espnet3.contract.stages.list_roles

source

espnet3.contract.stages.list_roles(system_cls: type) → tuple[str, ...]

Return system_cls’s config roles, in stage order, without duplicates.

Derived from each declared stage’s StageSpec.config - there is no separate, fixed role list to keep in sync with what a system actually declares.

Examples

>>> class ExampleSystem:
...     stages = (
...         StageSpec(name="train", config="training"),
...         StageSpec(name="infer", config="inference"),
...         StageSpec(name="measure", config="inference"),
...     )
>>> list_roles(ExampleSystem)
('training', 'inference')
