MacOS is weird and its CPU flags are separated in two separate fields returned by the sysctl interface. To get around this, we need to test both of them, so here goes

Allow for dynamic gradient scaling to fade out after N updates

(#894)

This parallelizes data reading. On very fast GPUs and with small models training speed can be starved by too slow batch creation. Use --data-threads 8 or more, by default currently set to 1 for backcompat.

* Add GCC 11 support
Some C++ Standard Library headers have been changed to no longer include other headers that they do need to depend on. As such, C++ programs that used standard library components without including the right headers will no longer compile.
The following headers are used less widely in libstdc++ and may need to be included explicitly when compiled with GCC 11:
<limits> (for std::numeric_limits)
<memory> (for std::unique_ptr, std::shared_ptr etc.)
<utility> (for std::pair, std::tuple_size, std::index_sequence etc.)
<thread> (for members of namespace std::this_thread.)

failed in macOS (#872)
Co-authored-by: Roman Grundkiewicz <rgrundkiewicz@gmail.com>

This adds Top-K sampling to Marian and extends the --output-sampling option to take arguments
|
|
|
|
This PR improves clipping and pruning behavior of NaNs and Infs during fp16 training, ultimately avoiding the underflow problems that we were facing so far.
|
|
Marian does not compile on macOS 11.6, so the build has stopped working due to an upgrade from macOS-10.15 to macOS 11.6 in Azure Pipelines: https://github.com/actions/virtual-environments/issues/4060
This PR explicitly set macOS 10.15 in the workflow.

* Add --allow-unauthenticated when installing CUDA
* Remove workflow with Ubuntu 16.04
|

With final space this eliminates trailing whitespace caused by appending EOS
|
|
- Add `--allow-unauthenticated` to `apt` when installing CUDA on Ubuntu
- Removing `ubuntu-16.04` image from Azure pipelines, which will become unavailable after September 20
|
|
This PR adds a checkbox which can be unchecked to skip running compilation checks when triggering them manually. It is useful for generating expected outputs on different CPUs for tests using 8-bit models.

* crossMask not used by default
* added an option to better clarify when choosing factor predictor options
* fixed bug when choosing re-embedding option and not setting embedding size
* avoid uncessary string copy
* Check in factors documentation
* Fix duplication in merge
* Self-referential repository

* Add explicit error msg if using concat on target
* Update func comments. Fix spaces
* Add Marian version requirement

Update SPM in Marian
|
|
The changes proposed in this pull request:
* Added regression testing with internal models into Azure Pipelines on both Windows and Ubuntu
* Created https://machinetranslation.visualstudio.com/Marian/_git/marian-prod-tests (more tests will be added over time)
* Made regression test outputs (all `.log`, `.out`, `.diff` files) available for inspection as a downloadable artifact.
* Made `--build-info` option available in CMake-based Windows builds
Warning: I tried to handle multiple cases, but some regression tests may occasionally fail, especially tests using avx2 or avx512 models, because the outputs are system/CPU dependent. I think it's better to merge this already, monitoring the stability of tests, and adding expected outputs variations if necessary, improving the coverage and stability of regression tests over time.

set guided alignments
This change allows marking SentenceTuples as 'altered', if they were generated or modified by data augmentation internally in such a way so as to impact processing. In particular, for such sentence tuples, we do not want to try setting guided alignments if the externally provided guided alignments might no longer be correct after that alteration.

Small changes to make the LSH work with Leaf server and QuickSand.
