Import cv2 illegal values, failing to import

Question

I'm using Python 3.9.0 with pip version 20.3.1

I have successfully installed numpy-1.19.4 opencv-python-4.4.0.46 using pip install opencv-python

However, when I run import cv2 i get a myriad of errors

ImportError: numpy.core.multiarray failed to import

I've reinstalled python / nympy & openCV

I've tried pip install -U numpy in order to fix `ImportError: numpy.core.multiarray failed to import

Installing previous version of numpy, 1.19.3 should fix this. python -m pip install numpy==1.19.3
