I am trying to read a mps file using the following code:
m_internal = MathProgBase.LinearQuadraticModel(GurobiSolver())
c = MathProgBase.getobj(m_internal)
A = MathProgBase.getconstrmatrix(m_internal)
This code was working a while ago, however now when I call the function readLP() I have the following error
" UndefVarError: GurobiSolver not defined"
I have gurobi installed and its working properly since I am using it in some other part of the code without any problem…
