpenCV, Intel RealSense, ZMQ, Reachy 2). Thanks to LeRobot's plugin architecture, the community has built drop-in camera and sensor integrations — from depth cameras to vision-based tactile sensors. This page showcases community-maintained camera and sensor integrations you can use for teleoperation, data collection, and policy deployment.
-
-> [!IMPORTANT]
-> These projects are developed and maintained by third parties. Please refer to each repository for installation instructions, hardware requirements, and support.
-
-Drop-in plugins are auto-discovered by package name: LeRobot imports any installed package prefixed with `lerobot_camera_`. Once installed, reference the camera `type` the plugin registers (see its README — it may differ from the package name) directly from any LeRobot command:
-
-```bash
-pip install lerobot_camera_<name>
-
-lerobot-record \
-    --robot.type=so101_follower \
-    --robot.port=/dev/ttyACM0 \
-    --robot.cameras="{ front: {type: <name>, width: 640, height: 480, fps: 30} }" \

-
-Change the natural-language task descriptions attached to episodes. This is useful for fixing typos, standardizing wording, or re-labeling episodes.
-
-> [!WARNING]
-> `modify_tasks` modifies the dataset **in-place** (updating `meta/tasks.parquet`, the `task_index` column in the data files, the `tasks` column in the episode metadata, and `total_tasks` in `meta/info.json`). The `--new_repo_id` and `--new_root` parameters are ignored for this operation.

-**Parameters:**
-
- `new_task`: A single task string used as the default for episodes not otherwise covered.
- `episode_tasks`: Mapping from episode index to task string.
- `task_replacements`: Mapping from existing task strings to their replacements, applied to episodes whose current task matches a key. Every key must be an existing task in the dataset.
-
-The modes can be combined in a single run. Per episode, the task is resolved with the following precedence:
-
-`episode_tasks` > `task_replacements` > `new_task` > original task
-
-At least one of `new_task`, `episode_tasks`, or `task_replacements` must be specified. An episode that ends up with no task raises an error.

 #### Convert to Video

 Convert an image-based dataset to video format, creating a new LeRobotDataset where images are stored as videos. This is useful for reducing storage requirements and improving data loading performance. The new dataset will have the exact same structure as the original, but with images encoded as MP4 videos in the proper LeRobot format.

-# Writing docstrings
-
-LeRobot's API reference is generated directly from the docstrings in `src/lerobot/`. A docstring is not a
-comment — it is the published documentation for that object, and the format below is what the renderer and
-the CI checks parse.
-
-This page is the contract. If you are adding or editing anything public in `src/lerobot/`, follow it.
-
-> [!IMPORTANT]
-> **An undocumented public method is an invisible one.** `[[autodoc]]` silently skips members that have no
-> docstring — no warning, no error, it simply does not appear on the rendered page. Coverage and
-> API-reference completeness are the same problem.
-
-## The format in one example
-
-Google section headers, Hugging Face type formatting. Both, not one or the other.
-
-````python
-def send_action(self, action: RobotAction, rate_hz: float = 30.0) -> RobotAction:
-    """Command the robot to move to a target joint configuration.
-
-    Values are clipped by the configured maximum relative target before reaching the motors, so the
-    returned action may differ from the requested one.
-
-    Args:
-        action (`dict[str, float]`):
-            Target values keyed by motor name, e.g. `{"shoulder_pan.pos": 0.0}`. Keys must match the
-            robot's action features.
-        rate_hz (`float`, *optional*, defaults to `30.0`):
-            Control loop frequency.
-
-    Returns:
-        `dict[str, float]`: The action actually written to the motors after safety clipping.
-
-    Raises:
-        DeviceNotConnectedError: If the robot has not been connected.
-
-    Example:
-        ```python
-        >>> from lerobot.robots.so_follower import SO101Follower, SO101FollowerConfig
-        >>> robot = SO101Follower(SO101FollowerConfig(port="/dev/ttyACM0"))  # doctest: +SKIP
-        >>> robot.connect()  # doctest: +SKIP
-        >>> robot.send_action({"shoulder_pan.pos": 0.0})  # doctest: +SKIP
-        ```
-    """
-````
-
-Cross-references are omitted from the examples on this page — see [Cross-references](#cross-references) for
-their syntax and why they cannot be shown inside a code block.
