GCN model layer dimension

[YukeWang96]

graphiler/examples/GCN/GCN.py

Lines 51 to 52 in ddba5ba

	self.layer1 = GCNLayer(in_dim, hidden_dim)
	self.layer2 = GCNLayer(out_dim, hidden_dim)

is the order for hidden_dim and out_dim in layer2 correct? or it should be reversed.

It should be reversed, sorry for the silly bug
