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。
在终端修改和替换源的方法
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-numpysudo apt-get install Python-scipysudo apt-get install python-matplotlibsudo 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 npfrom scipy.stats import betafrom matplotlib.pyplot import hist, plot, showobs = beta.rvs(5, 5, size=2000) # 2000 observationshist(obs, bins=40, normed=True)grid = np.linspace(0.01, 0.99, 100)plot(grid, beta.pdf(grid, 5, 5), 'k-', linewidth=2)show()
MatPlotLib测试代码
from mpl_toolkits.mplot3d import axes3dimport matplotlib.pyplot as pltfrom matplotlib import cmfig = plt.figure()ax = fig.gca(projection='3d')X, Y, Z = axes3d.get_test_data(0.05)ax.plot_surface(X, Y, Z, rstride=8, cstride=8, alpha=0.3)cset = ax.contour(X, Y, Z, zdir='z', offset=-100, cmap=cm.coolwarm)cset = ax.contour(X, Y, Z, zdir='x', offset=-40, cmap=cm.coolwarm)cset = ax.contour(X, Y, Z, 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
提示如下错误:
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/locksudo 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,
