Rerun LeRobot ingestion

There are two ways in, and which one you want depends on whether you are viewing or converting.

• Just viewing? Rerun has a built-in LeRobot importer: point log_file_from_path (or the viewer, or rerun <dir> on the CLI) at the dataset directory and it ingests episodes, camera videos, and state/action tables with no conversion code.
• Converting? rr.experimental.LeRobotReader reads the dataset one episode at a time as a lazy chunk stream, which is what you want for per-episode RRDs and for lenses.

The download step needs huggingface_hub.

Step 0: pick a dataset and check the HF token

Both scripts below live in scripts/ next to this file, and run standalone through uv — they declare huggingface_hub inline, so there is no environment to set up.

Two facts decide what a dataset costs to fetch, and the Hub search results show neither. Get both, for every candidate, in one call:

uv run scripts/find_lerobot_dataset.py <query> --robot-type <robot> --want 5
