# 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]
```

Args:

Returns:

• ``` Output ``` : 1-D.
