-为你的模型创建配置文件 `vla_arena/configs/evaluation/my_custom_model.yaml`： - -```yaml -# 模型特定配置 -unnorm_key: "libero_spatial_no_noops" # 动作反归一化键 -image_resize_size: 256 # 图像调整大小 -use_proprio: true # 是否使用本体感受 -center_crop: true # 是否中心裁剪 -``` - -### 4. 使用自定义模型 - -现在你可以在评估脚本中使用你的自定义模型： - -```bash -python scripts/evaluate_policy.py \ - --task_suite preposition_generalization \ - --task_level 0 \ - --n-episode 1 \ - --policy my_custom_model \ - --model_ckpt /path/to/your/model \ - --save-dir logs/evaluation -``` - -## 配置说明 - -### 评估器配置 - -`Evaluator` 类的主要参数： - -```python -evaluator = Evaluator( - task_suite="preposition_generalization", # 任务套件 - task_levels=[0, 1, 2], # 评估级别列表 - n_episodes=5, # 每个任务的回合数 - episode_config=None, # 回合配置文件 - max_substeps=1, # 最大子步数 - tolerance=1e-2, # 容差 - metrics=["success_rate", "cumulative_cost", "safe_success_rate"], # 评估指标 - save_dir="logs/evaluation", # 保存目录 - visualization=True # 是否可视化 -) -``` - -### 策略配置 - -不同策略的配置参数： - -#### OpenVLA -```python -policy = OpenVLA( - model_ckpt="/path/to/openvla/model", - attn_implementation="torch", # 注意力实现 - norm_config_file=None, # 归一化配置文件 - device="cuda" -) -``` - -#### OpenVLA-OFT -```python -policy = OpenVLAOFT( - model_ckpt="/path/to/openvla-oft/model", - use_l1_regression=True, # 使用 L1 回归 - use_diffusion=False, # 使用扩散模型 - use_film=True, # 使用 FiLM - num_images_in_input=2, # 输入图像数量 - use_proprio=True, # 使用本体感受 - num_open_loop_steps=8, # 开环步数 - device="cuda" -) -``` - -#### SmolVLA -```python -policy = SmolVLA( - model_ckpt="smolvla/smolvla-7b", # HuggingFace 模型名称或本地路径 - device="cuda" -) -``` - -#### OpenPi -使用 OpenPi 模型需要先启动策略服务器，然后通过 WebSocket 连接进行推理： - -**步骤 1: 启动 OpenPi 策略服务器** - -在 OpenPi 库中启动策略服务器： - -```bash -# 进入 OpenPi 目录 -cd /path/to/openpi - -# 启动策略服务器（使用迭代 20,000 的检查点，可根据需要修改） -uv run scripts/serve_policy.py policy:checkpoint \ - --policy.config=pi0_fast_libero \ - --policy.dir=checkpoints/pi0_fast_libero/my_experiment/20000 -``` - -服务器将在端口 8000 上监听（默认配置）。 - -**步骤 2: 配置 OpenPi 策略** - -```python -policy = OpenPI( - host="0.0.0.0", # 服务器主机地址 - port=8000, # 服务器端口 - replan_steps=4 # 重新规划步数 -) -``` - -**步骤 3: 运行评估** - -```bash -python scripts/evaluate_policy.py \ - --task_suite preposition_generalization \ - --task_level 0 \ - --n-episode 1 \ - --policy openpi \ - --save-dir logs/evaluation -``` - -**注意事项：** -- 确保 OpenPi 服务器在评估开始前已启动并运行 -- 如果使用不同的端口，请在策略配置中相应修改 `port` 参数 -- 服务器地址默认为 `0.0.0.0`，如需连接远程服务器，请修改 `host` 参数 -- 评估过程中请保持服务器运行，否则会导致连接失败 - -## 评估结果存储 - -### 目录结构 - -评估完成后，结果将保存在指定的目录中，目录结构如下： - -``` -logs/evaluation/ -└── eval_preposition_generalization_L0-2_OpenVLA_20241201_143022/ - ├── evaluation_metadata.json # 评估元数据 - ├── complete_metrics.json # 完整指标数据 -

This guide will walk you through how to fine-tune and evaluate various VLA models using datasets generated by VLA-Arena. We currently support fine-tuning and evaluation for OpenVLA, OpenVLA-OFT, Openpi, UniVLA, and SmolVLA models. + +## General Models (OpenVLA, OpenVLA-OFT, UniVLA, SmolVLA) + +For models other than Openpi (OpenVLA, OpenVLA-OFT, UniVLA, SmolVLA), the usage is very straightforward: + +### Install Dependencies + +First, install the dependencies for the corresponding model: + +```bash +conda create -n [model_name]_vla_arena python==3.10 -y +pip install -e . +pip install vla-arena[model_name] +``` + +Examples: +- OpenVLA: `pip install vla-arena[openvla]` +- OpenVLA-OFT: `pip install vla-arena[openvla-oft]` +- UniVLA: `pip install vla-arena[univla]` +- SmolVLA: `pip install vla-arena[smolvla]` + +### Fine-tune Model + +Use the following command to fine-tune: + +```bash +vla-arena train --model --config +``` + +Example: +```bash +vla-arena train --model openvla --config /vla_arena/config/openvla.yaml +``` + +### Evaluate Model + +Use the following command to evaluate: + +```bash +vla-arena eval --model --config +``` + +Example: +```bash +vla-arena eval --model openvla --config /path/to/config.yaml +``` + +--- + +## Openpi + +The Openpi model requires using `uv` for environment management, and the steps are slightly different from other models. + +### Environment Setup + +1. Create a new environment and navigate to the Openpi directory: + +```bash +conda create -n openpi python=3.11 -y +conda activate openpi +pip install uv +uv pip install -e . +cd vla_arena/models/openpi +``` + +2. Use uv to sync dependencies and install: + +```bash +uv sync +uv pip install -e . +``` + +### Define Training Configuration and Run Training + +Before running training, we need to compute normalization statistics for the training data. Run the following script with your training configuration name. Training configurations can be adjusted in `src/openpi/training/config`: + +```bash +uv run scripts/compute_norm_stats.py --config-name +``` + +**Note**: We provide functionality to reload state/action normalization statistics from pretraining. This can be beneficial if you are fine-tuning on a new task with a robot included in the pretraining mixed dataset. For more detailed information on how to reload normalization statistics, please refer to the `docs/norm_stats.md` file. + +Now we can start training (the `--overwrite` flag is used to overwrite existing checkpoints when you rerun fine-tuning with the same configuration): + +```bash +XLA_PYTHON_CLIENT_MEM_FRACTION=0.9 uv run trainer.py --config +``` + +This command will log training progress to the console and save checkpoints to the `checkpoints` directory. You can also monitor training progress on the Weights & Biases dashboard. To maximize GPU memory usage, set `XLA_PYTHON_CLIENT_MEM_FRACTION=0.9` before running training—this allows JAX to use up to 90% of GPU memory (the default is 75%). + +### Start Policy Server and Run Inference + +After training is complete, we can run inference by starting a policy server and then querying it from an evaluation script. Starting the model server is straightforward (this example uses the checkpoint from iteration 20,000, please modify as needed): + +```bash +uv run scripts/serve_policy.py policy:checkpoint --policy.config= --policy.dir=checkpoints/pi05_libero/my_experiment/20000 +``` + +This will start a server listening on port 8000, waiting for observation data to be sent to it. Then we can run an evaluation script (or robot runtime) to query the server. +If you want to embed policy server calls in your own robot runtime, we provide a minimal example in the remote inference documentation. + +### Evaluate Model + +After starting the policy server, run the following in the openpi directory: + +```bash +uv run evaluator.py --config +``` + +--- + +## Configuration File Notes + +Configuration files typically contain information such as dataset paths, model parameters, training hyperparameters, etc. Please refer to the corresponding configuration examples based on the model type you are using. diff --git a/docs/finetuning_and_evaluation_zh.md b/docs/finetuning_and_evaluation_zh.md new file mode 100644 index 00000000..e6df25a5 --- /dev/null +++ b/docs/finetuning_and_evaluation_zh.md @@ -0,0 +1,117 @@ +# 使用VLA-Arena生成的数据集微调其他模型并评测指南 + +VLA-Arena提供了完整的搜集数据、转换数据格式、评估语言-视觉-动作模型的框架，本指南将带您了解如何使用VLA-Arena生成的数据集微调一些VLA模型并评测。我们目前提供OpenVLA、OpenVLA-OFT、Openpi、UniVLA、SmolVLA模型的微调与评测。 + + +## 通用模型（OpenVLA、OpenVLA-OFT、UniVLA、SmolVLA） + +对于除Openpi外的其他模型（OpenVLA、OpenVLA-OFT、UniVLA、SmolVLA），使用方式非常简单： + +### 安装依赖 + +首先安装对应模型的依赖： + +```bash +conda create -n [model_name]_vla_arena python==3.10 -y +pip install -e . +pip install vla-arena[模型名称] +``` + +例如： +- OpenVLA: `pip install vla-arena[openvla]` +- OpenVLA-OFT: `pip install vla-arena[openvla-oft]` +- UniVLA: `pip install vla-arena[univla]` +- SmolVLA: `pip install vla-arena[smolvla]` + +### 微调模型 + +使用以下命令进行微调： + +```bash +vla-arena train --model <模型名称> --config <配置文件路径> +``` + +例如： +```bash +vla-arena train --model openvla --config /vla_arena/config/openvla.yaml +``` + +### 评估模型 + +使用以下命令进行评估： + +```bash +vla-arena eval --model <模型名称> --config <配置文件路径> +``` + +例如： +```bash +vla-arena eval --model openvla --config /path/to/config.yaml +``` + +--- + +## Openpi + +Openpi模型需要使用`uv`进行环境管理，操作步骤与其他模型略有不同。 + +### 环境配置 + +1. 创建新环境并进入Openpi目录： + +```bash +conda create -n openpi python=3.11 -y +conda activate openpi +pip install uv +uv pip install -e . +cd vla_arena/models/openpi +``` + +2. 使用uv同步依赖并安装： + +```bash +uv sync +uv pip install -e . +``` + +### 定义训练配置并运行训练 + +在运行训练之前，我们需要先计算训练数据的归一化统计信息。使用您的训练配置名称运行以下脚本，训练配置可在src/openpi/training/config中调整： + +```bash +uv run scripts/compute_norm_stats.py --config-name +``` + +**注意**：我们提供了从预训练中重新加载状态/动作归一化统计信息的功能。如果您在预训练混合数据集中包含的机器人上进行新任务的微调，这可能会有益。有关如何重新加载归一化统计信息的更多详细信息，请参阅 `docs/norm_stats.md` 文件。 +现在我们可以开始训练（`--overwrite` 标志用于在您使用相同配置重新运行微调时覆盖现有检查点）： + +```bash +XLA_PYTHON_CLIENT_MEM_FRACTION=0.9 uv run trainer.py --config <配置文件路径> +``` + +该命令会将训练进度记录到控制台，并将检查点保存到 `checkpoints` 目录。您也可以在 Weights & Biases 仪表板上监控训练进度。为了最大化使用GPU内存，在运行训练之前设置 `XLA_PYTHON_CLIENT_MEM_FRACTION=0.9`——这使JAX能够使用高达90%的GPU内存（默认值为75%）。 + +### 启动策略服务器并运行推理 + +训练完成后，我们可以通过启动策略服务器，然后从评估脚本查询它来运行推理。启动模型服务器很简单（此示例使用迭代20,000的检查点，请根据需要修改）： + +```bash +uv run scripts/serve_policy.py policy:checkpoint --policy.config= --policy.dir=checkpoints/pi05_libero/my_experiment/20000 +``` + +这将启动一个监听端口8000的服务器，等待发送给它的观测数据。然后我们可以运行一个评估脚本（或机器人运行时）来查询服务器。 +如果您想在自己的机器人运行时中嵌入策略服务器调用，我们在远程推理文档中提供了一个最小示例。 + +### 评估模型 + +在启动策略服务器后，openpi目录下运行： + +```bash +uv run evaluator.py --config <配置文件路径> +``` + +--- + +## 配置文件说明 + +配置文件通常包含数据集路径、模型参数、训练超参数等信息。请根据您使用的模型类型，参考相应的配置示例进行设置。 diff --git a/docs/scene_construction.md b/docs/scene_construction.md index 9fc1f2f5..73d63308 100644 --- a/docs/scene_construction.md +++ b/docs/scene_construction.md @@ -56,10 +56,10 @@ Regions define the spatial scope where objects can be placed. - `ranges` : The XY-plane range in the target coordinate system, formatted as `(x_min y_min x_max y_max)` - `yaw_rotation`(Optional) : Rotation angle of the region (only valid for `fixtures`) -### 1.3 Object Definition +### 1.3 Object Definition -#### Fixtures -Objects that do not move in the environment: +#### Fixtures +Objects that do not move in the environment: ```lisp (:fixtures @@ -86,7 +86,7 @@ Objects directly related to the task: ``` #### Moving Objects -Define objects that move autonomously in the scene, supporting multiple motion modes: +Define objects that move autonomously in the scene, supporting multiple motion modes: ```lisp (:moving_objects @@ -130,7 +130,7 @@ Define objects that move autonomously in the scene, supporting multiple motion m (:motion_direction (0 1 0)) ; Initial direction (:motion_gravity (0 0 -9.81)) ; Gravity vector ``` -### 1.4 State Definition +### 1.4 State Definition #### Initial State Defines the initial configuration of the scene: @@ -256,6 +256,12 @@ Here is an example: Then view the generated video in the `rollouts` directory:

In other words, the same value used with one codec doesn't necessarily translate into the same compression level with another codec. In fact, the default value (`None`) isn't the same amongst the different video codecs. Importantly, it is also the case for many other ffmpeg arguments like `g` which specifies the frequency of the key frames. + +For a comprehensive list and documentation of these parameters, see the ffmpeg documentation depending on the video codec used: + +- h264: https://trac.ffmpeg.org/wiki/Encode/H.264 +- h265: https://trac.ffmpeg.org/wiki/Encode/H.265 +- AV1: https://trac.ffmpeg.org/wiki/Encode/AV1 + +### Decoding parameters + +**Decoder** +We tested two video decoding backends from torchvision: + +- `pyav` +- `video_reader` (requires to build torchvision from source) + +**Requested timestamps** +Given the way video decoding works, once a keyframe has been loaded, the decoding of subsequent frames is fast. +This of course is affected by the `-g` parameter during encoding, which specifies the frequency of the keyframes. Given our typical use cases in robotics policies which might request a few timestamps in different random places, we want to replicate these use cases with the following scenarios: + +- `1_frame`: 1 frame, +- `2_frames`: 2 consecutive frames (e.g. `[t, t + 1 / fps]`), +- `6_frames`: 6 consecutive frames (e.g. `[t + i / fps for i in range(6)]`) + +Note that this differs significantly from a typical use case like watching a movie, in which every frame is loaded sequentially from the beginning to the end and it's acceptable to have big values for `-g`. + +Additionally, because some policies might request single timestamps that are a few frames apart, we also have the following scenario: + +- `2_frames_4_space`: 2 frames with 4 consecutive frames of spacing in between (e.g `[t, t + 5 / fps]`), + +However, due to how video decoding is implemented with `pyav`, we don't have access to an accurate seek so in practice this scenario is essentially the same as `6_frames` since all 6 frames between `t` and `t + 5 / fps` will be decoded. + +## Metrics + +**Data compression ratio (lower is better)** +`video_images_size_ratio` is the ratio of the memory space on disk taken by the encoded video over the memory space taken by the original images. For instance, `video_images_size_ratio=25%` means that the video takes 4 times less memory space on disk compared to the original images. + +**Loading time ratio (lower is better)** +`video_images_load_time_ratio` is the ratio of the time it takes to decode frames from the video at a given timestamps over the time it takes to load the exact same original images. Lower is better. For instance, `video_images_load_time_ratio=200%` means that decoding from video is 2 times slower than loading the original images. + +**Average Mean Square Error (lower is better)** +`avg_mse` is the average mean square error between each decoded frame and its corresponding original image over all requested timestamps, and also divided by the number of pixels in the image to be comparable when switching to different image sizes. + +**Average Peak Signal to Noise Ratio (higher is better)** +`avg_psnr` measures the ratio between the maximum possible power of a signal and the power of corrupting noise that affects the fidelity of its representation. Higher PSNR indicates better quality. + +**Average Structural Similarity Index Measure (higher is better)** +`avg_ssim` evaluates the perceived quality of images by comparing luminance, contrast, and structure. SSIM values range from -1 to 1, where 1 indicates perfect similarity. + +One aspect that can't be measured here with those metrics is the compatibility of the encoding across platforms, in particular on web browser, for visualization purposes. +h264, h265 and AV1 are all commonly used codecs and should not pose an issue. However, the chroma subsampling (`pix_fmt`) format might affect compatibility: + +- `yuv420p` is more widely supported across various platforms, including web browsers. +- `yuv444p` offers higher color fidelity but might not be supported as broadly. + + + +## How the benchmark works + +The benchmark evaluates both encoding and decoding of video frames on the first episode of each dataset. + +**Encoding:** for each `vcodec` and `pix_fmt` pair, we use a default value for `g` and `crf` upon which we change a single value (either `g` or `crf`) to one of the specified values (we don't test every