I think the upgrade of Numpy had been a mistake.  All the Python
scientific stack has to be upgraded in one go.  From my understanding,
it is the same issue as Haskell and LTS, for instance.  As Lars said,
try to have several versions would probably lead to a mess with weird
behaviours difficult to debug; from my understanding.

The best is to downgrades python-numpy to 1.20 (potentially 1.20.3
released on May 2021, that’s not that old :-)) and wait python-numba
works with Numpy 1.21.  IMHO.
