Python 如何让Theano在Mac Lion上运行？

我需要让Theano为一个学校项目在我的Mac电脑上操作。我从（表的第一行）下载了源代码，并将未修改的文件放入我学校项目的保留库中。我不知道这是否足够，所以我还使用了

pip安装Theano

。自从我得到这个后，一切似乎都很好：

You are using pip version 6.1.1, however version 7.0.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Requirement already satisfied (use --upgrade to upgrade): Theano in ./anaconda/lib/python2.7/site-packages/Theano-0.7.0-py2.7.egg
Requirement already satisfied (use --upgrade to upgrade): numpy>=1.6.2 in ./anaconda/lib/python2.7/site-packages (from Theano)
Requirement already satisfied (use --upgrade to upgrade): scipy>=0.11 in ./anaconda/lib/python2.7/site-packages (from Theano)

如你所见，我用的是蟒蛇

但是，当我在python控制台中运行测试时，会收到以下消息：

>>> import theano
WARNING (theano.configdefaults): g++ not detected ! Theano will be unable to execute optimized C-implementations (for both CPU and GPU) and will default to Python implementations. Performance will be severely degraded. To remove this warning, set Theano flags cxx to an empty string.

有什么问题吗？Theano及其编译器是否安装良好？

我尝试了第一个示例，得到了相同的结果，没有任何错误。但我想知道如果我使用更复杂的函数和类，是否会有任何bug

您可能会选择Xcode命令行工具。另外，我会用自制软件安装一个合适的gcc工具链。然后使用pip（pip安装PyCUDA）安装PyCUDA，如果需要。此页面有一个很好的指南：如果您没有修复它，以下是安装说明：。它告诉你如何按照上面的评论安装编译后的软件。@fredrikhl谢谢你的链接。这是我对你建议的后续行动。有什么想法吗？