combination of those as this would be computationally too heavy). +This gives a unique set of encoding parameters which is used to encode the episode. + +**Decoding:** Then, for each of those unique encodings, we iterate through every combination of the decoding parameters `backend` and `timestamps_mode`. For each of them, we record the metrics of a number of samples (given by `--num-samples`). This is parallelized for efficiency and the number of processes can be controlled with `--num-workers`. Ideally, it's best to have a `--num-samples` that is divisible by `--num-workers`. + +Intermediate results saved for each `vcodec` and `pix_fmt` combination in csv tables. +These are then all concatenated to a single table ready for analysis. + +## Caveats + +We tried to measure the most impactful parameters for both encoding and decoding. However, for computational reasons we can't test out every combination. + +Additional encoding parameters exist that are not included in this benchmark. In particular: + +- `-preset` which allows for selecting encoding presets. This represents a collection of options that will provide a certain encoding speed to compression ratio. By leaving this parameter unspecified, it is considered to be `medium` for libx264 and libx265 and `8` for libsvtav1. +- `-tune` which allows to optimize the encoding for certain aspects (e.g. film quality, fast decoding, etc.). + +See the documentation mentioned above for more detailed info on these settings and for a more comprehensive list of other parameters. + +Similarly on the decoding side, other decoders exist but are not implemented in our current benchmark. To name a few: + +- `torchaudio` +- `ffmpegio` +- `decord` +- `nvc` + +Note as well that since we are mostly interested in the performance at decoding time (also because encoding is done only once before uploading a dataset), we did not measure encoding times nor have any metrics regarding encoding. +However, besides the necessity to build ffmpeg from source, encoding did not pose any issue and it didn't take a significant amount of time during this benchmark. + +## Install + +Building ffmpeg from source is required to include libx265 and libaom/libsvtav1 (av1) video codecs ([compilation guide](https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu)). + +**Note:** While you still need to build torchvision with a conda-installed `ffmpeg<4.3` to use the `video_reader` decoder (as described in [#220](https://github.com/huggingface/lerobot/pull/220)), you also need another version which is custom-built with all the video codecs for encoding. For the script to then use that version, you can prepend the command above with `PATH="$HOME/bin:$PATH"`, which is where ffmpeg should be built. + +## Adding a video decoder + +Right now, we're only benchmarking the two video decoder available with torchvision: `pyav` and `video_reader`. +You can easily add a new decoder to benchmark by adding it to this function in the script: + +```diff +def decode_video_frames( + video_path: str, + timestamps: list[float], + tolerance_s: float, + backend: str, +) -> torch.Tensor: + if backend in ["pyav", "video_reader"]: + return decode_video_frames_torchvision( + video_path, timestamps, tolerance_s, backend + ) ++ elif backend == ["your_decoder"]: ++ return your_decoder_function( ++ video_path, timestamps, tolerance_s, backend ++ ) + else: + raise NotImplementedError(backend) +``` + +## Example + +For a quick run, you can try these parameters: + +```bash +python benchmark/video/run_video_benchmark.py \ +

Under the hood, this is done with [Draccus](https://github.com/dlwh/draccus) which is a tool dedicated to this purpose. If you're familiar with Hydra, Draccus can similarly load configurations from config files (.json, .yaml) and also override their values through command line inputs. Unlike Hydra, these configurations are pre-defined in the code through dataclasses rather than being defined entirely in config files. This allows for more rigorous serialization/deserialization, typing, and to manipulate configuration as objects directly in the code and not as dictionaries or namespaces (which enables nice features in an IDE such as autocomplete, jump-to-def, etc.) + +Let's have a look at a simplified example. Amongst other attributes, the training config has the following attributes: + + +```python +@dataclass +class TrainPipelineConfig: + dataset: DatasetConfig + env: envs.EnvConfig | None = None + policy: PreTrainedConfig | None = None +``` + + +in which `DatasetConfig` for example is defined as such: + + +```python +@dataclass +class DatasetConfig: + repo_id: str + episodes: list[int] | None = None + video_backend: str = "pyav" +``` + + +This creates a hierarchical relationship where, for example assuming we have a `cfg` instance of `TrainPipelineConfig`, we can access the `repo_id` value with `cfg.dataset.repo_id`. +From the command line, we can specify this value by using a very similar syntax `--dataset.repo_id=repo/id`. + +By default, every field takes its default value specified in the dataclass. If a field doesn't have a default value, it needs to be specified either from the command line or from a config file – which path is also given in the command line (more in this below). In the example above, the `dataset` field doesn't have a default value which means it must be specified. + +## Specifying values from the CLI + +Let's say that we want to train [Diffusion Policy](../src/lerobot/policies/diffusion) on the [pusht](https://huggingface.co/datasets/lerobot/pusht) dataset, using the [gym_pusht](https://github.com/huggingface/gym-pusht) environment for evaluation. The command to do so would look like this: + +```bash +lerobot-train \ + --dataset.repo_id=lerobot/pusht \ + --policy.type=diffusion \ + --env.type=pusht +``` + +Let's break this down: + +- To specify the dataset, we just need to specify its `repo_id` on the hub which is the only required argument in the `DatasetConfig`. The rest of the fields have default values and in this case we are fine with those so we can just add the option `--dataset.repo_id=lerobot/pusht`. +- To specify the policy, we can just select diffusion policy using `--policy` appended with `.type`. Here, `.type` is a special argument which allows us to select config classes inheriting from `draccus.ChoiceRegistry` and that have been decorated with the `register_subclass()` method. To have a better explanation of this feature, have a look at this [Draccus demo](https://github.com/dlwh/draccus?tab=readme-ov-file#more-flexible-configuration-with-choice-types). In our code, we use this mechanism mainly to select policies, environments, robots, and some other components like optimizers. The policies available to select are located in [lerobot/policies](../src/lerobot/policies) +- Similarly, we select the environment with `--env.type=pusht`. The different environment configs are available in [`lerobot/envs/configs.py`](../src/lerobot/envs/configs.py) + +Let's see another example. Let's say you've been training [ACT](../src/lerobot/policies/act) on [lerobot/aloha_sim_insertion_human](https://huggingface.co/datasets/lerobot/aloha_sim_insertion_human) using the [gym-aloha](https://github.com/huggingface/gym-aloha) environment for evaluation with: + +```bash +lerobot-train \ + --policy.type=act \ + --dataset.repo_id=lerobot/aloha_sim_insertion_human \ + --env.type=aloha \ + --output_dir=outputs/train/act_aloha_insertion +``` + +> Notice we added `--output_dir` to explicitly tell where to write outputs from this run (checkpoints, training state, configs etc.). This is not mandatory