Can't dump JuMP model #178

Open facq opened 7 years ago

facq commented 7 years ago

Hi !

very useful module :)

but i got a problem trying to save a "Model" data structure from JuMP package.

i use julia 0.6.0

here is my test script : 

> using JuMP
> using Clp
> #using CPLEX
> 
> using JLD
> 
> m = Model(solver = ClpSolver())
> #m = Model(solver = CplexSolver())
> @variable(m, 0 <= x <= 2 )
> @variable(m, 0 <= y <= 30 )
> 
> @objective(m, Max, 5x + 3*y )
> @constraint(m, 1x + 5y <= 3.0 )
> 
> print(m)
> 
> save("/tmp/dump.jld", "model", m)
> 
> status = solve(m)
> 
> println("Objective value: ", getobjectivevalue(m))
> println("x = ", getvalue(x))
> println("y = ", getvalue(y))
> 
> ##########
> 
> n= load("/tmp/dump.jld", "model")
> 
> status = solve(n)
> 
> println("Objective value: ", getobjectivevalue(n))
> println("x = ", getvalue(x))
> println("y = ", getvalue(y))
>

and here what i get : 

Max 5 x + 3 y
Subject to
 x + 5 y ≤ 3
 0 ≤ x ≤ 2
 0 ≤ y ≤ 30
