face_cascade = cv2.CascadeClassifier('./opencv/haarcascades/haarcascade_frontalface_default.xml')
eye_cascade = cv2.CascadeClassifier('./opencv/haarcascades/haarcascade_eye.xml')

faces = face_cascade.detectMultiScale(gray, 1.3, 5)
faces

firstly check-in your directory named as or similar to C:/Python/Lib/site-packages/cv2 XML files are present if they are, then instead of ./opencv/haarcascades/haarcascade_frontalface_default.xml use the same XML file name from your directory.

and if they are not present then firstly download that files in that directory. https://github.com/anaustinbeing/haar-cascade-files you can download it from here.