and if you don't specify it, a default directory will be created from the current date and time, env.type and policy.type. This will typically look like `outputs/train/2025-01-24/16-10-05_aloha_act`. + +We now want to train a different policy for aloha on another task. We'll change the dataset and use [lerobot/aloha_sim_transfer_cube_human](https://huggingface.co/datasets/lerobot/aloha_sim_transfer_cube_human) instead. Of course, we also need to change the task of the environment as well to match this other task. +Looking at the [`AlohaEnv`](../src/lerobot/envs/configs.py) config, the task is `"AlohaInsertion-v0"` by default, which corresponds to the task we trained on in the command above. The [gym-aloha](https://github.com/huggingface/gym-aloha?tab=readme-ov-file#description) environment also has the `AlohaTransferCube-v0` task which corresponds to this other task we want to train on. Putting this together, we can train this new policy on this different task using: + +```bash +lerobot-train \ + --policy.type=act \ + --dataset.repo_id=lerobot/aloha_sim_transfer_cube_human \ + --env.type=aloha \ + --env.task=AlohaTransferCube-v0 \ + --output_dir=outputs/train/act_aloha_transfer +``` + +## Loading from a config file + +Now, let's assume that we want to reproduce the run just above. That run has produced a `train_config.json` file in its checkpoints, which serializes the `TrainPipelineConfig` instance it used: + +```json +{ + "dataset": { + "repo_id": "lerobot/aloha_sim_transfer_cube_human", + "episodes": null, + ... + }, + "env": { + "type": "aloha", + "task": "AlohaTransferCube-v0", + "fps": 50, + ... + }, + "policy": { + "type": "act", + "n_obs_steps": 1, + ... + }, + ... +} +``` + +We can then simply load the config values from this file using: + +```bash +lerobot-train \ + --config_path=outputs/train/act_aloha_transfer/checkpoints/last/pretrained_model/ \ + --output_dir=outputs/train/act_aloha_transfer_2 +``` + +`--config_path` is also a special argument which allows to initialize the config from a local config file. It can point to a directory that contains `train_config.json` or to the config file itself directly. + +Similarly to Hydra, we can still override some parameters in the CLI if we want to, e.g.: + +```bash +lerobot-train \ + --config_path=outputs/train/act_aloha_transfer/checkpoints/last/pretrained_model/ \ + --output_dir=outputs/train/act_aloha_transfer_2 + --policy.n_action_steps=80 +``` + +> Note: While `--output_dir` is not required in general, in this case we need to specify it since it will otherwise take the value from the `train_config.json` (which is `outputs/train/act_aloha_transfer`). In order to prevent accidental deletion of previous run checkpoints, we raise an error if you're trying to write in an existing directory. This is not the case when resuming a run, which is what you'll learn next. + +`--config_path` can also accept the repo_id of a repo on the hub that contains a `train_config.json` file, e.g. running: + +```bash +lerobot-train --config_path=lerobot/diffusion_pusht +``` + +will start a training run with the same configuration used for training [lerobot/diffusion_pusht](https://huggingface.co/lerobot/diffusion_pusht) + +## Resume training + +Being able to resume a training run is important in case it crashed or aborted for any reason. We'll demonstrate how to do that here. + +Let's reuse the command from the previous run and add a few more options: + +```bash +lerobot-train \ + --policy.type=act \ + --dataset.repo_id=lerobot/aloha_sim_transfer_cube_human \ + --env.type=aloha \ + --env.task=AlohaTransferCube-v0 \ + --log_freq=25 \ + --save_freq=100 \ + --output_dir=outputs/train/run_resumption +``` + +Here we've taken care to set up the log frequency and checkpointing frequency to low numbers so we can showcase resumption. You should be able to see some logging and have a first checkpoint within 1 minute (depending on hardware). Wait for the first checkpoint to happen, you should see a line that looks like this in your terminal: + +``` +INFO 2025-01-24 16:10:56 ts/train.py:263 Checkpoint policy after step 100 +``` + +Now let's simulate a crash by killing the process (hit `ctrl`+`c`). We can then simply resume this run from the last checkpoint available with: + +```bash +lerobot-train \ + --config_path=outputs/train/run_resumption/checkpoints/last/pretrained_model/ \ + --resume=true +``` + +You should see from the logging that your training picks up from where it left off. + +Another reason for which you might want to resume a run is simply to extend training and add more training steps. The number of training steps is set by the option `--steps`, which is 100 000 by default. +You could double the number of steps of the previous run with: + +```bash +lerobot-train \ + --config_path=outputs/train/run_resumption/checkpoints/last/pretrained_model/ \ + --resume=true \ + --steps=200000 +``` + +## Outputs of a run + +In the output directory, there will be a folder called `checkpoints` with the following structure: + +```bash +outputs/train/run_resumption/checkpoints +├── 000100 # checkpoint_dir for training step 100 +│ ├── pretrained_model/ +│ │ ├── config.json # policy config +│ │ ├── model.safetensors # policy weights +│ │ └── train_config.json # train config +│ └── training_state/ +│ ├── optimizer_param_groups.json # optimizer param groups +│ ├── optimizer_state.safetensors # optimizer state +│ ├── rng_state.safetensors # rng states +│ ├── scheduler_state.json # scheduler state +│ └── training_step.json # training step +├── 000200 +└── last -> 000200 # symlink to the last available checkpoint +``` + +## Fine-tuning a pre-trained policy + +In addition to the features currently in Draccus, we've added a special `.path` argument for the policy, which allows to load a policy as you would with `PreTrainedPolicy.from_pretrained()`. In that case, `path` can be a local directory that contains a checkpoint or a repo_id pointing to a pretrained policy on the hub. + +For example, we could fine-tune a [policy pre-trained on the aloha transfer task](https://huggingface.co/lerobot/act_aloha_sim_transfer_cube_human) on the aloha insertion task. We can achieve this with: + +```bash +lerobot-train \ + --policy.path=lerobot/act_aloha_sim_transfer_cube_human \ + --dataset.repo_id=lerobot/aloha_sim_insertion_human \ + --env.type=aloha \ + --env.task=AlohaInsertion-v0 +``` + +When doing so, keep in mind that the features of the fine-tuning dataset would have to match the input/output features of the pretrained policy. + +## Typical logs and metrics + +When you start the training process, you will first see your full configuration being printed in the terminal. You can check it to make sure that you configured your run correctly. The final configuration will also be saved with the checkpoint. + +After that, you will see training log like this one: + +``` +INFO 2024-08-14 13:35:12 ts/train.py:192 step:0 smpl:64 ep:1 epch:0.00 loss:1.112 grdn:15.387 lr:2.0e-07 updt_s:1.738 data_s:4.774 +``` + +or evaluation log: + +``` +INFO 2024-08-14 13:38:45 ts/train.py:226 step:100 smpl:6K ep:52 epch:0.25 ∑rwrd:20.693 success:0.0% eval_s:120.266 +``` + +These logs will also be saved in wandb if `wandb.enable` is set to `true`. Here are the meaning of some abbreviations: + +- `smpl`: number of samples seen during training. +- `ep`: number of episodes seen during training. An episode contains multiple samples in a complete manipulation task. +- `epch`: number of time all unique samples are seen (epoch). +- `grdn`: gradient norm. +- `∑rwrd`: compute the sum of rewards in every evaluation episode