## Quick Start

### Installation

```bash
pip install huggingface_hub
```

### Download Full Dataset

```python
from huggingface_hub import snapshot_download

dataset_path = snapshot_download(
    repo_id="VisGym/inference-dataset",
    repo_type="dataset",
)
```

### Download Specific Subsets

```python
from huggingface_hub import snapshot_download

# Download only test sets (small, no large assets)
dataset_path = snapshot_download(
    repo_id="VisGym/inference-dataset",
    repo_type="dataset",
    allow_patterns=["test_set_easy/**", "test_set_hard/**"],
)

# Download only easy difficulty
dataset_path = snapshot_download(
    repo_id="VisGym/inference-dataset",
    repo_type="dataset",
    allow_patterns=["*_easy/**"],
)
```

### Using the Loader Script

```bash
# Download everything
python load_from_hf.py --output_dir ./inference_dataset

# Download only test sets (no large assets)
python load_from_hf.py --output_dir ./inference_dataset --subset test_sets

# Download only easy difficulty
python load_from_hf.py --output_dir ./inference_dataset --subset easy
```

## File Formats

### Test Set Files (JSONL)

Each line in the JSONL files contains an episode specification:

```json
{"seed": 1803372, "env_id": "maze_2d/hard", "episode_seed": 1052368083, "extra_state": null}
```

### Initial State Files (JSON)

JSON files containing the initial state for reproducible episode starts:

```json
{
  "object_path": "000-156/fa3dad5169784cec85b96682231e3f44.glb",
  "secret_yaw": 1.098,
  "secret_pitch": 0.487,
  ...
}
```

## Usage with VLM-Gym

```python
from pathlib import Path
import json

# Load test episodes
test_file = Path(dataset_path) / "test_set_easy" / "maze_2d__easy" / "*.jsonl"
for jsonl_file in test_file.parent.glob("*.jsonl"):
    with open(jsonl_file) as f:
        for line in f:
            episode = json.loads(line)
            env_id = episode["env_id"]
            seed = episode["seed"]
            episode_seed = episode["episode_seed"]
            # Use with VLM-Gym inference runner
```
