Add boolean ndarray #15940

reminisce · 2019-08-19T06:24:11Z

Description

Added boolean ndarray infra in mshadow.
Implemented comparison operators: equal, not_equal, greater, greater_equal, less, and less_equal to use np.bool_ as their output tensors' dtype.

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

Comments

Follow-up work includes:

More operators that can consume boolean ndarrays. To list a few that must be finished before the next release:
- sum
- cast
- boolean_mask
ndarray boolean indexing

Thank @yzhliu @hzfan for the help on debugging.

+  values[0].v_handle = const_cast<DLTensor*>(&(tblobs[0].dltensor()));

+  // scalar param
+  type_codes[1] = kDLFloat;


@yzhliu Since I need to pass a double param to the op func generated by TVM, I cannot use the Call function defined in the TVMOpModule. I moved the logic of preparing TVMArgs up here from the Call function to MXNet op's FCompute function and added an independent CallEx in TVMOpModule to just invoke the kernel. We can discuss the change of the API to cater for more use cases.

Any particular reason you are introducing a second set instead of using the arch set variable we already have? In which use case would these two differ?

Reverted. Thanks for the suggestion.

would using https://docs.python.org/3.7/library/itertools.html#itertools.product help readability of the code and make it less nested?

Thanks for the suggestion. Will consider refactoring it in the following PRs.
