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]

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

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

Doing some quick research, one issue might be that the sumo version is too out-of-date: https://www.eclipse.org/lists/sumo-user/msg02480.html.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

SUMO Version 0.25.0

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.

The TraCI protocal changed in version 1.0.0.
Please make sure that TraCI client version and SUMO version match. @xiaoToby
