@abc.abstractmethod
create(
    value_type: ValueType, weight_type: ValueType
) -> tff.templates.AggregationProcess

Creates a tff.aggregators.AggregationProcess with weights.

The provided value_type and weight_type are non-federated tff.Types. That is, neither is a tff.FederatedType.

The returned tff.aggregators.AggregationProcess will be created for aggregation of pairs of values matching value_type and weight_type placed at tff.CLIENTS. That is, its next method will expect type <S@SERVER, {value_type}@CLIENTS, {weight_type}@CLIENTS>, where S is the unplaced return type of its initialize method.

Args
value_type	A non-federated tff.Type.
weight_type	A non-federated tff.Type.

Returns
A tff.templates.AggregationProcess.
