# LeRobot
**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.

### Recommended evaluation episodes
For reproducible benchmarking, use **10 episodes per task** across all four standard suites (Spatial, Object, Goal, Long). This gives 400 total episodes and matches the protocol used for published results. Success rates may vary by a few percent across evaluation seeds, so we recommend averaging over 3 seeds.
<Tip>
To compare two policies on the same episodes, use the same `--seed`, keep
`--env.init_states=true`, and run each task in a single batch

We provide a preprocessed LIBERO dataset fully compatible with LeRobot:

Train SmolVLA on the recommended dataset:
```bash

--policy.repo_id=${HF_USER}/libero-test \
--policy.load_vlm_weights=true \

```
To share the result on the Hub, replace `--policy.push_to_hub=false` with `--policy.repo_id=${HF_USER}/libero-smolvla`. Evaluate saved checkpoints with `lerobot-eval` as shown in the [Evaluation](#evaluation) section.

We reproduce the results of Pi0.5 on the LIBERO benchmark. 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).

### Quickstart on LIBERO
Finetune the LIBERO base model on [lerobot/libero](https://huggingface.co/datasets/lerobot/libero), a ~1.9 GB video-encoded copy of the demonstrations behind the [results below](#libero-benchmark-results).
It carries the keys π₀.₅ reads, which are also the ones the LIBERO environment produces at evaluation time:
| Feature | Shape in the dataset | How π₀.₅ consumes it |
| --------------------------- | -------------------- | ------------------------------------------------------- |
| `observation.images.image` | 256×256×3, agentview | resized to 224×224 |
| `observation.images.image2` | 256×256×3, wrist | resized to 224×224 |
| `observation.state` | 8 | discretized into 256 bins and written into the prompt |
| `action` | 7 | padded to 32 internally; the loss uses the first 7 dims |
**No `--rename_map` is needed here** — the keys already match; see [Rename Map and Empty Cameras](./rename_map) if yours differ.
<Tip>
π₀.₅ uses the gated

tokenizer — accept its license on the Hub and log in with `hf auth login`
before training.

Sized for a single 80 GB GPU:
```bash

--dataset.repo_id=lerobot/libero \

--policy.normalization_mapping='{"ACTION": "MEAN_STD", "STATE": "MEAN_STD", "VISUAL": "IDENTITY"}' \

```
**Mean/std normalization, not π₀.₅'s [quantile default](#quantile-statistics)** — matching [pi05_libero_finetuned_v044](https://huggingface.co/lerobot/pi05_libero_finetuned_v044), the checkpoint the results below were measured on.
**`--policy.n_action_steps=10` and `--policy.empty_cameras=1` are explicit** because `--policy.pretrained_path` loads weights only — `lerobot/pi05_libero_base` stores both, and they would otherwise fall back to `50` and `0` (see [Loading a checkpoint](#loading-a-checkpoint)).
Then evaluate a checkpoint with `lerobot-eval` and compare against the reference success rates — see [LIBERO](./libero).
### Quantile statistics
π₀.₅ normalizes `STATE` and `ACTION` with quantiles, so your dataset's `meta/stats.json` needs `q01` and `q99`. Older datasets carry only `min`/`max`/`mean`/`std` and fail on the first batch:
```
ValueError: QUANTILES normalization mode requires q01 and q99 stats
```
Recompute them:
```bash
lerobot-edit-dataset \
--repo_id your_dataset \
--new_repo_id your_dataset \
--operation.type recompute_stats \
--operation.overwrite true
```
**The result lands in `$HF_LEROBOT_HOME/your_dataset`**, not the cache `--dataset.repo_id` reads — so train with `--dataset.root=$HF_LEROBOT_HOME/your_dataset`, or add `--push_to_hub true` above.
Or keep the dataset as-is and pass `--policy.normalization_mapping='{"ACTION": "MEAN_STD", "STATE": "MEAN_STD", "VISUAL": "IDENTITY"}'`.

@@ -159,24 +74,10 @@ lerobot-train \
- **`--policy.compile_model=true`**: Enables model compilation for faster training
- **`--policy.gradient_checkpointing=true`**: Reduces memory usage significantly during training
- **`--policy.dtype=bfloat16`**: Use mixed precision training for efficiency
- **`--batch_size=64`**: Batch size for training, adapt this based on your GPU memory
- **`--batch_size=32`**: Batch size for training, adapt this based on your GPU memory
- **`--policy.pretrained_path=lerobot/pi05_base`**: The base π₀.₅ model you want to finetune, options are:
- [lerobot/pi05_base](https://huggingface.co/lerobot/pi05_base)
- [lerobot/pi05_libero_base](https://huggingface.co/lerobot/pi05_libero_base) (specifically trained on the Libero dataset)
### Loading a checkpoint
The two forms are not interchangeable:
| | `--policy.path` | `--policy.pretrained_path` |
| -------------------------------------- | ---------------------------------------------- | ------------------------------------ |
| Loads | weights **and** the checkpoint's `config.json` | weights only |
| Feature names | from the checkpoint | from your dataset |
| Stored settings, e.g. `n_action_steps` | inherited | reset to the defaults |
| `--policy.type` | must be omitted | required |
| `--rename_map` | needed when your camera keys differ | never — the keys come from your data |
Passing a `--rename_map` alongside `--policy.pretrained_path` renames the batch away from those names, and the first batch fails with `All image features are missing from the batch`.

### Training Parameters Explained
@@ -187,6 +88,15 @@ Passing a `--rename_map` alongside `--policy.pretrained_path` renames the batch
**💡 Tip**: Setting `train_expert_only=true` freezes the VLM and trains only the action expert and projections, allowing finetuning with reduced memory usage.
If your dataset is not converted with `quantiles`, you can convert it with the following command:
```bash
python src/lerobot/scripts/augment_dataset_quantile_stats.py \
--repo-id=your_dataset \
```
Or train pi05 with this normalization mapping: `--policy.normalization_mapping='{"ACTION": "MEAN_STD", "STATE": "MEAN_STD", "VISUAL": "IDENTITY"}'`
## Relative Actions
By default, π₀.₅ predicts absolute actions. You can enable **relative actions** so the model predicts offsets relative to the current robot state. This can improve training stability for certain setups.
