MMM-Facial-Recognition-OCV3 error at tools.train.py

Do you tried what are in the docu?

Test your trained model
Make sure your training.xml from running train.py is in this directory
Specify your user labels in the environment with

export FACE_USERS=name1,name2,name3

Run python tools.facerecognition.py to test your trained model.

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.

@SdeGeata
It seems he can’t resize the image for some reason. Have you checked all your pictures that nothing is corrupt and have you checked that your python has access to the files as well?

@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.

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.

Do you working with a mac? Maybe you have some issues with the permissioning, have you tried (only for testing) to give all folders full access? i had some issue also if i used sudo for some stuff where i shoudn’t.

I am currently working on a new version of face recognition with another method and the new ocv 4 version. Current tests works much better than this old module. i only need to finish the module soon. i think this or next week i should have a first version which works.

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.

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.

Cool that it works. I’m nearly done with my new module now. Will inform you if you can try out. And the good thing. The classes config from your old module will be compatible.
