  • Make sure to select " :white_check_mark: Add Anaconda3 to my PATH environment variable " and " :white_check_mark: Register Anaconda3 as my default Python 3.8 "

2. Install a Python Solver

  • Gurobi can be installed as a solver for the Python programming language with the installation of Gurobipy. Other solvers can also be used.

  • Download the Gurobi optimizer for your system from the Gurobi Academia page.

  • Run the installation wizard for Gurobi and select default location installation.

  • Make sure you are connected to an academic network or vpn and request an Academic License from Gurobi, a code in the form grbgetkey xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx should be generated

  • Open Gurobi Interactive Shell and a license code should be requested corresponding the the code after grbgetkey, being xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx. Interactive Shell will close automatically.

  • Gurobipy now can be installed by opening the Anaconda Prompt and adding the Gurobi channel to install Gurobipy using the following commands.

(base) C:\Users\YourUser>conda config --add channels https://conda.anaconda.org

(base) C:\Users\YourUser>conda install -c conda-forge pyomo

4. Done
