Reduces input from num_devices using reduction to a single device.
tf.raw_ops.NcclReduce(
input, reduction, name=None
)

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.
