Contribute

General contribution guidelines

  1. Fork the repository on GitHub.

  2. Install Feat on your machine.

  3. Install pytest with pip install pytest then run the tests in the repository with pytest or pytest/feat/tests/. Confirm that all tests pass on your system. If some tests fail, try to find out why they are failing. Common issues may be not having downloaded model files or missing dependencies.

  4. Create your feature.

  5. Add tests to feat/tests/.

  6. Run the tests again with pytest tests/ to make sure everything still passes, including your new feature. If you broke something, edit your feature so that it doesn’t break existing code.

  7. Create a pull request to the main repository’s master branch!

Model contribution guidelines

There are three key steps to adding a model.

  1. Create a folder for the model you are building in the appropriate model type directory. If you are contributing an Action Unit detection model and calling it mynewmodel, create a folder in feat/feat/au_detectors/. If it’s an Emotion detection model, add a folder feat/feat/emo_detectors/.

  2. Add your model architecture. Your model files could contained in a single (e.g. feat/emo_detectors/ResMaskNet/resmasknet_test.py) or they could be separated in to a model file (e.g. /au_detectors/JAANet/JAA_model) and a test file (e.g. /au_detectors/JAANet/JAA_test).

  3. Your model should be a class that has the appropriate method that the Detector can call it. For example, AU detectors should have the function mynewmodel.detect_au() that can be called.

  4. Add model to list of models in the Detector class in feat/detector.py.

  5. Upload your trained model weights to an accessible locations (e.g. Google Drive).

  6. Add tests to make sure your model is working.
