Cvxopt.glpk is not installed

Hello,

while running my project i got the following error:


File "C:\Python27\solve_problem.py", line 112, in init_problem
(duals,duals_eq,obj) = solve_relaxed(f,A,b,Aeq,beq)
File "C:\Python27\solve_problem.py", line 83, in solve_relaxed
sol = solvers.lp(matrix(f), matrix(A), matrix(B),matrix(Aeq), matrix(beq), s
olver = 'glpk')
File "C:\Python27\lib\site-packages\cvxopt\coneprog.py", line 2822, in lp
except ImportError: raise ValueError("invalid option "\
ValueError: invalid option (solver = 'glpk'): cvxopt.glpk is not installed

Note that i already installed cvxopt module correctly.

Any ideas?

Thank you.

Maybe cvxopt is installed correctly, but was not built with glpk included.

What is the problem you're trying to solve?

You can probably do it with scipy which has been around quite a while and works pretty well.

[edit=based on Lux Perpetua's question in following post] scipy does not, as far as I can tell, have any routines designed for linear programming. (other than unconstrained simplex method) I did not investigate glpk.[/edit]

Does scipy do linear programming, though?

moushakes12: why are you passing the "solver='glpk'" option to solvers.lp? Is there some reason you can't use cvxopt's default solver? If you must use the GLPK backend, you have to install GLPK separately.
