windows下执行pip install pycuda的时候报错：

    error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": https://visualstudio.microsoft.com/downloads/

解决办法：

1. 下载安装Visual Studio
   或者
2. 下载编译好的pycuda直接安装（Unofficial Windows Binaries for Python Extension Packages），地址：https://www.lfd.uci.edu/~gohlke/pythonlibs/
