A TypeError: MyNetwork.__init__() missing 1 required positional argument: 'some_parameter' is thrown on the last line of the following code snippet:

class MyNetwork(nx.DiGraph):
    def __init__(self, some_parameter: str, **attr):
        super().__init__(**attr)
        self.some_parameter = some_parameter

network = MyNetwork("some_parameter")
network.add_nodes_from([1,2,3])
network.add_edges_from([(1, 2), (2, 3), (3, 1)])

sub_network = network.subgraph([2,3])

How can this be fixed? The issue seems to be that the subgraph() method which MyNetwork inherited from nx.DiGraph wants to create a new instance of MyNetwork where the constructor (in this example) requires a single parameter.
