I am trying to install OpenCV 4.5.5 with CUDA support. I installed the source from their GitHub and the additional OpenCV contrib and built it with CMAKE. I checked BUILD_opencv_python3 when it was done configuring and generating it showed that it had detected python3 and had installed cv2 in site-packages.

But cv2 isn't in the site-packages.

So it doesn't load in python. But it does give an interesting error

What should I do?

I already tried doing a fresh build with CMAKE but it didn't work.

After building OpenCV it generates a PYD file in the lib folder. I don't know if that is helpful or not.

Thanks

You must have missed a step in the process.

• "Configure" step in cmake-gui, investigates the environment (various paths, e.g. where python wants packages to go) and prepares information for the build
• "Generate" step in cmake-gui, generates the actual build files (VS Solution)
• open the .sln in Visual Studio
• build the ALL_BUILD target
• build the INSTALL target, and this installs the files, also the python package
