Unity Catalog Registered Models API

Registered models are machine learning models that are stored within the Unity Catalog model registry. They are comprised of all versions of a single model that a user wishes to keep. A registered model resides in the third layer of Unity Catalog’s three-level namespace, and can be referenced with the form __catalog_name__.__schema_name__.__model_name__.
