Instead of this wrapper, I recommend using native ComfyUI implementation of brushnet:
https://github.com/nullquant/ComfyUI-BrushNet
Either use the Manager and it's install from git -feature, or clone this repo to custom_nodes and run:
pip install -r requirements.txt
or if you use portable (run this in ComfyUI_windows_portable -folder):
python_embeded\python.exe -m pip install -r ComfyUI\custom_nodes\ComfyUI-BrushNetWrapper\requirements.txt
Models are automatically downloaded from here: https://huggingface.co/Kijai/BrushNet-fp16/tree/main
to ComfyUI/models/brushnet
