NoWorkFound

exception lsst.pipe.base.NoWorkFound

Bases: BaseException

An exception raised when a Quantum should not exist because there is no work for it to do.

This usually occurs because a non-optional input dataset is not present, or a spatiotemporal overlap that was conservatively predicted does not actually exist.

This inherits from BaseException because it is used to signal a case that we don’t consider a real error, even though we often want to use try/except logic to trap it.
