Rebuilding new Pyn descent(numba 0.60, python 3.12) object from existing object(python 3.9))

I have a pynn descent object saved using Python 3.9 with Numba 0.56. Now, when I try to load it in Python 3.12, it fails due to the Numba version change, and I no longer have the original data used to create the object.

To resolve this, I plan to create a new object in Python 3.12 by loading the _raw_data parameter in the order specified by np.argsort(_vertex_order). Then, I'll save this new object in Python 3.9 and recreate it in Python 3.12.

Would it work? Any unknowns that i need to be careful of?

The issue names a saved pynn descent object and its _raw_data and _vertex_order parameters, but no files, tests, or entry points. Start by examining how those parameters are serialized and restored, then verify whether the proposed ordering survives the Python and Numba version change. Done would require a confirmed migration path or a reproducible compatibility fix.
