Dear Developers,
I have been working on a piece of code development that need your sincere help (three code file attached here).

I use run_slurm.py to use python subprocess module to submit multiple jobs to slurm cluster by invoking a sbatch file with a for loop to reach the following target:

1) create some environmental variables for job_slurm.py to run simulations (values of these environmental variables will change for each job with the for loop)

2) invoke submit_slurm.sh to submit a sbatch job that will run job_slurm.py

3) each job_slurm.py will use python multiprocess.Pool to run parallized simulations on each ./mod_bart.sh exeutable file (will run for a few hours) on a single compute node in cluster using all cores of this compute node

I get the following error all the time, could you provide some insights on how our implementation is wrong to achieve the desired goal:

Exception in thread Thread-3:
