When using LIBERO through LeRobot, policies interact with the environment via **observations** and **actions**:
|
||||
|
||||
- **Observations**
|
||||
- `observation.state` – proprioceptive features (agent state).
|
||||
- `observation.images.image` – main camera view (`agentview_image`).
|
||||
- `observation.images.image2` – wrist camera view (`robot0_eye_in_hand_image`).
|
||||
|
||||
⚠️ **Note:** LeRobot enforces the `.images.*` prefix for any visual features. Make sure your dataset metadata keys match this convention when evaluating.
