create

@Endpoint(describeByClass=true)
public static XlaHostCompute create(Scope scope,
 Iterable<Operand<?>> inputs,
 List<Class<? extends TType>> Toutputs,
 List<String> ancestors,
 List<Shape> shapes,
 ConcreteFunction shapeInferenceGraph,
 String key,
 XlaHostCompute.Options... options)

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

Parameters:

scope - current scope

inputs - A list of tensors that will be sent to the host.

Toutputs - The element types of each element in outputs.

ancestors - A list of names of HostCompute computations that must be sequenced before this computation.

shapes - If shape_inference_graph is empty, a list of the shapes of outputs.

shapeInferenceGraph - If non-empty, a serialized GraphDef representing a graph that must be analyzed at compile time to determine the shapes of the outputs.

key - A unique identifier for this region used to match up host transfers.

options - carries optional attribute values

Returns:

a new instance of XlaHostCompute

sendKey

public static XlaHostCompute.Options sendKey(String sendKey)

Sets the sendKey option.

Parameters:

sendKey - the sendKey option

Returns:

this Options instance.

recvKey

public static XlaHostCompute.Options recvKey(String recvKey)

Sets the recvKey option.

Parameters:

recvKey - the recvKey option

Returns:

this Options instance.

costEstimateNs

public static XlaHostCompute.Options costEstimateNs(Long costEstimateNs)

Sets the costEstimateNs option.

Parameters:

costEstimateNs - Estimated duration of the host computation in nanoseconds.

Returns:

this Options instance.

tpuCore

public static XlaHostCompute.Options tpuCore(Long tpuCore)

Sets the tpuCore option.

Parameters:

tpuCore - Default core to use for host to device transfers.

Returns:

this Options instance.

outputs

public List<Output<?>> outputs()

Gets outputs. A list of tensors that will be returned to the device.

Returns:

outputs.

iterator

public Iterator<Operand<TType>> iterator()
