WebJul 22, 2024 · The task I have is to do dist.gather on tensors of variable size. This happens during prediction stage: often multiple tensors size differ from others by 1. The idea was to pass tensor sizes to destination rank, use these sizes to prepare gather_list and now do dist.gather having proper tensor sizes. WebA question about matrix indexing : r/pytorch. 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. thonny python github
