	Numpy and Scipy (and pretty much anything one installs with pip) are
3rd-party packages, handled by other developers. As such, they may not be
compatible with newer releases of Python -- or won't be compatible until
some months later.

	FYI: my Python 3.10 install uses numpy 1.24.2, and scipy 1.10.1 -- the
versions you have installed are quite old.

	I had tried installing Python 3.11 a few weeks ago, but pip was unable
to install numpy for that version. Numpy github page implies that 1.24.2
supports Python 3.8 to 3.11; it appears to have been released Feb 5 -- but
(I'm on Windows) pip binaries may not have been available -- don't know
about your OS; it may build from source files. I also don't know where
Linux would store the packages. Windows stores them in a subdirectory of
the installed Python version; as a result, different Python installs have
their own packages and you'd have to run pip install using the pip from the
new Python version to add the compatible packages.
