Exception#

Exceptions that are raised by zfit.

Some are to provide a more specific error message, others are to steer the execution by raising an error that will be caught in the right place.

Exception.add_note(note) – add a note to the exception

with_traceback(object, /)#

Exception.with_traceback(tb) – set self.__traceback__ to tb and return self.

exception zfit.exception.AnalyticNotImplemented(*args)[source]#

Bases: ZfitNotImplementedError
