I get the error above when running the following code. why is that?

from peregrinearb import create_weighted_multi_exchange_digraph, bellman_ford_multi, print_profit_opportunity_for_path_multi

graph = create_weighted_multi_exchange_digraph(['bittrex', 'binance', 'huobi', 'kucoin'], log=True)
graph, paths = bellman_ford_multi(graph, 'BTC')
for path in paths:
    print_profit_opportunity_for_path_multi(graph, path)

This is because you are using the wrong fork of networkx. You should use mine, the one listed in setup.py.
