Re: [sumo-user] Libsumo for python

[Didac Busquets <didac.busquets@xxxxxxxxxx>]

Hi Michael,

I recompiled everything and now it works.

I now have another question. I'm using libsumo and subscriptions, and have some code similar to this:

libsumo.lanearea.subscribe(one_area, (libsumo.constants.LAST_STEP_OCCUPANCY,libsumo.constants.JAM_LENGTH_METERS))
...
result = libsumo.lanearea.getAllSubscriptionResults()

The type of result is SwigPyObject. How should I handle it to get the results of subscriptions?

Thanks,

	Didac

Hi Didac,
it should not be necessary to have tools/libsumo in the python path.
Where does SUMO_HOME point to?

Best regards,
Michael
