I cannot use the commands with_optimizer() and getobjectivevalue() with JuMP, Gurobi

[odow]

@medardo

m = Model(with_optimizer(Clp.Optimizer, LogLevel = 0))

The bad news is that we changed this syntax a couple of years ago. The good news is that now JuMP is 1.0, the syntax below won’t change in future:

m = Model(optimizer_with_attributes(Clp.Optimizer, "LogLevel" => 0))
