Question

我通过Anaconda发行版使用Python 3.4。他们似乎没有为OpenCV提供Python 3.4绑定。我尝试从源头使用Cmake，但无济于事。有人可以帮我安装OpenCV for Python 3.4.x吗？

Answer 1

conda install -c menpo opencv3

诀窍。但是你必须安装anaconda。

Answer 2

关于此，有许多教程和问题（关于SO）。

This似乎回答了你的问题。修改：转载如下：

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.

EDIT2 ：OpenCV不支持Python 3.x，但OpenCV 3.0版除外（仍为实验版，测试版）。从下载站点下载3.0版本并试试。（感谢this question）。

Answer 3

这是非常简单的方法：

我建议通过anaconda使用。

在anaconda中创建环境（推荐一个）： conda create -n deeplearning

然后通过以下方式激活：activate deeplearning

现在，为Anaconda3的python3.x安装opencv：

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

这将简单地在该环境中安装opencv3和其他相关库，例如：辣，numpy，scikit-learn和matplotlib。

检查Opencv是否按以下方式安装：

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