Subcommand

class Subcommand(Registrable)

An abstract class representing subcommands for allennlp.run. If you wanted to (for example) create your own custom special-evaluate command to use like

allennlp special-evaluate ...

you would create a Subcommand subclass and then pass it as an override to main.

requires_plugins

class Subcommand(Registrable):
 | ...
 | requires_plugins: bool = True

If True, the sub-command will trigger a call to import_plugins() (except for custom subcommands which come from plugins, since plugins will already have been imported by the time the subcommand is discovered), and will also have an additional --include-package flag.

add_subparser

class Subcommand(Registrable):
 | ...
 | def add_subparser(
 |     self,
 |     parser: argparse._SubParsersAction
 | ) -> argparse.ArgumentParser

register

class Subcommand(Registrable):
 | ...
 | @classmethod
 | @overrides
 | def register(
 |     cls: Type[T],
 |     name: str,
 |     constructor: Optional[str] = None,
 |     exist_ok: bool = False
 | ) -> Callable[[Type[T]], Type[T]]

name

class Subcommand(Registrable):
 | ...
 | @property
 | def name(self) -> str
