Reduces `input` from `num_devices` using `reduction` to a single device.
Reduces `input` from `num_devices` using `reduction` to a single device.
The graph should be constructed so that all inputs have a valid device assignment, and the op itself is assigned one of these devices.
input: The input to the reduction. data: the value of the reduction across all `num_devices` devices. reduction: the reduction operation to perform.

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 NcclReduce <T> create ( Scope scope, Iterable< Operand <T>> input, String reduction)
Factory method to create a class wrapping a new NcclReduce operation.
Parameters
scope | current scope |

Returns
- a new instance of NcclReduce
