Error Message: 'cv2' has no attribute 'face'!

Python

i am trying to do something like this :

=====================================================
import os
import cv2
from PIL import Image pip install pillow
import numpy as np # pip install numpy

def train_classifier(data_dir):
path = [os.path.join(data_dir, f) for f in os.listdir(data_dir)]

faces = []
ids = []

for image in path:
    img = Image.open(image).convert('L')
    imageNp = np.array(img, 'uint8')
    id = int(os.path.split(image)[1].split(".")[1])
    
    faces.append(imageNp)
    ids.append(id)
    
ids = np.array(ids)

# Train and save classifier
clf = cv2.face.LBPHFaceRecognizer_create()
clf.train(faces,ids)
clf.write("classifier.xml")

train_classifier(“data”)

=====================================================
But there is error message coming is like this:

AttributeError Traceback (most recent call last)
Cell In[52], line 26
24 clf.train(faces,ids)
25 clf.write(“classifier.xml”)
—> 26 train_classifier(“data”)

Cell In[52], line 23, in train_classifier(data_dir)
20 ids = np.array(ids)
22 # Train and save classifier
—> 23 clf = cv2.face.LBPHFaceRecognizer_create()
24 clf.train(faces,ids)
25 clf.write(“classifier.xml”)

AttributeError: module ‘cv2’ has no attribute ‘face’

=====================================================
I have opencv version of 4.9.0
and I have tried uninstalling and then again installing opencv but nothing worked for me!

what should I do now?
