The library can be installed from PyPI:

pip install taskflow

Because this project has many optional (pluggable) parts like persistence backends and engines, we decided to split our requirements into two parts: - things that are absolutely required (you can't use the project without them) and things that are required by some optional part of this project (you can use the project without them). The latter requirements are provided by extras. If you want to use the feature in question, such as the worker-based engine that uses kombu, the sqlalchemy persistence backend or jobboards which have an implementation built using kazoo, you should add that requirement(s) to your project or environment. For examples, to install the worked-based engine:

pip install taskflow[workers]
