E.g. if argmax () returns 10 and you’ve got 4 columns, you know it’s on row 2, column 2. You can use Python’s divmod for this a = torch.randn (10, 10) row, col = divmod (a.argmax ().item (), a.shape [1]) porth community school badge

Eddie_Han. I have two matrices, X and Y, with sizes of 12225x30 and 12225x128, respectively. Matrix 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.

The indices are not limited to 1D tensors, but they all need to have the same size and each element is used as one index, for example with 2D tensors the indexing happens as data[indices_dim0[i][j], indices_dim1[i][j]] With 2D tensors it happens to be much simpler to create the batch indices without having to do it manually.
