Description

I have installed the version v7.0.7 on a new laptop, and the time for sorting equations before simulation is very long (I stopped after 8 min) whereas on another laptop, using v7.0.4, it takes some seconds. it seems that some others colleagues experimented the same issue with the version 7.0.5.
How to install version 7.0.4 to ensure that is not a problem with the laptop but with the Iode version.
I copy paste the code (the number of equations is 266 000)

simulparams = io.Simulation(convergence_threshold = 0.0001, relax = 0.9, max_nb_iterations = 25000,
sort_algorithm = 'CONNEX', initialization_method = 'TM1', debug = False,
nb_passes = 5, debug_newton = False)

simul_str = "2020Y1"
simul_end = "2050Y1"
simulparams.model_simulate(simul_str, simul_end)
