Usage

An example on how to run a python script called my_script.py taking 2 arguments var1 and var2 as inputs, and using the base environement is provided below. A complete example with outputs can be found here.

from sbatchpy import run

config = {
    "mem": "1gb",
    "time": "00:01:00",
    "account": "myaccount",
    "cpus-per-task": "5",
    "partition": "shared",
    "ntasks-per-node": "1",
    "nodes": "1",
}

for var1, var2 in zip([1, 2, 3], ["A", "B", "C"]):

    config["job-name"] = f"myjob_{var1}var1_{var2}var2.sh"
    config["output"] = f"out/myjob_{var1}var1_{var2}var2.out"
    run(
        config,
        code=f"source activate base \n python my_script.py {var1} {var2}",
    )

By default, sbatchpy will check that config["output"]'s directory folder exists. If it doesn't, you will be notified and the job will not run.

Additionally, each sbatch submission script is saved inside the f"{os.getcwd()}/.job" folder. Another saving folder can be chosen by passing job_directory=my_saving_directory_path to the run function which is responsible of creating the submission script and running it using sbatch job_directory/config["job-name"].
