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 ？

Whoops! There was an uncaught exception…

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.
