Crash when generating arf_layout for a directed twitter network
I want to plot a twitter dataset(http://snap.stanford.edu/data/twitter_combined.txt.gz) with arf_layout, and the program crashed with:
Traceback (most recent call last):
File "plot.py", line 10, in <module>
vcmap=matplotlib.cm.gist_heat_r, output="twitter.png")
File "/usr/local/lib/python2.7/site-packages/graph_tool/draw/cairo_draw.py", line 926, in graph_draw
cr.translate(offset[0], offset[1])
cairo.Error: invalid matrix (not invertible)
I can't find out the reason, because the twitter network has too many edges... I've tried karate network and price network. Both work fine with arf_layout.
