## 🛠️ **Troubleshooting**

### **Backend Issues**
```bash
# Check if models are loaded
curl http://localhost:8000/health

# Check GPU availability
python -c "import torch; print(torch.cuda.is_available())"
```

### **Frontend Issues**

#### **Dependency Resolution Error**
If you get `ERESOLVE unable to resolve dependency tree`:
```bash
# Clear cache and reinstall with legacy peer deps
rm -rf node_modules package-lock.json
npm install --legacy-peer-deps
```

#### **Alternative Installation**
```bash
# Use pnpm instead of npm
npm install -g pnpm
pnpm install
```

#### **Force Clean Install**
```bash
# Clear all caches
npm cache clean --force
rm -rf node_modules package-lock.json
npm install --legacy-peer-deps
```

### **Model Loading Issues**
- Ensure all trained models exist in `trained_models/`
- Check GPU memory (8GB RTX 4060 recommended)
- Verify Python dependencies are installed
