Gurobi: Difference between revisions

  python3.11

As mentioned near the bottom of this official document [[support.gurobi.com/hc/en-us/articles/360044290292-How-do-I-install-Gurobi-for-Python|How-do-I-install-Gurobi-for-Python]] the previously recommended method for installing Gurobi for Python with <code>setup.py</code> has been deprecated to be only usable with Gurobi 10 versions (and older).  Therefore a new section has been added below which shows howto simultaneously download a compatible binary wheel from [[pypi.org/project/gurobipy|pypi.org]] and simultaneously convert it into a format usable with a newly recommended command to install Gurobi for Python with Gurobi 11 versions (and newer).

Python scripts, such as the examples provided with the gurobi module can now be run (within the virtual environment) using python :

{{Commands|prompt=(env_gurobi) [name@server ~] $

| python $EBROOTGUROBI/examples/python/matrix1.py

Likewise custom python scripts such as the following can be run as jobs in the queue by writing slurm scripts that load your virtual environment.

{{Commands|prompt=[name@server ~] $

| cat my_gurobi_script.py

}}

Submit your script to the queue by running <code>sbatch my_slurm_script.sh</code> as per usual :

#SBATCH --mem=4000M            # specify total MB memory

module load StdEnv/2023

module load gurobi/11.0.1

# module load scipy-stack      # uncomment if needed

echo "Threads ${SLURM_CPUS_ON_NODE:-1}" > gurobi.env

source ~/env_gurobi/bin/activate

python my_gurobi_script.py
