This is a common problem experienced by many. Solve it by adding the cv2 data path at the initialization stage.

Creating face_cascade and eye_cascade objects

This is your face detection and eye detection initialization

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

Change them to the following format

face_cascade=cv2.CascadeClassifier(cv2.data.haarcascades +"haarcascade_frontalface_default.xml")
eye_cascade=cv2.CascadeClassifier(cv2.data.haarcascades + "haarcascade_eye.xml")
