Running on Raspberry Pi 3 and Pi-camera on Raspian buster latest. When testing the MMM-Face_Reco-DDN facerecognition.py module stand alone, faces are correctly identified in the camera and [names] output. However, when running from MagicMirror, the error occurs, and it looks like it is complaining about improper use of a boolean operator in the code. I don’t know python data class rules, but if this was a code issue, surely others woudl have seen it in this module? Do I maybe have a lost data class object or something? PythonSherrError: TypeError: ‘<’ not supported between instances of ‘numpy.ndarray’ and ‘str’ is received, and the python traceback seems to point to the facerecognition.py module.```

@majik655 Thank-you, and interesting that you mentioned the MMM-Face-Reco-DDN module, because I gave up on the OCV3 module and moved to the DDN module. But, I’m getting an error in it that looks to be complaining about the use of a boolean operator (<) between different data types. The base facerecognition.py works just fine stand alone. But, when running with MagicMirror, the error occurs.

I’m working a new install of MagicMirror MMM-Facial-Recognition-OCV3 module on Raspberry Pi Buster 10 with CV2 version 4.3.0. When running the training module, it ends with the message FATAL: OpenCV Major Version must be 3. Is there a known fix without backing CV2 back to version 3.x?
