Development is best done running flowty inside of docker as this enables testing in its target environment. It also mitigates the need of setting up all the dependencies.

Using docker

The easiest way to hack on flowty is by mounting the flowty repository over the installed version in /src in the application container. e.g.

$ docker run -it --entrypoint bash \
    --runtime=nvidia \
    --mount type=bind,source=$PWD,target=/src \

One has to be careful though as flowty is installed into the global environment, and the CLI application to /usr/local/bin/flowty, so once in the bash shell, run the following:

$ python3 -m pip uninstall --yes flowty
$ python3 -m pip install -e .[test]
$ pytest

The second pip command will install flowty in editable mode, that is, it will link directly to /src so when you make changes to any files, when you invoke the tests, they will run against the updated files.
