OpenCV 4.9.0 with CUDA Build - Python: "No Module Named 'cv2'"

Python
,
7

Final update… I got it to build and I’m able to use OpenCV in my Python project.

The last error message of: \Code\Python\opencv-test\venv\Scripts\python37.dll : fatal error LNK1107: invalid or corrupt file: cannot read at 0x300 was because my build script was pointing to Python37.dll but should have been Python37.lib.
I copied Python37.lib into my venv/Lib folder and voila!

Here’s the build script I used if anyone’s interested:

@echo off
setlocal

:: Clean build folder
if exist "C:\OpenCV_4.9.0\build" rmdir /s /q "C:\OpenCV_4.9.0\build"
