I have followed this guide to install Open CV on my Raspberry pi3, with noobs on it, for both python2 and python3, but still can't import cv2 in python, (and can't find it when running pip freeze as well).
What might be the problem? (suggestions, tests that will help me figure it out) I've tried import cv2 and got the following output: Traceback (most recent call last): File "stdin", line 1, in module ImportError: No module named 'cv2'
