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

Parameters:

scope - current scope

input -

groupSize -

groupKey -

instanceKey -

mergeOp -

finalOp -

subdivOffsets -

options - carries optional attributes values

Returns:

a new instance of AllReduce

waitFor

public static AllReduce.Options waitFor(List<Long> waitFor)

Parameters:

waitFor -

communicationHint

public static AllReduce.Options communicationHint(String communicationHint)

Parameters:

communicationHint -

data

public Output<T> data()

asOutput

public Output<T> asOutput()

Description copied from interface: Operand

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.

Specified by:

asOutput in interface Operand<T extends Number>
