Hi MadGraph experts! I am trying to generate dihiggs events with an external model from: https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/HiggsPairProduction I placed the "tthh" model in MG5_aMC_v2.6.3.2/models. Importing the model gives me no problems. Also the command "generate p p > h h" works fine and I can see the produced diagrams with "display diagrams". However, when I do "ouput pp2hh" I gives me an error : """ Command "output pp2hh" interrupted with error: KeyError : (0,) """ Here is the whole log: """ [meiringp@dhcp-135-247 MG5_aMC_v2.6.3.2]$ ./bin/mg5_aMC ************************************************************ * * * W E L C O M E to * * M A D G R A P H 5 _ a M C @ N L O * * * * * * * * * * * * * * * * * * * * 5 * * * * * * * * * * * * * * * * * * VERSION 2.6.3.2 2018-06-22 * * * * The MadGraph5_aMC@NLO Development Team - Find us at * * https://server06.fynu.ucl.ac.be/projects/madgraph * * and * * http://amcatnlo.web.cern.ch/amcatnlo/ * * * * Type 'help' for in-line help. * * Type 'tutorial' to learn how MG5 works * * Type 'tutorial aMCatNLO' to learn how aMC@NLO works * * Type 'tutorial MadLoop' to learn how MadLoop works * * * ************************************************************ load MG5 configuration from input/mg5_configuration.txt fastjet-config does not seem to correspond to a valid fastjet-config executable (v3+).
