Re: [sumo-user] [WinError 10061]

Hello to all

My basic simulation code is written below. While I am running the same code
without restarting the Kernel, the following error message pops up.

*Could not connect to TraCI server at localhost:57376 [WinError 10061] No
connection could be made because the target machine actively refused it*

Due to this error message, I am unable to run the code in the loop. I also
checked for the firewall. There is nothing except "Windows Defender" which I
do not want to close. Is there any mistake in the code that I can rectify?


/import os, sys
if 'SUMO_HOME' in os.environ:
    tools = os.path.join(os.environ['SUMO_HOME'], 'tools')
    sys.path.append(tools)
    shapes = os.path.join(os.environ['SUMO_HOME'], 'tools','sumolib',
'shapes')
    sys.path.append(shapes)
else:
     sys.exit("please declare environment variable 'SUMO_HOME'")
