Class TensorArrayConcat<T>

java.lang.Object

org.tensorflow.op.PrimitiveOp

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

Type Parameters:

T - data type for value() output

All Implemented Interfaces:

Op

@Operator
public final class TensorArrayConcat<T>
extends PrimitiveOp

Concat the elements from the TensorArray into value `value`.

Takes `T` elements of shapes

   (n0 x d0 x d1 x ...), (n1 x d0 x d1 x ...), ..., (n(T-1) x d0 x d1 x ...)
   

and concatenates them into a Tensor of shape:

 (n0 + n1 + ... + n(T-1) x d0 x d1 x ...)

All elements must have the same shape (excepting the first dimension).

Method Detail

create

public static <T> TensorArrayConcat<T> create(Scope scope,
                                              Operand<?> handle,
                                              Operand<Float> flowIn,
                                              Class<T> dtype,
                                              TensorArrayConcat.Options... options)

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

Parameters:

scope - current graph scope

handle - The handle to a TensorArray.

flowIn - A float scalar that enforces proper chaining of operations.

dtype - The type of the elem that is returned.

options - carries optional attributes values

Returns:

a new instance of TensorArrayConcat

elementShapeExcept0

public static TensorArrayConcat.Options elementShapeExcept0(Shape elementShapeExcept0)

Parameters:

elementShapeExcept0 - The expected shape of an element, if known, excluding the first dimension. Used to validate the shapes of TensorArray elements. If this shape is not fully specified, concatenating zero-size TensorArrays is an error.

value

public Output<T> value()

All of the elements in the TensorArray, concatenated along the first axis.

lengths

public Output<Long> lengths()

A vector of the row sizes of the original T elements in the value output. In the example above, this would be the values: `(n1, n2, ..., n(T-1))`.
