    Recreates and caches internal data structures from the clustering stage.

    Parameters
    ----------

    data : array (n_samples, n_features)
        The original data set that was clustered.

    labels : array (n_samples)
        The cluster labels for every point in the data set.

    condensed_tree : array (n_points + n_merges, 4)
        The condensed tree produced during clustering, used to extract outliers.

    min_samples : int
        The min_samples value used in clustering.

    tree_type : string, optional
        Which type of space tree to use for core distance computation.
        One of:
            * ``kdtree``
            * ``balltree``

    metric : string, optional
        The metric used to determine distance for the clustering.
        This is the metric that will be used for the space tree to determine
        core distances etc.

    **kwargs :
        Any further arguments to the metric.

    Attributes
    ----------

    all_finite : bool
        Whether the data set contains any infinite or NaN values.

    finite_index : array (n_samples)
        The indices of the finite data points in the original data set.

    internal_to_raw : dict
        A mapping from the finite data set indices to the original data set.

    tree : KDTree or BallTree
        A space partitioning tree that can be queried for nearest neighbors if
        the metric is supported by a KDTree or BallTree.

    neighbors : array (n_samples, min_samples)
        The nearest neighbor for every non-noise point in the original data set.

    core_distances : array (n_samples)
        The core distance for every non-noise point in the original data set.

    dist_metric : callable
        Accelerated distance metric function.
