How to debug C++ code in a python program using VS2017?

edit

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/visu...) Now instead of release mode I install cv2 in debug mode : I copy build\opencv\lib\python3\Debug\cv2.cp36-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

stack trace is : python36_d.dll!PyUnicode_InternInPlace(_object * * p) Line 15272 C python36_d.dll!PyUnicode_InternFromString(const char * cp) Line 15307 C python36_d.dll!PyImport_Import(_object * module_name) Line 1711 C python36_d.dll!PyImport_ImportModule(const char * name) Line 1257 C cv2.cp36-win_amd64.pyd!_import_array() Line 1466 C++

my program is :

import numpy as np 
import cv2 as cv # <-- EXception  is here
img = cv.imread("g:/lib/opencv/samples/data/baboon.jpg")
