Lately I've been drawing graphs using the sfdp layout on graphviz_draw.
About 2 weeks ago before I installed some Python updates (not sure which
exactly), I had no problem drawing trees using this method.
When I run it I get the Spyder error "It seems the kernel died unexpectedly.
Use 'Restart kernel' to continue using this console." so something seems to
be crashing. I'm using Python 3.4.3. with graph-tool version 2.2.44. Any
ideas what might be happening?
