一、安装numpy
下载numpy源码并解压。
wget http://jaist.dl.sourceforge.NET/project/numpy/NumPy/1.9.0/numpy-1.9.0.zip
安装numpy。
[root]# unzip numpy-1.9.0.zip
[root]# cd numpy-1.9.0
[root]# python setup.py install
安装完毕后，重启 。
[root]# reboot
测试是否安装成功，如果能导入numpy库，表示安装成功。
[myhaspl@localhost~]$ python
Python2.7.5 (default,Jun 17 2014,18:11:42)
[GCC4.8.2 20140120 (Red Hat 4.8.2-16)] on linux2

>>>import numpy as np

二、安装Scipy在使用 pip install scikit-learn 时报错，是安装依赖包scipy出错。
经过stack overflow查询，需要先运行
yum install blas-devel lapack-devel
wget https://github.com/scipy/scipy/releases/download/v0.17.0/scipy-0.17.0.zip
同上一样安装（注意python版本的兼容性）
三、
# pip install scikit-learn
