Hello Julien,
this message is given when the script is called without the path to the
SUMO network file. You do this using the -n/--net switch: "-n
path/to/your/net.net.xml". Have a look at the option list in the SUMO docs.
Regards
Mirko

Hello,
We are French students and we use Sumo for a project.
We have a problem with the software. We want to make a visualization
(like colored map or diagram) of a simulation in SUMO. We looked at
the tuto ( https://sumo.dlr.de/docs/Tools/Visualization.html) and the
FAQ on the website. We use SUMO version 1.3.1 .
We execute the program “plot_net_dump.py” for example with “spyder”
which is a python software. But it doesn’t work and we have this
error’s message :
“
Error: a network to load must be given.
An exception has occurred, use %tb to see the full traceback.
SystemExit: 1
“
Could you give me more details of how make visualization of simulation ?
Cordially
