Hello,
Thank you for your responses Michael and Jakob. I tried with different
ports but it was the same result. Also tried using netstat to see if
there's other process using the port but I didn't found anything. This are
the errors on the command line:
dazuma$ python runner.py
Loading configuration... done.
Traceback (most recent call last):

When I used netstat while running sumo for the second time this is what
happened:

Any ideas?