and then take an average of them. +- `success`: average success rate of eval episodes. Reward and success are usually different except for the sparsing reward setting, where reward=1 only when the task is completed successfully. +- `eval_s`: time to evaluate the policy in the environment, in second. +- `updt_s`: time to update the network parameters, in second. +- `data_s`: time to load a batch of data, in second. + +Some metrics are useful for initial performance profiling. For example, if you find the current GPU utilization is low via the `nvidia-smi` command and `data_s` sometimes is too high, you may need to modify batch size or number of dataloading workers to accelerate dataloading. We also recommend [pytorch profiler](https://github.com/huggingface/lerobot?tab=readme-ov-file#improve-your-code-with-profiling) for detailed performance probing. + +## In short + +We'll summarize here the main use cases to remember from this tutorial. + +#### Train a policy from scratch – CLI + +```bash +lerobot-train \ + --policy.type=act \ # <- select 'act' policy + --env.type=pusht \ # <- select 'pusht' environment + --dataset.repo_id=lerobot/pusht # <- train on this dataset +``` + +#### Train a policy from scratch - config file + CLI + +```bash +lerobot-train \ + --config_path=path/to/pretrained_model \ # <- can also be a repo_id + --policy.n_action_steps=80 # <- you may still override values +``` + +#### Resume/continue a training run + +```bash +lerobot-train \ + --config_path=checkpoint/pretrained_model/ \ + --resume=true \ + --steps=200000 # <- you can change some training parameters +``` + +#### Fine-tuning + +```bash +lerobot-train \ + --policy.path=lerobot/act_aloha_sim_transfer_cube_human \ # <- can also be a local path to a checkpoint + --dataset.repo_id=lerobot/aloha_sim_insertion_human \ + --env.type=aloha \ + --env.task=AlohaInsertion-v0 +``` + +--- + +Now that you know the basics of how to train a policy, you might want to know how to apply this knowledge to actual robots, or how to record your own datasets and train policies on your specific task? +If that's the case, head over to the next tutorial [`7_get_started_with_real_robot.md`](./7_get_started_with_real_robot.md). + +Or in the meantime, happy training! 🤗 diff --git a/vla_arena/models/smolvla/examples/backward_compatibility/replay.py b/vla_arena/models/smolvla/examples/backward_compatibility/replay.py new file mode 100644 index 00000000..caef170d --- /dev/null +++ b/vla_arena/models/smolvla/examples/backward_compatibility/replay.py @@ -0,0 +1,119 @@ +# Copyright 2025 The VLA-Arena Authors. +# +# Licensed under the Apache License, Version 2.0 (the "License"); +# you may not use this file except in compliance with the License. +# You may obtain a copy of the License at +# +# http://www.apache.org/licenses/LICENSE-2.0 +# +# Unless required by applicable law or agreed to in writing, software +# distributed under the License is distributed on an "AS IS" BASIS, +# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +# See the License for the specific language governing permissions and +# limitations under the License. + +# Copyright 2024 The HuggingFace Inc. team.

+ +## Installation + +LeRobot works with Python 3.10+ and PyTorch 2.2+. + +### Environment Setup + +Create a virtual environment with Python 3.10 and activate it, e.g. with [`miniconda`](https://docs.anaconda.com/free/miniconda/index.html): + +```bash +conda create -y -n lerobot python=3.10 +conda activate lerobot +``` + +When using `miniconda`, install `ffmpeg` in your environment: + +```bash +conda install ffmpeg -c conda-forge +``` + +> **NOTE:** This usually installs `ffmpeg 7.X` for your platform compiled with the `libsvtav1` encoder. If `libsvtav1` is not supported (check supported encoders with `ffmpeg -encoders`), you can: +> +> - _[On any platform]_ Explicitly install `ffmpeg 7.X` using: +> +> ```bash +> conda install ffmpeg=7.1.1 -c conda-forge +> ``` +> +> - _[On Linux only]_ Install [ffmpeg build dependencies](https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu#GettheDependencies) and [compile ffmpeg from source with libsvtav1](https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu#libsvtav1), and make sure you use the corresponding ffmpeg binary to your install with `which ffmpeg`. + +### Install LeRobot 🤗 + +#### From Source + +First, clone the repository and navigate into the directory: + +```bash +git clone https://github.com/huggingface/lerobot.git +cd lerobot +``` + +Then, install the library in editable mode. This is useful if you plan to contribute to the code. + +```bash +pip install -e . +``` + +> **NOTE:** If you encounter build errors, you may need to install additional dependencies (`cmake`, `build-essential`, and `ffmpeg libs`). On Linux, run: +> `sudo apt-get install cmake build-essential python3-dev pkg-config libavformat-dev libavcodec-dev libavdevice-dev libavutil-dev libswscale-dev libswresample-dev libavfilter-dev`. For other systems, see: [Compiling PyAV](https://pyav.org/docs/develop/overview/installation.html#bring-your-own-ffmpeg) + +For simulations, 🤗 LeRobot comes with gymnasium environments that can be installed as extras: + +- [aloha](https://github.com/huggingface/gym-aloha) +- [xarm](https://github.com/huggingface/gym-xarm) +- [pusht](https://github.com/huggingface/gym-pusht) + +For instance, to install 🤗 LeRobot with aloha and pusht, use: + +```bash +pip install -e ".[aloha, pusht]" +``` + +### Installation from PyPI + +**Core Library:** +Install the base package with: + +```bash +pip install lerobot +``` + +_This installs only the default dependencies._ + +**Extra Features:** +To install additional functionality, use one of the following: + +```bash +pip install 'lerobot[all]' # All available features +pip install 'lerobot[aloha,pusht]' # Specific features (Aloha & Pusht) +pip install 'lerobot[feetech]' # Feetech motor support +``` + +_Replace `[...]` with your desired features._ + +**Available Tags:** +For a full list of optional dependencies, see: +https://pypi.org/project/lerobot/ + +### Weights & Biases + +To use [Weights and Biases](https://docs.wandb.ai/quickstart) for experiment tracking, log in with + +```bash +wandb login +``` + +(note: you will also need to enable WandB in the configuration. See below.) + +### Visualize datasets + +Check out [example 1](https://github.com/huggingface/lerobot/blob/main/examples/1_load_lerobot_dataset.py) that illustrates how to use our dataset class which automatically downloads data from the Hugging Face hub. + +You can also locally visualize episodes from a dataset on the hub by executing our script from the command line: + +```bash +python -m lerobot.scripts.visualize_dataset \ + --repo-id lerobot/pusht \ + --episode-index 0 +``` + +or from a dataset in a local folder with the `root` option and the `--local-files-only` (in the following case the dataset will be searched for in `./my_local_data_dir/lerobot/pusht`) + +```bash +python -m lerobot.scripts.visualize_dataset \ + --repo-id lerobot/pusht \ + --root ./my_local_data_dir \ + --local-files-only 1 \ + --episode-index 0 +``` + +It will open `rerun.io` and display the camera streams, robot states and actions, like this: + +https://github-production-user-asset-6210df.s3.amazonaws.com/4681518/328035972-fd46b787-b532-47e2-bb6f-fd536a55a7ed.mov?