my code is given below for face recognizer

import numpy as np
import cv2

face_cascade = cv2.CascadeClassifier('/home/programmer/Desktop/project/cascades/data/cascades/data/haarcascade_fontalface_alt2.xml')

cap = cv2.VideoCapture(0)

while True:
    ret, frame = cap.read()
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
    faces = face_cascade.detectMultiScale(gray, scaleFactor=1.5, minNeighbors=5)
    for(x, y, w, h) in faces:
        print(x,y,w,h)

You have duplicated path? /cascades/data/cascades/data/ It could be like this /cascades/data/haarcascade_fontalface_alt2.xml. Even, if you not sure, why not put haarcascade_fontalface_alt2.xml in your currently folder and see what happen.
