Why are all my models named "unknown rosepy problem.mps?"

"Unknown rosepy problem" is the default name given to models uploaded through rosepy when no explicit name is set in Pyomo. This happens when you create your model like model = pyo.ConcreteModel().

How to name your models

To set a custom name, pass the name parameter when initializing the model. An example is shown below.

import pyomo.environ as pyo
model = pyo.ConcreteModel(name='My optimization problem')

Now, when uploaded to Rose, your model will carry the name "My optimization problem.mps" instead of the default name.
