julia> using JuMP, Ipopt
[ Info: Precompiling Ipopt [b6b21f68-93f8-5de0-b562-5493be1d77c9]
julia> direct_model(Ipopt.Optimizer())
Error showing value of type Model:
ERROR: MathOptInterface.GetAttributeNotAllowed{MathOptInterface.Name}: Getting attribute MathOptInterface.Name() cannot be performed: Ipopt.Optimizer does not support getting the attribute MathOptInterface.Name(). You may want to use a `CachingOptimizer` in `AUTOMATIC` mode or you may need to call `reset_optimizer` before doing this operation if the `CachingOptimizer` is in `MANUAL` mode.
