NcclReduce

public final class 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.

Public Methods

Output<T>
asOutput()
Returns the symbolic handle of a tensor.
static <T extends Number> NcclReduce<T>
create(Scope scope, Iterable<Operand<T>> input, String reduction)
Factory method to create a class wrapping a new NcclReduce operation.

Inherited Methods

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 NcclReduce<T> create (Scope scope, Iterable<Operand<T>> input, String reduction)

Factory method to create a class wrapping a new NcclReduce operation.

Parameters
scope current scope
Returns
  • a new instance of NcclReduce
