I recommend installing the Anaconda distribution of Python. It contains more packages than you can dream of, including numpy of course: http://continuum.io/downloads
我建议安装Python的Anaconda分布。它包含的包比你想象的要多，当然包括numpy: http://continuum.io/downloads
The installation is as straightforward as installing the usual Python, no matter what OS you are on.
安装过程与安装常规的Python一样简单，无论您使用什么操作系统。

A good solution is to download the wheel file which match your Python version here:unofficial python binaries
一个好的解决方案是下载与您的Python版本匹配的wheel文件:非官方的Python二进制文件
And then go to the folder where the .whl file is present using the command prompt and unpack the wheel file xxxxx.whl with:
然后使用命令提示符进入.whl文件所在的文件夹，解压缩这个轮文件xxxxx。whl:
>python -m pip install xxxxx.whl
This will install the library in the Lib\site-packages folder, you can check it afterwards.
这将在Lib\site-packages文件夹中安装库，之后您可以查看它。
