1.如果需要设置代理才能上网，那么先设置代理。
摘自：http://www.cnblogs.com/foonsun/p/5781767.html
ubuntu 全局代理，特别适合虚拟机nat，公司代理上网，强烈推荐
建立/etc/apt/apt.conf文件
其中写入代理，格式如下：
Acquire::http::proxy "http://192.168.2.200:808/"; Acquire::ftp::proxy "ftp://192.168.2.200:808/"; Acquire::https::proxy "https://192.168.2.200:808/";

2.更换源
可以通过图形界面去更换。
打开终端，输入命令：
sudo gedit /etc/apt/sources.list
更换完源之后，然后更新：
sudo apt-get update
3.安装numpy+scipy+matlotlib+scikit-learn
由于包之间有依赖关系，建议从上往下的顺序安装
sudo apt-get install python-numpy sudo apt-get install Python-scipy sudo apt-get install python-matplotlib sudo apt-get install python-sklearn
Numpy测试代码
from numpy import * print random.rand(4,4)
SciPy测试代码
import numpy as np from scipy.stats import beta from matplotlib.pyplot import hist,plot,show obs = beta.rvs(5,5,size=2000) # 2000 observations hist(obs,bins=40,normed=True) grid = np.linspace(0.01,0.99,100) plot(grid,beta.pdf(grid,5),'k-',linewidth=2) show()
MatPlotLib测试代码
from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt
from matplotlib import cm
fig = plt.figure()
ax = fig.gca(projection='3d')
X,Y,Z = axes3d.get_test_data(0.05)
ax.plot_surface(X,Z,rstride=8,cstride=8,alpha=0.3)
cset = ax.contour(X,zdir='z',offset=-100,cmap=cm.coolwarm)
cset = ax.contour(X,zdir='x',offset=-40,zdir='y',offset=40,cmap=cm.coolwarm)
ax.set_xlabel('X')
ax.set_xlim(-40,40)
ax.set_ylabel('Y')
ax.set_ylim(-40,40)
ax.set_zlabel('Z')
ax.set_zlim(-100,100)
plt.show()

今天想安装Python的pandas包，于是执行：
sudo apt-get install python-pandas
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/),is another process using it?
执行如下命令：
sudo rm /var/cache/apt/archives/lock sudo rm /var/lib/dpkg/lock
继续安装pandas
sudo apt-get install python-pandas
还是报错，如下：
E: dpkg was interrupted,you must manually run 'sudo dpkg --configure -a' to correct the problem.
解决方案，执行如下命令：
sudo dpkg --configure -a
执行上面的命令之后继续执行
sudo apt-get update
之后再继续运行安装python-pandas的命令，
