本文介绍了在使用opencv-2.4.2安装pyopencv 2.1.0时遇到错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
当我用opencv-2.4.2安装pyopencv 2.1.0时遇到了一些错误，我的python版本是2.7.3，我的操作系统是OS X Mountain Lion，
I met some errors when I install pyopencv 2.1.0 with opencv-2.4.2, my python version is 2.7.3 and my os is OS X Mountain Lion,
并且下面的过程信息中，我发现一些错误表明重新定义了"Mat"类，但是我不知道如何解决它，请问有什么朋友可以帮助我吗?谢谢！
and the process information is below, I found some errors showed that the class 'Mat' is redefined, but I don't know how to fix it, does any friends could help me? thank!

推荐答案
根据pyopencv的第47期，似乎与OpenCV 2.3.1或更高版本不兼容.
According to Issue 47 of pyopencv, OpenCV 2.3.1 or later seems not compatible with it.
http://code.google.com/p/pyopencv/issues/detail?id = 47
考虑尝试使用cv2.so而不是pyopencv.
Consider trying cv2.so instead of pyopencv.
