I got a issue when i add the facial module. the Facial-tools work fine, it’s seems like python script issues.

Could anyone help me with this issue ？

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues

@MichiMauch Are You using Webcam ?

naktah

specify your user labels in the environment with

export FACE_USERS=Alice,Bob,Casey,Doug

im not sure what to do with this. do i have to write this in the terminal? because everytime i restart my pi, the facial recognition doesnt recognize my face

sdetweil

@naktah u need to put that in your logon profile

naktah

@sdetweil im not sure how to do that. can you show me how? im pretty much new to this stuff and this issue has been bothering me for days now.

Sneek

@naktah after writing the following command in the terminal:

python tools.train.py

you get some output with the users you have setup (remember the order). Assuming it gives you Alice,Bob,Casey,Doug, then you run this in the terminal:

export FACE_USERS=Alice,Bob,Casey,Doug
