python - Is it possible to import multi-set parameters via pyodbc in a Pyomo Abstract Model? -


has been successful in loading multiset parameter in pyomo using pyodbc?

example:

    load "driver={postgresql};database=db;server=srv;user=user;" using='pyodbc' query="select a, b, c tbl": [a, b] c;

the corresponding entry in model 

    model.c = param(model.a,model.b)

loading one-dimensional sets , parameters work. query above results in 'abstractmodel' object has no attribute 'c' error.

i solved issue converting abstract model concrete model , importing data via psycopg2 connections.