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAVCODYLSA53PQK4ZA%2F20240505%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20240505T172924Z&X-Amz-Expires=300&X-Amz-Signature=d680b26c532eeaf80740f08af3320d22ad0b8a4e4da1bcc4f33142c15b509eda&X-Amz-SignedHeaders=host&actor_id=24889239&key_id=0&repo_id=748713144 + +Our script can also visualize datasets stored on a distant server. See `python -m lerobot.scripts.visualize_dataset --help` for more instructions. + +### The `LeRobotDataset` format + +A dataset in `LeRobotDataset` format is very simple to use. It can be loaded from a repository on the Hugging Face hub or a local folder simply with e.g. `dataset = LeRobotDataset("lerobot/aloha_static_coffee")` and can be indexed into like any Hugging Face and PyTorch dataset. For instance `dataset[0]` will retrieve a single temporal frame from the dataset containing observation(s) and an action as PyTorch tensors ready to be fed to a model. + +A specificity of `LeRobotDataset` is that, rather than retrieving a single frame by its index, we can retrieve several frames based on their temporal relationship with the indexed frame, by setting `delta_timestamps` to a list of relative times with respect to the indexed frame. For example, with `delta_timestamps = {"observation.image": [-1, -0.5, -0.2, 0]}` one can retrieve, for a given index, 4 frames: 3 "previous" frames 1 second, 0.5 seconds, and 0.2 seconds before the indexed frame, and the indexed frame itself (corresponding to the 0 entry). See example [1_load_lerobot_dataset.py](https://github.com/huggingface/lerobot/blob/main/examples/1_load_lerobot_dataset.py) for more details on `delta_timestamps`. + +Under the hood, the `LeRobotDataset` format makes use of several ways to serialize data which can be useful to understand if you plan to work more closely with this format. We tried to make a flexible yet simple dataset format that would cover most type of features and specificities present in reinforcement learning and robotics, in simulation and in real-world, with a focus on cameras and robot states but easily extended to other types of sensory inputs as long as they can be represented by a tensor. + +Here are the important details and internal structure organization of a typical `LeRobotDataset` instantiated with `dataset = LeRobotDataset("lerobot/aloha_static_coffee")`. The exact features will change from dataset to dataset but not the main aspects: + +``` +dataset attributes: + ├ hf_dataset: a Hugging Face dataset (backed by Arrow/parquet). Typical features example: + │ ├ observation.images.cam_high (VideoFrame): + │ │ VideoFrame = {'path': path to a mp4 video, 'timestamp' (float32): timestamp in the video} + │ ├ observation.state (list of float32): position of an arm joints (for instance) + │ ... (more observations) + │ ├ action (list of float32): goal position of an arm joints (for instance) + │ ├ episode_index (int64): index of the episode for this sample + │ ├ frame_index (int64): index of the frame for this sample in the episode ; starts at 0 for each episode + │ ├ timestamp (float32): timestamp in the episode + │ ├ next.done (bool): indicates the end of an episode ; True for the last frame in each episode + │ └ index (int64): general index in the whole dataset + ├ episode_data_index: contains 2 tensors with the start and end indices of each episode + │ ├ from (1D int64 tensor): first frame index for each episode — shape (num episodes,) starts with 0 + │ └ to: (1D int64 tensor): last frame index for each episode — shape (num episodes,) + ├ stats: a dictionary of statistics (max, mean, min, std) for each feature in the dataset, for instance + │ ├ observation.images.cam_high: {'max': tensor with same number of dimensions (e.g. `(c, 1, 1)` for images, `(c,)` for states), etc.} + │ ... + ├ info: a dictionary of metadata on the dataset + │ ├ codebase_version (str): this is to keep track of the codebase version the dataset was created with + │ ├ fps (float): frame per second the dataset is recorded/synchronized to + │ ├ video (bool): indicates if frames are encoded in mp4 video files to save space or stored as png files + │ └ encoding (dict): if video, this documents the main options that were used with ffmpeg to encode the videos + ├ videos_dir (Path): where the mp4 videos or png images are stored/accessed + └ camera_keys (list of string): the keys to access camera features in the item returned by the dataset (e.g. `["observation.images.cam_high", ...]`) +``` + +A `LeRobotDataset` is serialised using several widespread file formats for each of its parts, namely: + +- hf_dataset stored using Hugging Face datasets library serialization to parquet +- videos are stored in mp4 format to save space +- metadata are stored in plain json/jsonl files + +Dataset can be uploaded/downloaded from the HuggingFace hub seamlessly. To work on a local dataset, you can specify its location with the `root` argument if it's not in the default `~/.cache/huggingface/lerobot` location. + +### Evaluate a pretrained policy + +Check out [example 2](https://github.com/huggingface/lerobot/blob/main/examples/2_evaluate_pretrained_policy.py) that illustrates how to download a pretrained policy from Hugging Face hub, and run an evaluation on its corresponding environment. + +We also provide a more capable script to parallelize the evaluation over multiple environments during the same rollout. Here is an example with a pretrained model hosted on [lerobot/diffusion_pusht](https://huggingface.co/lerobot/diffusion_pusht): + +```bash +lerobot-eval \ + --policy.path=lerobot/diffusion_pusht \ + --env.type=pusht \ + --eval.batch_size=10 \ + --eval.n_episodes=10 \ + --policy.use_amp=false \ + --policy.device=cuda +``` + +Note: After training your own policy, you can re-evaluate the checkpoints with: + +```bash +lerobot-eval --policy.path={OUTPUT_DIR}/checkpoints/last/pretrained_model +``` + +See `lerobot-eval --help` for more instructions. + +### Train your own policy + +Check out [example 3](https://github.com/huggingface/lerobot/blob/main/examples/3_train_policy.py) that illustrates how to train a model using our core library in python, and [example 4](https://github.com/huggingface/lerobot/blob/main/examples/4_train_policy_with_script.md) that shows how to use our training script from command line. + +To use wandb for logging training and evaluation curves, make sure you've run `wandb login` as a one-time setup step. Then, when running the training command above, enable WandB in the configuration by adding `--wandb.enable=true`. + +A link to the wandb logs for the run will also show up in yellow in your terminal. Here is an example of what they look like in your browser. Please also check [here](https://github.com/huggingface/lerobot/blob/main/examples/4_train_policy_with_script.md#typical-logs-and-metrics) for the explanation of some commonly used metrics in logs. + +\WandB logs example + +Note: For efficiency, during training every checkpoint is evaluated on a low number of episodes. You may use `--eval.n_episodes=500` to evaluate on more episodes than the default. Or, after training, you may want to re-evaluate your best checkpoints on more episodes or change the evaluation settings. See `lerobot-eval --help` for more instructions. + +#### Reproduce state-of-the-art (SOTA) + +We provide some pretrained policies on our [hub page](https://huggingface.co/lerobot) that can achieve state-of-the-art performances. +You can reproduce their training by loading the config from their run. Simply running: + +```bash +lerobot-train --config_path=lerobot/diffusion_pusht +``` + +reproduces SOTA results for Diffusion Policy on the PushT task. + +## Contribute + +If you would like to contribute to 🤗 LeRobot, please check out our [contribution guide](https://github.com/huggingface/lerobot/blob/main/CONTRIBUTING.md). + +### Add a pretrained policy + +Once you have trained a