MMM-Face-Reco-DNN , Blank Screen error

[oberk]

Hi, I am very new to Rasp Pi. Would be grateful for your help.

I have installed MMM-Face-Reco-DNN module,
When I run the script, I got Magic mirror screen with modules, screen for 1 sec, and then a blank screen.

When I look at camera, camera recognizes me, and
I got the message “Hello oberk” on mid top of a blank screen, but no other modules. And then message disappears and I end up with a blank screen, again

Would appreciate your help.

@oberk so, its sounds like you have a short time to logoff

and then you don’t have the classes: configured in config.js on the modules that match the person identifier

@sdetweil

You are right, thank you,
Sorted.

@oberk Hey, hope you are well!

How did you get this to work correctly?
I have successfully installed everything and my face gets detected successfully. I get the notification pop up saying I’m detected but it doesn’t switch profiles. The modules all have classes assigned too.

Am I missing something?

Thanks,
Alfie

@N3UR0515 show a couple modules w classes defined

@sdetweil Hey, thanks for the quick reply.

Here is my full config, it’s a fresh install with just the 2 modules installed.

/* Config Sample

 * For more information on how you can configure this file

@N3UR0515 and what is the user name detected

[N3UR0515]

@sdetweil The username detected is alfie.

Here is a log extract confirming it successfully detects me:

@N3UR0515 you cant have profile switcher AND facereco. they do the same thing

so, only newsfeed should show for alfie

[N3UR0515]

@sdetweil Thank you so much! Knew I’d done something wrong.

Not sure why I thought they had to be used together.

Thanks for the speedy responses👊

[sdetweil]

@N3UR0515 you would use profileswitcher if you had something else advising which profile to use and nothing else doing that function

facereco is doing it all
