pythia8 error about 'event_form'

Asked by feyndau

Hi,
I encountered a problem.
The version of madgraph is 2.6.3.2, and the version of pythia is 8.
I used "multi_run" to get more events, but afer that, the main files only had unweighted events, I wanted to ues command "pythia8 xxx" to get the file called "tag_1_pythia8_events.hepmc" . And problem came up as below.
Command "pythia8 stmbc" interrupted with error:
KeyError : 'event_norm'
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in '/home/feyndau/program/MG5_aMC_v2_6_3_2/test2/stmbc_tag_1_debug.log'.
Please attach this file to your report.

Thank you!

Hi,

indeed the standalone pythia8 command is broken in the latest version. This has been fixed in the development release of MG5aMC.

Thanks for reporting,

Olivier
