Opencv, Tkinter, Python 3, import imutils error on Mac

Question

I have got a face recognition program working using python 2 and am attempting to develop a GUI interface to run it. I tried using tkinter under python 2 but unfortunately many of the widgets don't work or at least not very well, so I created a GUI with python 3, which looks reasonable. Unfortunately.

When I try to incorporate the Computer Vision program into the GUI it fails with the following:

 File "facePanel.py", line 24, in <module> import imutils File "/usr/local/lib/python3.7/site-packages/imutils/__init__.py", line 8, in <module> from.convenience import translate File "/usr/local/lib/python3.7/site-packages/imutils/convenience.py", line 6, in <module> import cv2 File "/usr/local/lib/python3.7/site-packages/cv2/__init__.py", line 89, in <module> bootstrap() File "/usr/local/lib/python3.7/site-packages/cv2/__init__.py", line 79, in bootstrap import cv2 ImportError: dlopen(/usr/local/lib/python3.7/site-packages/cv2/python-3.7/cv2.cpython-37m-darwin.so, 2): Library not loaded: /usr/local/opt/glog/lib/libglog.0.dylib Referenced from: /usr/local/Cellar/opencv/4.1.0_1/lib/libopencv_sfm.4.1.dylib Reason: image not found

So I tried installing imutils under python 3:

    $ sudo pip3 install imutils

Which tells me that the requirement is already satisfied:

Requirement already satisfied: imutils in /usr/local/lib/python3.7/site-packages (0.5.2)

I am new to OpenCV, Tkinter and Python so any pointers as to how to solve the issue would be greatly appreciated.

Thanks in advance

Problem fixed with the following:
