The error shows the line where it's coming from

cv2.putText(img,str(id),(x,y+h),font,255)

The fourth parameter is expected to be a font object, but you've initialised it to a tuple here:

font= cv2.FONT_HERSHEY_COMPLEX_SMALL,5,1,0,4

I believe font should be only

font = cv2.FONT_HERSHEY_COMPLEX_SMALL

Look at the docs here.

Btw, you don't need semicolons in python.
