dpnp.unique_inverse¶

dpnp.unique_inverse(x, /)[source]¶

Find the unique elements of x and indices to reconstruct x.

For full documentation refer to numpy.unique_inverse.

Parameters:

x{dpnp.ndarray, usm_ndarray}: Input array. It will be flattened if it is not already 1-D.

Returns:

A namedtuple with the following attributes:
valuesdpnp.ndarray: The unique elements of an input array.
inverse_indicesdpnp.ndarray: The indices from the set of unique elements that reconstruct x.

Examples

>>> import dpnp as np
>>> x = np.array([1, 1, 2])
>>> uniq = np.unique_inverse(x)
>>> uniq.values
array([1, 2])
>>> uniq.inverse_indices
array([0, 0, 1])
