input_layer puzzled

[lxlsu]

Hi,
I've seen the paper, Nevae, paper showed that the C_u(k) aggregates from t_u(atom type) , x_u（coordinates）and weight(bond type),while codes(layer.py, input_layer function) showed that c_x aggregates from adj, weight, and degree feature. confusing me.
sorry to bother you. hope your reply. thank you.
