🎨 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
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:

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
2. Navigate to "Training" tab
3. Click "Import Dataset" → "From HuggingFace"
4. Select dataset
5. Use for training

Download via Code:

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:

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
