CollectiveReduceV2

public final class CollectiveReduceV2

Mutually reduces multiple tensors of identical type and shape.

`is_stateless` means each op does not need control dependencies to other collective ops. In this case, keys that are unique at runtime (e.g. `instance_key`) should be used to distinguish collective groups.

Inherited Methods

Public Methods

public Output<T> asOutput ()

Returns the symbolic handle of a tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public static CollectiveReduceV2.Options communicationHint (String communicationHint)

public static CollectiveReduceV2<T> create (Scope scope, Operand<T> input, Operand<Integer> groupSize, Operand<Integer> groupKey, Operand<Integer> instanceKey, Iterable<Operand<?>> orderingToken, String mergeOp, String finalOp, Options... options)

Factory method to create a class wrapping a new CollectiveReduceV2 operation.

Parameters
scope current scope
options carries optional attributes values
Returns
  • a new instance of CollectiveReduceV2
