class_docstr: MetadataCatalog provides access to "Metadata" of a given dataset.
  
  The metadata associated with a certain name is a singleton: once created,
  the metadata will stay alive and will be returned by future calls to `get(name)`.
  
  It's like global variables, so don't abuse it.
  It's meant for storing knowledge that's constant and shared across the execution
  of the program, e.g.: the class names in COCO.
docstr: Remove the metadata registered by ``name``.

      """