-
-## Rules
-
-### Sections
-
-`Args:` · `Returns:` · `Raises:` · `Yields:` · `Example:` · `Note:`
-
-In that order. No other section headers. A one-line summary comes first, then an optional free-form
-description, then the sections.
-
-### The `Args:` line is machine-parsed
-
-```
-name (`type`, *optional*, defaults to `X`):
-    Description, indented on its own line.
-```
-
-The `*optional*, defaults to` clause is **checked against the real signature default** by
-`make check-docstrings`. It is not decorative — if you write a default that has drifted from the code, CI
-fails. Omit the clause entirely for required parameters:
-
-```python
-    Args:
-        port (`str`):
-            Serial port the arm is connected to, e.g. `/dev/ttyACM0`.
-        max_relative_target (`float | dict[str, float]`, *optional*):
-            Caps the magnitude of the relative positional target vector. `None` disables clipping.
-        use_degrees (`bool`, *optional*, defaults to `True`):
-            Keep `True` for backward compatibility with existing policies and datasets.
-```
-
-Types go in backticks. Use `*optional*` with no `defaults to` when the default is `None` or is otherwise not
-worth restating.
-
-### `Returns:` is type-first
-
-One indented line, type first, then a colon, then the description:
-
-```python
-    Returns:
-        `dict[str, float]`: The action actually written to the motors after safety clipping.
-```
-
-`Yields:` takes the same shape.
-
-### `**Attributes**:`, never `Attributes:`
-
-doc-builder parses a bare `Attributes:` as a **synonym for `Parameters:`**, so your attributes get rendered
-as constructor arguments. This is silent and wrong. Whenever the attributes differ from the constructor
-parameters, use the bold form with a `--` separator:
-
-```python
-class Robot(abc.ABC):
-    """The base abstract class for all LeRobot-compatible robots.
-
-    **Attributes**:
-        - **config_class** (`type[RobotConfig]`) -- The expected configuration class for this robot.
-        - **name** (`str`) -- The unique robot name used to identify this robot type.
-    """
-```
-
-Note `--`, not `:`.
-
-### Cross-references
-
-Use doc-builder's bracket syntax: a square-bracketed backtick-quoted path. **Sphinx roles (`:pymeth:`,
-`:pyattr:`) are not supported** and render as literal text on the page.
-
-| Want                         | Write                               |
-| ---------------------------- | ----------------------------------- |
-| Class in the main package    | &#91;`Robot`&#93;                   |
-| Method, show the full path   | &#91;`Robot.connect`&#93;           |
-| Method, show the bare name   | &#91;`~Robot.connect`&#93;          |
-| Nested path                  | &#91;`~robots.Robot.connect`&#93;   |
-| Object in another HF library | &#91;`~accelerate.Accelerator`&#93; |
-
-The `~` strips the path from the **link text only**; the link still resolves to the full path.
-
-> [!NOTE]
-> doc-builder resolves this syntax everywhere in a page — including inside fenced code blocks. That is why
-> the docstring examples on this page use plain prose instead of cross-references: a code block containing
-> one would render the resolved link rather than the syntax you need to type. In your own docstrings, use
-> cross-references freely; this restriction only affects documentation _about_ the syntax.
-
-### Callouts
-
-Use GitHub-style blockquotes:
-
-```markdown
-> [!TIP]
-> Call this once at startup — it takes about two seconds.
-
-> [!WARNING]
-> Torque is disabled on disconnect. The arm will drop if it is holding a load.
-```
-
-The `<Tip>` component is legacy per doc-builder; don't add new ones.
