I have installed all modules and dependencies for face recognition. but if i want to start this: python facerecognition.py the following error message appears:

pi@raspberrypi:~/MagicMirror/modules/MMM-Facial-Recognition-Tools $ python facerecognition.py
Remember to set the name list environment variable FACE_USERS
Using default FACE_ALGORITM: 1
Loading training data…
mmal: mmal_vc_component_create: failed to create component ‘vc.ril.camera’ (1:ENOMEM)
mmal: mmal_component_create_core: could not create component ‘vc.ril.camera’ (1)

But with “fswebcam image.jpg” I can shoot some photos with SSH.

Any ideas?
Thanks very much for your help.

Greetings
Michael
