Python34安装NumPy

numpy 准确地说提供了一个在python中做科学计算的基础库，侠义地讲它重在数值计算，甚至可以说是用于多维数组处理的库；而 scipy 则是基于numpy，提供了一个在python中做科学计算的工具集，也就是说它是更上一个层次的库。
下面只介绍numpy的安装方法（scipy一样）

1、下载对应版本NumPy（我用的python3.4下载对应numpy-1.9.2+unoptimized-cp34-none-win32.whl）

http://sourceforge.net/projects/numpy/files/NumPy/

python3.4 Delbert默认版本为3.4，第二步不用执行。2.7的就得安装wheel

2、由于下载下来的包是wheel格式的，需要wheel支持。所以需要先通过cd命令切换到python安装路径下的Script文件夹，输入 pip install wheel 来安装wheel。

C:\Python34\Scripts>pip install wheel
You are using pip version 6.0.8, however version 7.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command. Collecting wheel
  Downloading wheel-0.24.0-py2.py3-none-any.whl (63kB)

Installing collected packages: wheel

Successfully installed wheel-0.24.0

3、 pip install 来进行安装

C:\Python34\Scripts>pip install C:\Python34\numpy-1.9.2+unoptimized-cp34-none-w in32.whl
You are using pip version 6.0.8, however version 7.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command. Processing c:\python34\numpy-1.9.2+unoptimized-cp34-none-win32.whl
Installing collected packages: numpy Successfully installed numpy-1.9.2

4、进入python运行环境（cmd）


C:\Python34\Scripts>C:\Python34\python.exe
Python 3.4.3 (v3.4.3:9b73f1c3e601, Feb 24 2015, 22:43:06) [MSC v.1600 32 bit (In
tel)] on win32

在python下导入numpy
>>>; from numpy import *

安装完成，可以测试了。
4*4的随机数组：

>>> random.rand(4,4)
