    • 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?

    • Azure Cognitive Services API

      I’d like to integrate the Cognitive Services API from the Microsoft Azure Cloud.
      The API also detects emotions which can also be displayed. Something like “Hello John, you look happy today” would be a very cool output.
      Does anyone know if such a module already exists or if not where I should start to develop?
      Im very new but interested in this topic.
      Thanks for your help.
