title: What is the different between opencv-python library and cv2 library?
body: <p>I am trying to use openCV. Normally, When I run command panel on desktop, I can see version of my openCV:</p>

  <p>But when I couldn't import to my project. Normally, I was adding opencv-python library from interpreter but I builded cv2 library which version is 4.4.0 to use gpu. So I haven't got a opencv-python library at site-packages but I have cv2 file in site-packages. Unfortunately I couldn't import it to my project. How can I use this opencv version or file which name is cv2.cp37-win_amd64.pyd?</p>
