UnravelIndex

public final class UnravelIndex

Converts an array of flat indices into a tuple of coordinate arrays.

Example: 

y = tf.unravel_index(indices=[2, 5, 7], dims=[3, 3])
 # 'dims' represent a hypothetical (3, 3) tensor of indices:
 # [[0, 1, *2*],
 #  [3, 4, *5*],
 #  [6, *7*, 8]]
 # For each entry from 'indices', this operation returns
 # its coordinates (marked with '*'), such as
 # 2 ==> (0, 2)
 # 5 ==> (1, 2)
 # 7 ==> (2, 1)
 y ==> [[0, 1, 2], [2, 2, 1]]

Constants

public static final String OP_NAME

The name of this op, as known by TensorFlow core engine

Constant Value: "UnravelIndex"

Public Methods

public Output<T> asOutput ()

Returns the symbolic handle of the 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.

public static UnravelIndex<T> create (Scope scope, Operand<T> indices, Operand<T> dims)

Factory method to create a class wrapping a new UnravelIndex operation.

Parameters
scope current scope
indices An 0-D or 1-D `int` Tensor whose elements are indices into the flattened version of an array of dimensions dims.
dims An 1-D `int` Tensor. The shape of the array to use for unraveling indices.
Returns
  • a new instance of UnravelIndex

public Output<T> output ()

An 2-D (or 1-D if indices is 0-D) tensor where each row has the same shape as the indices array.
