nvchai opened a new pull request #15054: Adds a fused split, bias, activation and multiplication operator URL: https://github.com/apache/incubator-mxnet/pull/15054 ## Description ## This PR adds a fused operator that fuses the split, bias addition, activation and multiplication operations. The code is a work in progress as it only implements the forward op for now and includes a dummy backward op implementation. When this operator is used for half precision tensors, it is required that the last dimension be a multiple of 2 in order to use the vectorized half type. This PR is meant to be placeholder until operator fusion method is implemented in mxnet. If the fusion method does not work out for this operator, I will try to make the operator more generic and add a graph optimization pass. ## Checklist ## ### Essentials ### Please feel free to remove inapplicable items for your PR. - [ ] Changes are complete (i.e. I finished coding on this PR) - [x] All changes have test coverage: - [ ] Code is well-documented: - [x] To the my best knowledge, examples are either not affected by this change, or have been fixed to be compatible with this change
