I have two separate projects, proj1 and proj2. Both use opencv with `import cv2`
- was created with a virtualenv called env and I pip installed opencv-python.
- displays "No suggestions" on cv2.imread and doesn't display any documentation
- proj1 can autocomplete and show Documentation if I `import cv2.cv2`
- was opened on pycharm and instructed to use proj1's env.
- autocompletes cv2.imread and displays Documentation in the side window.
I searched the web everywhere and was hinted the cv2.cv2 solution but this works on one and not the other.
I can provide the .idea xml's or some config files you need.
