This is only returned when self.mode = "classification", the output consists of the
logits for classes before softmax.
node_feats = g.ndata[self.nfeat_name]
out = self.model(g, node_feats)
if self.mode == "classification":
if self.n_tasks == 1:
logits = out.view(-1, self.n_classes)
softmax_dim = 1
else:
logits = out.view(-1, self.n_tasks, self.n_classes)
softmax_dim = 2
