ValueError : need more than 5 values to unpack

Asked by Josh McFayden on 2018-07-16

Hi all,

I'm trying to run W(actually lv)+4j@LO gridpack production on the CERN lxbatch cluster.
My run finishes with:
...
INFO: All jobs finished
ValueError : need more than 5 values to unpack
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in '/afs/cern.ch/work/m/mcfayden/mcgen/MadGraphControl/testing/testForTatsumi/run/Wtau_363666_mkGridpack/PROC_sm-no_b_mass_0/Test_tag_1_debug.log'.
Please attach this file to your report.

What is the cause of the crash?

Also, I can still make the gridpack by doing:
PROC_sm-no_b_mass_0/bin/madevent
PROC_sm-no_b_mass_0>combine_events help
...
PROC_sm-no_b_mass_0>store_events
...
PROC_sm-no_b_mass_0>create_gridpack
...

But is it safe to use? Are these checks that all the subjobs return suitable output?

Best,

Josh

Hey there! Any news on this?

Hi,

What is written in the debug file.
This error indicates an error in one of the fortran job.
So It is not save to create the gridpack a priori.

We might have more information in the debug file.
saying which channel is problematic but it might not be the case.
if not,
you can try to search the word "error" in all the results.dat file.

Cheers,

Olivier
