How to import cv correctly

Question

So, I am trying to run this code https://stackoverflow.com/a/12861798/13176726 but I am stuck with the ModuleNotFoundError: No module named 'cv'

I have tried all the recommendation and followed all the answers but still. I am using windows.

You will do import cv2, not import cv

when I run it now the rest of the code is messed and the error showing: `NameError: name 'cv' is not defined` – A_K Oct 29 '20 at 23:46
import cv2 as cv – DPM Oct 29 '20 at 23:48
@DPM, What is the point of `import cv2 as cv`? You will save 1 character? Hacky solutions almost always end up bad. I think it is best to have the right solution – smttsp Oct 29 '20 at 23:54
@A_K, you can replace all `cv`'s with `cv2`. That should resolve your issue – smttsp Oct 29 '20 at 23:54
@smttsp i tried replacing cv with cv2 but the error that came up is `AttributeError: module 'cv2.cv2' has no attribute 'LoadImage'` – A_K Oct 30 '20 at 00:00
`LoadImage` should be an ancient method. `cv2.imread(filename)` is the right way to load the image. – smttsp Oct 30 '20 at 00:01
Your project sounds like written in `opencv v1`. If you have `IplImage` etc in your code, I think it is best for you to refactor the code a lot. – smttsp Oct 30 '20 at 00:03
