Warning Message : Is it serious

Asked by shibasipu

Dear Olivier,
                              Sorry for posting so many error messages and warnings. Last month onwards, I am getting so many error messages and warnings. Please have a look to the warning message given below. Can I trust the cross section , coming at the end ?

INFO: Refine results to 10000
/home/poulose/Barbarossa/SUBHASISH/EVENT_GENERATORS/MG5_aMC_v2_3_3/madgraph/madevent/gen_ximprove.py:746: DeprecationWarning: object.__new__() takes no parameters
  return super(gen_ximprove, cls).__new__(gen_ximprove_v4, cmd, opt)
/home/poulose/Barbarossa/SUBHASISH/EVENT_GENERATORS/MG5_aMC_v2_3_3/madgraph/madevent/gen_ximprove.py:752: DeprecationWarning: object.__init__() takes no parameters

Hi,

Those are warning specifying that python will break retro-compatibility with our code in a future version.
Funny enough this warning is only raise on Linux and on python2.6 (if I’m correct) this do not happen with python 2.7

Cheers,

Olivier

Thanks. That means I can trust on the cross section. Is it right ?

Dear Olivier,
                          Does my result depend on those warnings ? Actually, I am getting some strange result (i mean cross section). That's why I am worrying about these warnings.

Hi,

As I said this is just a warning saying that our code will not work with a future version of python.

If you have strange results then clearly you can not trust the result as long as you do not understand your result and/or what you did wrong.

Cheers,

Olivier
