Contributing to Anomalib

We welcome your input! 👐

We want to make it as simple and straightforward as possible to contribute to this project, whether it is a:

  • Bug Report
  • Discussion
  • Feature Request
  • Creating a Pull Request (PR)
  • Becoming a maintainer

Bug Report

We use GitHub issues to track the bugs. Report a bug by using our Bug Report Template in Issues.

Discussion

We enabled GitHub Discussions in anomalib to welcome the community to ask questions and/or propose ideas/solutions. This will not only provide a medium to the community to discuss about anomalib but also help us de-clutter Issues.

Feature Request

We utilize GitHub issues to track the feature requests as well. If you are certain regarding the feature you are interested and have a solid proposal, you could then create the feature request by using our Feature Request Template in Issues. If it's still in an idea phase, you could then discuss that with the community in our Discussion.

Development & PRs

We actively welcome your pull requests:

 Getting Started

1. 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.

2. 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
  2. Install the development requirements:

    # Option I: Via anomalib install
    anomalib install --option dev
    
    #Option II: Via pip install
    pip install -e .[dev]

    Optionally, for a full installation with all dependencies:

    # Option I: via anomalib install
    anomalib install --option full
    
    # Option II: via pip install
    pip install -e .[full]
  3. 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!
