Can't supply argument bs != None to gt.minimize_nested_blockmodel_dl
I'm running latest version, installed via Ubuntu's apt-get.
I want to initialize the nested state with a given hierarchy. The following of course is pointless, but is how the mechanics should work (?):
>>> from graph_tool import *
>>> import graph_tool.all as gt
>>> g = gt.collection.data["football"]
>>> g
<Graph object, undirected, with 115 vertices and 613 edges at 0x7fe79ade6630>
>>> state = gt.minimize_nested_blockmodel_dl(g)
>>> bs = state.get_bs()
>>> state2 = gt.minimize_nested_blockmodel_dl(g, bs=bs)
Traceback (most recent call last):
