Can you pass command line values to pyomo, like sys.argv for python scripts?

Question

In regular python scripts, you can pass command line parameters to python scripts with the sys.argv. For example, a python script named parameter_pass.py that contains:

# simple python example

import sys

val = sys.argv[1]

print(val)

Called with python parameter_pass.py hi prints 'hi' to the console. But the same does not work for a pyomo solve command line call as far as I can tell. Is there a way to pass command line parameters beyond solver options to a pyomo model?

Answer 1

I don't know of an easy way to do this with the pyomo solve command line interface but you can easily do this by using the scripting interface to Pyomo. Just write a Python script that builds a concrete Pyomo model and calls a solver and you can run it using python mymodel.py. Then you can add anything else you want to the Python script including passing in command line values.
