Finding out reason of Pyomo model infeasibility

by

Many solvers (including IPOPT) will hand you back the value of the variables at solver termination, even if the problem was found infeasible. At that point, you do have some options.

There is contributed code in pyomo.util.infeasible that might help you out. https://github.com/Pyomo/pyomo/blob/master/pyomo/util/infeasible.py

Usage:

from pyomo.util.infeasible import log_infeasible_constraints
...
SolverFactory('your_solver').solve(model)
...
log_infeasible_constraints(model)
