Hi Michael and Marcelo,
with the latest version of the example I could reproduce the error.
With some changes to sumo_env.py
*** sumo_env.py 2021-05-12 08:29:23.260183300 +0200
--- sumo_env.py.orig 2021-05-10 14:22:32.000000000 +0200
***************
*** 283,287 ****
sumo_binary = self.get_sumo_binary(gui=False)
! sumo_cmd = []
! sumo_cmd.extend(['gdb', '-ex', 'run', '--args'])
! sumo_cmd.extend([sumo_binary, *sumocfg_parameters_list])
--- 283,285 ----
sumo_binary = self.get_sumo_binary(gui=False)
! sumo_cmd = [sumo_binary, *sumocfg_parameters_list]
I run all sumo's with gdb and I got
SUMO VERSION SUMO v1_9_1+0287-bf4d10a8fa

Hi,
I just ran it from the command line not in an IDE. I probably

Best regards,
