Error running shapemer from RADIUS

[rrw1007]

I am running the 'getting_started.ipynb' notebook.

The following lines of code: invariants, _ = get_invariants_for_structures(X_names, n_threads=4, split_infos=[SplitInfo(SplitType.RADIUS, 5)], moment_types=["O_3", "O_4", "O_5", "F"])

give the error below:

AttributeError: 'C KDTree' object has no attribute 'search_center_radius'
