In the API documentation ：
the API GATConv doesn’t contain a parameter called num-hidden
however, in the GAT example of pytorch, there is a num-hidden
Besides, the argparse part in train.py use ‘num-hidden’ rather than ‘num_hidden’, but the code still works, why was that?
I’m confused about the meaning of these parameter , whether is it needed and are ‘num-hidden’ and ‘num_hidden’ the same?
