Looks like you can go around the error by just removing the flags field. Still seems to work.
UPDATE with opencv v3 (cv2 is still the module name, which makes it confusing), you can replace it with flags = cv2.CASCADE_SCALE_IMAGE (Solution at http://stackoverflow.com/questions/36242860/attribute-error-while-using-opencv-for-face-recognition)
@shantnu : Why do we need that field?
