Facerecognition doesnt work

[Mickan1994]

Hey, I just got everything installed on a virtual environment but even if I set classes and everything, my Face won't be recognized. I just wanted to try the facerecognition.py directly but as soon as I run it I get the following error:

{"status": "loading encodings + face detector..."} {"status": "starting video stream..."} Traceback (most recent call last): File "/home/pi/MagicMirror/modules/MMM-Face-Reco-DNN/tools/facerecognition.py", line 79, in if args["source"].isdigit(): AttributeError: 'int' object has no attribute 'isdigit'

I'm not able to find anything wrong, I just installed everything step for step but its not working.

Hi

Hmm strange, i installed it a week ago with the newest openCV version and it runs fine. How your config looks like?

Hi, I don't know how and why, because I'm not that fit in python but with much searching I was able to get it working by changing the code

#if args["source"].isdigit():

to

if str(args["source"]): src = int(args["source"])

I don't know if this code snippet in facerecognition.py is wrong and need to be updated but this is the way I got it fixed...

I had the same error and @Mickan1994 's suggestion seemed to solve one issue but now I am getting further errors when trying to fun facerecognition.py to test things out.

I will leave my last comment in case others come across the same thing. The error I received was due to having MagicMirror running at the same time when trying to run facerecognition.py. Stopping MagicMirror then running it worked as expected. I can confirm @Mickan1994 fix worked.
