運行theano時編譯失敗 - Windows 8.1的64位與蟒蛇python分佈

Question

我正在運行lasagne/nolearn，它使用theano。

安裝和編譯theano特別困難。安裝64位g ++編譯器後發生以下編譯錯誤。

非常感謝幫助。謝謝！編譯過程中發生

問題與下面的命令行：

Answer 1

我發現了什麼問題是，想發佈的解決方案。這個特殊的問題是由於文件libpythonxx.a文件在找到pythonxx.dll文件的同一目錄中丟失（在我的情況下是python27.dll，因此我創建了libpython27.a文件）。

高貴的靈魂要生成這樣的文件，請將pythonxx.dll文件複製到臨時目錄，然後在Windows控制檯中鍵入以下命令：

gendef pythonXX.dll

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

然後將生成的libpythonxx.a文件粘貼到與pythonxx.dll文件相同的目錄中。

在Windows中，您通常會在C：\ Windows \ System3下找到該文件，但如果您使用的是anaconda，那麼您會在下面找到它？

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

對於使用WinPython和MinGW，在這裏一些額外的信息，這些：

1）甚至懶得使用64位Windows時嘗試mingw32的包，馬上去mingw64。這將停止發生以上顯示的錯誤

2）對於WinPython，.theanorc或.theanorc.txt文件不能位於您的主目錄中，而必須位於WinPython/settings目錄中！

3）製作的東西通過使用Linux風格路徑分隔符，例如，對於g ++標誌，CXX = d更容易：

4）NVCC需要的/ dev /的mingw-W64/mingw64/bin中/克++ EXE。 Windows路徑已列入中的cl.exe文件，它可以在一般你下的東西被發現VS安裝像（VSPATH）/ VC/bin中
