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). | 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).
