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）
本机环境：win7, 64位 + python3.4
1、下载对应版本NumPy（我用的python3.4下载对应numpy-1.9.2+unoptimized-cp34-none-win amd64.whl）
http://www.lfd.uci.edu/~gohlke/pythonlibs/#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

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)
array([[ 0.90056883, 0.10542202, 0.02104658, 0.45606525],
[ 0.37256702, 0.38938058, 0.81695404, 0.3021916 ],
[ 0.02081778, 0.65920287, 0.18204678, 0.70915739],
[ 0.74607969, 0.9682355 , 0.49196832, 0.74588514]])
