Return an array of indices indicating missing labels.

Parameters
yarray-like, shape (n_samples) or (n_samples, n_outputs)

Class labels to be checked w.r.t. to present labels.

missing_labelnumber | str | None | np.nan, optional (default=np.nan)

Symbol to represent a missing label.

Returns
unlbld_indicesnumpy.ndarray, shape (n_samples) or (n_samples, 2)

Index array of missing labels. If y is a 2D-array, the indices have shape (n_samples, 2), otherwise it has the shape `(n_samples).
