TypeError: Unexpected keyword argument {'n_jobs': 96}

From https://docs.scipy.org/doc/scipy/reference/generated/scipy.spatial.cKDTree.query.html

The “n_jobs” argument was renamed “workers”. The old name “n_jobs” was deprecated in SciPy 1.6.0 and was removed in SciPy 1.9.0.

Yeah, just hit this as well. Temporarily switching to scipy=1.8.1, which I can confirm works fine, but this should be an easy quick fix and pull request if someone has a moment.
