Hello, i have problems with installing the Gurobi Optimizer. 

 

I downloaded the optimizer from the official website and installed it on my pc. After i get the academic license code i paste it in the promt of my pc. Once the code is saved, i enter following code: 

conda config --add channels http://conda.anaconda.org/gurobia

Until here everything works fine. Now i want to install gurobi with following code: 

conda install gurobi

If i use the newest versions of anaconda and gurobi, my pc tells me the following:

When i use older versions of anaconda or gurobi the following error pops up:

Can somebody help me please?

  Hi Luca,

  The Gurobi package is not available on Anaconda for all Python versions: Files :: Anaconda.org

  Specifically, Gurobi for Python 3.9 is not available. You can either use a different Python version in your Anaconda environment, e.g., Python 3.8 or install the Gurobi Python package via pip

  python -m pip install gurobipy

  or directly from your installation folder:

  python setup.py install

  Cheers,
  Matthias
