After the cv2 library is installed, the calling function is highlighted in yellow

 Problem Description:

 Here is a demonstration of other people's mistakes. I have already changed it and I don't want to change it back. The calling function of cv2 above is highlighted in yellow, and the return value of the running program is a string of garbled characters.

Problem Description: The process has ended with exit code -1073741819 (0xC0000005)

Reason for analysis: the cv2 module is not fully imported

Solution:

1. Find the interpreter

 Mine is carried out in a virtual environment, open all display

 

 Click on the fifth icon: show interpreter path

 

 This is my path: the fourth is what is added

 Click the + sign to find the cv2 in your own environment

 This is my path, and then add that data, the problem is solved

 

 After adding, click OK

 The following is my code, and the yellow highlighting will solve it

If you haven't corrected my method, I would like to recommend someone's method:

There is no code prompt problem in python importing cv2 package in Pycharm (solved, the most effective in the whole network)

Although I didn't change the way I used him, it gave me an idea
