MMM-Face-Reco-DNN (No module named 'face_recognition')

[Zinkeler]

Hello everyone,
I installed MMM-Face-Reco-DNN according to the instructions and have been trying to find the error for days now.
There were no error messages during installation.

I carried out the installation with “python3 -m venv ~/python-facereco” and also added the entry “source ~/python-facereco/bin/activate” to the end of the ~.bashrc.

Still I always get: "ModuleNotFoundError: No module named 'face_recognition’
 at PythonShell.parseError (/home/ralph/MagicMirror/modules/MMM-Face-Reco-DNN/node_modules/python-shell/index.js:303:21)
 at terminateIfNeeded (/home/ralph/MagicMirror/modules/MMM-Face-Reco-DNN/node_modules/python-shell/index.js:193:32)

 ----- Python Traceback -----
 File “/home/ralph/MagicMirror/modules/MMM-Face-Reco-DNN/tools/recognition.py”, line 1, in 
 import face_recognition { ".

Can someone help me?

@Zinkeler just add the source command to the mm.sh

[sdetweil]

@Zinkeler i think this is because the install sets up a python virtual environment. and you have to enable that before you start MagicMirror

[Zinkeler]

@sdetweil I thought I did that with the entry in the /.bashrc!?
“source ~/python-facereco/bin/activate”
is that a mistake?

[sdetweil]

@Zinkeler usually the venv folder names are preceded by a dot (are hidden on linux)

@sdetweil
Sorry, but i don´t find my mistake (there is no dot).
I think the venv is startet: (python-facereco)

@Zinkeler and it depends. if the bash session will be visualized, then bashrc is used. if not (like MagicMirror is started by pm2) then its another session script. don’t remember its name
BUT bashrc is NOT used

see point 3 here

@Zinkeler just add the source command to the mm.sh

@sdetweil
I try to get it to work over the course of many days and hours, and then I write to you and solve the problem in a few chat rounds.
Thank you very much, you helped me a lot.

@Zinkeler glad you go it!
