How to call Gurobi solver?

Specific Domains Optimization (Mathematical)

When I called Gurobi (v1.1.0) with the following code,

m_cvx = Model(optimizer_with_attributes(Gurobi.Optimizer,GRB_ENV,“OutputFlag”=>0))

it fails with methoderror.

MethodError: no method matching optimizer_with_attributes(::Type{Gurobi.Optimizer}, ::Gurobi.Env, ::Pair{String, Int64})

Closest candidates are:
  optimizer_with_attributes(::Any, !Matched::Pair...)
   @ JuMP C:\Users\MNRG\.julia\packages\JuMP\D44Aq\src\optimizer_interface.jl:47

Stacktrace:
 [1] cvxrs(network_data::Dict{String, Any}, option::String, target_network_data::Nothing)
   @ Main C:\Users\MNRG\Desktop\PowerFlowCVXRS-master\src\main.jl:405

How should I call Gurobi solver?

Hi @Kaiming_Zhang

See jump-dev/Gurobi.jl · JuMP

You need

model = Model(() -> Gurobi.Optimizer(GRB_ENV))
set_silent(model)
