Re: [sumo-user] Error on traci.person.getTaxiReservations(0)

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

This is because the traci library version does not match the sumo version (1.9.0 has 10 instead of 9 reservation parameters).

Compare /usr/share/sumo/tools/traci/_person.py with the 1.9.0 version: https://github.com/eclipse/sumo/blob/0d34f1f23bdec0abd25a8b61dc21433b4208bbff/tools/traci/_person.py

Hi,

 

I’m using the example

/tests/complex/traci/vehicle/taxi/basic/runner.py

 

The very STRANGE fact:

the example runs without error on one computer (Ubuntu 20, sumo 1.9.0, 32GB RAM)

 

On another computer (VM, same OS, same sumo version, 4GB) I get:

 

Retrying in 1 seconds

Loading configuration ... done.

***Starting server on port 50661 ***

Loading net-file from 'input_net4.net.xml' ... done (12ms).

Loading done.

Simulation version 1.9.0 started with time: 0.00

taxiFleet ('taxi_0',)

Traceback (most recent call last):

  File "runner.py", line 61, in <module>

    reservations = traci.person.getTaxiReservations(0)

  File "/usr/share/sumo/tools/traci/_person.py", line 246, in getTaxiReservations

    result.append(_readReservation(answer))

  File "/usr/share/sumo/tools/traci/_person.py", line 63, in _readReservation

    assert(result.read("!i")[0] == 9)

AssertionError

Quitting (on error).

DijkstraRouter answered 1 queries and explored 1.00 edges on average.

DijkstraRouter spent 0.00s answering queries (0.00ms on average).

 

Any ideas how to fix this are highly appreciated.

 

Best regards

Andreas
