DM05-Lerobot-LIBERO

DM05-Lerobot-LIBERO

DM05-Lerobot-LIBERO is a LIBERO-specific fine-tuned checkpoint based on Dexmal/DM05-Lerobot. It is not the general-purpose DM05 base model.

Model Configuration

• Cameras: front, wrist
• State dimension: 8
• Action dimension: 7
• chunk_size=10
• n_action_steps=10
• add_state=false
• Processor: use_relative_actions=false

For evaluation, use the LIBERO relative-controller protocol. The processor keeps the model action representation absolute; the controller protocol is an evaluation-time environment setting.

LIBERO Evaluation

The reported 50k-step result covers 40 tasks x 5 episodes per task = 200 episodes:

This is a 200-episode evaluation result, not a standard 2,000-episode complete LIBERO evaluation score.
