Contributing Guidelines

Thank you for your interest in contributing to our project. Whether it's a bug report, new feature, correction, or additional documentation, we greatly value feedback and contributions from our community.

Please read through this document before submitting any issues or pull requests to ensure we have all the necessary information to effectively respond to your bug report or contribution.

Reporting Bugs/Feature Requests

We welcome you to use the GitHub issue tracker to report bugs or suggest features.

When filing an issue, please check existing open, or recently closed, issues to make sure somebody else hasn't already reported the issue. Please try to include as much information as you can. Details like these are incredibly useful:

  • A reproducible test case or series of steps
  • The version of our code being used
  • Any modifications you've made relevant to the bug
  • A description of your environment or deployment

Contributing via Pull Requests

Contributions via pull requests are much appreciated.

You can use the following commands to setup your developing and testing environment after you fork sagemaker-python-sdk repository:

git clone [email protected]:<your-github-username>/sagemaker-python-sdk.git
cd sagemaker-python-sdk
pip install -U .
pip install -U .[test]

Before sending us a pull request, please ensure that:

  1. You are working against the latest source on the master branch.
  2. You check existing open, and recently merged, pull requests to make sure someone else hasn't addressed the problem already.
  3. You open an issue to discuss any significant work - we would hate for your time to be wasted.

To send us a pull request, please:

  1. Fork the repository.
  2. Modify the source; please focus on the specific change you are contributing. If you also reformat all the code, it will be hard for us to focus on your change.
  3. Include unit tests when you contribute new features or make bug fixes, as they help to a) prove that your code works correctly, and b) guard against future breaking changes to lower the maintenance cost.
  4. Ensure local tests pass.
  5. Use commit messages (and PR titles) that follow these guidelines.
  6. Send us a pull request, answering any default questions in the pull request interface.
  7. Pay attention to any automated CI failures reported in the pull request, and stay involved in the conversation.

GitHub provides additional document on forking a repository and creating a pull request.

Commit message guidelines

We use commit messages to update the project version number and generate changelog entries, so it's important for them to follow the right format. Valid commit messages include a prefix, separated from the rest of the message by a colon and a space. Here are a few examples:

feature: support VPC config for hyperparameter tuning
fix: fix flake8 errors
documentation: add MXNet documentation

Valid prefixes are listed in the table below.

Prefix Use for...
breaking Incompatible API changes.
deprecation Deprecating an existing API or feature, or removing something that was previously deprecated.
feature Adding a new feature.
fix Bug fixes.
change Any other code change.
documentation Documentation changes.

Some of the prefixes allow abbreviation -- break, feat, depr, and doc are all valid. If you omit a prefix, the commit will be treated as a change.

For the rest of the message, use imperative style and keep things concise but informative. See How to Write a Git Commit Message for guidance.

Integration tests

Our CI system runs integration tests (the ones in the tests/integ directory) in parallel. If you are writing or modifying a test that creates a SageMaker job (training, tuner, or transform) or an endpoint, it's important to assign a concurrency-friendly job_name (or endpoint_name), or your tests may fail randomly due to name collisions. We have a helper method sagemaker.utils.unique_name_from_base(base, max_length) that makes test-friendly names. You can find examples of how to use it here and here, or by searching for "unique_name_from_base" in our test code.

Finding contributions to work on

Looking at the existing issues is a great way to find something to contribute on. As our projects, by default, use the default GitHub issue labels ((enhancement/bug/duplicate/help wanted/invalid/question/wontfix), looking at any 'help wanted' issues is a great place to start.

Code of Conduct

This project has adopted the Amazon Open Source Code of Conduct. For more information see the Code of Conduct FAQ or contact [email protected] with any additional questions or comments.

Security issue notifications

If you discover a potential security issue in this project we ask that you notify AWS/Amazon Security via our vulnerability reporting page. Please do not create a public github issue.

Licensing

See the LICENSE file for our project's licensing. We will ask you to confirm the licensing of your contribution.

We may ask you to sign a Contributor License Agreement (CLA) for larger changes.
