DeepSpeed welcomes your contributions!
DeepSpeed uses pre-commit to ensure that formatting is
consistent across DeepSpeed. First, ensure that
pre-commit is installed from either
installing DeepSpeed or
pip install pre-commit. Next, the pre-commit hooks must be
installed once before commits can be made:
Afterwards, our suite of formatting tests run automatically before each
git commit. You
can also run these manually:
pre-commit run --all-files
If a formatting test fails, it will fix the modified code in place and abort
git commit. After looking over the changes, you can
git add <modified files>
and then repeat the previous
git commit command.
DeepSpeed tracks two types of tests: unit tests and more costly model convergence tests.
The model convergence tests train
DeepSpeedExamples and measure
end-to-end convergence and related metrics. Unit tests are found in
the model convergence tests are found in
PyTest is used to execute tests. PyTest can be
installed from PyPI via
pip install pytest. Simply invoke
pytest --forked to run the
pytest --forked tests/unit/
You can also provide the
-v flag to
pytest to see additional information about the
tests. Note that pytest-forked and the
--forked flag are required to test CUDA functionality in distributed tests.
Model tests require four GPUs and training data downloaded for DeepSpeedExamples.
Note that the
--forked flag is not necessary for the model tests.
