在Windows上安装带Python的Dynet时出错

Question

我按照这里的教程：http://dynet.readthedocs.io/en/latest/python.html#windows-python-install 用于安装带GPU和Python的Dynet。在

我可以进入我运行cmake的阶段，一切似乎都很好。问题似乎在于构建Python项目。在

我运行：

cmake .. -DEIGEN3_INCLUDE_DIR=$PWD/../../eigen -DPYTHON=`which python` -DBACKEND=cuda -DCUDA_TOOLKIT_ROOT_DIR="C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v9.0" -G"Visual Studio 14 2015 Win64"

产生

^{pr2}$

一切似乎都很好。但是，当我尝试在Visual Studio上构建时，我在pydynet项目中遇到了37个错误，包括：

Severity    Code    Description Project File    Line    Suppression State
Error       command 'C:\\Users\\pie_a\\AppData\\Local\\Programs\\Common\\Microsoft\\Visual C++ for Python\\9.0\\VC\\Bin\\amd64\\cl.exe' failed with exit status 2   pydynet C:\Users\pie_a\Documents\coding\nlp\adc2181_h4\dynet-base\dynet\build\python\CUSTOMBUILD    1

我假设它目前不起作用，继续下一步失败，因为运行以下命令会出现错误：

我很乐意提供更多信息！可能安装了一些pip的问题。注意，当我第一次安装编译器时，我看到的是一个与c++不同的编译器版本。在

另外，这个变量的值是用Windowese而不是Unix格式的，这是个问题吗？我将其设置为系统环境变量。在

$ echo $VS90COMNTOOLS
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\

Answer 1

尝试将环境变量MSVC设置为1，然后重新生成。此变量告诉安装程序代码使用适用于Windows的设置。在
