You just recorded a LeRobot dataset with your robot. Maybe you also downloaded a dataset from the HuggingFace hub. With phospho, you can:
  • repair corrupted datasets
  • merge two datasets into one
  • split a dataset into multiple datasets (e.g. training/validation/test sets)
  • delete episodes from a dataset

​
Prerequisites

You need to install the phosphobot software on your computer. If you haven’t done it yet, follow the installation guide. 
curl -fsSL https://raw.githubusercontent.com/phospho-app/phosphobot/main/install.sh | bash
For any of this operations, go to the dashboard and click on the Browse Datasets tab. Then move to the lerobot_v2.1 folder. You will see all your local datasets. To download a dataset from the HuggingFace hub, click on the Add from hub button. It will be downloaded and added to your local datasets.

​
Repair a dataset

Select a dataset and click on the Repair Selected Dataset button. This will check that your dataset is valid and fix common LeRobot issues.

​
Merge two datasets

Select two datasets and click on the Merge Selected Datasets button. This will merge the two datasets into a single dataset. For now, you can only merge two local datasets at a time. If you need to merge more, you can do it recursively.

​
Split a dataset

Select a dataset and click on the Split Selected Dataset button. This will split the dataset into two datasets.

​
Delete a dataset

Select a dataset and click on the Delete Selected Dataset button. This will delete the dataset from your local datasets.

​
Upload the dataset back to HuggingFace

Click the 3 dots on the right of the dataset and select Push to Hugging Face Hub. This will upload the dataset to your HuggingFace account.

​
Visualize your dataset

Once your dataset is uploaded to HuggingFace, you can view it using the LeRobot Dataset Visualizer. This will also check that your dataset is valid. LeRobot dataset visualizer
The dataset visualizer only works with the AVC1 video codec. If you used another codec, you may see black screens in the video preview. Preview directly the videos files in a video player by opening your recording locally: ~/phosphobot/recordings/lerobot_v2/DATASET_NAME/video.
Looking good? You’re ready to train your AI model!
