My machine is windows machine. I have Ubuntu hosted in virtual box. I used apt-get to install opencv-python. Now when I try to import cv2, I get an error message: Import Error: No module named cv2. I have python 2.7 and 3.5, but I have changed the interpreter from python 2.7 to 3.5 in my Pycharm IDE. I am on Ubuntu 16.04 LTS.
When I try to use pip to install opencv, I get an error message: Permission denied. How do I install opencv using python 3.5 64bit without running into these nasty errors?
