OpenCV w/CUDA build seems successful, but "import cv2" fails

Thank you for your question. The *.pyd is in the appropriate location:
C:\Users<username>\anaconda3\envs\py38\Lib\site-packages

I realize that I made mistake in that portion of my post. I believe I did not activate the correct conda environment before trying to import. I’ve updated the post. notice that the output is:

ImportError: DLL load failed while importing cv2: The specified module could not be found.

That is distinct from trying to import a module that does not exist. in that case, the output is:

ModuleNotFoundError: No module named 'unicorn'
