Description

Added Large Index Support for Slice and Softmax Ops and verification of Large Index support in a couple of operators. Extracted Large Vector and Tensor creation helper methods into test_utils.py

Checklist

Essentials

Please feel free to remove inapplicable items for your PR.

  • The PR title starts with [MXNET-$JIRA_ID], where $JIRA_ID refers to the relevant JIRA issue created (except PRs with tiny changes)
  • Changes are complete (i.e. I finished coding on this PR)
  • All changes have test coverage:
  • Unit tests are added for small changes to verify correctness (e.g. adding a new operator)
  • Nightly tests are added for complicated/long-running ones (e.g. changing distributed kvstore)
  • Build tests will be added for build configuration changes (e.g. adding a new build option with NCCL)
  • [] Code is well-documented:
  • For user-facing API changes, API doc string has been updated.
  • For new C++ functions in header files, their functionalities and arguments are documented.
  • For new examples, README.md is added to explain the what the example does, the source of the dataset, expected performance on test set and reference to the original paper if applicable
  • Check the API doc at http://mxnet-ci-doc.s3-accelerate.dualstack.amazonaws.com/PR-$PR_ID/$BUILD_ID/index.html
  • To the my best knowledge, examples are either not affected by this change, or have been fixed to be compatible with this change

It's a vector. So [0] isn't needed (no 2nd dimension!)

Have you tested this? Isn't np.sum(res[-1].asnumpy() == 1000) == 1?

Move this to the beginning the file before all the test methods if it is for generic use. Even better, put these util methods to a separate file.

Reviewed. Please remove tests not for 1D vector. Also, please run through the entire test file and paste the output in PR.
