32位的Windows，叫Win32-i386。i386也可叫做i686或者x86。 通常所说的64位的Windows，叫Win32-x86_64，x86_64也可叫做AMD64或者x64。虽然名字里有AMD，但是Intel的64位CPU也是这个指令集。 简单来讲： Win32 -> 指的就是Windows系统； 64 bit- > 指的是Windows是64位的； AMD64 -> 指的就是 CPU是x64的

如何确定安装win32的还是amd64，非常简单！ 我们直接通过platform看我们安装的python是什么版本，32bit就是win32了。而且自己在dos输入python的一开始的命令提示也显示了

0.12.4 - package version, they may be using semantic versioning cp27 - this package is for CPython. IronPython, Jython, or PyPy will probably be unhappy. CPython version 2.7. none - no feature of this package depends on the python Application Binary Interface, or ABI win_amd64 - this has been compiled for 64-bit Windows. That means that it probably has some code written in C/C++ .whl - that means this is a wheel distribution. Which is handy, because it means if you’re running CPython 2.7 64-bit on Windows, and assuming you have pip installed, all you have to do to get this package is run: py -2.7 -m pip install –use-wheel gensim (assuming that it’s available on pypi, of course). You may need to py -2.7 -m pip install wheel first. But other than that, that should be all it takes.

在gensim-0.12.4-cp27-none-win_amd64.whl中你可以将它分开：

0.12.4 – 包版本,他们可能正在使用semantic versioning cp27 – 此软件包适用于CPython. IronPython,Jython或PyPy可能会不高兴. none – 此软件包的功能取决于python Application Binary Interface, or ABI win_amd64 – 这是为64位Windows编译的.这意味着它可能有一些用C/C++编写的代码 .whl – 这意味着这是一个车轮分配.这很方便,因为这意味着如果你在Windows上运行CPython 2.7 64位,并假设你已经安装了pip,那么你需要做的就是运行这个软件包：py -2.7 -m pip install –use- wheel gensim(假设它在pypi上可用,当然).你可能需要先py -2.7 -m pip安装轮.但除此之外,应该只需要它.
