Background
As recently as two months ago, I've had a working python script which i used regularly to combine netcdf4 weather files together.
However, ever since I recently updated my laptop, and reinstalled python (3.7 as per I.T. policy) and the latest python libraries, and the script has stopped working, it appears something has been deprecated, this has caused my code to stop working.
Problem
I am getting the error message: AttributeError: 'EntryPoints' object has no attribute 'get'
What I've tried
I've referred to these other posts on SO (link, link). From that I can see the issue has arisen from importlib-metadata (v5.0.0. +), Which comes as part of the standard python install (including 3.7) (I have importlib-metadata-6.6.0 on my machine)
I tried downgrading to an older version (importlib-metadata 4.0.0), but that resulted in a different problem.
I also asked I.T. to update my python to higher version (3.9, 3.10, etc). But apparently that's an entire process which could take ages to do.
Help Requested
Anyone know how I can resolve this issue.
