python - 属性错误: module 'cv2' has no attribute 'face' (OpenCV and Python)

Question

我已经尝试了很多方法，例如重新安装 CV2，但此错误不会消失。

这是代码:

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

# Path for face image database
path = 'C:\\Users\\lordg_000\\Desktop\\trainer'

recognizer = cv2.face.LBPHFaceRecognizer_create()
detector = cv2.CascadeClassifier("haarcascade_frontalface_default.xml");'

Answer 1

未安装扩展模块 Opencv_contrib。

解决方案:

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