Draw graph in NetworkX

Question

I'm trying to draw any graph in NetworkX, but get nothing, not even errors:

import networkx as nx import matplotlib.pyplot as plt g1=nx.petersen_graph() nx.draw(g1) 

Answer 1

Add to the end:

plt.show() 

---

import networkx as nx import matplotlib.pyplot as plt g1 = nx.petersen_graph() nx.draw(g1) plt.show() 

When run from an interactive shell where plt.ion() has been called, the plt.show() is not needed. This is probably why it is omitted in a lot of examples.

If you run these commands from a script (where plt.ion() has not been called), the plt.show() is needed. plt.ion() is okay for interactive sessions, but is not recommended for scripts.

Answer 2

in ipython notebook, just type in magic

%matplotlib inline 

or

%matplotlib notebook
