blurred_box = cv2.blur(
cv2.error: OpenCV(4.7.0) /io/opencv/modules/imgproc/src/box_filter.dispatch.cpp:446: error: (-215:Assertion failed) !_src.empty() in function 'boxFilter'

In addition to the error, there is a problem that the position of the blur does not settle properly on the face if it is not a 4:3 ratio image. How can I solve this?
