        Depends on how you define working fine…The face recognition is working quite good, setting it up is easy with the advice you get in this thread. For me it’s just the “slow” reaction to activate the display which is an issue. But I’m optimistic that there is a way to solve it and I have a special environment with a display which hasn’t CEC control.

            I am turning on the monitor using a PIR sensor and it is instant. Keep in mind that it also depends on your monitor, some are slower to respond - this is my second monitor, the first one was very slow to respond to any HDMI related commands.

              I have a new strange error and I think it’s just if I restart mm with “pm2 restart mm”. If I reboot my pi, everything is fine.

                I get this too, when my PI can’t connect to the camera. I know that, because if i use
                Raspistill -o s.jpg
                I will get an error there too. A reboot seems to fix it though. I don’t know what makes it happen, but i suspect the cable.

                  @Blauenfeldt the python code returns an error, but the module does not expect it, and fails.

                    Will this work if the camera is rotated? If not, can you tell me where I need to change the code?

                      when im trying to install the face_recogtnition I’m getting this error code:

                      Does anybody know how to fix this/what is causing this?
                      Sorry if it’s obvious, im a super noob with this kind of stuff

                      Cheers

                        Try this :

                        pip --no-cache-dir install face_recognition
                        -python setup.py install
