List different implementations available for a particular MLEM type. If a subtype is not provided, list all available MLEM types.


usage: mlem types [options] [abc] [sub_type]

[ABC]       Subtype to list implementations. List subtypes if not provided
[SUB_TYPE]  Type of `meta` subtype


This command can be used to see all available MLEM classes, or to list the different implementations available for a specific SUB_TYPE (argument).

This can be useful, for example, to see which types of servers are supported for hosting and serving a model (see Examples).

Check out MLEM ABCs for a list of abstract base classes that subclass mlem.core.base.MlemABC. These constitute the building blocks of MLEM, and can be subclassed to add new functionalities and capabilities.
