Gatconv concat false
Webconcat ( bool, optional) – If set to True, will concatenate current node features with aggregated ones. (default: False) bias ( bool, optional) – If set to False, the layer will not learn an additive bias. (default: True) **kwargs ( optional) – Additional arguments of torch_geometric.nn.conv.MessagePassing. WebIt seems that it fails because of edge_index_i in the message arguments. With the small following test:
