Hello! I have a face recognition code:
import cv2
import numpy as np
from PIL import Image
import os

# Path for face image database
path = ‘dataset’

recognizer = cv2.face.LBPHFaceRecognizer_create()
detector = cv2.CascadeClassifier(“haarcascade_frontalface_default.xml”);

# function to get the images and label data
def getImagesAndLabels(path):

imagePaths =
faceSamples=
ids =

for imagePath in imagePaths:

PIL_img = Image.open(imagePath).convert('L') # convert it to grayscale
img_numpy = np.array(PIL_img,'uint8')

id = int(os.path.split(imagePath).split(“.”))
faces = detector.detectMultiScale(img_numpy)

for (x,y,w,h) in faces:
faceSamples.append(img_numpy)
ids.append(id)

return faceSamples,ids

print ("\n Training faces. It will take a few seconds. Wait …“)
faces,ids = getImagesAndLabels(path)
recognizer.train(faces, np.array(ids))

# Save the model into trainer/trainer.yml
recognizer.write('trainer/trainer.yml') # recognizer.save() worked on Mac, but not on Pi

# Print the numer of faces trained and end program
print(”\n {0} faces trained. Exiting Program".format(len(np.unique(ids))))
after running it, an error occurs:
line 9, in
recognizer = cv2.face.LBPHFaceRecognizer_create()
AttributeError: module ‘cv2’ has no attribute ‘face’
help solve this problem
P.S. Reinstalling the opencv-contrib-python package did not help.

Reinstalling the opencv-contrib-python package did not help.

Option 2 - Full package (contains both main modules and contrib/extra modules): pip install opencv-contrib-python

py.user.next

My steps: pip uninstall opencv-python then
pip install opencv-contrib-python

pip uninstall opencv-python
pip uninstall opencv-contrib-python

pip3 uninstall opencv-python
pip3 uninstall opencv-contrib-python

pip install opencv-contrib-python

pip3 install opencv-contrib-python

  
>>> import cv2
>>> cv2.face
<module 'cv2.face'>
>>>
