Re: [sumo-user] [EXTERNAL] Re: Carla Simulator Support for SUMO generate

Hello,

I am writting because I am interested if there was any new development/ insights as to why SUMO generated OpenDrive files cannot be parsed in the Carla Simulator.

Thank you again for Your effort,

Gregor Ovsenjak

Hello again, I am also sending You a Carla warnings txt. Maybe this can also help.

Thank You,

Hello again,

thank You for answering so quickly. I am using the windows development version of SUMO I downloaded on 16.02.2022 (https://sumo.dlr.de/docs/Downloads.php). The file works with Esmini simulator, but not in Carla. Here are the steps for generating the ODR file.

1. Osm2Sumo --> netconvert --osm-files ./OSM/osmfile.osm -o ./SUMO/sumofile.net.xml --osm.all-attributes --speed-in-kmh --geometry.remove --junctions.join --output.street-names --osm.extra-attributes all                                                                                 
2. Sumo2Odr --> netconvert -s ./SUMO/sumofile.net.xml --opendrive-output ./SUMOopendrive.xodr                                                   
3.  I take the Sumo generated OpenDrive (CarlaTest.xodr) file to Carla and try to parse it with the command-->                              python3 config.py -x opendrive/SUMOopendrive.xodr
4. I get an error that simply states : opendrive could not be correctly parsed.

With kind regards,

Gregor Ovsenjak

Thank you for bringing this up. I was not aware Carla had an issue with SUMO-generated OpenDRIVE and have invited their developers to report their problems. If you can provide a (small) example for reproducing the problem, that would also help: ZjQcmQRYFpfptBannerStart

Thank you for bringing this up. I was not aware Carla had an issue with SUMO-generated OpenDRIVE and have invited their developers to report their problems.

If you can provide a (small) example for reproducing the problem, that would also help:

-a netconvert-generated xodr file that carla cannot load

- all the inputs/options that were used to generate the above xodr

- a description of the required steps to trigger the carla error

regards,

Jakob

Hello,

thank You for all the nice answers You provided. I have a question about the support for CARLA simulator. Recently I tried visualizing the SUMO generated OpenDrive file with the Python API from CARLA. However I ran into an error that says CARLA  simulator cannot parse the OpenDrive file that was generated by SUMO.

My question is, do You perhaps now why Carla cannot correctly parse the SUMO generated OpenDrive file ?

From an answer ( https://github.com/carla-simulator/carla/issues/3009#issuecomment-653010988 ), they said that the error has something to do with junctions. I don't know what exactly they mean. 

Any feedback will be much appreciated.

With kind regards,

Gregor Ovsenjak
