FrozenLocalStateRequest

class penzai.deprecated.v1.data_effects.local_state.FrozenLocalStateRequest

Bases: Generic[_T], EffectRequest

Effect request for local state with a frozen value.

This can be used to store the state for a stateful model after it has been initialized and possibly updated. As a convenience, it’s possible to call get on a FrozenLocalStateRequest, but not set.

Variables:

• state (_T) – Frozen version of the state for this effect.

• category (Category) – Category tag identifying the kind of state.

• name (str | None) – Optional name for this state. If provided, it will be renamed as if this state was a parameter, and used as the key for this state in the state dictionary. If not provided, a name will be inferred from the PyTree structure.
