Historical replace_landsurface.py python interpreter

[jo-basevi]

The replace_landsurface.py scripts currently uses a python interpreter in hh5

access-esm1.5-configs/scripts/update_landuse.py

Line 1 in def5a8a

#!/g/data/hh5/public/apps/nci_scripts/python-analysis3

If changed to #!/usr/bin/env python3, it currently runs into errors when run as a user-script on payu as it defaults to /bin/python3 - payu-org/payu#490

A temporary workaround until the above in fixed in payu, could be to use payu/1.1.4's python interpreter which has access to mule and xarray, so it'll be #!/g/data/vk83/apps/payu/1.1.4/bin/python3

Another workaround is to use the existing environment variable $PAYU_PATH which is the directory that contains the payu install. So call $PAYU_PATH/python3 scripts/update_landuse.py in scripts/update_landuse_driver.sh
