Description
"Python is a programming language that lets you work more quickly and integrate your systems more effectively." More details are at Python
Running Program
Please also see Python-Sapelo2 as that documentation applies to the teaching cluster as well.
To see all versions of Python installed on the cluster, use:
ml spider Python
For example:
Version 2.7.18
Installed in /apps/eb/Python/2.7.18-GCCcore-11.3.0
To use this version, please load the module with
ml Python/2.7.18-GCCcore-11.3.0
Version 3.12.3
Installed in /apps/eb/Python/3.12.3-GCCcore-13.3.0
To use this version, please load the module with
ml Python/3.12.3-GCCcore-13.3.0
Here is an example of a shell script, sub.sh, to run on the batch queue:
#!/bin/bash
#SBATCH --job-name=j_Python
#SBATCH --partition=batch
#SBATCH --mail-type=ALL
#SBATCH --mail-user=username@uga.edu
#SBATCH --ntasks=1
#SBATCH --mem=10gb
#SBATCH --time=08:00:00
#SBATCH --output=Python.%j.out
#SBATCH --error=Python.%j.err

python [options]
In the real submission script, at least all the above underlined values need to be reviewed or to be replaced by the proper values.
Please refer to Running_Jobs_on_the_teaching_cluster, Run X window Jobs and Run interactive Jobs for more details of running jobs at Teaching cluster.
Here is an example of job submission command:

ml Python/3.12.3-GCCcore-13.3.0
python -h
usage: python [option] ... [-c cmd | -m mod | file | -] [arg] ...
Options (and corresponding environment variables):
-b : issue warnings about converting bytes/bytearray to str and comparing
bytes/bytearray with str or bytes with int. (-bb: issue errors)
-B : don't write .pyc files on import; also PYTHONDONTWRITEBYTECODE=x
-c cmd : program passed in as string (terminates option list)
-d : turn on parser debugging output (for experts only, only works on
debug builds); also PYTHONDEBUG=x
-E : ignore PYTHON* environment variables (such as PYTHONPATH)
-h : print this help message and exit (also -? or --help)
-i : inspect interactively after running script; forces a prompt even
if stdin does not appear to be a terminal; also PYTHONINSPECT=x
-I : isolate Python from the user's environment (implies -E and -s)
-m mod : run library module as a script (terminates option list)
-O : remove assert and __debug__-dependent statements; add .opt-1 before
.pyc extension; also PYTHONOPTIMIZE=x
-OO : do -O changes and also discard docstrings; add .opt-2 before
.pyc extension
-P : don't prepend a potentially unsafe path to sys.path; also
PYTHONSAFEPATH
-q : don't print version and copyright messages on interactive startup
-s : don't add user site directory to sys.path; also PYTHONNOUSERSITE=x
-S : don't imply 'import site' on initialization
-u : force the stdout and stderr streams to be unbuffered;
this option has no effect on stdin; also PYTHONUNBUFFERED=x
-v : verbose (trace import statements); also PYTHONVERBOSE=x
can be supplied multiple times to increase verbosity
-V : print the Python version number and exit (also --version)
when given twice, print more information about the build
-W arg : warning control; arg is action:message:category:module:lineno
also PYTHONWARNINGS=arg
-x : skip first line of source, allowing use of non-Unix forms of #!cmd
-X opt : set implementation-specific option
--check-hash-based-pycs always|default|never:
control how Python invalidates hash-based .pyc files
--help-env: print help about Python environment variables and exit
--help-xoptions: print help about implementation-specific -X options and exit
--help-all: print complete help information and exit
Arguments:
file : program read from script file
- : program read from stdin (default; interactive mode if a tty)
arg ...: arguments passed to program in sys.argv[1:]
