I have an error happening when a face is detected. I made a post in the MM2 forum, and the only response I have so far is:
@KSumwalt it seems that python has added type checking, which it wasn’t using before.
there was another python related type checking problem a few days ago…
looks like the node_helper has launched the python script to compare the face files, and run into a problem checking the parms passed to it.
I have loaded the MMM-Face-Reco-DNN and even used the i_face_recognition.py from https://www.pyimagesearch.com/2018/06/25/raspberry-pi-face-recognition/ with the encodings file generated from the MMM-Face-Reco-DNN instructions and had that .py file recognize faces. So I backed everything out of my config file except the default MMM-Face-Reco-DNN settings from the instructions and when I manually start MM2 everything looks fine. I am running on a Raspberry Pi 4. I did install a different facial recognition module, but it was not in the config file and decided not to use it when I saw it only recognized 1 person. When I step in front of the camera, this comes up in the terminal where I manually started MM2:

There is a little more information at the linked forum post, include the config file if you need it. Is there any assistance you can provide?
