Open-Unmix is designed as scientific software. Therefore, we encourage the community to submit bug-fixes and comments and improve the computational performance, reproducibility and the readability of the code where possible. When contributing to this repository, please first discuss the change you wish to make in the issue tracker with the owners of this repository before making a change.

We are not looking for contributions that only focus on improving the separation performance. However, if this is case, we, instead, encourage researchers to

  1. Use Open-Unmix for their own research, e.g. by modification of the model.
  2. Publish and present the results in a scientific paper / conference and cite open-unmix.
  3. Contact us via mail or open a performance issue if you are interested to contribute the new model. In this case we will rerun the training on our internal cluster and update the pre-trained weights accordingly.

Please note we have a code of conduct, please follow it in all your interactions with the project.

Pull Request Process

The preferred way to contribute to open-unmix is to fork the main repository on GitHub:

  1. Fork the project repository: click on the 'Fork' button near the top of the page. This creates a copy of the code under your account on the GitHub server.

  2. Clone this copy to your local disk:

$ git clone
$ cd open-unmix-pytorch
  1. Create a branch to hold your changes:
$ git checkout -b my-feature

and start making changes. Never work in the master branch!

  1. Ensure any install or build artifacts are removed before making the pull request.

  2. Update the and/or the appropriate document in the /docs folder with details of changes to the interface, this includes new command line arguments, dataset description or command line examples.

  3. Work on this copy on your computer using Git to do the version control. When you're done editing, do:

$ git add modified_files
$ git commit

to record your changes in Git, then push them to GitHub with:

$ git push -u origin my-feature

Finally, go to the web page of your fork of the open-unmix repo, and click 'Pull request' to send your changes to the maintainers for review. This will send an email to the committers.

(If any of the above seems like magic to you, then look up the Git documentation on the web.)
