Class Placeholder<T>

java.lang.Object

org.tensorflow.op.PrimitiveOp

org.tensorflow.op.core.Placeholder<T>

Type Parameters:

T - data type for output() output

All Implemented Interfaces:

Op, Operand<T>

@Operator
public final class Placeholder<T>
extends PrimitiveOp
implements Operand<T>

A placeholder op for a value that will be fed into the computation.

N.B. This operation will fail with an error if it is executed. It is intended as a way to represent a value that will always be fed, and to provide attrs that enable the fed value to be checked at runtime.

Method Detail

create

public static <T> Placeholder<T> create(Scope scope,
                                        Class<T> dtype,
                                        Placeholder.Options... options)

Factory method to create a class to wrap a new Placeholder operation to the graph.

Parameters:

scope - current graph scope

dtype - The type of elements in the tensor.

options - carries optional attributes values

Returns:

a new instance of Placeholder

shape

public static Placeholder.Options shape(Shape shape)

Parameters:

shape - (Optional) The shape of the tensor. If the shape has 0 dimensions, the shape is unconstrained.

output

public Output<T> output()

A placeholder tensor that must be replaced using the feed mechanism.

asOutput

public Output<T> asOutput()

Description copied from interface: Operand

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.

Specified by:

asOutput in interface Operand<T>
