abstract DerivativeBase.convert(operator, params=None)

パラメータ

• operator (OperatorBase) – The operator we are taking the gradient, Hessian or QFI of

• params (Union[ParameterVector, ParameterExpression, List[ParameterExpression], None]) – The parameters we are taking the gradient, Hessian or QFI with respect to.

戻り値の型

OperatorBase

戻り値

An operator whose evaluation yields the gradient, Hessian or QFI.

例外

ValueError – If params contains a parameter not present in operator.
