在 Windows 上使用 Python 安装 Dynet 时出错

Question

我正在学习这里的教程：http://dynet.readthedocs.io/en/latest/python.html#windows-python-install 用于安装带有 GPU 和 Python 的 Dynet。

我可以进入运行 cmake 的步骤，一切似乎都很好。问题似乎在于构建 Python 项目。

我跑：

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

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

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

我认为此时它还没有工作，并且继续下一步失败，因为运行以下命令会出错：

我很乐意提供更多信息！问题的几个可能来源：我用 pip 安装了 Boost。我看到一条注释说 c++ 编译器需要与您安装 Boost 的编译器的版本相同，但是 Visual Studio 上的一条消息让我在第一次构建时安装了不同的 c++ 驱动程序。

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

$ 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 并重新构建。此变量告诉设置代码使用适用于 Windows 的设置。
