Bridge — LeRobot/GR00T format

BridgeData V2 converted to the GR00T-N1.7 training format: LeRobot v2.1 directory layout plus meta/modality.json. Validated by a 5-step GR00T-N1.7 fine-tuning smoke-train (loss decreased, checkpoint written) after conversion.

Contents

• Episodes: 20
• Frames: 460
• codebase_version: v2.1 (+ meta/modality.json for GR00T)

Note: this is a validation subset used to verify the v3→GR00T conversion pipeline end-to-end, not the full source dataset.

Source

Converted from BridgeData V2 (LeRobot v3.0) using the lerobot-groot-dataset-conversion pipeline, which wraps NVIDIA Isaac-GR00T's conversion scripts.

Usage

Load with GR00T-N1.7's LeRobotSingleDataset using embodiment_tag=new_embodiment and the matching modality config.
