Class DiagPart<T>

java.lang.Object

org.tensorflow.op.PrimitiveOp

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

Type Parameters:

T - data type for diagonal() output

All Implemented Interfaces:

Op, Operand<T>

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

Returns the diagonal part of the tensor.

This operation returns a tensor with the `diagonal` part of the `input`. The `diagonal` part is computed as follows:

Assume `input` has dimensions `[D1,..., Dk, D1,..., Dk]`, then the output is a tensor of rank `k` with dimensions `[D1,..., Dk]` where:

`diagonal[i1,..., ik] = input[i1, ..., ik, i1,..., ik]`.

For example:

 # 'input' is [[1, 0, 0, 0]
               [0, 2, 0, 0]
               [0, 0, 3, 0]
               [0, 0, 0, 4]]
 
 tf.diag_part(input) ==> [1, 2, 3, 4]

Method Detail

create

public static <T> DiagPart<T> create(Scope scope,
                                     Operand<T> input)

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

Parameters:

scope - current graph scope

input - Rank k tensor where k is even and not zero.

Returns:

a new instance of DiagPart

diagonal

public Output<T> diagonal()

The extracted diagonal.

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>
