Contribution Guidelines#

Getting Started#

To get started with Anomalib development, follow these steps:

Fork and Clone the Repository#

First, fork the Anomalib repository by following the GitHub documentation on forking a repo. Then, clone your forked repository to your local machine and create a new branch from main.

Set Up Your Development Environment#

Set up your development environment to start contributing. This involves installing the required dependencies and setting up pre-commit hooks for code quality checks. Note that this guide assumes you are using Conda for package management. However, the steps are similar for other package managers.

Development Environment Setup Instructions
  1. Create and activate a new Conda environment:

    conda create -n anomalib_dev python=3.10
    conda activate anomalib_dev

    Install the base and development requirements:

    pip install -r requirements/installer.txt -r requirements/dev.txt
    anomalib install -v

    Optionally, for a full installation with all dependencies:

    pip install -e .[all]
  2. Install and configure pre-commit hooks:

    pre-commit install

    Pre-commit hooks help ensure code quality and consistency. After each commit, pre-commit will automatically run the configured checks for the changed file. If you would like to manually run the checks for all files, use:

    pre-commit run --all-files

    To bypass pre-commit hooks temporarily (e.g., for a work-in-progress commit), use:

    git commit -m 'WIP commit' --no-verify

    However, make sure to address any pre-commit issues before finalizing your pull request.

Making Changes#

  1. Write Code: Follow the project’s coding standards and write your code with clear intent. Ensure your code is well-documented and includes examples where appropriate. For code quality we use ruff, whose configuration is in pyproject.toml file.

  2. Add Tests: If your code includes new functionality, add corresponding tests using pytest to maintain coverage and reliability.

  3. Update Documentation: If you’ve changed APIs or added new features, update the documentation accordingly. Ensure your docstrings are clear and follow Google’s docstring guide.

  4. Pass Tests and Quality Checks: Ensure the test suite passes and that your code meets quality standards by running:

    pre-commit run --all-files
    pytest tests/
  5. Update the Changelog: For significant changes, add a summary to the CHANGELOG.

  6. Check Licensing: Ensure you own the code or have rights to use it, adhering to appropriate licensing.

  7. Sign Your Commits: Use signed commits to certify that you have the right to submit the code under the project’s license:

    git commit -S -m "Your detailed commit message"

    For more on signing commits, see GitHub’s guide on signing commits.

Submitting Pull Requests#

Once you’ve followed the above steps and are satisfied with your changes:

  1. Push your changes to your forked repository.

  2. Go to the original Anomalib repository you forked and click “New pull request”.

  3. Choose your fork and the branch with your changes to open a pull request.

  4. Fill in the pull request template with the necessary details about your changes.

We look forward to your contributions!
