Hey, @Scatman60! I'm here to help you with any bugs, questions, or contributions you have. Let's tackle this issue together!

The issue you're experiencing with the installation of custom nodes in ComfyUI is due to missing Python modules, specifically cv2 and numba. These modules are required by the custom nodes you're trying to install.

To resolve this issue, you need to install the missing modules. You can do this by running the following commands in your terminal or command prompt:

  1. For cv2 (OpenCV):

    pip install opencv-python

  2. For numba:

    pip install numba

Make sure you run these commands in the environment where ComfyUI is installed. After installing these dependencies, try reinstalling the custom nodes. This should resolve the issue with the blank window during the installation process.

To continue talking to Dosu, mention @dosu.