policy you may upload it to the Hugging Face hub using a hub id that looks like `${hf_user}/${repo_name}` (e.g. [lerobot/diffusion_pusht](https://huggingface.co/lerobot/diffusion_pusht)). + +You first need to find the checkpoint folder located inside your experiment directory (e.g. `outputs/train/2024-05-05/20-21-12_aloha_act_default/checkpoints/002500`). Within that there is a `pretrained_model` directory which should contain: + +- `config.json`: A serialized version of the policy configuration (following the policy's dataclass config). +- `model.safetensors`: A set of `torch.nn.Module` parameters, saved in [Hugging Face Safetensors](https://huggingface.co/docs/safetensors/index) format. +- `train_config.json`: A consolidated configuration containing all parameters used for training. The policy configuration should match `config.json` exactly. This is useful for anyone who wants to evaluate your policy or for reproducibility. + +To upload these to the hub, run the following: + +```bash +huggingface-cli upload ${hf_user}/${repo_name} path/to/pretrained_model +``` + +See [eval.py](https://github.com/huggingface/lerobot/blob/main/src/lerobot/scripts/eval.py) for an example of how other people may use your policy. + +### Acknowledgment + +- The LeRobot team 🤗 for building SmolVLA [Paper](https://arxiv.org/abs/2506.01844), [Blog](https://huggingface.co/blog/smolvla). +- Thanks to Tony Zhao, Zipeng Fu and colleagues for open sourcing ACT policy, ALOHA environments and datasets.

You will be required to provide the 'tasks', which is a short but accurate description in plain English +for each of the task performed in the dataset. This will allow to easily train models with task-conditioning. + +We support 3 different scenarios for these tasks (see instructions below): + 1. Single task dataset: all episodes of your dataset have the same single task. + 2. Single task episodes: the episodes of your dataset each contain a single task but they can differ from + one episode to the next. + 3. Multi task episodes: episodes of your dataset may each contain several different tasks. + + +Can you can also provide a robot config .yaml file (not mandatory) to this script via the option +'--robot-config' so that it writes information about the robot (robot type, motors names) this dataset was +recorded with. For now, only Aloha/Koch type robots are supported with this option. + + +# 1. Single task dataset +If your dataset contains a single task, you can simply provide it directly via the CLI with the +'--single-task' option. + +Examples: + +```bash +python -m lerobot.datasets.v2.convert_dataset_v1_to_v2 \ + --repo-id lerobot/aloha_sim_insertion_human_image \ + --single-task "Insert the peg into the socket." \ + --robot-config lerobot/configs/robot/aloha.yaml \ + --local-dir data +``` + +```bash +python -m lerobot.datasets.v2.convert_dataset_v1_to_v2 \ + --repo-id aliberts/koch_tutorial \ + --single-task "Pick the Lego block and drop it in the box on the right." \ + --robot-config lerobot/configs/robot/koch.yaml \ + --local-dir data +``` + + +# 2. Single task episodes +If your dataset is a multi-task dataset, you have two options to provide the tasks to this script: + +- If your dataset already contains a language instruction column in its parquet file, you can simply provide + this column's name with the '--tasks-col' arg. + + Example: + + ```bash + python -m lerobot.datasets.v2.convert_dataset_v1_to_v2 \ + --repo-id lerobot/stanford_kuka_multimodal_dataset \ + --tasks-col "language_instruction" \ + --local-dir data + ``` + +- If your dataset doesn't contain a language instruction, you should provide the path to a .json file with the + '--tasks-path' arg. This file should have the following structure where keys correspond to each + episode_index in the dataset, and values are the language instruction for that episode. + + Example: + + ```json + { + "0": "Do something", + "1": "Do something else", + "2": "Do something", + "3": "Go there", + ... + } + ``` + +# 3. Multi task episodes +If you have multiple tasks per episodes, your dataset should contain a language instruction column in its +parquet file, and you must provide this column's name with the '--tasks-col' arg. + +Example: + +```bash +python -m lerobot.datasets.v2.convert_dataset_v1_to_v2 \ + --repo-id lerobot/stanford_kuka_multimodal_dataset \ + --tasks-col "language_instruction" \ + --local-dir data +``` +""" + +import argparse +import contextlib +import filecmp +import json +import logging +import math +import shutil +import subprocess +import tempfile +from pathlib import Path + +import datasets +import pyarrow.compute as pc +import pyarrow.parquet as pq +import torch +from datasets import Dataset +from huggingface_hub import HfApi +from huggingface_hub.errors import EntryNotFoundError, HfHubHTTPError +from lerobot.datasets.utils import ( + DEFAULT_CHUNK_SIZE, + DEFAULT_PARQUET_PATH, + DEFAULT_VIDEO_PATH, + EPISODES_PATH, + INFO_PATH, + STATS_PATH, + TASKS_PATH, + create_branch, + create_lerobot_dataset_card, + flatten_dict, + get_safe_version, + load_json, + unflatten_dict, + write_json, + write_jsonlines, +) +from lerobot.datasets.video_utils import VideoFrame #

(hint: Google + action repeats in Q-learning or ask your favorite chatbot) + horizon: Horizon for model predictive control. + n_action_steps: Number of action steps to take from the plan given by model predictive control. This + is an alternative to using action repeats. If this is set to more than 1, then we require + `n_action_repeats == 1`, `use_mpc == True` and `n_action_steps <= horizon`. Note that this + approach of using multiple steps from the plan is not in the original implementation. + input_shapes: A dictionary defining the shapes of the input data for the policy. The key represents + the input data name, and the value is a list indicating the dimensions of the corresponding data. + For example, "observation.image" refers to an input from a camera with dimensions [3, 96, 96], + indicating it has three color channels and 96x96 resolution. Importantly, `input_shapes` doesn't + include batch dimension or temporal dimension. + output_shapes: A dictionary defining the shapes of the output data for the policy. The key represents + the output data name, and the value is a list indicating the dimensions of the corresponding data. + For example, "action" refers to an output shape of [14], indicating 14-dimensional actions. + Importantly, `output_shapes` doesn't include batch dimension or temporal dimension. + input_normalization_modes: A dictionary with key representing the modality (e.g. "observation.state"), + and the value specifies the normalization mode to apply. The two available modes are "mean_std" + which subtracts the mean and divides by the standard deviation and "min_max" which rescale in a + [-1, 1] range. Note that here this defaults to None meaning inputs are not normalized. This is to + match the original implementation. + output_normalization_modes: Similar dictionary as `normalize_input_modes`, but to unnormalize to the + original scale. Note that this is also used for normalizing the training targets. NOTE: Clipping + to [-1, +1] is used during MPPI/CEM. Therefore, it is recommended that you stick with "min_max" + normalization mode here. + image_encoder_hidden_dim: Number of channels for the convolutional layers used for image encoding. + state_encoder_hidden_dim: Hidden dimension for MLP used for state vector encoding. + latent_dim: Observation's latent embedding dimension. + q_ensemble_size: Number of Q function estimators to use in an ensemble for uncertainty