I am using GCN from Steller Graph with Cora dataset from CSV files (not default dataset). It gives me an error: raise KeyError(missing_values) at train_gen = generator.flow(train_subjects.index, train_targets).
The error is given below. Also, the link to the code is here. Any idea how to resolve the issue?
