CARLA netconvert_carla.py not converting .xodr to .net.xml for SUMO >1.8.0

[svanimisetti]

CARLA version: 0.9.13 Platform/OS: Windows 10 Problem you have experienced: netconvert_carla.py is fails to convert OpenDRIVE files What you expected to happen: SUMO .net.xml files should have been created - but there is an error instead.

Steps to reproduce:

1. CARLA for Windows setup in C:\apps\CARLA
2. SUMO setup in C:\apps\sumo-1.9.0
3. Create following test script at `%USERPROFILE%\Desktop\convert_xodr.py

import os, sys, glob

os.environ['CARLA_HOME'] = 'C:/apps/CARLA'
os.environ['SUMO_HOME'] = 'C:/apps/sumo-1.9.0'

egg_file = glob.glob(os.path.join(os.getenv('CARLA_HOME'),
    'PythonAPI/carla/dist/carla-*%d.%d-%s.egg' %
    (sys.version_info.major, sys.version_info.minor,
    'win-amd64' if os.name == 'nt' else 'linux-x86_64')))[0]
sys.path.append(egg_file)
import carla

sys.path.append(os.path.join(os.getenv('SUMO_HOME'),'tools'))
os.environ['PATH'] = os.pathsep.join(
    [os.path.join(os.getenv('SUMO_HOME'),'bin'),os.getenv('PATH')])

carla_sumo_dir = os.path.join(os.getenv('CARLA_HOME'), 'Co-Simulation/Sumo')
if os.path.isdir(carla_sumo_dir):
    sys.path.append(carla_sumo_dir)

from util.netconvert_carla import netconvert_carla

xodr_file = os.path.join(os.environ['USERPROFILE'],'Desktop','Town01.xodr')
net_file = os.path.join(os.environ['USERPROFILE'],'Desktop','Town01.net.xml')
netconvert_carla(xodr_file, net_file, guess_tls=True)

4. Copy Town01.xodr to Desktop from C:\apps\CARLA\CarlaUE4\Content\Carla\Maps\OpenDrive\Town01.xodr
5. Run cd %USERPROFILE%\Desktop && python convert_xodr.py and it produces following error.

proj_create: Error -38 (failed to load datum shift file): vgridshift: could not find required grid(s).
Error: Could not set projection. (Could not build projection!)
Quitting (on error).
Traceback (most recent call last):
  File "convert_xodr.py", line 25, in <module>
    netconvert_carla(xodr_file, net_file, guess_tls=False)
  File "C:/apps/CARLA\Co-Simulation/Sumo\util\netconvert_carla.py", line 521, in netconvert_carla
    _netconvert_carla_impl(xodr_file, output, tmpdir, guess_tls)
  File "C:/apps/CARLA\Co-Simulation/Sumo\util\netconvert_carla.py", line 394, in _netconvert_carla_impl
    raise RuntimeError('There was an error when executing netconvert.')
RuntimeError: There was an error when executing netconvert.

6. Now change line 4 in convert_xodr.py to os.environ['SUMO_HOME'] = 'C:/apps/sumo-1.8.0' or any SUMO version <=1.8.0.
7. Re-run convert_xodr.py and this time it converts the .xodr without any issue.

This seems to be an issue with newer version of SUMO - which may be using some new specifications for OpenDRIVE. Not sure, but the issue is reproduced in multiple machines.

I cant understand how to resolve this issue. I'm attaching the error screenshot for your further help. best,

For the record: Updating sumo should help.

CARLA : 0.9.14 Sumo - 1.17.0 OS-Ubuntu 20.04 ( focal) ~/Downloads/CARLA_0.9.14/Co-Simulation/Sumo/util$ python3 netconvert_carla.py Town05.xodr Error: File 'Town05.xodr' is not accessible (No such file or directory). Error: No nodes loaded. Quitting (on error). Traceback (most recent call last): File "netconvert_carla.py", line 541, in netconvert_carla(args.xodr_file, args.output, args.guess_tls) File "netconvert_carla.py", line 521, in netconvert_carla _netconvert_carla_impl(xodr_file, output, tmpdir, guess_tls) File "netconvert_carla.py", line 394, in _netconvert_carla_impl raise RuntimeError('There was an error when executing netconvert.') RuntimeError: There was an error when executing netconvert.

I have the same problem with latest version of CARLA and Sumo simulator both.

How to resolve this?

Please try calling netconvert directly according to the options found in netconvert_carla.py:

netconvert --opendrive-files yourfile.xodr --output-file sumo.net.xml --geometry.min-radius.fix --geometry.remove --opendrive.curve-resolution 1 --opendrive.import-all-lanes --output.original-names --tls.discard-loaded true

also, check whether you are using 1.17.0 by calling netconvert without arguments which should report the version number.

Thank you sir for your reply. I would try this.

It's working perfectly. Thank you so much for your help.
