centos 安装scikitlearn

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

Type"help", "copyright", "credits" or"license" for more information.

>>>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
