python - Pycharm-运行打开的CV代码直接进入 “Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)”

Question

我正在尝试运行open-cv代码以使用python脚本访问我的网络摄像头。但是，当我尝试运行它时，每次尝试运行它时，都会收到“进程以退出代码139完成(信号11:SIGSEGV中断)”。我的代码没有错误，我还查看了其他文章来添加环境变量:PYTHONUNBUFFERED=1;PYDEVD_USE_FRAME_EVAL=NO;PYTHONMALLOC=debug我的代码是:

import cv2

# define a video capture object 
vid = cv2.VideoCapture(0)
while (True):
    # Capture the video frame
    # by frame
    ret, frame = vid.read()

    # display the resulting frame
    cv2.imshow('frame', frame)

    # the 'q button is set as the
    # quitting button
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

    # after the loop realse the cap object
    vid.release()
    # destroy all windows
    cv2.destroyAllWindows() 

Answer 1

最后两行必须在while循环之外:

import cv2

# define a video capture object 
vid = cv2.VideoCapture(0)
while (True):
    # Capture the video frame
    # by frame
    ret, frame = vid.read()

    # display the resulting frame
    cv2.imshow('frame', frame)

    # the 'q button is set as the
    # quitting button
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

# after the loop realse the cap object
vid.release()
# destroy all windows
cv2.destroyAllWindows()
