Dear All,
I implemented 2 python classes (stepListeners) that require to use
traci.subscriptions
(http://sumo.dlr.de/wiki/TraCI/Interfacing_TraCI_from_Python#Subscriptions).
These classes are independent from each other, and in some cases have
overlapping subscriptions
(subscriptions to the same elements). I cannot change the classes (for
compatibility reasons), so
I'm trying to use:
- multiple clients, one for each class
(http://sumo.dlr.de/wiki/TraCI/Interfacing_TraCI_from_Python#Controlling_the_same_simulation_from_multiple_clients).
- from the same _main() function
(http://sumo.dlr.de/wiki/TraCI/Interfacing_TraCI_from_Python#Controlling_parallel_simulations_from_the_same_TraCI_script)
I tried all the possible ordering of start/init, getConnection, setOrder and
they hang on line 2
(Loading configuration... done. ***Starting server on port 59759 ***)
"""
1 # TraCI client #1
2 traci.start(['sumo', '-c', '../MoSTScenario/scenario/most.traci.sumocfg',
3 '--num-clients', '2'], port=59759, label='pypml')
4 # TraCI client #2
5 traci.init(port=59759, label='triggers')
6
7 _pypml_handler = traci.getConnection('pypml') # with and without
simulationStep() after.
8 _pypml_handler.setOrder(1) # number can be anything
9 logging.info('PyPML TraCI client acquired.')
10
11 _triggers_handler = traci.getConnection('triggers')
12 _triggers_handler.setOrder(2) # number can be anything
13 logging.info('Triggers TraCI client acquired.')
"""
If I use them one at the time (connections only / multiple clients in separated
files) all works
fine. Is there a way to use these 2 functionalities together?
Thanks in advance for your time :)
All the Best,
Lara
