Hello. While I run the following code
https://github.com/Yaxin-Cui/Graph-Neural-Network/blob/main/code/graphstellar_updated.py

I am getting the following error
graphstellar_updated.py:441: DeprecationWarning: Constructing a StellarGraph directly from a NetworkX graph has been replaced by the StellarGraph.from_networkx function G_train = sg.StellarGraph(G_train, node_features="feature")

Can you please help me to see what I should modify in the script to NOT get that error. Thanks in advance!
