如何安装opencvforpython3.4？

Answer 1

这是非常简单的方法：

我建议通过水蟒使用。

在水蟒中创造环境（推荐一种）： conda create -n deeplearning

然后，激活方式：activate deeplearning

现在，为Python3.x的python3.x安装opencv，如下所示：

• conda install -c https://conda.binstar.org/menpo opencv3

  This will simply install opencv3 and other related libraries as: spicy, numpy, scikit-learn and matplotlib in that environment.

检查Opencv是否安装为：

>>> import cv2
>>> cv2.__version__
'3.1.0'

Answer 2

关于这个有很多教程和问题。

This似乎回答了你的问题。编辑：复制如下：

1)  Download OpenCV from http://opencv.org/downloads.html and extract

2)From the extracted folder, copy the file from the extracted directory:   
opencv/build/python/2.7/(either x86 or x64, depending on your Anaconda 
version)/cv2.pyd to your Anaconda site-packages directory, e.g., 
C:\Anaconda\Lib\site-packages

3)To get ffmpeg within opencv to work, you'll have to add the directory 
that ffmpeg is located in to the path (e.g., opencv/sources/3rdparty
/ffmpeg). Then you'll have to find the dll in that folder (e.g., 
opencv_ffmpeg_64.dll) and copy or rename it to a filename that includes 
the opencv version you are installing, (e.g., opencv_ffmpeg249_64) for 
2.4.9.

{结束复制}

EDIT2：OpenCV不支持Python 3.x，除了opencv3.0版（仍处于测试阶段）。从下载站点下载3.0版本并尝试（感谢this question）。

A SO question with a possible tip, if the previous doesn't work.

最后，我将向您介绍如何安装它的read the docs tutorial。

祝你好运！
