theano 安裝 Windows mingw

Question

我正在嘗試使用 mingw32 在 Windows 7 上安裝 theano。 在此過程中，我還必須安裝 scipy，但在嘗試這樣做時，我收到此錯誤消息：

有解決方法嗎？ 我嘗試通過http://www.lfd.uci.edu/~gohlke/pythonlibs/安裝 scipy，但我在嘗試使用 mingw32 運行時遇到 64 位兼容性錯誤。 我已經使用 mingw for scipy 從源代碼構建了 lapack 和 blas 庫。

Answer 1

在Windows 7 x64上，我建議使用Enthought的Canopy，如果你是學生，你可以免費獲得完整的包。

或者，WinPython。

雖然，對於其中任何一個，您必須遵循所有步驟，包括：

安裝Windows軟件開發工具包7.1版，或者您可以安裝隨附的最新Visual Studio，它附帶一個安裝Microsoft Visual C ++ Compiler for Python 2.7的選項

安裝TDM GCC

但一定要檢查

您可能想檢查一下是否錯過了任何步驟。

我之前遇到過Anaconda和Theano的問題。 所以我放棄了使用它。 然而，一位朋友也成功地使用了Theano和Theano。

確保在安裝之前正確安裝了環境和python設置。

干

where gcc
where gendef
where cl
where nvcc

在命令提示符上

另外，請務必繼續檢查

Answer 2

我能夠通過安裝mingw64而不是mingw32來解決這個問題。
