Re: [sumo-user] Using Python tools as reusable libraries 
Hi,
I adapted xml2csv in https://github.com/eclipse/sumo/commit/ff90fe8669fb0b1ff413c90d043ffdc5eb5b0941 to at least allow parsing a user defined argument list but I don't think we will put more effort into refactoring it. But we happily accept pull requests and patches :-). 

Best regards,
Michael

Hi Sasan,

you missed a comma before '-F'.
xml2csv.py needs some fixes to be used as library

Hi Harald,

 

Thanks for your reply. Yes, I have used the line in command line and
it works. Even from inside Python by os.system(…) it works. I am just
wondering why randomTrips works without any issues but xml2csv or
duaIterate don’t. xml2csv seems to have the same get_options class,
yet I can’t use it…

Hi Sasan,

 

duaIterate is callable as library as well as randomTrips.py

Some script called by duaIterate complains about missing trips, flows
or routes.

Have you tried calling duaIterate.py with the same parameters from the
command line?

 

Greetings

    Hi all,

     

    I am trying to use some of the Python scripts provided in the
    Tools folder of SUMO in my Python script as libraries. Basically,
    I want to avoid subprocess and executing python functions in
    shell. However, I have difficulties using them. For example I can
use the randomTrips.py as suggested in a previous question as follows: 

    randomTrips.main(randomTrips.get_options(['-n', 'your.net.xml']))

     

    However, this doesn’t work for duaIterate. There is no
    get_opetions class defined, So I thought I can just give in the
    arguments to the main class:

     

    duaIterate.main(['-n', ‘Net.net.xml', '-D', ‘taz.add.xml' '-F',
    'trips.trip.xml','-T', '-b', 0, '-e', '15000',
    '--router-verbose','--mesosim','-j'])

    ipykernel_launcher.py: error: Either --trips, --flows, or --routes
    have to be given!

     

    When I use the initOptions() class I get an error :

    duaIterate.main(duaIterate.initOptions(['-n', ‘net.net.xml', '-D',
    ‘taz.add.xml' '-F', 'trips.trip.xml','-T', '-b', 0, '-e', '15000',
    '--router-verbose','--mesosim','-j']))

    *TypeError*: initOptions() takes no arguments (1 given)

     

    I tried the same on xml2csv where the get_options class is defined
    (similar to randomTrips) but I get the same error:

    get_options() takes no arguments (1 given)

     

    Does anyone know how can I pass arguments to these python
    libraries? Or maybe they are just not written as a reusable
    library, which I doubt?

     

    Thanks,

    Sasan
