🔧 Troubleshooting

Common Issues

1. ❌ Nodes not appearing in ComfyUI

# Check if models are downloaded
python test_installation.py

# Download missing models
python download_models.py

# Restart ComfyUI completely

2. ❌ "ControlNet model not found" error

# Verify ControlNet models are in correct location
ls ComfyUI/models/controlnet/

# Should show these 4 files:
# control_v11p_sd15_scribble.pth
# control_v11f1p_sd15_depth.pth  
# control_v11p_sd15_normalbae.pth
# control_v11p_sd15_openpose.pth

# If missing, download them:
python download_models.py

3. ❌ Installation fails

# Check Python version
python --version  # Must be 3.8+

# Check available space (need 6GB+)
# Windows: dir
# Linux/Mac: df -h

# Manual dependency install
pip install torch torchvision --index-url https://download.pytorch.org/whl/cu121

4. ❌ GPU not detected

# Check CUDA
nvidia-smi
python -c "import torch; print(torch.cuda.is_available())"

# Update GPU drivers if needed

5. ❌ Low performance

Enable GPU acceleration in settings
Reduce video resolution/quality
Increase cache size limits
Close other GPU-intensive applications
Run: python test_installation.py to check GPU memory

6. ❌ Memory issues

Reduce batch size in node configuration
Enable intelligent caching
Use FP16 precision if supported
Check available GPU memory: nvidia-smi
