class saealib.Evaluator[ソース]#

ベースクラス: ABC

Base class for batch evaluators.

Methods

`__init__`
`acknowledge`	Acknowledge one contiguous update sequence.
`can_reattach`	Return whether pending work can be restored after checkpoint load.
`cancel`	Cancel submitted work when the backend supports cancellation.
`collect`	Return unacknowledged updates for a handle.
`contract`	Return the evaluator family contract.
`detach`	Detach work whose result must no longer be delivered.
`evaluate_batch`	Evaluate a batch of design vectors.
`evaluate_request`	Evaluate a request, including its public metadata boundary.
`has_partial_lifecycle_override`	Return whether lifecycle adapter methods are only partly overridden.
`reattach`	Restore a pending request or raise when unsupported.
`submit`	Submit a request through the synchronous adapter.
`supports_batch_rollback`	Return whether failed batch submission can be rolled back.
