Hello,

I am using the python/gurobi interface to read in the mps file. But it gives me the error: gurobipy.GurobiError: Unknown parameter: 'GURO_PAR_PYTHON'

Does anybody have some idea what is the possible reason?

Thank you

Daniel Espinoza

Hi Gary,

Could you show your code (or a snippet of it) as well as the log?

Best

Daniel

Hi, Daniel,

Thank you for your help. I attach the mps file and the screenshot of error message. The command is under Gurobi interactive shell.

Hi Gary,

It seems that you are running a very old version of Gurobi (5.6.3) which is no longer supported. I would strongly recommend to upgrade to the latest version.

You can use this link for guidance: http://www.gurobi.com/documentation/7.0/quickstart_windows/software_installation_guid.html#section:Installation
