Class Cumprod<T>

java.lang.Object

org.tensorflow.op.PrimitiveOp

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

Type Parameters:

T - data type for out() output

All Implemented Interfaces:

Op, Operand<T>

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

Compute the cumulative product of the tensor `x` along `axis`.

By default, this op performs an inclusive cumprod, which means that the first element of the input is identical to the first element of the output:

 tf.cumprod([a, b, c])  # => [a, a * b, a * b * c]
 

By setting the `exclusive` kwarg to `True`, an exclusive cumprod is performed instead:

 tf.cumprod([a, b, c], exclusive=True)  # => [1, a, a * b]
 

By setting the `reverse` kwarg to `True`, the cumprod is performed in the opposite direction:

 tf.cumprod([a, b, c], reverse=True)  # => [a * b * c, b * c, c]
 

This is more efficient than using separate `tf.reverse` ops.

The `reverse` and `exclusive` kwargs can also be combined:

 tf.cumprod([a, b, c], exclusive=True, reverse=True)  # => [b * c, c, 1]

Method Detail

create

public static <T,U extends Number> Cumprod<T> create(Scope scope,
                                                     Operand<T> x,
                                                     Operand<U> axis,
                                                     Cumprod.Options... options)

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

Parameters:

scope - current graph scope

x - A `Tensor`. Must be one of the following types: `float32`, `float64`, `int64`, `int32`, `uint8`, `uint16`, `int16`, `int8`, `complex64`, `complex128`, `qint8`, `quint8`, `qint32`, `half`.

axis - A `Tensor` of type `int32` (default: 0). Must be in the range `[-rank(x), rank(x))`.

options - carries optional attributes values

Returns:

a new instance of Cumprod

exclusive

public static Cumprod.Options exclusive(Boolean exclusive)

Parameters:

exclusive - If `True`, perform exclusive cumprod.

reverse

public static Cumprod.Options reverse(Boolean reverse)

Parameters:

reverse - A `bool` (default: False).

out

public Output<T> out()

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>
