I installed cv2 in release mode and everything is fine. Now I want to debug my python and C++ code (https://docs.microsoft.com/en-us/visualstudio/python/debugging-mixed-mode-c-cpp-python-in-visual-studio?view=vs-2017)
Now instead of release mode I install cv2 in debug mode : I copy build\opencv\lib\python3\Debug\cv2.cp37-win_amd64.pyd in
I have got eror :
Unhandled exception at 0x0000000065CC9E02 (python36_d.dll) in python.exe: 0xC0000005: Access violation reading location 0x0000000000000025. occurred

error is thrown by Python\Lib\site-packages\cv2__init__.py my program is :
import sys
if hasattr(sys, 'OpenCV_LOADER'):
print(sys.path)
raise ImportError('ERROR: recursion is detected during loading of "cv2" binary extensions. Check OpenCV installation.')
sys.OpenCV_LOADER = True
What is problem with my install in debug?
