[GitHub] [incubator-mxnet] kpuatamazon opened a new issue #19245: Performance: avoid memory allocation in MXNDArrayAt

kpuatamazon opened a new issue #19245:
URL: https://github.com/apache/incubator-mxnet/issues/19245


   ## Description
   
   I think all `MXNDArrayAt` and `MXNDArrayAt64` is index an array to (eventually) return a scalar.  An operation users might call frequently.  It should not require memory allocation, yet the current code creates a `new NDArray` that in turn allocates its own buffer.
