Secondly, thanks for your help! According to your method, I installed python-shell 0.4.0 and resolved the issue of “PythonShell is not a constructor” .

Now I had another issue in the followed steps.

I have installed and configured MMM-Facial-Recognition-Tools, MMM-Facial-Recognition and MMM-ProfileSwitcher. I passed the facerecognition.py test:

pi@MagicMirror2:~/MagicMirror/modules/MMM-Facial-Recognition-Tools $ export FACE_ALGORITHM=1
pi@MagicMirror2:~/MagicMirror/modules/MMM-Facial-Recognition-Tools $ export FACE_USERS=
pi@MagicMirror2:~/MagicMirror/modules/MMM-Facial-Recognition-Tools $ export FACE_USERS=Xueping
pi@MagicMirror2:~/MagicMirror/modules/MMM-Facial-Recognition-Tools $ 
pi@MagicMirror2:~/MagicMirror/modules/MMM-Facial-Recognition-Tools $ export FACE_ALGORITHM=1
pi@MagicMirror2:~/MagicMirror/modules/MMM-Facial-Recognition-Tools $ export FACE_USERS=Xueping
pi@MagicMirror2:~/MagicMirror/modules/MMM-Facial-Recognition-Tools $ python facerecognition.py 
['Xueping']
Using FACE_ALGORITM: 1
Loading training data...
Training data loaded!
Strong:Xueping
Strong:Xueping
Strong:Xueping
Strong:Xueping
Strong:Xueping
Strong:Xueping

Now I added the configuration in config.js as followings:

modules: [
		{
            module: 'MMM-Logging',
            classes: 'default everyone',
            config: {
            }
        },

		{
			module: "alert",
			classes: 'default everyone'
		},
		{
			module: "updatenotification",
			position: "top_bar",
			classes: 'default everyone'
		},

		{
			module: "compliments",
			position: "lower_third",
			classes: 'Xueping',
			config: {
				compliments: {
					anytime: [
						"Hello！THIS IS TESTING！"
					],
				}
			}
		},
		{
			module: "clock",
			position: "top_left",
			classes: 'everyone'
		},
		{
			module: 'MMM-Facial-Recognition',
			position: "top_right",
			config: {
				// 1=LBPH | 2=Fisher | 3=Eigen
				recognitionAlgorithm: 1,
				lbphThreshold: 50,
				fisherThreshold: 250,
				eigenThreshold: 3000,
				alwaysShowLeave: false,
				useUSBCam: false,
				trainingFile: '/home/pi/MagicMirror/modules/MMM-Facial-Recognition-Tools/training.xml',
				interval: 2,
				logoutDelay: 30,
				users: ['Xueping'],
				defaultClass: "default",
				everyoneClass: "everyone",
				welcomeMessage: true,
			}
		},
		{
			module: 'MMM-ProfileSwitcher',
			config: {
				// Disable the enter messages for everyone but me and Kevin
				enterMessages: {
					"Xueping": "Hello :D", // Kevin has a custom message
					"everyone": "Hello :D",
					"default": "No Users were detected"
				},
				// Everyone has a custom message
				leaveMessages: {
					// %profile% will be replaced with the correct name
					"everyone": "Hey %person%, already leaving?",
					// I have a custom and the default message
					//  this is not the same as everyone since we changed it
					"Xueping": ["Bye bye!"], 
					"default": "Goodbye"
				}
			}
		},
		{
			module: "MMM-ping",
			position: "bottom_right",
			classes: 'default',
			config: {
				colored: true,
				font: "xsmall",
				updateInterval: 1,
				hosts: [
					"192.168.1.1",
					"forum.magicmirror.builders"
				]
			}
		},

	]

When I run MagicMirror, the screen layout changed from default classes mode into user classes mode. the icons, which is in default classes mode, disappeared as I want. BUT in user classes mode, the very module (compliments) did not appeared! the whole screen is still black.

The whole process log is as following:

anyone an idea?

Regards,
Wolfgang

Still have a lot of tinkering to do, but this solved the annoying issue I caused.

Thank you kindly for the help.

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.

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

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)

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:

config.js:
