Same here, I’m getting the following errors on python tools.facerecognition.py

Change in capture.py

from config import ToolsConfig -> from .config import ToolsConfig

@SdeGeata

Hey @Nischi! I got it going!!!

Two things fixed it. The first was a directory error that was preventing capture. Fixed with:

in capture.py:

from config import ToolsConfig -> from .config import ToolsConfig

the second was an outdated PIP that wasn’t getting updated without SUDO that was giving me the error on Training.

sudo pip install future --upgrade

Both are fixed now and XML is generated. Next on to configuration. Thanks to all for your help.

@SdeGeata

Nevermind, I just fixed it! It was an outdated PIP that wasn’t getting updated without SUDO.

sudo pip install future --upgrade

@Sebi76 said in MMM-Facial-Recognition-OCV3 cant run toold.capture.py:

from .config import ToolsConfig

Well this solved the first of two problems for me. I have been getting the same error on capture since i installed. Thanks!

Now however, i get this error when trying to train:

Any idea what that’s about???

@SdeGeata

Does anyone have Autohide working properly on their set-up???

Re: MMM-MotionEye - surveillance video stream on your mirror!

So I have been all over these posts, and have seen the same question asked and answered a few times. I still however can not get the Autohide to unhide when motion is detected. I see the feed fine when it is unhidden. I get email notifications and photos uploaded, but the module will not show up. I have tried all kinds of options in the configs of both MotionEye and MM. Where am I going wrong???

Here are some pics of my settings:


@nischi

Sorry, i just saw your replies…

I am working on a Mac via VNC viewer and Terminal, all the software is installed on the Rpi 3 b+ directly though. I followed the installation steps on the page thoroughly, so I don’t know what could have gone wrong.

I did since then install MotionEye for another aspect I want to add to the mirror and I notice that it adds “boxes” around detected movement - I don’t think it does this normally, but rather is related to the OCV install; only the recognition wouldn’t work anyhow due to the fact its not been “trained” who’s who.

Please let me know how your new version goes. I am desperate to get this facial recognition finally working on my mirror.

@Binog

Thanks for the info. I’ll keep trying stuff out and see what happens.

@Binog

Did you ever get an answer back on this one? I am having the same problem. I see everything fine without autohide active, but if I activate autohide, I see it for a bit during page load and never again after. I get detected motion emails and photo uploads so the detection isn’t the problem. It just doesn’t get fed to the mirror module somehow. Maybe my Web-hook config is off?

It would be helpful to know if you fixed your issue and how you did it.
