Hi,

Please open an issue in the website with this example, and I'll take a look at it when time permits.

Best, Tiago

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
