UNSOLVED capture.py in MMM-Facial-Recognition-Tools error

[emrhssla]

https://forum.magicmirror.builders/topic/6345/facial-recognition-module-step-by-step-guide
Referring to the above link, I was following the guidelines. But while following the guide, an error occurred in the Python capture.py part.
I am trying to run capture.py but getting this Error. I am using a webcam…

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 12, in
from builtins import input
ImportError: No module named builtins

python3 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 
     from . import config
   File "/home/pi/MagicMirror/modules/MMM-Facial-Recognition-Tools/lib/config.py", line 15, in 
     (CV_MAJOR_VER, CV_MINOR_VER, mv1, mv2) = cv2.__version__.split(".")
ValueError: not enough values to unpack (expected 4, got 3)

Then im tring to sudo pip install future --upgrade,
I modified the code in config.py
from CV_MAJOR_VER, CV_MINOR_VER, mv1, mv2 = cv2.version.split(“.”)
to CV_MAJOR_VER, CV_MINOR_VER, type = cv2.version.split(“.”)

try: python3 capture.py // python capture.py

success!!

I’m still worried. Is there anything wrong with it later?
