Hi Harald, hi Jakob,
I tried to do what Harald recommended. (took me some time, as I faced a few problems on my way, but now almost all are solved)
The last step in which I am supposed to do:
gdb --args sumoD -c debug.sumocfg
gives me back:

sumoD: No such file or directory.

even if sumoD exists...

To double-check I tried in the terminal:

weronika@MBP-Weronika ~ % sumo-gui

(this worked)

weronika@MBP-Weronika ~ % sumo-guiD

zsh: command not found: sumo-guiD


Do you know what could I try to solve it?


Today I wanted also to try what Jakub recommended.

My traci.start is:

traci.start([sumoBinary, "-c", '../' + selectedFolder + '/osm.sumocfg',
             "--tripinfo-output", '../' + selectedFolder + '/out/tripinfo.out.xml',
             "--summary-output", '../' + selectedFolder + '/out/summary.out.xml',
             "--netstate-dump", '../' + selectedFolder + '/out/netstate.out.xml',
             "--vehroute-output", '../' + selectedFolder + '/out/route.out.xml',
             "--duration-log.statistics", "true",
             "--log", '../' + selectedFolder + '/out/log.txt',
            traceFile="traci.log",
             "--vehroute-output.route-length", "true"])
Adding it directly like this doesnt work, as it is invalid syntax I will need to adapt it to my traci.start... (I tried a few modification, but without any success) Could you please help my with how to do it?
Thank you for your support
best,
Weronika

Alternatively, you can run your project with traci.start(..., traceFile="traci.log") and send in your input files along with traci.log.

Hi Weronika,

it may be, that Sumo terminates unexpected.

Please build the Debug version and run SUMO with gdb.

If Sumo terminates, the stack trace can help the developers

See https://sumo.dlr.de/docs/Installing/Linux_Build.html#building_the_sumo_binaries_with_cmake and https://sumo.dlr.de/docs/TraCI/Interfacing_TraCI_from_Python.html#debugging_a_traci_session_on_linux

Best regards, Harald

Hi!

I got a new build of SUMO and I am getting an error traci.exceptions.FatalTraCIError: connection closed by SUMO.  The last time when I ran it and it worked properly was with the build from ~15.06.

(The problem already appeared before when I used the build from 12.07, but I left it as I thought maybe will not occur later.)


Traceback (most recent call last):

traci.exceptions.FatalTraCIError: connection closed by SUMO



I tried: „>> run your simulation with the option --duration-log.statistics and --log

>> logfile.txt

>> you will find the results in logfile.txt”

When the simulation gets this error the log file is empty.


Worth to mention is that at the beginning of my simulation I set up a number for using randomTrips.py and generate trips file


command = 'python ' + os.environ['SUMO_HOME'] + '/tools/randomTrips.py -n osm.net.xml -p ' + vehiclesDensity +' -o trips.trips.xml '+ '--trip-attributes=\'departLane=\"best\" departSpeed=\"max\" type=\"car\" departPos=\"random\"\' --validate'

os.system(command)


And depending on this argument the simulation fails or not (mostly fails..).


I would appreciate your help on how I can find the problem. I checked the input files and they look fine (and works with earlier versions)


Best,

Weronika
