original_image = cv2.cvtColor(img, cv2.COLOR_BGR2RGB) original_image = cv2.cvtColor(original_image, cv2.COLOR_BGR2RGB) code example

Example: error: (-215:Assertion failed) !_src.empty() in function 'cv::cvtColor'

This error happened because the image didn't load properly.
So you have problem with the previous line cv2.imread my suggestion is :

check if the images exist in the path you give

check the count variable if he have valid number
