face recognition opencv assertion failed

I am writing a face recognition code using opencv, and it returns an error at this line every time I run it.

This is the line of my code:

small_frame = cv2.resize(frame, None, fx=0.5, fy=0.5, interpolation=cv2.INTER_AREA)

The error it throws:

cv2.error: OpenCV(4.1.2) /io/opencv/modules/imgproc/src/resize.cpp:3720: error: (-215:Assertion failed) !ssize.empty() in function 'resize'

I think I could solve it if I can find this file named resize.cpp, but I don't know how to do it either.

That error means that frame is empty. There is no image!

if (frame is None):
    print('!!! EMPTY IMAGE')
    sys.exit(0)

small_frame = cv2.resize(frame, None, fx=0.5, fy=0.5, interpolation=cv2.INTER_AREA)
