Example in PyROS docs doesn't use solver of the correct class

Closed by accident. Sorry - I was intending to edit my post!

Certainly. Here's the error: ``` --------------------------------------------------------------------------- ValueError Traceback (most recent call last) in 16 "objective_focus": pyros.ObjectiveType.worst_case, 17 "solve_master_globally": True, ---> 18 "load_solution":False 19 }) 20 # =========================================================================================== /usr/local/lib/python3.7/site-packages/pyomo/contrib/pyros/pyros.py in solve(self,...

Also, I do seem to have the "baron" solver installed, as shown by this output: ``` pyo.SolverFactory('baron') >>> ```

`pyo.SolverFactory('baron').available()` yields `False`!

How do I make `baron` available to pyomo? I tried giving it the path explicitly: ``` import pyomo import pyomo.environ as pe solvername = 'baron' solverpath_exe = '/baron-osx64/baron' solver =...

@michaelbynum What should I do to resolve this? And - how can I help the Pyomo/PyROS community? Thanks.

@jsiirola Thanks that was very helpful! Now, I'm able to get PyROS to attempt to solve the optimization problem. However, the solver exits with `ValueError: Cannot load a SolverResults object...

AFAIK I don't have a license, so I'm running it in "demo" mode.

Example in PyROS docs doesn't use solver of the correct class

Okay, gotcha. So, I can't solve this problem using the demo license. What are my other options for non-convex MINLP solvers? I have a robust optimization problem that I want...

One that can integrate with PyROS, yes.
