Thanks,

Looks like a problem in the pythia8 interface.

Hi Olivier,

I have got a similar bug...

Command "generate_events run_01" interrupted with error:
TypeError : gzip() got an unexpected keyword argument 'keep'
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in '/home/kumar/Documents/tools/MG5_aMC_v2.6.7/MG5_aMC_v2_6_7/bin/0nunub_30_106/run_01_tag_1_debug.log'.
Please attach this file to your report.

and here is log file:

To me, it seems to be a problem related to ExRootAnalysis. Please have a look.

Best regards,

Thanks,

This will be fixed in the next release.

Cheers,

Hey,

This error occured to me too. I am using 2.6.7. Was the fix included in this version?

[Olivier Mattelaer (olivier-mattelaer)]

The bug report was about 2.6.7. So 2.6.7 is indeed impacted by that bug.
