        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?

                    Try this :

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

                        Thank you, seems like that worked.

                        But now I am getting following error when I’m trying to run “encode.py”

                        Python 3.7.3 (/usr/bin/python3)
>>> %Run encode.py
Traceback (most recent call last):
  File "/home/pi/MagicMirror/modules/MMM-Face-Reco-DNN/tools/encode.py", line 5, in <module>
    from imutils import paths
ModuleNotFoundError: No module named 'imutils'
>>>

                        But when I’m installing “imutils” using “pip install imutils” I am getting no error, but following message:

                        Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Requirement already satisfied: imutils in ./.local/lib/python2.7/site-packages (0.5.3)

                        Any Idea how to fix that?

                        And to your best camera question for this module, I’m using the PiCamera Module v.2, but I can’t tell you how good its working, since the Face-Reco is not working yet…
