MMM-Face-Reco-DNN doesn't work

[Blauenfeldt]

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!

[sdetweil]

@Antagonist did u follow the instructions for the module?

https://github.com/nischi/MMM-Face-Reco-DNN#install-dependencies

[Antagonist]

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

[sdetweil]

@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)

[Antagonist]

@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

[Antagonist]

@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!

[sdetweil]

@Antagonist I don’t know, read this

https://pypi.org/project/opencv-python/

[Antagonist]

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

[Blauenfeldt]

You need to go into your virtual environment, and link cv2 and python 3 together there (can’t remember which way it is), just like you did outside the environment.

[Antagonist]

@Blauenfeldt I already did this:

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