[sumo-user] Connection error [WinError 10061]

["Zimmermann, Liesa" <liesa.zimmermann@xxxxxxxxxxxx>]

Hello,

I am trying to interface with SUMO from Python, following the steps in the documentation:

https://sumo.dlr.de/docs/TraCI/Interfacing_TraCI_from_Python.html

 

Sumo opens, without opening the sumocfg-file and I get the error:

 

Retrying in 1 seconds

Could not connect to TraCI server at localhost:51329 [WinError 10061] No connection could be made because the target machine actively refused it

 

I checked the firewall as suggested in the mailing list (27 Aug 2017 on a similar issue) and turned it off, but it did not work. Running as admin changed nothing either.

I’m using SUMO 1.7 on Windows 10.

 

The script I used (from the documentation):

import os

import sys

sys.path.append("C:/Program Files (x86)/Eclipse/SUMO 1.7/tools")

import traci

 

sumoBinary = "C:/Program Files (x86)/Eclipse/SUMO 1.7/bin/sumo-gui"

FolderPath = "C:/Users/garaw/Desktop/SUMO-Unity3D-connection-master/SUMO_Networks"

sumoCmd = [sumoBinary, "-c", FolderPath + "Network_01.sumocfg"]

traci.start(sumoCmd)

step = 0

while step < 1000:

    traci.simulationStep()

    if traci.inductionloop.getLastStepVehicleNumber("0") > 0:

        traci.trafficlight.setRedYellowGreenState("0", "GrGr")

    step += 1

 

traci.close()

 

Thanks for your help.

Regards,

Liesa Zimmermann
