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the second was an outdated PIP that wasn’t getting updated without SUDO that was giving me the error on Training.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 It was an outdated PIP that wasn’t getting updated without SUDO.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

@SdeGeata

I have gone ahead and started the process over again, just in case i missed something. I uninstalled everything and did a fresh install. It won’t even capture anymore, never-mind training with the images i already have.

I just want to get this thing going.

Hello Jimmy95!

Thank you for your reply. I forgot to mark this as solved. I ended up finding a work-around by changing the URL in the vdirsyncer config file from a specific URL to “from b”. It downloads and syncs all my calendars and notes - more than i need in fact; then I just add the URL for each calendar i want to see to the module instead.

Seems to be working well.

Thank you for your help though, and I will take a look at that link you provided to see if I can clean up and streamline the operations on my end anyhow.

@nischi

Yeah, all the photos load fine in preview app and they were all found, formatted and placed in the folder by the previous step. I don’t know why it is having a problem.

@nischi

Hello Nischi;

Only got as far as “python tools.train.py”. That is what generates the error and it doesn’t generate the XML file that it should, so I can’t verify my training.

Everything up until then is fine, and there are two named folders in the specified folder (training_data/) with pics of myself and my girlfriend. These photos were already processed by the previous function; “python tools.capture.py”. I don’t know why its bugging.

I have followed all the directives here, but pull two errors upon trying to train:

Can you help???

@SdeGeata Anyone got an answer to this one? I’m still stuck on this.

Bump! Same error message.

Re: Sync private iCloud calendar with MagicMirror

I can’t figure out how to add multiples to the array. I add one after another in the config to generate the local files and sync, but it only syncs the most recent one. I assume I need to have each one in the array? How is this done?
