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

reduction | A string from: "min", "max", "prod", "sum". |
name | A name for the operation (optional). |
