 ### 1. 数据结构标准
 数据集必须遵循 [Robomimic](https://robomimic.github.io/) 的层级结构：
 ```text
-dataset.hdf5
-├── data/
-│   ├── demo_0/
-│   │   ├── obs/
-│   │   │   ├── agentview_rgb   # (T, H, W, 3) uint8
-│   │   │   └── qpos            # (T, D) float32
-│   │   ├── actions             # (T, D) float32
-│   │   └── language            # (Attribute) String 指令
-│   └── ...
