WebJun 3, 2024 · Find an answer below, playing with several pytorch methods ( torch.eq (), torch.unique (), torch.sort (), etc.) in order to output a compact, sliced tensor of shape (len (idx), len (idx)). I tested several edge cases (unordered idx, v with 0 s, i with multiple same index pairs, etc.), though I may have forgot some.
