python - 运行 theano 时编译失败 - Windows 8.1 64 位与 Anaconda python 发行版

Question

我正在运行使用 theano 的 lasagne/nolearn。

安装和编译theano特别困难。安装64位g++编译器后出现如下编译错误。

非常感谢您的帮助。谢谢!

使用以下命令行编译时出现问题:

我发现了问题所在，并想发布解决方案。这个特殊问题是因为文件 libpythonxx.a 文件在找到 pythonxx.dll 文件的同一目录中丢失(在我的例子中是 python27.dll，因此我创建了 libpython27.a 文件。

一位高贵的灵魂在 http://rosinality.ncity.net/doku.php?id=python:installing_theano 发布了安装 theano 的所有必要步骤(韩语和英语)。要生成此类文件，请将 pythonxx.dll 文件复制到临时目录并在 Windows 控制台中键入以下命令:

gendef pythonXX.dll

dlltool --as-flags=--64 -m i386:x86-64 -k --output-lib libpythonXX.a --input-def pythonXX.def

然后将生成的 libpythonxx.a 文件粘贴到与 pythonxx.dll 文件相同的目录中。

在windows中，你通常会在C:\Windows\System3下找到这个文件，但如果你像我一样使用anaconda，你会在下面找到它吗？

C:\Users\xxxxx\Anaconda\libs，xxxxx 是您的用户。
