dpnp.unique_all¶

dpnp.unique_all(x, /)[source]¶

Find the unique elements of an array, and counts, inverse, and indices.

For full documentation refer to numpy.unique_all.

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.
indicesdpnp.ndarray: The first occurring indices for each unique element.
inverse_indicesdpnp.ndarray: The indices from the set of unique elements that reconstruct x.
countsdpnp.ndarray: The corresponding counts for each unique element.