-
-### Examples must be fenced
-
-An example lives inside a fenced ` ```python ` block containing `>>> `. The fence is what makes it render
-as a code block, and it is what the doctest preprocessor's regex looks for:
-
-````python
-    Example:
-        ```python
-        >>> from lerobot.robots.so_follower import SO101FollowerConfig
-        >>> cfg = SO101FollowerConfig(port="/dev/ttyACM0")
-        >>> cfg.use_degrees
-        True
-        ```
-````
-
-> [!WARNING]
-> An unfenced `>>>` is still collected — doctest finds prompts anywhere in a docstring. What you lose is the
-> rendering, so it shows up as a wall of prose on the page. Every example needs the fence.
-
-Every example either executes in CI or carries `# doctest: +SKIP`. Anything that touches hardware, a GPU, or
-downloads from the Hub gets `+SKIP`:
-
-````python
-    Example:
-        ```python
-        >>> robot.connect()  # doctest: +SKIP
-        >>> policy = ACTPolicy.from_pretrained("lerobot/act_aloha_sim_transfer_cube_human")  # doctest: +SKIP
-        ```
-````
-
-Add files containing runnable examples to `utils/documentation_tests.txt`.
-
-Put examples on the three to five genuine entry points of a module. Examples on trivial accessors are noise.
-
-## Three patterns you will hit constantly
-
-### Config dataclasses
-
-Configuration fields are historically documented with `#` comments above each field. **doc-builder cannot
-see inline comments** — such a class renders with every field listed and not a single description. Move them
-into an `Args:` block on the class docstring:
-
-```python
-@dataclass
-class SOFollowerConfig:
-    """Configuration for SO-family follower arms.
-
-    Args:
-        port (`str`):
-            Serial port the arm is connected to, e.g. `/dev/ttyACM0`.
-        max_relative_target (`float | dict[str, float]`, *optional*):
-            Caps the magnitude of the relative positional target vector. A scalar applies to all motors;
-            a dict maps motor name to a per-motor cap. `None` disables clipping.
-        use_degrees (`bool`, *optional*, defaults to `True`):
-            Keep `True` for backward compatibility with existing policies and datasets.
-    """
-
-    port: str
-    max_relative_target: float | dict[str, float] | None = None
-    use_degrees: bool = True
-```
-
-> [!IMPORTANT]
-> **doc-builder does not inherit docstrings from base classes.** LeRobot's registered config classes are
-> often thin multiple-inheritance shims:
->
-> ```python
-> @RobotConfig.register_subclass("so101_follower")
-> @dataclass
-> class SOFollowerRobotConfig(RobotConfig, SOFollowerConfig):
->     pass
-> ```
->
-> That class renders **every** field — including the ones it inherits — with no descriptions at all, no
-> matter how well the bases are documented. The `Args:` block must live on the concrete class that
-> `[[autodoc]]` names, and it must cover inherited fields too.
-
-### Base class, then concrete subclass
-
-The abstract base carries the canonical contract. Subclasses document only what deviates — port semantics,
-calibration quirks, motor layout, supported feature keys. Do not copy the base contract into every subclass.
-
-`Robot`, `Teleoperator`, `Camera`, `MotorsBus`, `ProcessorStep`, and `PreTrainedPolicy` all follow this
-shape.
-
-### Module-level aliases
-
-Several public names are aliases rather than distinct classes:
-
-```python
-SO100FollowerConfig = SOFollowerRobotConfig
-SO101FollowerConfig = SOFollowerRobotConfig
-```
-
-`[[autodoc]]` resolves the alias and renders the **canonical** class name, so a `## SO101FollowerConfig`
-heading will show `class lerobot.robots.so_follower.SOFollowerRobotConfig` in the body. Document the
-canonical class once, and mention the aliases in the page's prose rather than giving each alias its own
-autodoc block.
-
-## What not to document
-
- **Private members.** Anything starting with `_` is not part of the public API.
- **The type annotation restated as prose.** `port (`str`): A string.` adds nothing. Say what it is for.
- **Vendored upstream code.** `src/lerobot/policies/molmoact2/molmoact2_hf_model/` is vendored from
-  `transformers` and already carries upstream-style docstrings. Leave it alone — restyling it only creates
-  conflicts on the next sync. It is excluded from the API reference and from the docstring checks.
