我正在运行lasagne/nolearn，它使用theano。
安装和编译theano尤其困难。安装64位g++编译器后，会发生以下编译错误。
非常感谢您的帮助。谢谢!
使用以下命令行在编译过程中发生了问题:

最佳答案
我发现了问题所在，并希望发布解决方案。造成此特定问题的原因是，在您找到pythonxx.dll文件的同一目录中缺少文件libpythonxx.a(在我的情况下为python27.dll，因此我创建了libpython27.a文件)。
一位高尚的灵魂在http://rosinality.ncity.net/doku.php?id=python:installing_theano上发布了安装theano的所有必要步骤(韩语和英语)。要生成此类文件，请将pythonxx.dll文件复制到一个临时目录，然后在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，通常可以在C:\Windows\System3下找到此文件，但是如果您使用的是Anaconda，您会在下面找到它吗？
C:\Users\xxxxx\Anaconda\libs，xxxxx是您的用户。
