Process finished with exit code 134 (interrupted by signal 6: SIGABRT) in python OpenCV

Question

import numpy as np
import cv2

cap = cv2.VideoCapture(0)

while(True):
    # Capture frame-by-frame
    ret, frame = cap.read()

    # Our operations on the frame come here
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

    # Display the resulting frame
    cv2.imshow('frame',gray)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

# When everything done, release the capture
cap.release()
cv2.destroyAllWindows()

I'm using Python and OpenCV in Pycharm IDE. When I try to open the webcam using OpenCV, it gives the following error:

" Process finished with exit code 134 (interrupted by signal 6: SIGABRT) "

Is this happening because I'm running out of memory? What are the solutions for this?

I'm using PyCharm on MacBook Pro (OS: Mojave)

Thanks!

Answer 1

1. Open /Applications/PyCharm.app/Contents/info.plist,

2. Insert a new line:

   • Key: Privacy - Camera Usage
   • Type: String
   • Value: An application in PyCharm wants to use the camera.

3. Save it.

4. Reopen PyCharm.
5. Run your code.

Answer 2

I have opened an issue at Jetbrains because of this. But here is a workaround:

Run PyCharm / IntelliJ (whatever Jetbrains App) from an application which already has been approved for camera access. For example I use the Hyper Terminal to run the IDE and everything works.

Answer 3

通过在 vs code（visual studio code）中运行 python 脚本将执行程序而没有任何警告或错误。

Answer 4

Open /Applications/PyCharm.app/Contents/info.plist in any text editor. Add these two line before dict & plist tag:

<key>Privacy - Camera Usage</key>
<string>An application in PyCharm wants to use the camera.</string>
</dict>
</plist>
