Hello,
I am attempting to start a SUMO simulation using a python script.
1. I have successfully started the simulation manually using the configuration, network and trip files.
2. When I attempt to start the simulation programmatically, the sumo-gui is successfully started, the configuration files too are successfully loaded, but traci.start API in my python script does not return ( as print statement after traci.start are not printed )
Loading configuration... done.
***Starting server on port 58474 ***
Loading net-file from 'C:/Users/XZ01M2/Desktop/Work/AI/github/Deep-Qlearning-TSC/intersection/intersection.4L.net.xml'... done (9ms).
Loading done.
3. When I close the launched sumo-gui.exe manually, the connection is closed and I see that the API is stuck somewhere within getVersion function trying to communicate with sumo-gui over the established connection.

Any help will be appreciated
