Gurobi Environment handling

[torressa]

What language and solver does this apply to?
Every language except C++ (this already exists).

Describe the problem you are trying to solve.

I would like to be able to pass a Gurobi environment as input.
In C++ this already exists via

or-tools/ortools/linear_solver/gurobi_proto_solver.h

Lines 35 to 36 in 82750ac

	absl::StatusOr<MPSolutionResponse> GurobiSolveProto(
	const MPModelRequest& request, GRBenv* gurobi_env = nullptr);

All other APIs cannot take a user-defined environment (Gurobi has an Env construct for all Python, Java, .NET).
Please correct me if this is already possible.

Describe the solution you'd like

To be able to pass an environment for example

import gurobipy as gp

with gp.Env() as myenv:
  solver = pywraplp.Solver.CreateSolver("GUROBI", env=myenv)

This is not possible.

Currently it's not possible - but what would need to change to make this possible? @lperron Do you have specific concerns around implementing this possibility for languages like Python?

[lperron]

Very complex. I do not want to depend on gurobipy, and the code is not structured this way. The only solution is to pass the structure that holds the isv key from python to c++. Le mar. 31 janv. 2023, 21:39, Ronald van der Velden < ***@***.***> a écrit :
