You just recorded a dataset with your robot. Maybe you also downloaded a dataset from the HuggingFace hub.

With phospho, you can:

• repair it if it’s corrupted
• merge it with another dataset
• split it into multiple datasets (e.g. training/validation/test sets)
• delete it

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 wil see all your local datasets. To download a dataset from the HuggingFace hub, click on the Download dataset 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.

Looking good? You’re ready to train your AI model!
