运行包含import theano的Python脚本时，出现此错误：

它看起来像g++.exe: error: CreateProcess: No such file or directory是由缺less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 。 我该如何得到这个文件？
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，我改变了g ++编译器，即TDM-GCC MinGW编译器，以便编译为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: sorry, unimplemented: 64-bit mode not compiled in ）。
从这里 。
你关闭了命令窗口并打开了一个新窗口？ （通过标准的Windows对话窗口）对你的环境变量的改变将不适用于打开的命令窗口（尽管你可以在打开的命令窗口中分别手动设置变量）。
如果设置环境变量没有帮助，对链接问题的其他答案可能会有所帮助。
