虚拟环境中的Opencv3和Python 2.7 - AttributeError：'module'对象没...

HelloWorld

   我有一个opencv 3的python函数。它在没有虚拟环境的情况下工作。我还在venv上安装了opencv：pyimagesearch。我试图在venv上运行该python函数，然后它给出一个错误：

1. AttributeError: 'module' object has no attribute 'createLBPHFaceRecognizer'

复制代码

在终端没有venv：

1. gkhan@Gkan ~/Masaüstü/face_recognizer $ python face_recognizer.py
   
2. Yol :./sinif/114.jpg.
   
3. 114 Yuz Tanindi 12

复制代码

与终端的venv：

1. gkhan@Gkan ~/Masaüstü/face_recognizer $ workon cv
   
2. (cv)gkhan@Gkan ~/Masaüstü/face_recognizer $ python face_recognizer.py
   
3. Traceback (most recent call last):
   
4.   File "face_recognizer.py", line 15, in <module>
   
5.     recognizer = cv2.createLBPHFaceRecognizer()
   
6. AttributeError: 'module' object has no attribute 'createLBPHFaceRecognizer

复制代码

代码如下：

1. #!/usr/bin/python
   
2. # -*- coding: utf-8 -*-
   
3. 
   
4. import cv2, os
   
5. import numpy as np
   
6. from PIL import Image
   
7. 
   
8. # For Test
   
9. if 0==0:
   
10. 
    
11.     cascadePath = "haarcascade_frontalface_default.xml"
    
12.     faceCascade = cv2.CascadeClassifier(cascadePath)
    
13. 
    
14.     recognizer = cv2.createLBPHFaceRecognizer()
    
15. ...

我在Linux Mint 64 Bit上使用python 2.7运行Opencv3

stamina

从OpenCV 3开始，您必须获取并构建opencv_contrib存储库。然后你可以使用子模块“face”。

1. NAME
   
2.     cv2.face
   
3. 
   
4. FILE
   
5.     (built-in)
   
6. 
   
7. FUNCTIONS
   
8.     createEigenFaceRecognizer(...)
   
9.         createEigenFaceRecognizer([, num_components[, threshold]]) -> retval
   
10. 
    
11.     createFisherFaceRecognizer(...)
    
12.         createFisherFaceRecognizer([, num_components[, threshold]]) -> retval
    
13. 
    
14.     createLBPHFaceRecognizer(...)
    
15.         createLBPHFaceRecognizer([, radius[, neighbors[, grid_x[, grid_y[, threshold]]]]]) -> retval
