[Feature Request] Add Detailed Information about Observation Fields to Metadata File in leRobotDataset Repository

[perezjln]

This feature would be useful for those who want to perform training using a collection of datasets.

Currently, you need to load each dataset and check the .keys() of a single item to access this information.

For example, the info file currently only contains:

{
    "codebase_version": "v1.5",
    "fps": 30,
    "video": true
}

Reference: Koch Pick Place 1 Lego Dataset Info

In this file, it would be helpful to also include the names and shapes of the available inputs.

Hi @perezjln,
We are indeed working on our dataset format to improve it and this is one of the features we want to add. We want it to be more transparent and not have to download the actual data to know its structure.
