tensorflow::ops::Unique

#include <array_ops.h>

Finds unique elements in a 1-D tensor.

Summary

This operation returns a tensor y containing all of the unique elements of x sorted in the same order that they occur in x. This operation also returns a tensor idx the same size as x that contains the index of each value of x in the unique output y. In other words:

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

For example:

``` tensor 'x' is [1, 1, 2, 4, 4, 4, 7, 8, 8]

y, idx = unique(x) y ==> [1, 2, 4, 7, 8] idx ==> [0, 0, 1, 2, 2, 2, 3, 4, 4] ```

Arguments:

• scope: A Scope object
• x: 1-D.

Returns:

• Output y: 1-D.
• Output idx: 1-D.
