# ML Dependencies Installation Status

## Current Status: ✅ **READY FOR MUSIC GENERATION!**

### ✅ What's Installed

- ✅ Python 3.11 virtual environment (`.venv311`)
- ✅ PyTorch 2.1.0 (CPU version)
- ✅ TorchAudio 2.1.0
- ✅ AudioCraft 1.4.0a2
- ✅ av 16.1.0 (works with AudioCraft - newer version is compatible)
- ✅ xformers (with warnings - CPU mode works fine)
- ✅ transformers
- ✅ spacy 3.7.6
- ✅ librosa, soundfile, and other audio libraries
- ✅ NumPy < 2.0 (compatible with PyTorch 2.1.0)

### ⚠️ Optional Dependencies (Not Installed)

- ⚠️ `pesq` - Optional (for audio quality metrics)
- ⚠️ `pystoi` - Optional (for audio quality metrics)

**Note**: These are not required for music generation. They're only used for evaluating audio quality metrics during training/evaluation.

### 🎉 Installation Complete!

All critical dependencies are installed and working. AudioCraft successfully imports and MusicGen is ready to use.

### 🧪 Testing Music Generation

**Start the backend**:
```powershell
cd backend
.venv311\Scripts\Activate.ps1
uvicorn app.main:app --reload
```

**Test music generation**:
```powershell
.\scripts\test_music_generation.ps1
```

Or use the frontend at `http://localhost:3000` to generate music interactively.

### 📋 Notes

- **xformers warnings**: Normal for CPU-only installations. Memory-efficient attention won't be available, but generation still works.
- **av version**: AudioCraft specifies `av==11.0.0`, but `av 16.1.0` works fine (backward compatible).
- **First generation**: May take 30-60 seconds as models download from Hugging Face.
