Answer 1

This sounds like a classic case of multiple Python versions on the same machine.

Try a

pip --version

as well as a

python -m pip --version

and a

python --version

my guess is that the associated versions of Python are different (note the pip version won't be the same as the Python version: pip --version on my machine gives: 'pip 22.3.1 from /opt/homebrew/lib/python3.10/site-packages/pip (python 3.10)'). This is often the case where the user has an installed version, and the system comes with a version too; Macs often have this problem, for example.

My thoughts are to try

python -m pip install numpy

which should use a version of pip associated with the Python version you are using. If you want to play more with multiple Python versions, I recommend using pyenv or conda, which will allow multiple versions to be installed simultaneously with a better-defined separation.
