🐛 Troubleshooting
Common Issues
1. Model Loading Error
- Ensure model files exist in
weights/detection/
- Check file permissions
- Verify model integrity
2. GPU Not Detected
- Install CUDA-compatible PyTorch
- Check GPU drivers
- Verify CUDA availability
3. Webcam Access Denied
- Check browser permissions
- Ensure HTTPS connection
- Test with different browsers
1. Increase Speed
- Use smaller models (YOLOv8n/s)
- Reduce input resolution
- Lower confidence threshold
2. Improve Accuracy
- Use larger models (YOLOv8m/l/x)
- Increase input resolution
- Fine-tune confidence threshold
