Some modules have optional dependency such as
- nvflare.fuel_opt
- nvflare.app_opt
The nvflare/fuel_opt is the module with components or files which optional dependencies. That means there are dependencies are not required to be installed when user type
pip install nvflare
- you will need to install the required python package separately or use
pip install nvflare[core_opt]
to install optional dependency for core modules: the core module includes nvflare.fuel etc.
- If you are interested in CONFIG package only
pip install nvflare[CONFIG]
CONFIG is part of the core, so core_opt will include optional packages for config and other cores.
- to install optional dependency for application level module, use
pip install nvflare[apt_opt]
to install all optional dependency, use
pip install nvflare[all]
