1. 安裝setuptools
wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
2. 安裝networkx
pip install networkx（在root權限下安裝，否則報錯，但我在安裝時出現一些警告信息）
3. 安裝numpy和matplotlib（支持networkx繪圖）
sudo apt-get install python-numpy python-scipy python-matplotlib ipython ipython-notebook python-pandas python-sympy python-nose
4. 使用networkx
4.1新建graph.py (任意名字)
import networkx as nx import matplotlib.pyplot as plt def draw_graph(graph): # extract nodes from graph nodes = set([n1 for n1, n2 in graph] + [n2 for n1, n2 in graph]) # create networkx graph G=nx.Graph() # add nodes for node in nodes: G.add_node(node) # add edges for edge in graph: G.add_edge(edge[0], edge[1]) # draw graph pos = nx.shell_layout(G) nx.draw(G, pos) # show graph plt.show() # draw example graph = [(20, 21),(21, 22),(22, 23), (23, 24),(24, 25), (25, 20)] draw_graph(graph)
4.2 執行graph.py
sudo python graph.py
