AttributeError: module ‘cv2.cv2’ has no attribute ‘createLBPHFaceRecognizer’

在某一次做人脸识别的小demo的过程中遇到了这个问题
下面直接上产生问题的源代码

import cv2
import numpy as np
from PIL import Image
import os

#Path for image database
path='../dataset'

recognizer=cv2.face.LBPHFaceRecognizer_create()
detector=cv2.CascadeClassifier('/home/cillian/opencv/data/haarcascades/haarcascade_frontalface_default.xml')

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

    imagePaths=[os.path.join(path,f) for f in os.listdir(path)]
    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)[-1].split(".")[1])
        faces=detector.detectMultiScale(img_numpy)

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

    return faceSamples,ids

print("\n [INFO] 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.yml') # recognizer.save() worked on Mac, but not on Pi

# Print the numer of faces trained and end program
print("\n [INFO] {0} faces trained. Exiting Program".format(len(np.unique(ids))))

源代码没有什么问题，主要是有相关的依赖没有安装

在终端下输入:
pip install opencv-contrib-python
