    • RE: MMM-Face-Reco-DNN doesn't work

      Everything works. I’m just stupid as hell and didn’t add the classes to the other modules.

      @sdetweil unfortunately there is nothing which would help.
      Has anybody else an idea?

    • RE: MMM-Face-Reco-DNN doesn't work

      @sdetweil Ok but where can I adjust the path to link it properly with opencv? And thank you, you have been a great help so far!

    • RE: MMM-Face-Reco-DNN doesn't work

      @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!

    • RE: MMM-Face-Reco-DNN doesn't work

      @sdetweil Yes, I think I installed all dependencies accordingly and followed this instruction for opencv.

    • RE: MMM-Face-Reco-DNN doesn't work

      @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!

      I don’t know but I’ve attached the error log and you can find my config.js above. Thank you and sorry for the long message.

    • 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.

    • RE: Azure Cognitive Services API

      @Sean Thank you. I assume this would’t make a lot of sense since opencv is free and azure has a limited number of recognitions. Nevertheless an emotion detector would be cool. Because of your fancy Module Developer Icon I think you have a lot more experience with this stuff so do you know if something like this currently exists?
