Class BroadcastTo<T>

java.lang.Object

org.tensorflow.op.PrimitiveOp

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

Type Parameters:

T - data type for output() output

All Implemented Interfaces:

Op, Operand<T>

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

Broadcast an array for a compatible shape.

Broadcasting is the process of making arrays to have compatible shapes for arithmetic operations. Two shapes are compatible if for each dimension pair they are either equal or one of them is one. When trying to broadcast a Tensor to a shape, it starts with the trailing dimensions, and works its way forward.

For example,

 >>> x = tf.constant([1, 2, 3])
 >>> y = tf.broadcast_to(x, [3, 3])
 >>> sess.run(y)
 array([[1, 2, 3],
        [1, 2, 3],
        [1, 2, 3]], dtype=int32)
 

In the above example, the input Tensor with the shape of `[1, 3]` is broadcasted to output Tensor with shape of `[3, 3]`.

Method Detail

create

public static <T,U extends Number> BroadcastTo<T> create(Scope scope,
                                                         Operand<T> input,
                                                         Operand<U> shape)

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

Parameters:

scope - current graph scope

input - A Tensor to broadcast.

shape - An 1-D `int` Tensor. The shape of the desired output.

Returns:

a new instance of BroadcastTo

output

public Output<T> output()

A Tensor.

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>
