```

## Release Steps

### Step 1: Prepare the Data

```bash
cd huggingface_release

# Convert existing parquet files to HF format
python prepare_release.py \
    --input_dir ../scripts/data/parquet_files_v5 \
    --output_dir v20251201 \
    --version v20251201
```

### Step 2: Create Assets

```bash
# Generate banner and sample images
python create_sample_images.py \
    --input_dir ../scripts/data/parquet_files_v5 \
    --output_dir assets
```

### Step 3: Upload to HuggingFace

```bash
# Set your HuggingFace token
export HF_TOKEN="your_token_here"

# Upload using folder method (preserves structure)
python upload_to_hf.py \
    --repo_id your-org/LookBench \
    --data_dir v20251201 \
    --method api

# Or upload using datasets library (creates proper configs)
python upload_to_hf.py \
    --repo_id your-org/LookBench \
    --data_dir v20251201 \
    --method datasets
```

## Versioning Strategy

LookBench uses date-based versioning: `vYYYYMMDD`

| Version | Date | Changes |
|---------|------|---------|
| v20251201 | Dec 2024 | Initial release |
| v20250301 | Mar 2025 | (future) Updated gallery |

To add a new version:
1. Create a new versioned directory (e.g., `v20250301/`)
2. Update `README.md` with new version info
3. Add new config entries in the YAML frontmatter
4. Keep old versions for reproducibility

## Dataset Card (README.md)

The README.md serves as the dataset card displayed on HuggingFace. Key sections:

1. **YAML Frontmatter**: Metadata, configs, features
2. **Overview**: Description and key features
3. **Dataset Structure**: File organization
4. **Data Schema**: Column descriptions
5. **Statistics**: Sample counts and distributions
6. **Evaluation Metrics**: How to evaluate
7. **Leaderboard**: Model rankings
8. **Citation**: BibTeX entry

## Image Display on HuggingFace

For images to display in the HuggingFace viewer:

1. **Parquet format**: Store images as `{'bytes': image_bytes, 'path': None}`
2. **Features definition**: Use `Image()` type in the schema
3. **Dataset card images**: Reference with `![alt](assets/image.png)`

### Parquet Image Format

```python
# Correct format for HF image display
record = {
    'image': {'bytes': image_bytes, 'path': None},
    'category': 'bag',
    ...
}
```

### Dataset Card Images

```markdown
<!-- In README.md -->
![Banner](assets/lookbench_banner.png)
![Samples](assets/samples_aigen_streetlook.png)
```

## Loading the Dataset

After upload, users can load the dataset:

```python
from datasets import load_dataset

# Load a specific task
ds = load_dataset("your-org/LookBench", "aigen_streetlook")

# Access splits
query = ds["query"]
gallery = ds["gallery"]

# View sample
print(query[0])
query[0]["image"]  # Returns PIL Image
```

## Updating the Leaderboard

To update the leaderboard:

1. Run evaluation on your model
2. Submit results via GitHub issue or PR
3. Update the leaderboard table in README.md

## Troubleshooting

### Images not displaying
- Ensure images are in `{'bytes': ..., 'path': ...}` format
- Check that Features specifies `Image()` type
- Verify parquet was saved with correct schema

### Upload fails
- Check HF_TOKEN is valid and has write access
- Ensure repo exists and you have permissions
- Try uploading in smaller batches

### Dataset won't load
- Verify parquet files are valid: `pd.read_parquet(file)`
- Check config names match directory structure
- Ensure all required columns are present
