# 🎵 LEMM Training Data Repository

Central storage for all LEMM training artifacts:
- **LoRA Adapters** - User-trained model adaptations
- **Training Datasets** - Prepared and curated audio datasets

Part of the [LEMM (Let Everyone Make Music)](https://huggingface.co/spaces/Gamahea/lemm-test-100) project.

## 🎨 LoRA Adapters (`loras/`)

Each LoRA is packaged as a ZIP file containing:

- **`final_model.pt`** - Trained LoRA weights (PyTorch checkpoint)
- **`config.yaml`** - Training hyperparameters and settings
- **`metadata.json`** - Training statistics, timestamps, dataset info
- **`README.md`** - Documentation and usage instructions

### How to Use

**Download in LEMM:**
1. Go to [LEMM Space](https://huggingface.co/spaces/Gamahea/lemm-test-100)
2. Navigate to "LoRA Management" tab
3. Click "Sync from HuggingFace"
4. Select LoRA from dropdown
5. Use in generation or continue training

**Download via Code:**
```python
from huggingface_hub import hf_hub_download
import zipfile

# Download LoRA ZIP
zip_path = hf_hub_download(
    repo_id="Gamahea/lemmdata",
    repo_type="dataset",
    filename="loras/jazz-v1.zip"
)

# Extract
with zipfile.ZipFile(zip_path, 'r') as zipf:
    zipf.extractall("./my_loras/jazz-v1")
```

## 📊 Training Datasets (`datasets/`)

Each dataset is packaged as a ZIP file containing:

- **`dataset_info.json`** - Metadata (size, format, split ratios)
- **`train/`** - Training audio files
- **`val/`** - Validation audio files

### Supported Formats

- **Audio**: WAV, MP3, FLAC, OGG
- **Sample Rate**: 44.1kHz or 48kHz recommended
- **Channels**: Mono or Stereo

### How to Use

**Download in LEMM:**
1. Go to [LEMM Space](https://huggingface.co/spaces/Gamahea/lemm-test-100)
2. Navigate to "Training" tab
3. Click "Import Dataset" → "From HuggingFace"
4. Select dataset
5. Use for training

**Download via Code:**
```python
from huggingface_hub import hf_hub_download
import zipfile

# Download dataset ZIP
zip_path = hf_hub_download(
    repo_id="Gamahea/lemmdata",
    repo_type="dataset",
    filename="datasets/gtzan_prepared.zip"
)

# Extract
with zipfile.ZipFile(zip_path, 'r') as zipf:
    zipf.extractall("./my_datasets/gtzan_prepared")
```

## 🚀 Contributing

### Upload LoRA

Train a LoRA in [LEMM Space](https://huggingface.co/spaces/Gamahea/lemm-test-100):
1. Prepare or select a dataset
2. Configure training parameters
3. Start training
4. LoRA automatically packaged as ZIP and uploaded to `loras/{your-lora-name}.zip`

### Upload Dataset

Prepare a dataset and export:
1. Upload audio files to LEMM
2. Use dataset preparation tools
3. Export as prepared dataset
4. Dataset packaged as ZIP and uploaded to `datasets/{your-dataset-name}.zip`
