Error with commandline when running examples/sumo/sugiyama.py #395

Closed KidTrunks closed 5 years ago

KidTrunks commented 5 years ago

Versions: Ubuntu 16.04 Python 3.5

Problem: The following error codes occur after running examples/sumo/sugiyama.py

Loading configuration... done. Success. Error: On processing option '--num-clients': No option with the name 'num-clients' exists. Error: The parameter '1' is not allowed in this context. Switch or parameter name expected. Error: On processing option '--collision.check-junctions': No option with the name 'collision.check-junctions' exists. Error: The parameter 'true' is not allowed in this context. Switch or parameter name expected. Error: Could not parse commandline options. Quitting (on error). Could not connect to TraCI server at localhost:51587 [Errno 111] Connection refused Retrying in 1 seconds Could not connect to TraCI server at localhost:51587 [Errno 111] Connection refused

The sumo gui pops up with the above error codes. Flow had already been activated with 'source activate flow.' Any help would be appreciated.

Thanks!

Hi, I met the same problem, have you figured it out?

KidTrunks commented 5 years ago

Hi @JeanUCD,

Not yet unfortunately. Please let me know if you figure anything out.

Thanks.

Hi all, thank you for bringing this up. I will look into it and get back to you ASAP.

AboudyKreidieh commented 5 years ago

Doing some quick research, one issue might be that the sumo version is too out-of-date: https://www.eclipse.org/lists/sumo-user/msg02480.html.

Can you share with me your sumo version? You can get it by typing sumo in your terminal. You should get something like this:

SUMO Version v0_31_0-812-g1d4338ab80
 Build features: x86_64-pc-linux-gnu TRACI PROJ GDAL GUI

 Use --help to get the list of options.

Thanks for your help. Here is my sumo version:

AboudyKreidieh commented 5 years ago

Hey, yes that seems to be the issue. Certain options we are calling are only available for sumo version from 0.31.0 and above. I would recommend following our setup instructions to get the current sumo version on your local machine.
