Question on code of SemiGNN

[blackboxo]

for generating u_i, u_j in SemiGNN, the code at line 187 in utils.py

for index in range(0, num_of_nodes):
        u_i.append(pairs[index][0])
        u_j.append(pairs[index][1])

the length of num_of_nodes is not the same as the length of pairs. It cann't iterate all pairs.
