Torch.gather Backward at Alexandra Duigan blog

Torch.gather Backward. Tensor & grad, const at:: Even without abandoning determinism for index operation, perf can be improved a lot. When i use gather in forward,i get this error: Torch.nn.functional.embedding is doing what index and gather do in this case, is deterministic. The gather function gives incorrect gradients on both cpu and gpu when using repeated indices; Tensor & self, int64_t dim, const at:: Mendel1 (mengde xu) october 9, 2017, 11:42am 1. Gather (input, dim, index, *, sparse_grad = false, out = none) → tensor ¶ gathers values along an axis specified by dim. When the range of index is small in gather, the backward speed becomes very slow. Steps to reproduce the behavior: No warnings or errors are raised, and the documentation doesn't say. In other words, by configuring our script to use deterministic algorithms, we modified the default behavior of the.
