Helper library for creating Runway models

Project description

CircleCI branch docs codecov

The Runway Model SDK allows you to port new and existing machine learning models to the Runway platform. With a few lines of code, you can modify your Python model to be used and shared by others on Runway.


The SDK supports Python 3.6+. You can install the module using either pip or pip3 like so:

pip3 install runway-python

Now head over to the sdk docs to learn how to use the Runway Model SDK.


Reference and documentation for the Runway Model SDK is hosted at These docs provide an overview of how to use the SDK to port your own ML models.

The Runway Model Template repo also contains a simple example of how to get started porting a model to Runway.

See the Importing Models into Runway tutorial for a walk-through illustrating how to port a model to Runway.


If you'd like to contribute to the development of the Runway Python SDK, you can clone and modify this repository by following the instructions below.

git clone runway-model-sdk
cd runway-model-sdk

## optionally use a virtual environment
# virtualenv -p python3 venv && source venv/bin/activate

# install dependencies
python3 install

# install the dev dependencies
make dev


Automated tests for the Runway Model SDK are written using pytest and live in the tests/ directory. We also provide support for code coverage via pytest-cov.

## Create and activate a python3 virtual environment if you need to.
# virtualenv -p python3 venv && source ./venv/bin/activate

# make sure you have the development dependencies installed
make dev

# run the tests
make test

# by default pytest suppresses stdout and stderr during testing, so run tests
# like this if you'd like to see the output from your print() statements during
# testing
make test-debug

# to generate coverage statistics while running tests, use this command.
# it prints test coverage to the console and also generates a more detailed HTML
# report in htmlcov/.
make coverage

If you make a PR against this repo, please be sure to include automated tests to validate that your code works as expected. PRs will be automatically blocked by a Codecov bot if their changes reduce the overall test coverage of the Runway Model SDK package.

Building the Docs

The Model SDK documentation is generated from inline source code using docstrings, Sphinx, and a modified Read the Docs HTML theme. The version of Sphinx that we are using (v2.0.1) requires Python 3.

## Create and activate a python3 virtual environment if you need to.
# virtualenv -p python3 venv && source ./venv/bin/activate

# make sure you have the docs dependencies installed
make dev-docs

# build the docs
make docs

Your auto-generated HTML docs should now appear in docs/build/html.


We have a #model-sdk channel in our public Slack workspace that you can use to ask questions or chat with the Runway team about this Python module. Feel free to open an issue as well!
