opencv: Import cv2 raises error, file in boostrap and DLL load failed

• OpenCV = latest
• Operating System / Platform => Windows 64 Bit
• Compiler => Visual Studio 2017
• Python 3.7.7

Detailed description

Please help, I had no luck on the opencv forum. I was able to succesfully install opencv with CUDA 10.2, but for the framework I am running it with, I needed CUDA 10.0. I am experiencing errors when importing cv2.

Steps to reproduce

I built opencv with cmake, and experienced no errors but “CMake Warning at cmake/OpenCVGenSetupVars.cmake:54 (message):” in which I unchecked it and the error resolved. After successfully building in VS, these are the commands and errors that followed:

C:\>python
Python 3.7.7 (tags/v3.7.7:d7c567b08f, Mar 10 2020, 10:41:24) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python37\cv2\__init__.py", line 96, in <module>
    bootstrap()
  File "C:\Python37\cv2\__init__.py", line 86, in bootstrap
    import cv2
ImportError: DLL load failed: The specified module could not be found.
>>>

How can I resolve these or any idea what causes this? I made sure the correct path was in my path in systems variable (C:\opencv\build\install\x64\vc15\bin).
