Python environment error

1

Since the archer2 upgrade, I am getting an error to do with the python environment on archer2 in u-cu858:

I’ve tried adding the line #!/usr/bin/env python

at the top of the regrid_NEMO4.2_to_BIKE.py script.

I’ve also tried changing the pythonpath to PYTHONPATH=/work/y07/shared/utils/core/python/miniconda2/bin/python

which is where the archer2 helpdesk said python2 can be found after the software upgrade:

They said:

To support NCAS users, my colleague Andy Turner has created a virtual environment that contains python 2 in /work/y07/shared/utils/core/python/miniconda2/ even though HPE no longer supports python2.

If I activate the environment, I get access to both python2 and python3:

rapostol@ln02:~> source /work/y07/shared/utils/core/python/miniconda2/bin/activate
(base) rapostol@ln02:~> python --version
Python 2.7.18 :: Anaconda, Inc.
(base) rapostol@ln02:~> python2 --version
Python 2.7.18 :: Anaconda, Inc.
(base) rapostol@ln02:~> python3 --version
Python 3.6.15

I’m wondering how I can set the python environment to python2 in my rose suite - I tried putting the line source /work/y07/shared/utils/core/python/miniconda2/bin/activate in my .bash_profile on archer2 but this hasn’t made a difference.

The full error I’m getting is:

Lmod is automatically replacing “cce/15.0.0” with “gcc/11.2.0”.
