      Got another problem. My picam is not able to open. I am using opencv 3.3.

      Remember to set the name list environment variable FACE_USERS
      Using default FACE_ALGORITM: 1
      Traceback (most recent call last):
      File "facerecognition.py", line 30, in 
      camera = config.get_camera(preview)
      File "/home/pi/MagicMirror/modules/MMM-Facial-Recognition-Tools/lib/config.py", line 101, in get_camera
      return webcam.OpenCVCapture(device_id=0)
      File "/home/pi/MagicMirror/modules/MMM-Facial-Recognition-Tools/lib/webcam.py", line 29, in __init__
      self._camera.open()
      TypeError: Required argument 'device' (pos 1) not found
      

      any suggestions?

        Hello!

        I have an problem wirth the Facial Regonition Module. I have tried it with the PiCam and an normal webcam. It worked not really good with die webcam and after i’ve tried it with die PiCam it doesn’t work any more. I’ve updatet the config.js.

        This is the npm output:

        0_1510996315204_mmm.PNG

        config.js:

        On the mirror nothing is shown. {
        			module: 'MMM-Facial-Recognition',
        			config: {
        				// 1=LBPH | 2=Fisher | 3=Eigen
        				recognitionAlgorithm: 1,
        				// Threshold for the confidence of a recognized face before it's considered a
        				// positive match.  Confidence values below this threshold will be considered
        				// a positive match because the lower the confidence value, or distance, the
        				// more confident the algorithm is that the face was correctly detected.
        				lbphThreshold: 50,
        				fisherThreshold: 250,
        				eigenThreshold: 3000,
        				// force the use of a usb webcam on raspberry pi (on other platforms this is always true automatically)
        				useUSBCam: true,
        				// Path to your training xml
        				trainingFile: 'modules/MMM-Facial-Recognition-Tools/training.xml',
        				// recognition intervall in seconds (smaller number = faster but CPU intens!)
        				interval: 1,
        				// Logout delay after last recognition so that a user does not get instantly logged out if he turns away from the mirror for a few seconds
        				logoutDelay: 15,
        				// Array with usernames (copy and paste from training script)
        				users: ['Jenny'],
        				//Module set used for strangers and if no user is detected
        				defaultClass: "default",
        				//Set of modules which should be shown for every user
        				everyoneClass: "everyone",
        				// Boolean to toggle welcomeMessage
        				welcomeMessage: true
        			}
        

        Any suggestions?

          @mc_landin I’m at this stage as well! for some reason the classes dont change whats displayed when a new face is seen. So in this example the “default” is seen all the time and then when a generic face is seen then the “everyone” class isnt shown. Has anyone got this working?

                      {
                              module: "updatenotification",
                              position: "top_bar",
                              classes: 'default'
                      },
                      {
                              module: "clock",
                              position: "top_left",
                              classes: 'everyone'
                      },
                      {
                              module: 'MMM-Facial-Recognition',
                              config: {
                                      recognitionAlgorithm: 1, // 1=LBPH | 2=Fisher | 3=Eigen

              Hi All, I have found out that if you want to use your USB webcam for training you can update the file https://github.com/paviro/MMM-Facial-Recognition-Tools/blob/master/lib/config.py in the appropriate directory with the following. for some reason it doesnt seem to want to fall over to the webcam so I just commented out the pi web cam and added the usb one.

              def get_camera(preview=True):
                  try:
              #        from . import picam
              #        capture = picam.OpenCVCapture(preview)
              #        capture.start()
              #        return capture
                      from . import webcam
                      return webcam.OpenCVCapture(device_id=0)
                      capture.start()
                      return capture
                  except Exception:
                      from . import webcam
                      return webcam.OpenCVCapture(device_id=0)

                OK after lots and lots of trial and error I hope this helps people… these are the settings and results I had and as far as I can tell the everyone setting doesnt do what I would expect…

                I don’t hink you have a way of identifying a stranger and do something specific for them?

                defaultClass: "default", //Module set used for strangers and if no user is detected
                

                It looks like when everyone is specified on its own then the logic doesnt seem to work. See classes: “everyone” below…

                                                users: ['martin'], // Array with usernames (copy and paste from training script)
                                                defaultClass: "default", //Module set used for strangers and if no user is detected
                                                everyoneClass: "everyone", //Set of modules which should be shown for every user
                                                welcomeMessage: false // Boolean to toggle welcomeMessage
                                        }
                                },
                                {
                                        module: "clock",
                                        position: "top_left",
                                        classes: "default" // displays with no face detection (OK) - not displayed when martin detected (OK) - displayed with no specific user detected (OK?)
                                },
                                {
                                        module: "clock",
                                        position: "top_right",
                                        classes: "default everyone" // displays with no face detection (OK) - displayed with no specific user and martin (OK)
                                },
                                {
                                        module: "clock",
                                        position: "bottom_right",

                                },

                                        classes: "everyone" // never displays (??? I would expect this to display when Martin is detected - or any other user)
                                },
                                {

                  Hi,

                  I use your Facial Recognition modul. I have create some user and everything work fine.

                  But now I install MMM-Motion-Detection modul. I works fine, too. But if I use this modul your modul didn´t work. When I cut off the MMM-Motion-Detection module from config.js and start again your modul will work fine again.

                  Can someone help me?

                  greets gismo

                    @paviro I have the same problem like @shashank, but I don’t figure out any mistake… the trainingfile is in the right direction… It doesn’t work with PiCam and with an webcam neither…

                      Sorry for spaming,

                      but I tried to refresh everything. So I installed the Rasbian new, the Magic Mirror, the Facial Recognition and the Tools. It worked… ONCE. After rebooting the system I have the same error as bevor:

                      It load training data and select the PiCam and then it doesn’t go on. No error-message.

                      Any idea which component was active when I reinstalled everything and isn’t active after rebooting?
                      The camera is enabled.
