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

  • values (dpnp.ndarray) -- The unique elements of an input array.

  • indices (dpnp.ndarray) -- The first occurring indices for each unique element.

  • inverse_indices (dpnp.ndarray) -- The indices from the set of unique elements that reconstruct x.

  • counts (dpnp.ndarray) -- The corresponding counts for each unique element.
