The result is a view of y, and the metadata (unique) is not attached to y. IMPORTANT: The output of this function should NEVER be returned in functions. This is to avoid this pattern: .. code:: python y = np.array([1, 2, 3]) y = attach_unique(y) y[1] = -1 # now np.unique(y) will be different from cached_unique(y) Parameters ---------- *ys : sequence of array-like Input data arrays. return_tuple : bool, default=False If True, always return a tuple even if there is only one array.
