I used the following code for multiprocessing, but it gives different results in each run. Am I doing something wrong?

import multiprocessing as mp
import gurobipy as gp

def solve_model(input_data):
    with gp.Env() as env, gp.Model(env=env) as model:
        #read model from LP file
        model.optimize()
        # retrieve data from model

if __name__ == '__main__':
    with mp.Pool() as pool:
        pool.map(solve_model, [input_data1, input_data2, input_data3]

  Hi Sanjeev,

  Could you please try posting a minimal reproducible example (MRE)?

  Best regards,
