from lerobot.common.datasets.lerobot_dataset import LeRobotDataset

dataset = LeRobotDataset("echwang/mydataset")
print(f"Episodes: {dataset.num_episodes}")
print(f"Frames: {dataset.num_frames}")
```

### With surro-cli

```bash
# Download
surro dataset download --name mydataset

# Upload a new episode
surro episode upload --dataset mydataset --dir ./episode_001
```

### With HuggingFace Datasets
