retrieving Solution status in python

Hi,

I am solving multiple models in a loop, and sometimes some of them might not have a feasible solution and python yields the error:

RuntimeError: The model is unsolved or no solution is obtained.

I want to avoid stopping the loop by this error, and instead retrieve the status variable so that I can do some changes and my loop (next models) keeps running.

  Hi Amal,

  generally, the model status in Python can be retrieved by calling:

  model.status

  An overview of the model statuses can be seen here.

  Hope this helps.

  Best regards
  Jonasz
