@wghuneke EDIT: I’ve just had a poke around in access/modules - there’s an xp65 version in there already:
$ ll /g/data/access/modules/pythonlib/um2netcdf4/
total 12
-rw-r-----+ 1 mrd599 access.admin 525 Mar 10 2022 2.0
-rw-r-----+ 1 mrd599 access.admin 525 Jan 16 2023 2.1
-rw-r-----+ 1 mrd599 access.admin 735 Aug 15 08:58 xp65
Can you try explicitly loading it and see what happens (unless someone from NRI jumps in to say we shouldn’t be doing that)?:
module load pythonlib/um2netcdf4/xp65
