How to convert adjacency matrix to edge_index format?

[Andre_Amaral_IST (André Amaral)]

I found a way to do it:

Adjacency Matrix to Edge Index (Solution)

Hey, For those who have this question, here you have a way to solve it! adj_t = torch.tensor([[0,1,0,0],[1,0,0,0], [1,0,0,1], [0,0,1,0]]) edge_index = adj_t.nonzero().t().contiguous() >>> tensor([[0, 1, 2, 2, 3], [1, 0, 0, 3, 2]]) Thanks for your attention, André Amaral

Hope it helps!
