Facial Recognition - Where do elements go go?

[KirAsh4]

Yeah, you’d have to ask the module’s author for help, or others who use this module.

From one rookie to another:

I had to add ‘classes’ in config.js with ‘default’, ‘for_all’ or person’s name in all modules I wanted to be shown.

Eksample:

            {
                    module: 'alert',
                    classes: 'default'
            },

[KirAsh4]

That should not be necessary. If you had to do that and MM² loaded up after that, then there’s something seriously wrong with the module for it to “leak” like that.

[paviro]

It is because I hide every module that is not for everyone at startup.
default modules are for users that are not recognized or if there is no user at all.
for_all are modules shown for everyone.

[Cato]

@paviro Would it make more sence to say that no “classes” equals to “default” and therefore would be visible?

[paviro]

@Cato i think there was a reason why I did not do that but if you would like to look into it you can send me a pull request! :)

Hello,

I’m trying to use facial trainer but i got this error ( when executing python capture.py)

What do you want to do?
[1] Capture training images from webcam
[2] Convert ‘*.jpg’ pictures from other cameras to training images
–> 1

Enter the name of the person you want to capture or convert images for.
–> plumcraft
Images will be placed in ./training_data/plumcraft

Starting process…

Capturing positive training images.
Press enter to capture an image.
Press Ctrl-C to quit.

Capturing image…

I’m using a raspberry pi 3 with pi camera.

Looking forward to use this module.

Thanks

I have the same error. Can everybody help me? I also use Raspberry Pi 3 with pi Camera.

Thanks a lot!
