cannot connect to traci server #4686

priyabundela · 2018-10-10T04:50:13Z

i started my .py file from terminal using python command
then this error is coming . the sumo-gui opens but after that nothing happens . i put the limit for 60 seconds.

namdre · 2018-10-10T06:01:19Z

When starting sumo-gui there should be message output in the lower part of the window stating
Starting sever on port X*
Does the value of X must match the port where your python script is trying to connect? It's 56279 in your screenshot but this number may differ every time you start the script.

priyabundela · 2018-10-10T08:05:31Z

starting server on port X* is not appearing in the lower part of the window. the sumo-gui window just starts and nothing else appears.
I

priyabundela · 2018-10-10T08:08:38Z

should I start the sumo-gui from command line separately on a port and then run ,py file??

namdre · 2018-10-10T10:19:11Z

If your python script uses traci start (e.g. traci.start(['sumo-gui', '-c', 'example.sumocfg'])) then sumo is started automatically with the correct port setting.

priyabundela · 2018-10-10T12:10:11Z

Yes I am doing this only . BT window just starts but it don't starts the configuration file . Also it keeps trying to connect to traci served

import os , sys

import environment

tools = os.path.join(os.environ['SUMO_HOME'], 'tools')
sys.path.append(tools)

sumoBinary = "/home/priya/sumo/bin/sumo-gui"
sumoCmd = [sumoBinary, "-c", "/home/priya/sumo/tests/complex/tutorial/q-learning/my_config_file.sumocfg"]
import traci
traci.start(sumoCmd)
environment.test_workflow()
#traci.close()

this is what I am doing

namdre · 2018-10-10T14:43:03Z

what are the contents of my_config_file.sumocfg ?

priyabundela · 2018-10-10T16:04:34Z

I don't think there are errors in this file as I am able to run separately from sumo-gui

namdre · 2018-10-10T17:01:35Z

Nevermind, I was thinking there might be a superfluous port option.
Can you attach a screenshot of sumo-gui after it has been started by your script?

priyabundela · 2018-10-10T17:25:19Z

namdre · 2018-10-10T21:37:46Z

@behrisch Do you have any Idea what could prevent the message output
WRITE_MESSAGE("***Starting server on port " + toString(port) + " ***");
?

behrisch · 2018-10-11T08:14:02Z

Is there any very restrictive firewall running? Did you try it with the command line sumo ("sumo" instead of "sumo_gui")?

priyabundela · 2018-10-11T12:30:21Z

no there is no restrictive firewall running. ya I tried this also . did not work.
if I am starting sumo on some port with remote port option with the config file . it prints the message . "starting server on port X" .
but i don't know why its unable to connect to traci server.

namdre · 2018-10-11T12:38:56Z

for debugging, run
sumo-gui -c my_config_file.sumocfg --remote-port 9999
and in your script replace traci.start() with trac.init(9999), then run the script

s-dasgupta · 2021-07-02T18:38:16Z

I am having the same error. Everything was working fine before restarting my PC. But after the restart, I am getting the following error.
"
Retrying in 1 seconds
Could not connect to TraCI server at localhost:53361 [WinError 10061] No connection could be made because the target machine actively refused it.
"
What should I do??

behrisch · 2021-07-19T14:54:01Z

Did you try to specify a port manually just as mentioned above?

behrisch · 2021-09-23T15:03:34Z

There may be a local firewall blocking socket access

behrisch · 2021-09-23T15:03:54Z

But please rather open a new ticket and attach your scenario if possible

@monasabeti The best way to start up traci is to call traci.start not init. Please try to follow the traci tutorials at https://sumo.dlr.de/docs/Tutorials/index.html#traci_tutorials

monasabeti · 2021-12-09T15:46:30Z

thanks alot for your respond

I was facing same problem i pressed go live option in right bottom corner and after that i used pip install traci in powershell. now i am able to simulate.

mayaaarahayu1 · 2023-07-05T03:38:47Z

Hi, I'm maya that also working with sumo simulation. Can I discuss this with you? because I'm facing a similar problem.

I should add to this, though possibly this should be added to a FAQ, that this error will also be caused by an incorrect file name.

for example I had a myconfig.sumocfg.xml file and traci was specifying a myconfig.sumocfg. The result was the error in this very report.

muhammadsohaib60 · 2023-12-04T16:18:27Z
