Re: [sumo-user] FatalTraCIError: connection closed by SUMO

Hello,

possibly, sumo itself aborts with an error due to invalid input files. If you cannot see any log output from sumo on your console, add the sumo option -l log.txt  when starting sumo and then log into log.txt afterwards,

regards,

Jakob

Hi!

I'm getting an error using TraCI and SUMO (version 0.32.0). The error code is posted below. I read that with previous version the problem was the mesa library. I tried intalling suggested packages, but it still didn't work. Could there be another problem?

Error code: 

Traceback (most recent call last):
File "/home/annika/kool/Thesis/implementation/model.py", line 336, in <module>
traci.simulationStep()
File "/usr/local/share/sumo-0.32.0/tools/traci/__init__.py", line 111, in simulationStep

raise FatalTraCIError("connection closed by SUMO")
traci.exceptions.FatalTraCIError: connection closed by SUMO

Process finished with exit code 1

All the best, 

Annika
