Solution 1:

You need to install cv2 before it will work. cv2 is really opencv but to install it you need to activate your virtual environment and then type: pip install opencv-python. On a discussion dated in July 2018 it was stated that opencv was not compatible with python 3.7 but did work with versions 3.5 and 3.65. It may be compatible now.

Solution 2:

I believe I have an answer to my own question.

I simply installed the 'Hydrogen' package via Atom --> Preferences --> Packages

Now I can start a virtual environment and control it all within the Atom application.

Problem solved :-)
