Unable to import cv2 module (Python 3.6)

Try to do:

pip3 install opencv-python

It works for python 3.5

For python 3.6 The conda install opencv and conda install -c conda-forge opencv methods for OpenCV continue to be BROKEN for video/image reading and display.

Use pip install below instead:

python -m pip install opencv-python
