Outputs a tensor containing the reduction across all input tensors.
Outputs a tensor containing the reduction across all input tensors passed to ops within the same `shared_name.
The graph should be constructed so if one op runs with shared_name value `c`, then `num_devices` ops will run with shared_name value `c`. Failure to do so will cause the graph execution to fail to complete.
input: the input to the reduction data: the value of the reduction across all `num_devices` devices. reduction: the reduction operation to perform. num_devices: The number of devices participating in this reduction. shared_name: Identifier that shared between ops of the same reduction.

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

Returns
- a new instance of NcclAllReduce
