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.

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.
Factory method to create a class wrapping a new NcclReduce operation.
Returns
- a new instance of NcclReduce
