如何为Python 3.4安装OpenCV？

Question

我通过Anaconda发行版使用Python 3.4.他们似乎没有OpenCV的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

有很多关于此的教程和问题（关于SO）。

这似乎回答了你的问题。编辑：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.

{复制结束}

EDIT2：OpenCV 不支持 Python 3.x，除了 OpenCV 3.0 版本（仍处于实验阶段，处于测试阶段）。从下载网站下载3.0版本并尝试一下。（感谢这个问题）。

如果前一个不起作用，那么这个问题可能会有提示。

最后，我将引导您阅读有关如何安装它的文档教程。

祝你好运！
