DLHub home_run

home_run is a tool used by the Data and Learning Hub for Science internally to turn a bunch of files and a recipe into an functional Python object.

Installation

home_run is on PyPi. Install it by calling

pip install home_run

home_run is designed to be as light-weight as possible, and has only requests as a dependency.

Technical Details

The key ingredients for using home_run are files describing a function that will be served by DLHub. These include a metadata file describing the servable (see dlhub_sdk for tools for creating these files, and dlhub_schemas for the schemas), and the actual files that make up the servable (e.g., a Keras hdf5 file).

Each particular type of servable has its own recipe for going from these files to a Python object. All recipes are a subclass of BaseServable, which provides the general framework for defining a servable object. Each subclass has a matching BaseMetadataModel class in dlhub_sdk. For example, the type of servable that can be described by the PythonStaticMethodModel can be run by the PythonStaticMethodServable.
