ubuntu14 python2.7上安装scipy,numpy,matplotlib的方法

sudo apt-get install python-nose

sudo apt-get install python-scipy

sudo apt-get install python-numpy

sudo apt-get install python-matplotlib

python

import scipy

import numpy

import pylab

scipy.test()

numpy.test()

pylab.test()

后面三个包依赖nose,要先安装，否则在执行最后三个xxx.test()时会报如下错误：

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "/usr/lib/python2.7/dist-packages/numpy/testing/nosetester.py", line 351, in test

    self._show_system_info()

  File "/usr/lib/python2.7/dist-packages/numpy/testing/nosetester.py", line 204, in _show_system_info

    nose = import_nose()

  File "/usr/lib/python2.7/dist-packages/numpy/testing/nosetester.py", line 74, in import_nose

    raise ImportError(msg)
