## 🐛 Troubleshooting

### Common Issues

#### Models Not Loading
- **Cause**: Network connectivity or model URL issues
- **Solution**: Check internet connection, try refreshing the page

#### Slow Performance
- **Cause**: Large model files, limited resources
- **Solution**: Use MobileNetV2 for faster results, or try fewer models at once

#### Upload Errors
- **Cause**: Unsupported file format or size
- **Solution**: Convert to JPG/PNG, ensure file size < 10MB

#### Out of Memory
- **Cause**: Multiple large models loaded simultaneously
- **Solution**: Select fewer models, refresh the page to clear cache

### Getting Help

- **Check Logs**: Look for error messages in the interface
- **Try Different Models**: Some models may be temporarily unavailable
- **Refresh Page**: Clears model cache and resets the application
- **Contact Support**: Open an issue on the repository
