MultiDiGraph doesn't work

[giammy677dev]

Hi,
I'm trying to use your algorithm with a NetworkX MultiDiGraph but I obtain the following error:

MultiDiGraph with 97 nodes and 506 edges
concurrent.futures.process._RemoteTraceback:
"""
Traceback (most recent call last):
line 256, in process_worker
r = call_item.fn(*call_item.args, **call_item.kwargs)

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
line 370, in choice
raise IndexError('Cannot choose from an empty sequence')
IndexError: Cannot choose from an empty sequence
"""

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
line 48, in
rwc_score = get_rwc(G, republican_nodes, democratic_nodes, node_percentage, number_simulations)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

line 449, in result
return self.__get_result()
^^^^^^^^^^^^^^^^^^^
line 401, in __get_result
raise self._exception
IndexError: Cannot choose from an empty sequence

Process finished with exit code 1

Do you know how can I solve?
