name 'function_library' is not defined

[Keping Xie]

Hi guys, I am Keping Xie, working on implementation of new models called SCTM in MadDM. I generated the UFO file with SARAH and want to invoke MadDM to do Dark Matter study. The UFO file is attached, which works for MG5_aMC cross section calculations. However, when I work MadDM with the following commands,

./bin/maddm.py
import model SCTM -modelname
define darkmatter n1

It returns the following message.
Command "define darkmatter n1" interrupted in sub-command:
"import model /home/kepingx/MG5_aMC/MG5_aMC_v2_6_1/models/SCTM__REAL --modelname" with error:
NameError : name 'function_library' is not defined
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in 'MG5_debug'.
Please attach this file to your report.

Is this error related to the mass spectrum? My param_card.dat generated by SPheno is also included in the attachment.

I also tried Download the latest maddm_V2.1.1.tar.gz, and work in the un-tared directory with following procedure, which is also problematic.

Enter model name (press Enter to list the available models): SCTM
Enter project name (SCTM): SCTM_DM
Calculate relic density? [y] (y/n)y
Calculate direct detection cross sections? [y] (y/n)n
nEnter DM candidate (press Enter to automatically find the DM candidate):
 (Enter 'particles' to see a list of particles)
 *** Exclude particles via the standard MG "/" notation

So, what is the reason for this problem? Is my UFO file not compatible with MadDM?

Best regards,

Hi,

Sorry for getting back to you so late.
We notice a miss-configuration in our bug tracker and notice this report only today.

At first look this seems to be an issue on how SARAH generates the model.
The error :
NameError : name 'function_library' is not defined
seems related to the fact that
__init__.py does not have the line import function_library
Actually, FeynRules also does not include this line and I do not understand how this does not make FeynRules model to crash. (the latest version of FR fixes that issue)

Sorry for the very long delay,

Olivier
