How to use the ruptures.utils.admissible_filter function in ruptures

def single_bkp(self, start, end):
        """Return the optimal breakpoint of [start:end] (if it exists)."""
        filtre = admissible_filter(start, end, self.jump, self.min_size)

        subsignal = self.signal[
            start:end] - self.signal[start:end].mean(axis=0)
        objective = np.sum(subsignal.cumsum(axis=0)**2, axis=1)
        sub_sampling = ((ind, val) for ind, val in enumerate(objective, start=start + 1)
                        if filtre(ind))
