tf.raw_ops.NcclReduce

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.

Args
input A list of at least 1 Tensor objects with the same type in: half, float32, float64, int32, int64.
reduction A string from: "min", "max", "prod", "sum".
name A name for the operation (optional).
Returns
A Tensor. Has the same type as input.
