Data Format

Each dataset contains multiple episodes stored in Parquet format:

LeRobot v3.0 (e.g., part_sorting_long_756_episode, Packing_Box, Foam_Inlaying, Conveyor_Sorting):

{dataset_name}/data/chunk-000/file-XXX.parquet

Data filename: file-{file_index}.parquet
Dataset ID format: {action}_{description} (e.g., part_sorting_long_756_episode)

Field definitions can be found in the main project at lerobot/common/policies/utils.py under observation/action definitions.