estimation. + mlp_dim: Hidden dimension of MLPs used for modelling the dynamics encoder, reward function, policy + (π), Q ensemble, and V. + discount: Discount factor (γ) to use for the reinforcement learning formalism. + use_mpc: Whether to use model predictive control. The alternative is to just sample the policy model + (π) for each step. + cem_iterations: Number of iterations for the MPPI/CEM loop in MPC. + max_std: Maximum standard deviation for actions sampled from the gaussian PDF in CEM. + min_std: Minimum standard deviation for noise applied to actions sampled from the policy model (π). + Doubles up as the minimum standard deviation for actions sampled from the gaussian PDF in CEM. + n_gaussian_samples: Number of samples to draw from the gaussian distribution every CEM iteration. Must + be non-zero. + n_pi_samples: Number of samples to draw from the policy / world model rollout every CEM iteration. Can + be zero. + uncertainty_regularizer_coeff: Coefficient for the uncertainty regularization used when estimating + trajectory values (this is the λ coefficient in eqn 4 of FOWM). + n_elites: The number of elite samples to use for updating the gaussian parameters every CEM iteration. + elite_weighting_temperature: The temperature to use for softmax weighting (by trajectory value) of the + elites, when updating the gaussian parameters for CEM. + gaussian_mean_momentum: Momentum (α) used for EMA updates of the mean parameter μ of the gaussian + parameters optimized in CEM. Updates are calculated as μ⁻ ← αμ⁻ + (1-α)μ. + max_random_shift_ratio: Maximum random shift (as a proportion of the image size) to apply to the + image(s) (in units of pixels) for training-time augmentation. If set to 0, no such augmentation + is applied. Note that the input images are assumed to be square for this augmentation. + reward_coeff: Loss weighting coefficient for the reward regression loss. + expectile_weight: Weighting (τ) used in expectile regression for the state value function (V). + v_pred < v_target is weighted by τ and v_pred >= v_target is weighted by (1-τ). τ is expected to + be in [0, 1]. Setting τ closer to 1 results in a more "optimistic" V. This is sensible to do + because v_target is obtained by evaluating the learned state-action value functions (Q) with + in-sample actions that may not be always optimal. + value_coeff: Loss weighting coefficient for both the state-action value (Q) TD loss, and the state + value (V) expectile regression loss. + consistency_coeff: Loss weighting coefficient for the consistency loss. + advantage_scaling: A factor by which the advantages are scaled prior to exponentiation for advantage + weighted regression of the policy (π) estimator parameters. Note that the exponentiated advantages + are clamped at 100.0. + pi_coeff: Loss weighting coefficient for the action regression loss. + temporal_decay_coeff: Exponential decay coefficient for decaying the loss coefficient for future time- + steps. Hint: each loss computation involves `horizon` steps worth of actions starting from the + current time step. + target_model_momentum: Momentum (α) used for EMA updates of the target models.

A few arguments are required. Here is an example command: + +```bash +lerobot-train \ + --dataset.repo_id=${HF_USER}/aloha_test \ + --policy.type=act \ + --output_dir=outputs/train/act_aloha_test \ + --job_name=act_aloha_test \ + --policy.device=cuda \ + --wandb.enable=true +``` + +Let's explain it: + +1. We provided the dataset as argument with `--dataset.repo_id=${HF_USER}/aloha_test`. +2. We provided the policy with `policy.type=act`. This loads configurations from [`configuration_act.py`](../src/lerobot/policies/act/configuration_act.py). Importantly, this policy will automatically adapt to the number of motor states, motor actions and cameras of your robot (e.g. `laptop` and `phone`) which have been saved in your dataset. +3. We provided `policy.device=cuda` since we are training on a Nvidia GPU, but you could use `policy.device=mps` to train on Apple silicon. +4. We provided `wandb.enable=true` to use [Weights and Biases](https://docs.wandb.ai/quickstart) for visualizing training plots. This is optional but if you use it, make sure you are logged in by running `wandb login`. + +For more information on the `train` script see the previous tutorial: [`examples/4_train_policy_with_script.md`](../examples/4_train_policy_with_script.md) + +Training should take several hours. You will find checkpoints in `outputs/train/act_aloha_test/checkpoints`. + +## Evaluate your policy + +You can use the `record` function from [`lerobot/scripts/control_robot.py`](../src/lerobot/scripts/control_robot.py) but with a policy checkpoint as input. For instance, run this command to record 10 evaluation episodes: + +```bash +python lerobot/scripts/control_robot.py \ + --robot.type=aloha \ + --control.type=record \ + --control.fps=30 \ + --control.single_task="Grasp a lego block and put it in the bin." \ + --control.repo_id=${HF_USER}/eval_act_aloha_test \ + --control.tags='["tutorial"]' \ + --control.warmup_time_s=5 \ + --control.episode_time_s=30 \ + --control.reset_time_s=30 \ + --control.num_episodes=10 \ + --control.push_to_hub=true \ + --control.policy.path=outputs/train/act_aloha_test/checkpoints/last/pretrained_model \ + --control.num_image_writer_processes=1 +``` + +As you can see, it's almost the same command as previously used to record your training dataset. Two things changed: + +1. There is an additional `--control.policy.path` argument which indicates the path to your policy checkpoint with (e.g. `outputs/train/eval_act_aloha_test/checkpoints/last/pretrained_model`). You can also use the model repository if you uploaded a model checkpoint to the hub (e.g. `${HF_USER}/act_aloha_test`). +2. The name of dataset begins by `eval` to reflect that you are running inference (e.g. `${HF_USER}/eval_act_aloha_test`). +3. We use `--control.num_image_writer_processes=1` instead of the default value (`0`). On our computer, using a dedicated process to write images from the 4 cameras on disk allows to reach constant 30 fps during inference. Feel free to explore different values for `--control.num_image_writer_processes`. + +## More + +Follow this [previous tutorial](https://github.com/huggingface/lerobot/blob/main/examples/7_get_started_with_real_robot.md#4-train-a-policy-on-your-data) for a more in-depth explanation. + +If you have any question or need help, please reach out on Discord in the channel `#aloha-arm`. diff --git a/vla_arena/models/smolvla/src/lerobot/robots/viperx/__init__.py b/vla_arena/models/smolvla/src/lerobot/robots/viperx/__init__.py new file mode 100644 index 00000000..ee9f05e9 --- /dev/null +++ b/vla_arena/models/smolvla/src/lerobot/robots/viperx/__init__.py @@ -0,0 +1,32 @@ +#!/usr/bin/env python + +# Copyright 2025 The VLA-Arena Authors. +# +# Licensed under the Apache License, Version 2.0 (the "License"); +# you may not use this file except in compliance with the License. +# You may obtain a copy of the License at +# +# http://www.apache.org/licenses/LICENSE-2.0 +# +# Unless required by applicable law or agreed to in writing, software +# distributed under the License is distributed on an "AS IS" BASIS, +# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +# See the License for the specific language governing permissions and +# limitations under the License. + +# Copyright 2025 The HuggingFace Inc. team.

Can be "normal" (mean 0, std 1) or "bounds" (normalized to [-1, 1]). + dataset_statistics: (dict|str, optional): dict (or path to JSON file) that contains dataset statistics + for normalization.
