虚拟环境中的Opencv3和Python 2.7 - AttributeError：'module'对象没...
本帖最后由 HelloWorld 于 2018-10-13 10:12 编辑我有一个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：
AttributeError: 'module' object has no attribute 'createLBPHFaceRecognizer'
在终端没有venv：
gkhan@Gkan ~/Masaüstü/face_recognizer $ python face_recognizer.py
Yol :./sinif/114.jpg.
114 Yuz Tanindi 12与终端的venv：
gkhan@Gkan ~/Masaüstü/face_recognizer $ workon cv
(cv)gkhan@Gkan ~/Masaüstü/face_recognizer $ python face_recognizer.py
Traceback (most recent call last):
File "face_recognizer.py", line 15, in <module>
recognizer = cv2.createLBPHFaceRecognizer()
AttributeError: 'module' object has no attribute 'createLBPHFaceRecognizer代码如下：
#!/usr/bin/python
# -*- coding: utf-8 -*-
import cv2, os
import numpy as np
from PIL import Image
# For Test
if 0==0:
cascadePath = "haarcascade_frontalface_default.xml"
faceCascade = cv2.CascadeClassifier(cascadePath)
recognizer = cv2.createLBPHFaceRecognizer()
...我在Linux Mint 64 Bit上使用python 2.7运行Opencv3

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”。
NAME
cv2.face
FILE
(built-in)
FUNCTIONS
createEigenFaceRecognizer(...)
createEigenFaceRecognizer([, num_components[, threshold]]) -> retval
createFisherFaceRecognizer(...)
createFisherFaceRecognizer([, num_components[, threshold]]) -> retval
createLBPHFaceRecognizer(...)
createLBPHFaceRecognizer([, radius[, neighbors[, grid_x[, grid_y[, threshold]]]]]) -> retval