-
-## How this is enforced
-
-| Check                     | What it catches                                                                                            |
-| ------------------------- | ---------------------------------------------------------------------------------------------------------- |
-| `make check-docstrings`   | An `Args:` entry that doesn't match the signature; a documented default that has drifted from the real one |
-| `make doctest`            | Examples that no longer run                                                                                |
-| `make check-doctest-list` | Stale or unsorted entries in `utils/documentation_tests.txt`                                               |
-| `ruff` (`D` rules)        | Google-convention style violations                                                                         |
-| `interrogate`             | Docstring coverage falling below the current threshold                                                     |
-| doc-builder               | A `[[autodoc]]` path that points at something that doesn't exist — this breaks the docs build              |
-
-Run them together before opening a PR:
-
-```bash
-make check-docstrings && make doctest && pre-commit run --all-files
-```
-
-Then render the page and actually look at it:
-
-```bash
-doc-builder build lerobot docs/source/ --build_dir /tmp/doc-build
-```
-
-## Checklist
-
- [ ] Every public member you touched has a docstring.
- [ ] Every `Args:` entry matches the signature, including the `*optional*, defaults to` clause.
- [ ] `Returns:` is type-first on one indented line.
- [ ] No bare `Attributes:` — use `**Attributes**:` with `--` separators.
- [ ] No Sphinx roles — cross-references use &#91;`~module.Class.method`&#93;.
- [ ] Examples are inside a fenced ` ```python ` block, and either run in CI or carry `# doctest: +SKIP`.
- [ ] Config dataclass fields are in an `Args:` block on the concrete class, not `#` comments.
- [ ] The rendered page has been eyeballed.

Author	SHA1	Message	Date
CarolinePascal	a369f1d1ee	migration: make per-rank resume prefetch resilient to Hub timeouts Retry the destination list_repo_files with backoff (and fall back to an empty resume set) so a single transient huggingface.co read timeout no longer fails an entire SLURM rank and skips its dataset slice.	2026-07-22 18:33:54 +02:00
CarolinePascal	a62c5495ff	migration: add MolmoAct standalone-dataset migration path Add migrate_molmoact.py to migrate the SO-100/101 datasets listed by allenai/MolmoAct2-SO100_101-Dataset (repo ids derived from language_annotations folder names), skipping any already in lerobot/community_dataset_v3. Generalize run_migration.migrate_one/_write_dataset_card with a backward-compatible standalone mode (download a whole standalone repo, provenance -> source repo) and extend slurm_migrate.py with --source molmoact / --reference-repo.	2026-07-22 16:32:19 +02:00
CarolinePascal	e5830704ba	Tag normalized SO datasets during migration + add backfill script Add a 'normalized' card tag for datasets whose SO joints are left in normalized units (uncalibrated -> APPROXIMATE) in run_migration.py, and add tag_normalized.py to backfill the tag on already-migrated datasets.	2026-07-21 16:54:49 +02:00
CarolinePascal	9f1807996b	migration: compact non-contiguous episode indices before v3.0 convert Datasets with deleted episodes (e.g. '*_clean' variants) keep gaps in their episode numbering across data, videos, and metadata. The stock v2.1->v3.0 converter renumbers data/videos by sorted file order (0..N-1) but reads original gapped indices from episodes.jsonl, so it raises 'Number of episodes is not the same'. Add reindex_episodes(): when every source agrees on the same (non-contiguous) episode set, remap it to 0..N-1 everywhere (data files + episode_index/index columns, per-camera videos, episodes.jsonl, episodes_stats.jsonl, info.json) so conversion succeeds. Verified end-to-end on danaaubakirova/svla_so100_task4_v3_clean (gaps {20,37,38,39} -> 0..49).	2026-07-18 18:34:58 +02:00
