Re: [sumo-dev] Sumo not opening properly while using python, please help :(
make sure the file has a root element (i.e.) `<additional>` and then also a closing element `</additional>`.  When in doubt, use netedit to define the detectors (until you are used to working with the raw xml).

Sorry if my first message was kind of ambiguous. When I try to add e1detectors with id 1 and 2, I got the following error when the sumo-gui opens and the cfg is no loaded:

I don't know if I should regenerate some files or how to do that. I know that the problem is caused by adding the new detectors, but what I want to know is how can I add more e1detectors (one on every lane).

"my sumocfg is not loading anymore" does not carry enough information to help you out.
There should be an error message that guides you towards a solution (if so, you may ask to clarify it's meaning) or if the simulation crashes without an error, then this is something you need to state clearly.

I have a question regarding the tutorial. I saw that in tutorial there is only one detector, on lane 4i_0. When I try to add another e1detectors on other lanes, my sumocfg is not loading anymore. What should I do if I want to add more detectors after I added them manually in .det file?

Sorry if is too much, but can you please show me how should i write the begging of the code, only to open the gui and start the simulation?

sumo stopped because your python script (the "peer") crashed. You should find the solution by investigation the stack trace from your python code.

I tried both of the sumo_cmd commands from above, but the same results.

The sumo-gui opened but when i press start, i got this and nothing happens afterwards.
Can you please help me to find the problem and how to solve it?
Thank you for your time and have a nice day,
A worried student.
