SOLVED MMM-Face-Reco-DNN doesn't work
-
Everything works fine without the module integration in the MagicMirror/config.js but with the additional text there is no response and the monitor is black. I installed python in a virtual environment but I changed the pythonpath accordingly so I don’t know if this is the problem.
If somebody could kindly show their config.js with the module enabled this would be extremly helpful. -
@Antagonist what does the developers window show?

In between it all it says, that cv2 is not found. Your cv2 is probably not linked to your python 3.
-
@Blauenfeldt Ahh that doesn’t sound very good. I’ve installed python in an virtual environment. Do you know a solution for this problem? Thanks a lot!

@Antagonist did u follow the instructions for the module?

@Antagonist which python version… different solutions fror 2.7 or 3.x
see
https://stackoverflow.com/questions/19876079/cannot-find-module-cv2-when-using-opencv
ps… that is result of a google search on the error… I don’t know anything about this technology (python/cv2)

@sdetweil I have Python version 3.7.3.
And I have OpenCV 4.1.1 installed:(cv) pi@raspberrypi:~ $ python Python 3.7.3 (default, Apr 3 2019, 05:39:12) [GCC 8.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import cv2 >>> cv2.__version__ '4.1.1'Thanks for your help!

@Antagonist but it doesn’t work in module, which means the path is not set properly
