LSF example of a serial python job, with a virtual environment

python_job.sh

#!/bin/bash
#
#BSUB -o pyjob.%J.out
#BSUB -e pyjob.%J.err
#BSUB -n 1

# do stuff
source ~/venv/bin/activate
python -c "import pyica; import sys; print(sys.version); from numpy.random import randn; x = randn(); print '%f' %x"

# Notes:
# -%J adds the job number to the error/output files
# -this job is purely serial, so -n is ignored anyway
# -submit with bsub < ./python_job.sh
# -source command makes sure to activate the virtual environment
