enquiry about libsumo importError #1

I create a virtual environment of 3.9 and install the packages in the requirement. When I run simulate_town_cosim.py, it says:

Traceback (most recent call last): File "d:\research\Macro_and_micro_co-simulation\EGO-centric-SUMO-main\EGO-centric-SUMO-main\simulate_town_cosim.py", line 5, in from libsumo_parallel import * File "d:\research\Macro_and_micro_co-simulation\EGO-centric-SUMO-main\EGO-centric-SUMO-main\libsumo_parallel.py", line 8, in import libsumo File "E:\SUMO\tools\libsumo__init__.py", line 30, in from .libsumo import vehicle, simulation, person, trafficlight # noqa File "E:\SUMO\tools\libsumo\libsumo.py", line 13, in from . import _libsumo ImportError: DLL load failed while importing _libsumo: The specified module could not be found.

How can this be fixed? Thank you.

Dear Xingyi He,

Depending on your operating system, you might have to take some additional steps to make it work. Please see https://sumo.dlr.de/docs/Libsumo.html#building_and_installing_it
