CollectivePermute

public final class CollectivePermute

An Op to permute tensors across replicated TPU instances.

Each instance supplies its own input.

For example, suppose there are 4 TPU instances: `[A, B, C, D]`. Passing source_target_pairs=`[[0,1],[1,2],[2,3],[3,0]]` gets the outputs: `[D, A, B, C]`.

Constants

String OP_NAME The name of this op, as known by TensorFlow core engine

Public Methods

Output<T>	asOutput() Returns the symbolic handle of the tensor.
static <T extends TType> CollectivePermute<T>	create(Scope scope, Operand<T> input, Operand<TInt32> sourceTargetPairs) Factory method to create a class wrapping a new CollectivePermute operation.
Output<T>	output() The permuted input.

Constant Value: "CollectivePermute"

Public Methods

public Output<T> asOutput ()

Returns the symbolic handle of the 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 CollectivePermute<T> create (Scope scope, Operand<T> input, Operand<TInt32> sourceTargetPairs)

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

Parameters

scope	current scope
input	The local input to be permuted. Currently only supports float and bfloat16.
sourceTargetPairs	A tensor with shape [num_pairs, 2].

Returns

a new instance of CollectivePermute

public Output<T> output ()

The permuted input.
