zachgk opened a new pull request #14780: Deprecate NDArrayCollector and instead use ResourceScope URL: https://github.com/apache/incubator-mxnet/pull/14780 ## Description ## This PR now removes all usages of NDArrayCollector throughout the code and deprecates it as of the 1.5.0 release. It also updates the ResourceScope to recursively move NDArrays to outer scope when in hierarchical structure of Traversables (list, set, map, etc.) and Products (tuples). It adds a method to check if the ResourceScope contains a value and fixes a bug where moveToOuterScope would move a value to the outer scope despite it not being in the inner scope in the first place. @lanking520 @andrewfayres @nswamy ## Checklist ## ### Essentials ### Please feel free to remove inapplicable items for your PR. - [x] Changes are complete (i.e. I finished coding on this PR) - [x] 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) - [x] 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 - [x] To the my best knowledge, examples are either not affected by this change, or have been fixed to be compatible with this change
