Gurobi
The Gurobi Optimizer is a state-of-the-art solver for mathematical programming. The solvers in the Gurobi Optimizer were designed from the ground up to exploit modern architectures and multicore processors, using the most advanced implementations of the latest algorithms.
Available Versions
To find the available versions and learn how to load them, run:
module spider gurobi
The output of the command shows the available Gurobi
module versions. To load the most recent version of Gurobi
, at the terminal window prompt run:
module load gurobi
For detailed information about a particular Gurobi
module, including how to load the module, run the module spider command with the module’s full version label. For example:
module spider gurobi/10.0.1
| Module | Version |
Module Load Command |
|---|
| gurobi | 10.0.1 |
module load gurobi/10.0.1
|
| gurobi | 11.0.0 |
module load gurobi/11.0.0

License and Permission
We have an academic site license that allows UVA faculty, staff, and students to use Gurobi on the HPC system. The license is restricted to academic use and all use for commercial purposes is forbidden.
Please submit a ticket if you are UVA faculty/staff/student and need access to the software.
Using Gurobi
There are several ways to use Gurobi. First load the module.
Gurobi command prompt
Run:
gurobi.sh
Python
To import gurobipy as a Python module, you can use either Gurobi’s own python3.7 executable or a different python. gurobi/10.0.1 uses python3.7 and gurobi/11.0.0 uses python3.11.
Gurobi Python
Please replace python with python3.7 or python3.11 in your Slurm scripts. However, note that Gurobi does not provide pip. If you need additional Python packages please use a non-Gurobi Python (e.g. via module load miniforge). See next section.
Non-Gurobi Python
Gurobi/10.0.1 supports Python versions 2.7, 3.6 - 3.9. Please follow the instructions in the module load message.
To check the version of your python, run python -V.
If you followed these instructions and still have trouble importing gurobipy in your Python script, please use the Gurobi Python python3.7.
Julia
The GUROBI_HOME environment variable is already defined. Load the julia module and run:
import Pkg
Pkg.add("Gurobi")
Pkg.build("Gurobi")