CarolinePascal	8f1da1b0d8	fix(datasets): enforce monotonic DTS when concatenating videos Clips encoded with B-frames start at a negative DTS, so the concat demuxer can emit a packet whose DTS equals the previous clip's last DTS at a boundary (worst with single-frame clips). The MP4 muxer rejects duplicate/decreasing DTS with [Errno 22]. Nudge colliding packets forward by the minimal amount to keep DTS strictly increasing.	2026-07-17 22:46:15 +02:00
CarolinePascal	7fc9f57303	migration: make prune deletions resilient to transient Hub timeouts Retry each delete_folder up to 3x with backoff and continue past failures instead of aborting the whole run on the first ReadTimeout. Re-running is safe (present set is recomputed, already-deleted datasets drop out).	2026-07-17 21:21:00 +02:00
CarolinePascal	ef81f9a62d	Revert "migration: prefer success over errored row when de-duplicating manifest" This reverts commit `d0f5849989`.	2026-07-17 21:16:02 +02:00
CarolinePascal	d0f5849989	migration: prefer success over errored row when de-duplicating manifest A dataset can appear multiple times across per-rank/resumed manifests (timed out once, then succeeded on retry). keep='last' could keep the stale ERROR row and wrongly flag an already-migrated dataset (e.g. VoicAndrei/so100_kitchen) for deletion. De-dup now prefers a successful attempt over an errored one.	2026-07-17 21:13:33 +02:00
CarolinePascal	34f9f07c6d	migration: add --report to list errored/mislabeled-so/missing together Non-destructive listing of all three categories in one pass, marking with '*' which datasets are absent from the destination repo.	2026-07-17 21:07:19 +02:00
CarolinePascal	ba6cf118cf	migration: add --list-missing to prune_destination.py Report datasets present in the manifest but absent from the destination repo, grouped by their migration action (ERROR/skipped/...), to explain the src-vs-dst count gap. Also de-duplicate manifest rows by root (resumed runs append).	2026-07-17 17:25:59 +02:00
CarolinePascal	84896aa8c8	migration: add prune_destination.py to remove errored / mislabeled-SO datasets Reads the run manifest(s), selects datasets that errored during migration and/or were labelled SO but aren't a real 6-DOF SO arm, intersects with what's actually present in the destination repo, and deletes their folders. Dry-run by default.	2026-07-17 17:16:11 +02:00
CarolinePascal	e0d455ec9f	migration: ditch datasets whose data and camera files disagree on episode count If the data files and any camera's video files (or two cameras) don't have the same number of episodes, skip the dataset up front instead of letting the converter raise 'All cams dont have same number of episodes' mid-run.	2026-07-17 17:00:29 +02:00
CarolinePascal	a6dcb18585	migration: reconcile stale meta episode count to data+video files When the data files and video files agree on episode count N but the metadata lists a different count, rewrite meta/episodes.jsonl, meta/episodes_stats.jsonl and info.json to N before the v2.1->v3.0 converter runs (which otherwise raises 'Number of episodes is not the same'). Only the safe direction is handled: trimming metadata that lists MORE episodes than exist. Non-contiguous data, data/video disagreement, or metadata missing episodes are left untouched.	2026-07-17 16:59:10 +02:00
CarolinePascal	a0ab158a83	migration: honor matching SO joint names, convert leading SO block When the leading joint names match the canonical SO set, treat the dataset as a genuine SO arm and convert those joints to degrees even if extra columns follow (bbox, etc.), passing the trailing non-joint columns through untouched. Encoding detection now looks only at the SO slice so appended columns can't skew it. Only when no leading 6-DOF SO block can be substantiated is the dataset relabeled 'unknown' and migrated structurally.	2026-07-17 16:54:10 +02:00
CarolinePascal	52659bb331	migration: detect mislabeled SO arms and relabel to 'unknown' A robot_type of so100/so101 is treated as wrong when the joint dim isn't a multiple of 6, or (when names are present) the first 6 joints don't match the canonical SO set. Such datasets are migrated structurally to v3.0 with joints left untouched and robot_type relabeled 'unknown', instead of being skipped or degrees-converted on a false assumption.	2026-07-17 16:41:27 +02:00
