Hi, I want to know why the adjacency matrix is normalized by ``` self.adjacency = adj.multiply(1.0/adj.sum(axis=0).reshape(1, -1)) ``` rather than ``` self.adjacency = adj.multiply(1.0/adj.sum(axis=1).reshape(-1, 1)) ``` following the Equation (1)....

Can you please provide the code for data processing? Thanks.
