Pyomo turn off presolve of cplex

I have the problem that i have a iterable model with mutable variable and when cplex find a Infeasible result using the presolve it does have any result to iter with lastone.

Does someone know have to turn off the cplex's presolve?

I'm using Cplex 12.10. And I havent found the way to sett it in that way. Thanks

Solution 
  • opt = SolverFactory("cplex")
opt.options['preprocessing presolve'] = 0

    Turns presolve off