CarolinePascal	d53557dec4	migration: skip non-standard SO arms instead of relabeling them Only migrate datasets usable right away as a clean 6-DOF joint stack. SO datasets whose action/observation.state dim isn't a multiple of 6 (extra bbox/EE columns appended) are now skipped as out-of-scope, matching the end-effector skip, rather than being relabeled '_nonstandard' and migrated structurally.	2026-07-17 16:31:22 +02:00
CarolinePascal	17f0d8f9dc	migration: suffix non-standard SO arms with _nonstandard instead of 'unknown' Preserve the original robot_type lineage (e.g. so100 -> so100_nonstandard) for arms whose joint dim isn't a multiple of 6, rather than erasing it to 'unknown'. Idempotent: won't re-append the suffix.	2026-07-17 16:14:32 +02:00
CarolinePascal	e1da15d243	migration: ditch end-effector (task-space) datasets Some datasets store task-space end-effector pose (names like ee_x/ee_roll or x/y/z) instead of joint angles; the degrees mapping is meaningless there. Detect via feature names and skip them entirely (no conversion, no upload) rather than migrating a mislabeled arm.	2026-07-17 15:45:48 +02:00
CarolinePascal	3ea347a3d9	migration: add extract_dataset.py to pull a sub-dataset into a standalone repo download_subfolder gains a repo= arg so it can source from any monorepo; the new extract_dataset.py scoped-downloads one sub-dataset and re-uploads it at the root of a new standalone dataset repo.	2026-07-17 15:45:29 +02:00
CarolinePascal	a02a0befd9	migration: match bi_so100_follower via bi_so prefix The manifest robot_type distribution has 'bi_so100_follower', which the trailing underscore in 'bi_so_' missed. Drop it to 'bi_so' to catch all bimanual SO variants (bi_so_follower, bi_so100_follower, ...) with no false positives.	2026-07-17 15:34:32 +02:00
CarolinePascal	2ebc2dc1b4	migration: detect the full SO family incl. bimanual bi_so_follower Broaden SO_PREFIXES to (so100, so101, so_, bi_so_) so bimanual two-arm datasets (robot_type 'bi_so_follower', 12-dim) are recognized as SO and get the degrees conversion, instead of being skipped as non_so. so_ boundary avoids matching stray names like 'sofa'.	2026-07-17 15:33:05 +02:00
CarolinePascal	425470759d	migration: extract is_so_robot_type and encoding_from_bounds helpers Split classify() into reusable pieces: is_so_robot_type() for the robot_type name test, and encoding_from_bounds() as the single source of truth for the degrees_old/degrees_new/normalized/radians decision from per-joint min/max (layout-agnostic, so v2.1 episodes_stats and v3.0 stats.json both feed it).	2026-07-17 15:32:52 +02:00
CarolinePascal	0ec7c912e7	migration: relabel robot_type to 'unknown' when SO name doesn't match structure is_so is decided purely from the robot_type string, so datasets labeled so100/so101 whose joint dim isn't a multiple of 6 carry a provably wrong label. Rewrite meta/info.json robot_type to 'unknown' in that case so the v3.0 output isn't misidentified as an SO arm.	2026-07-17 15:23:21 +02:00
CarolinePascal	9e3dc7c43c	migration: fall back to structural-only when joint dim isn't a multiple of 6 Datasets whose action/state dim is not a multiple of 6 (e.g. 7-dim with an appended EE pose, or 10-dim) are not a plain stack of SO arms, so the degrees mapping doesn't apply. Migrate them structurally instead of aborting the whole dataset with a ValueError.	2026-07-17 14:05:28 +02:00
CarolinePascal	f82713cdb2	migration: scope subfolder download, keep normalized joints as-is - download_subfolder: fetch only the target sub-dataset subtree instead of enumerating the whole community_dataset_v3 monorepo tree (fixes apparent hang) - normalized SO gripper (RANGE_0_100) left in native 0..100 frame, matching degrees_new datasets, instead of remapping to +/-45deg - uncalibrated normalized datasets: skip identity value rewrite, keep normalized units and flag them APPROXIMATE on the dataset card - remove --allow-uncalibrated flag and its CANON_IS_CALIBRATED side effect	2026-07-16 17:30:10 +02:00
