Reporting a bug

• [x ] I have tried using the latest released version of Numba (most recent is
  visible in the release notes
  (https://numba.readthedocs.io/en/stable/release-notes-overview.html).
• I have included a self contained code sample to reproduce the problem.
  i.e. it's possible to run as 'python bug.py'.

/home/david/.cache/pypoetry/virtualenvs/gnssml-FCwMErw_-py3.10/lib/python3.10/site-packages/numba/np/ufunc/parallel.py:371: NumbaWarning: The TBB threading layer requires TBB version 2021 update 6 or later i.e., TBB_INTERFACE_VERSION >= 12060.

I had the same problem and it turned out because i installed tbb with pip which is non-standard location.
you should look for the correct location
in my case

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/:/usr/lib/:/usr/lib64/:/home/mabd/.local/lib/

solved the problem ; of course change mabd to your username

you can check by
numba -s|grep True
