Description

1. fix flaky test #11685
2. Pass 10,000 runs.
3. Root cause explained:

In this unit test, during testing of mx.sym.maximum and minimum. It didn't cover the case when x and y is equal.
See Line 100
when x = y, the following line

lambda g, x, y: (g * (x>y), g * (y>x)

will return (0, 0) when the correct value should be (1, 0)

In MXNet symbolic implementation, mx.sym.maximum and minimum is using the following logic for element-wise comparison:

maximum is using (greater or equal, less than) see here
minimum is using (less or equal, greater than) see here

Modified accordingly and removed fixed seed.

Checklist

Essentials

Please feel free to remove inapplicable items for your PR.

  • The PR title starts with MXNET-774
  • 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

Changes

  1. fixed gradient condition
  2. removed fixed seed

Comments

  • If this change is a backward incompatible change, why must this change be made.
  • Interesting edge cases to note here

[MXNET-703] TensorRT runtime integration (apache#11325)

* [MXNET-703] TensorRT runtime integration

Co-authored-by: Clement Fuji-Tsang <caenorst@hotmail.com>

* correctly assign self._optimized_symbol in executor

* declare GetTrtCompatibleSubsets and ReplaceSubgraph only if MXNET_USE_TENSORRT

* add comments in ReplaceSubgraph

* Addressing Haibin's code review points

* Check that shared_buffer is not empty when USE_TENSORRT is set

* Added check that TensorRT binding is for inference only

* Removed redundant decl.

* WIP Refactored TRT integration and tests

* Add more build guards, remove unused code

* Remove ccache report

* Remove redundant const in declaration

* Clean Cmake TRT files

* Remove TensorRT env var usage

We don't want to use environment variables with TensorRT yet, the
logic being that we want to try and have as much fwd compatiblity as
possible when working on an experimental feature.  Were we to add
env vars they would have to be gaurenteed to work in the future until
a major version change.  Moving the functionality to a contrib call
reduces this risk.

* Use contrib optimize_graph instaed of bind

* Clean up cycle detector

* Convert lenet test to contrib optimize

* Protect interface with trt build flag

* Fix whitespace issues

* Add another build guard to c_api

* Move get_optimized_symbol to contrib area

* Ignore gz files in test folder

* Make trt optimization implicit

* Remove unused declaration

* Replace build guards with runtime errors

* Change default value of TensorRT to off

This is change applies to both TensorRT and non-TensorRT builds.

* Warn user when TRT not active at runtime

* Move TensorRTBind declaration, add descriptive errors

* Test TensorRT graph execution, fix bugs

* Fix lint and whitespace issues

* Fix typo

* Removed default value for set_use_tensorrt

* Improved documentation and fixed spacing issues

* Move static exec funcs to util files

* Update comments to match util style

* Apply const to loop element

* Fix a few namespace issues

* Make static funcs inline to avoid compiler warning

* Remove unused inference code from lenet5_train

* Add explicit trt contrib bind, update tests to use it

* Rename trt bind call

* Remove documentation that is not needed for trt

* Reorder arguments, allow position calling

Decrease success rate to make test more stable (apache#12092)

I have added this test back to unit test coverage and decreased success rate even more, to make sure that fails would happen even more rare

Add Clojure to website nav (apache#12075)

* adding clojure to API navigation

* adding clojure to the sidebar

* switched order

[MXNET-703] Use relative path for symbol import (apache#12124)

Fix shared memory with gluon dataloader, add option pin_memory (apache#11908)

* fix as_in_context if not cpu_pinned

* fix cpu_pinned

* fix unittest for windows, update doc that windows mp is available

* fix pin_memory

* fix lint

* [MXAPPS-805] Notebook execution failures in CI.

* Add a retry policy when starting a notebook executor to handle the failure to
 start a notebook executor (due to a port collision, kernel taking too
 long to start, etc.).

* Change logging level for tests to INFO so that we have more
 informative test output.

* Make retry logic for Jupyter notebook execution specific to the error
message we are looking for to prevent false positives in the retry logic.

* Fix flaky test for kl_loss

* remove comment.

[MXNET-788] Fix for issue apache#11733 pooling op test (apache#12067)

* added support to check_consistency function to generate random numbers for a specific datatype (ie. fp16)
this ensures that for tests that compare results among different precisions, that data is generated in the least precise type and casted to the most precise

changed test_pooling_with_type test case to specify fp16 precision for random input data
renamed the 2nd test_pooling_with_type function to test_pooling_with_type2 so it doesnt redefine the first and both are tested

fixed equation formatting issue in pooling operator description

Added myself to the contributors readme file

* updated from latest in master (had old version of the file)

* shortened lines per lint spec

* renamed default_type argument to rand_type for clarity
updated function docstring with argument description

removed rand_type setting for non-max pooling tests

* cleaned up check_consistency function docstring

alternative fix.
