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

Coud you add this file to https://github.com/apache/incubator-mxnet/blob/master/tests/nightly/apache_rat_license_check/rat-excludes to pass license check?

@eric-haibin-lin the unix gpu failed on a dropout_perf test. Have you even seen it before? I am a bit struggling to find the root cause of it.

eric-haibin-lin · 2019-01-19T05:16:55Z

The failure does not seem related. I've triggered the test again to see if it passes this time

Looks good pending one minor comment

@rondogency Could you take a look at those warnings introduced by this PR? If possible we need get rid of them.
