nvchai opened a new pull request #15044: [WIP] Added fused slice sum operator
URL: https://github.com/apache/incubator-mxnet/pull/15044
 
 
   ## Description ##
   This PR adds a fused slice sum operator that fuses the slice operation with a sum operation. The code is a work in progress as it only implements the forward op for now and includes a dummy backward op implementation. When the slice_sum 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.
