## 🚨 Troubleshooting

### ❓ **Common Issues**

1. **PyTorch CUDA Issues**
   - ✅ **SOLVED**: Using PyTorch 2.9.0.dev with CUDA 12.8
   - Your RTX 5070 Ti is fully supported

2. **Audio Generation Fails**
   - ✅ **SOLVED**: All F5-TTS dependencies installed
   - Uses your fine-tuned 5.6GB model

3. **Ollama Model Not Found**
   - Run: `ollama create mindfull -f Modelfile_Mindfull`
   - Falls back to `mistral:7b` automatically

4. **Web API Not Accessible**
   - Check if port 5000 is free
   - Use `python mindfull_web_api.py` to start
