Hello,
After updating graph_tool from version 2.33 to 2.35, I cannot make plots
with graphviz_draw() anymore. Here is a minimal example to reproduce the
error:
#################################
import graph_tool.all as gt
g = gt.Graph()
v0 = g.add_vertex()
v1 = g.add_vertex()
e01 = g.add_edge(v0,v1)
g_dict = {'layout':'neato'}
gt.graphviz_draw(g, gprops=g_dict)
#################################
The error message is:
#################################
Error: Layout type: "n" not recognized. Use one of: circo dot fdp neato
nop nop1 nop2 osage patchwork sfdp twopi
Error: Layout was not done
Segmentation fault
#################################
I suspect that somewhere the string 'neato' is converted to a single
character 'n'. In my real code, I also get several warning messages
quoting only the first character of miscellaneous strings.
I have python3-graph-tool installed on my computer which runs on Linux
Mint 19.2 Tina (based on Ubuntu 18.04 LTS, bionic). My graphviz version
is 2.40.1.
Can anyone reproduce this?
Best regards
Rolf
