Re: [igraph] Error message when plotting graph with python iGraph

[Rodrigo Matus Nicodemos]

Hi Jan,

I did install pycairo, specifically py2cairo. I used homebrew to install it, but I am not sure if it was installed properly with homebrew.

Thanks.

Rodrigo

Zitat von Rodrigo Matus Nicodemos <address@hidden>:

Hello,

I've installed python iGraph and its dependencies to try it out. I have
been going through the tutorial and I get an error message when I try to
plot the graph.

Here is the simple code I used from the tutorial:

from igraph import *

g = Graph([(0,1),(0,2),(2,3),(3,4),(4,2),(2,5),(5,0),(6,3),(5,6)])

g.vs["name"] = ["Alice", "Bob", "Claire", "Dennis", "Esther", "Frank",

"George"]

g.vs["age"] = [25, 31, 18, 47, 22, 23, 50]

g.vs["gender"] = ["f", "m", "f", "m", "f", "m", "m"]

g.es["is_formal"] = [False, False, True, True, True, False, True,

False, False]

layout = g.layout("kk")

When I do the next command:

plot(g, layout = layout)

I get this error message:


Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "build/bdist.macosx-10.5-x86_64/egg/igraph/drawing/__init__.py",

  File "build/bdist.macosx-10.5-x86_64/egg/igraph/drawing/utils.py", line

TypeError: plotting not available


I am not sure why I am getting this? I would appreciate any advise.


Thanks.
