numpy.unique_values#

numpy.unique_values(x)[source]#

Returns the unique elements of an input array x.

This function is an Array API compatible alternative to:

np.unique(x, equal_nan=False, sorted=False)

Changed in version 2.3: The algorithm was changed to a faster one that does not rely on sorting, and hence the results are no longer implicitly sorted.

Parameters:

xarray_like: Input array. It will be flattened if it is not already 1-D.

Returns:

outndarray: The unique elements of an input array.

Examples

>>> import numpy as np
>>> np.unique_values([1, 1, 2])
array([1, 2])  # may vary
