qiskit.opflow.gradients.Gradient.convert

Gradient.convert(operator, params=None)

Parameters

• operator (OperatorBase) – The operator we are taking the gradient of.

• params (Union[ParameterVector, ParameterExpression, List[ParameterExpression], None]) – The parameters we are taking the gradient with respect to. If not explicitly passed, they are inferred from the operator and sorted by name.

Return type

OperatorBase

Returns

An operator whose evaluation yields the Gradient.

Raises

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

• ValueError – If operator is not parameterized.
