[GitHub] [incubator-mxnet] fhieber opened a new issue #19348: Operator to return number of dimensions of an input

[GitBox <gi...@apache.org>]

fhieber opened a new issue #19348:
URL: https://github.com/apache/incubator-mxnet/issues/19348


   ## Description
   There is `F.shape_array()` returning the shape tuple and `F.size_array()` returning the number of elements. However, there does not seem to be a way to compute the number of dimensions of a tensor within a computation graph directly.
   
   Of course `F.size_array(F.shape_array(x))` is a possible workaround, but it would be more efficient to implement this within a single operator/kernel.
