Re: [sumo-user] SUMO version and platform problems
The most likely cause is a version mismatch.
Please determine the value of TRACI_VERSION from
/usr/local/share/sumo/tools/traci/constants.py that is used within your version 1.0.1 ubuntu docker (found in line 22 of the file).
This value should be 18 for version 1.0.1. and lower values will not work.

regards,
Jakob

Hi all,

I encountered one problem, I installed SUMO 1.0.1 on win7 and Ubuntu 16.04 successfully, and ran the same code piece, then I found it works well on Win7 but failed in Ubuntu docker. At the same time, I started another docker to install SUMO 0.32.0 on Ubuntu, I found the same code piece work well also.

My code is very simple, shown as followed, and the attachment provide all the used input file, I tried to use –log, but no output.

 

import traci

sumo_cmd="sumo-gui --net-file luxiang_lize.net.xml --route-files POC3wdv6ie2.rou.xml" \

         " --tripinfo-output trip_log_0b54w98fc.xml --additional-files addition_0ubaqj5y0add.xml,addition2_0t9fipyubadd.xml,addition3_0p9zlyw08add.xml"

sumo_cmd=sumo_cmd.split(" ")

cnt=2902

while True:

    cnt+=1

    print(cnt)

    traci.start(sumo_cmd,cnt)

    simulate_count = 0

    while simulate_count < 11000:

        print(simulate_count)

        simulate_count += 1

        traci.simulationStep()

traci.close()

 

 

The error message of SUMO 1.0.1 on Ubuntu is  

Traceback (most recent call last):

  File "/mnt/test/test/test.py", line 20, in <module>

    traci.simulationStep()

  File "/usr/local/share/sumo/tools/traci/__init__.py", line 149, in simulationStep

    responses = _connections[""].simulationStep(step)

  File "/usr/local/share/sumo/tools/traci/connection.py", line 323, in simulationStep

    result = self._sendExact()

  File "/usr/local/share/sumo/tools/traci/connection.py", line 99, in _sendExact

    raise FatalTraCIError("connection closed by SUMO")

traci.exceptions.FatalTraCIError: connection closed by SUMO
