windows - 在 Windows 上使用 Theano : missing lazylinker_ext. pyd

Question

当运行包含 import theano 的 Python 脚本时，出现此错误:

===============================
00001   #include <Python.h>
00002   #include "structmember.h"
00003   #include <sys/time.h>
00004   
00005   // Old Python compatibility from here:
00006   // http://www.python.org/dev/peps/pep-0353/
[...]
01077       return RETVAL;
01078   }
01079   
01080   
Problem occurred during compilation with the command line below:

看起来像 g++.exe: error: CreateProcess: No such file or directory 是因为缺少文件 C:\Users\Francky\AppData\Local\Theano\compiledir_Windows-7-6.1.7601-SP1-Intel64_Family_6_Model_58_Stepping_9_GenuineIntel-2.7.10-64\lazylinker_ext\lazylinker_ext.pyd。我应该如何获取此文件？

我已经在 Anaconda Python 2.7.10 X64 中安装了 Theano，如下所示:

conda install mingw libpython
pip install theano

然后我更改了 g++ 编译器即 TDM-GCC MinGW Compiler以便它编译为 x64(否则我得到 C:\Users\Francky\AppData\Local\Theano\compiledir_Windows-7-6.1.7601-SP1-Intel64_Family_6_Model_58_Stepping_9_GenuineIntel-2.7.10-64\lazylinker_ext\mod.cpp: 1:抱歉，未实现:64 位模式未在 中编译)。

您是否关闭了命令窗口并打开了一个新窗口？对环境变量的更改(通过标准 Windows 对话窗口)将不适用于打开的命令窗口(尽管您可以在打开的命令窗口中单独手动设置变量)。

如果设置环境变量没有帮助，则对 linked question 的其他答案可能有帮助。
