python opencv error

import cv2

capture = cv2.VideoCapture(0) capture.set(cv2.CAP_PROP_FRAME_WIDTH, 640) capture.set(cv2.CAP_PROP_FRAME_HEIGHT, 480)

while True: ret, frame = capture.read() cv2.imshow("VideoFrame", frame) if cv2.waitKey(10) > 0: break

capture.release() cv2.destroyAllWindows()

I'm working on a code to film a video using a laptop cam repeatedly C:\Users\dntjd\PycharmProjects\practice\venv\Scripts\python.exe C:/Users/dntjd/PycharmProjects/practice/practice1.py Traceback (most recent call last): File "C:/Users/dntjd/PycharmProjects/practice/practice1.py", line 9, in cv2.imshow("VideoFrame", frame) cv2.error: OpenCV(4.0.0) C:\projects\opencv-python\opencv\modules\highgui\src\window.cpp:350: error: (-215:Assertion failed) size.width>0 && size.height>0 in function 'cv::imshow'

Process finished with exit code 1

I see this errorㅜ I'm posting a question because there's no clear solution no matter how much I look for it.
