Have have managed to install numpy and Mr Ink is working fine now. Thanks again.
For anyone else with this problem, I followed these instructions -
Open an elevated command prompt.
(e.g. search Windows for CMD and right click, run as admin)
then enter
cd C:\Program Files\Autodesk\Maya2023\bin
that should stick you inside that folder. Then type
mayapy -m pip install numpy
and that should install the latest version of numpy
