tensorflow::ops::InvertPermutation

#include <array_ops.h>

Computes the inverse permutation of a tensor.

Summary

This operation computes the inverse of an index permutation. It takes a 1-D integer tensor x, which represents the indices of a zero-based array, and swaps each value with its index position. In other words, for an output tensor y and an input tensor x, this operation computes the following:

y[x[i]] = i for i in [0, 1, ..., len(x) - 1]

The values must include 0. There can be no duplicate values or negative values.

For example:

``

tensor

x` is [3, 4, 0, 2, 1] invert_permutation(x) ==> [2, 4, 3, 0, 1] ```

Arguments:

  • scope: A Scope object
  • x: 1-D.

Returns:
