Error MMM-Facial-Recognition

[kms4381]

I tried to run MMM-Facial-Recognition, but it was blocked at this point.

Whoops! There was an uncaught exception...

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues

model.read(config.get("/home/pi/MagicMirror/modules/MMM-Facial-Recognition-Tools/training.xml"))

Is this the cause?
What should I do about this part?

my config.js is

{
	module: "newsfeed",
	position: "bottom_bar",
	classes: 'minsoo',
	config: {
		feeds: [
			{
				title: "New York Times",
				url: "http://www.nytimes.com/services/xml/rss/nyt/HomePage.xml"
			}
		],
		showSourceTitle: true,
		showPublishDate: true
	}
},
{
	module: 'MMM-Facial-Recognition',
	config: {
		recognitionAlgorithm: 1,
		lbphThreshold: 50,
		fisherThreshold: 250,
		eigenThreshold: 3000,
		useUSBCam: true,
		trainingFile: 'modules/MMM-Facial-Recognition-Tools/training.xml',
		interval: 2,
		logoutDelay: 15,
		users: ['minsoo'],
		defaultClass: "default",
		everyoneClass: "everyone",
		welcomeMessage: true
		}
},
]

};

/*************** DO NOT EDIT THE LINE BELOW ***************/
if (typeof module !== "undefined") {module.exports = config;}

I am anxiously waiting for your help.

[merttcoo]

Same problem to me . Did you find a solution ?

[sdetweil]

the readme says

To train the needed model use the MMM-Facial-Recognition-Tools.

wen you follow that link, it says

DEPRECIATED
This module is no longer supported. When it does work, the facial recognition methods used performed poorly.

there are a LOT of steps to execute to ‘train the model’

did u do that? (it creates the missing xml file)

[sdetweil]

to work on a user problem with one of my modules, I installed the https://github.com/nischi/MMM-Face-Reco-DNN module, and it was very complex and time consuming. (I installed in on my linux PC, not my pi)

[merttcoo]

what do you suggest ?

[sdetweil]

@merttcoo i don’t have a recommendation. I don’t use this function

so you can try the steps to create the model with the one you have partly installed,
or you can try the other one.
