Pytorch indexing

WebMatrix X represents the indices of the columns needed from matrix Y. I expect to obtain a 30x128 matrix by extracting elements from matrix Y using matrix X. Is there a way to use the indices in matrix X to extract elements from matrix Y? (I tried to implement it by using torch.gather (), but the function did not give the expected results.)
