ZhennanQin opened a new pull request #13697: [MKLDNN] Enable signed int8 support for convolution. URL: https://github.com/apache/incubator-mxnet/pull/13697 ## Description ## Major changes: * Integrate mkldnn signed int8 convolution. * Introduce new quantization flow out_type `auto`, which determines the out_type according to calibration information. If negative value is detected from calibration min, out_type will be int8, otherwise, out_type will be uint8. * Introduce new operator quantize_v2, which only has 1 input data and will self-calculate min/max in runtime or use calibration information set by parameters. It also used to implement out_type `auto`. * Add new parameter `monitor_all` for monitor module to allow monitoring both input & output of operators. This is used for collecting calibration information of in_data to support quantize first layer of graph. ## Checklist ## ### Essentials ### Please feel free to remove inapplicable items for your PR. - [ ] The PR title starts with [MXNET-$JIRA_ID], where $JIRA_ID refers to the relevant [JIRA issue](https://issues.apache.org/jira/projects/MXNET/issues) created (except PRs with tiny changes) - [ ] Changes are complete (i.e. I finished coding on this PR) - [ ] All changes have test coverage: - Unit tests are added for small changes to verify correctness (e.g. adding a new operator) - Nightly tests are added for complicated/long-running ones (e.g. changing distributed kvstore) - Build tests will be added for build configuration changes (e.g. adding a new build option with NCCL) - [ ] Code is well-documented: - For user-facing API changes, API doc string has been updated. - For new C++ functions in header files, their functionalities and arguments are documented. - For new examples, README.md is added to explain the what the example does, the source of the dataset, expected performance on test set and reference to the original paper if applicable - Check the API doc at http://mxnet-ci-doc.s3-accelerate.dualstack.amazonaws.com/PR-$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
