Drawing OverlapBlockState()

graph-tool
1

Hi Prof. Peixoto,

gt version: 2.92
os: ubuntu 22
python: 3.9

the documentation clearly describes how to draw node marginals for BlockState() and NestedBlockState().
But is there any way we can draw OverlapBlockState() in a similar way?

MWE:

import graph_tool.all as gt
import numpy as np

g = gt.collection.data['lesmis']

state = gt.minimize_blockmodel_dl(g, state=gt.OverlapBlockState, state_args=dict(deg_corr=True, B=25))

state.draw()

This gives error:

state.draw()

NameError: name 'ones' is not defined

Many thanks,

Yes, just update to a more recent version where this bug has been fixed.

Thank you,
but it is still throws the error message.

my graph-tool version is 2.96

The code above does not throw the error, but I see it when I set deg_corr=False. I’ve fixed it in git. In the meantime, just use deg_corr=True for drawing.
