H2O Local Context

A local H2O context allows to create objects in a locally running H2O instance. For example data tables can be converted to H2O frames and models created using H2O can be applied on those. The version of H2O used for this context can be set in the preferences. Note: If run locally, H2O shares compute resources with KNIME Analytics Platform.
