Thanks, Tiago. I do have gtk3 installed. What I did was install XQuartz instead, and it helped fix this particular issue-- allowing me to run that line (from graph_tool.all import *) without error.

However, this error appeared

gi._glib.GError: Couldn't recognize the image file format for file '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/graph_tool/draw/graph-tool-logo.svg'
Exception AttributeError: "'GraphWindow' object has no attribute 'graph'" in <bound method GraphWindow.__del__ of <GraphWindow object at 0x13348b690 (graph_tool+draw+gtk_draw+GraphWindow at 0x7fb15c82a320)>> ignored

when I ran this:

from graph_tool.all import *

g1 = Graph()
v1 = g1.add_vertex()
v2 = g1.add_vertex()
e = g1.add_edge(v1,v2)

graph_draw(g1, vertex_text = g1.vertex_index, vertex_font_size = 18)

I couldn't find any other solutions online.

Thanks again.

Best,
E

These are just warnings, right? The module actually imports
successfully?

This is probably just because you don't have GTK+ 3 installed, which is
needed for interactive visualization. Just do:

port install gtk3

and everything should work.

Best,
Tiago
