SUMO File Locations

Do the configuration files have to be in the same directory/drive where SUMO has been installed like C:/ ? If not will it cause errors while trying to load files through Python using TraCI ?

The reason I ask is that I created a sumo configuration file using net and route files to run through Python. I followed the instructions on the SUMO website. But when I try to run it through python I get the following error.

Retrying in 1 seconds Could not connect to TraCI server at localhost:51818 [WinError 10061] No connection could be made because the target machine actively refused it Retrying in 1 seconds Could not connect to TraCI server at localhost:51818 [WinError 10061] No connection could be made because the target machine actively refused it Retrying in 1 seconds Could not connect to TraCI server at localhost:51818 [WinError 10061] No connection could be made because the target machine actively refused it Retrying in 1 seconds Could not connect to TraCI server at localhost:51818 [WinError 10061] No connection could be made because the target machine actively refused it Retrying in 1 seconds

FatalTraCIError: Could not connect in 61 tries*

The code I am using is the following:

import os, sys
import subprocess
import sumolib

if 'SUMO_HOME' in os.environ:
tools = os.path.join(os.environ['SUMO_HOME'], 'tools')
sys.path.append(tools)
else:
sys.exit("Please declare the environment variable 'SUMO_HOME'")

sumoBinary = "C:/Program Files (x86)/Eclipse/Sumo/bin/sumo-gui.exe"
sumoCmd = [sumoBinary, "-c", "hegyi_net.sumocfg"]

import traci

traci.start(sumoCmd)

traci.close()

SUMO-version: 1.16

operating system: Windows 11

As a result, I tried uninstalling and reinstalling SUMO, running other .sumocfg files, getting log files, and just trying to open the sumo-gui through Python(which works), but it does not open any config files. I just want to ask before I do anything else and cause additional issues which might take longer to solve.

SUMO's config files do not have to be in the installation directory and can also be in a different directory than the referenced files. I suppose you are just not in the correct directory. Try to give the absolute path to the config when loading it.
