MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?)

Please I would appreciate any help
thank you in advance

@xchribiza sounds like missing file permission

detuma

Is your training file in /modules/MMM-Facial-Recognition/ ? (it is probably in /modules/MMM-Facial-Recognition-Tools/ ), check the path again, and do some change in your config.js

@strawberry-3.141 How do I fix this ?? Any idea ?

xchribiza

@detuma I have copied the training.xlm to both locations (tools etc) and checked with the both location in config.js
nothing happended.
It seems like the camera is not opening (i use a usbcamera)

I’m pretty sure you still wrote a wrong path, check this post https://forum.magicmirror.builders/topic/62/face-recognition-file-can-t-be-opened-for-writing/5
