2 Open Source Deep Learning Platform 2 DAILY Mo n d a y Throughout our conversations with these developers, one message became clear, a platform’s community is its greatest strength. Community support and contributions allow a platform to have the greatest impact ; however, severalof thedevelopersacknowledged that the community often does not fully appreciate thedifficulties associated with maintaining and contributing code to a project. Whether a contribution is coming from a lead developer or a new developer, it must be rigorously evaluated. All code must support multiple operating systems and machine configurations, coding style requirements, coding best practices, and multiple use cases. Typically numerous public and private discussions, code revisions, and documentation updates must occur as a contribution is processed, and the person who is submitting a contribution must ultimately take responsibility for ensuring that their contribution progresses through that process and concludes successfully. So, how can you become an open source developer, help your research have maximum impact, and enjoy the challenges of high quality software processes that support community development? The ITK and MONAI developers offered several suggestions, and the two most prominent were the following. First, consider that there are many ways to contribute: communicating your ideas to members of the working groups; submitting issues, feature requests, and bug reports; improving documentation; creating new tutorials; conducting code reviews for pending pull requests; and contributing bug fixes as well as new algorithms. Second, when making any contribution, be it a bug report or new algorithm, please take the time to learn the contribution procedures of the project: identify and use the proper forums, follow reporting and code templates when appropriate, and monitor and support the progression of your contribution through those procedures. Clearly, becoming an open source software developer is not for everyone, but we welcome you to join the MONAI and ITK communities, and we look forward to your contributions in whatever form they take! These open platforms include well established, general purpose systems such as PyTorch and the Insight Toolkit (ITK), as well as cutting-edge, domain specific systems such as the Medical Open Network for AI (MONAI)
