Error with dfa in twtl code

[zserlin]

When I run the twtl code with the new lomap, I get an error where relabel_nodes doesnt seem to have the right structure, but it is correct with respect to networkx=1.11 documentation. Any ideas?

File "twtl/twtl/dfa.py", line 324, in relabel_dfa
ret.g = nx.relabel_nodes(dfa.g, mapping, copy=True)
TypeError: relabel_nodes() got an unexpected keyword argument 'copy'

It looks like the copy keyword argument defaults to True here:
https://github.com/networkx/networkx/blob/v1.11/networkx/relabel.py
You can ignore it entirely by calling it as follows: ret.g = nx.relabel_nodes(dfa.g, mapping)

*Unable to duplicate in 1.11

Test..

import networkx as nx
G = nx.Graph()
G.add_edge('A', 'B', weight=4)
G.add_edge('B', 'D', weight=2)
G.add_edge('A', 'C', weight=3)
G.add_edge('C', 'D', weight=4)
mapping = {'A':'R','B':'T','C':'Y','D':'Z'}

Without keyword copy agument

new_graph = nx.relabel_nodes(G, mapping)
print(sorted(new_graph))
['R', 'T', 'Y', 'Z']
newer_mapping = {'R':1,'T':2,'Y':3,'Z':4}

With keyword copy argument.

newer_graph = nx.relabel_nodes(new_graph, newer_mapping,copy=True)
print(sorted(newer_graph))
[1, 2, 3, 4]

Both ways of calling the function seem work fine.

networkx and python version listed below...

(env)$ pip freeze | grep networkx
