Description

  • Add function to utilities to validate input dimensions to Shuffle layers, returning the number of zero dimensions in the input (indicative of empty tensors)
  • Improve input validation and handling of dynamic shapes in aten::select
  • Fix bug in usage of squeezeDims regarding use_zeros argument
  • Add optional argument to squeezeDims to swap 0 and -1, as needed per the input specification
  • Add regression test case to elicit bug
  • Add test utility to compare shapes of two input tensors

Fixes #1616 [When applied with #1619]
Fixes #1622

Type of change

  • Bug fix (non-breaking change which fixes an issue)
