Facial Recognition Module - Step by Step Guide

[Irfan ali]

@MichiMauch Are You using Webcam ?

[naktah]

specify your user labels in the environment with

export FACE_USERS=Alice,Bob,Casey,Doug

im not sure what to do with this. do i have to write this in the terminal? because everytime i restart my pi, the facial recognition doesnt recognize my face

[sdetweil]

@naktah u need to put that in your logon profile

[naktah]

@sdetweil im not sure how to do that. can you show me how? im pretty much new to this stuff and this issue has been bothering me for days now.

[Sneek]

@naktah after writing the following command in the terminal:

python tools.train.py

you get some output with the users you have setup (remember the order). Assuming it gives you Alice,Bob,Casey,Doug, then you run this in the terminal:

export FACE_USERS=Alice,Bob,Casey,Doug

Error on “python capture.py”

pi@raspberrypi:~/MagicMirror/modules/MMM-Facial-Recognition-Tools $ python capture.py
Traceback (most recent call last):

@SdeGeata Got the same error, did you resolve it?

[sdetweil]

@aniketdongare07 @SdeGeata the newer version of python only provide 3 version info strings. So that code needs to drop the 4th parm from the parse request

(CV_MAJOR_VER, CV_MINOR_VER, mv1) = cv2.

[aniketdongare07]

@sdetweil I tried to do what you said and in turn I got the following error:```
Traceback (most recent call last):
File “capture.py”, line 18, in
import lib.capture as capture
File “/home/pi/MagicMirror/modules/MMM-Facial-Recognition-Tools/lib/capture.py”, line 21, in

(CV_MAJOR_VER, CV_MINOR_VER, mv1) = cv2
TypeError: ‘module’ object is not iterable

[sdetweil]

@aniketdongare07 you need the rest of the line cv2… I am on my phone, so cut/paste is a pain

(CV_MAJOR_VER, CV_MINOR_VER, mv1) = cv2.__version__.split(".")

@konradwalsh
I’m using Raspberry pi CSI camera.
How to do with it.
Please help me.

@sdetweil Hey, buddy… I’m not sure what it is you’re telling me to do here. I wrote what you sent into the terminal but it didn’t do anything. In fact, it’s treating the = sign as a syntax error… what am I doing wrong?

[sdetweil]

@ogelijah u have to edit the failing py script
and change the failing line

[OGElijah]

@sdetweil I get you! I was being an idiot and I went into the wrong script. But now I’ve reached the point where it says “no module named cv2”

[sdetweil]

@ogelijah no idea. that’s a python lib, which should have been installed from the prior setup steps

[OGElijah]

@sdetweil Ah, okay. I’ll keep on working on this. Cheers

[sdetweil]

@ogelijah because you replaced a line that used cv2, with another line that used cv2

@sdetweil
This fix worked! Thank you.

My error message:

python capture.py
Traceback (most recent call last):
File “capture.py”, line 18, in
import lib.capture as capture
File “/home/pi/MagicMirror/modules/MMM-Facial-Recognition-Tools/lib/capture.py”, line 21, in

(CV_MAJOR_VER, CV_MINOR_VER, mv1, mv2) = cv2.version.split(“.”)
ValueError: need more than 3 values to unpack

Steps to fix:

cd ~/MagicMirror/modules/MMM-Facial-Recognition-Tools/lib/
nano config.py

go to line 15 … I commented out the original line and added a line with ‘,mv2’ removed.

#(CV_MAJOR_VER, CV_MINOR_VER, mv1, mv2) = cv2.version.split(“.”)
(CV_MAJOR_VER, CV_MINOR_VER, mv1) = cv2.version.split(“.”)

I can’t get the .xml file no matter how hard I try… I keep running the train.py file and wait, but nothing happens
