在Windows 7上导入Theano时出现g ++错误

Question

根据theano安装指南,我正在尝试使用正确的g ++安装进行设置.我以前有theano使用python唯一的实现.我在python 3.4上使用他们的git repo中的最新版theano.我尝试过使用theano建议的TDM-GCC-64方法以及MinGW,两者都会产生完全相同的错误.(尽可能复制)

值得注意的是,在打印此错误之前,它会输出整个文件的代码,你可以在这里找到整个错误输出

我不确定接下来会尝试什么,我已经按照指示两次,对一些依赖项使用了几种不同的安装方法,并确保在每次尝试和重新启动之间清理系统路径.

这对我有用:

1. 转到您的用户文件夹:C:/ Users/[username]
2. 如果尚未存在,请创建.theanorc文件

3. 确保它包含以下行:

   [gcc]
   cxxflags = -D_hypot=hypot
