我在嘗試安裝Theano，這是我的情況。在Windows上安裝Thenth with Enthought Canopy
該系統是Windows 10（64位），CUDA 7.5與Visual Studio 2013一起安裝。Python發行版是Enthought Canopy（2.7.10,32位），帶有pip，numpy（1.9.2-3）和scipy（0.17.0-2）。安裝如下， 1.用PIP安裝Theano（0.7） 2.使用enpkg工具安裝mingw（4.8.1-2）和libpython（1.2）; 3.將新創建的libpython27.a複製到$ {PYTHONHOME}/Libs; 4.編輯和保存.theanorc.txt在c：\用戶\ $ {} MYNAME作爲

當我嘗試導入theano，我得到以下警告和錯誤：

我想知道是否是導致問題的32位Python與64位系統。
關於編譯/鏈接錯誤，是的，'-m32'告訴'nvcc'生成一個32位可執行文件。 CUDA 7.5中沒有32位版本的'cublas.lib'。實際上在[CUDA 7.0發佈說明]（http://developer.download.nvidia.com/compute/cuda/7_0/Prod/doc/CUDA_Toolkit_Release_Notes.pdf）中給出了32位cublas移除的通知「以下內容CUDA 驅動程序或CUDA工具包不再支持以下功能：‣32位版本的CUDA Toolkit科學庫，包括cuBLAS， cuSPARSE，cuFFT，cuRAND和NPP「。警告... gpu不可用是一個單獨的問題 –
@RobertCrovella謝謝，我切換到64位Python，它的工作 – chouzhupk
