Hi there. Already running into the next problem:

$ python3
Python 3.7.3 (default, Dec 20 2019, 18:57:59) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import networkx as nx
>>> import gmatch4py as gm

  return f(*args, **kwds)
>>> g1=nx.complete_bipartite_graph(5,4) 
>>> g2=nx.complete_bipartite_graph(6,4)
>>> ged=gm.GraphEditDistance(1,1,1,1) # all edit costs are equal to 1
>>> result=ged.compare([g1,g2],None) 
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "gmatch4py/ged/abstract_graph_edit_dist.pyx", line 179, in gmatch4py.ged.abstract_graph_edit_dist.AbstractGraphEditDistance.compare

  File "gmatch4py/helpers/general.pyx", line 21, in gmatch4py.helpers.general.parsenx2graph
TypeError: 'method' object is not iterable

I have no idea why this error occurs.

Hi @philipiv and @Sciss,

Sorry for the delay ! I have no idea too... I just reinstall the library and it still works...

Python 3.8.5 (default, Jul 21 2020, 10:48:26)

g2=nx.complete_bipartite_graph(6,4)
ged=gm.GraphEditDistance(1,1,1,1) # all edit costs are equal to 1
result=ged.compare([g1,g2],None)
print(result)

On which OS did you install the library ? and which python version ?
