Pythia8 shower failed

Asked by Amit Adhikary on 2018-05-03

Hi,

I get the same bug message while doing a matching process in both "MG5_aMC_v2_6_2"(latest) and "MG5_aMC_v2_5_5" as in the ticket "https://bugs.launchpad.net/mg5amcnlo/+bug/1674341" showing :
InvalidCmd : Pythia8 shower failed since it did not accept any event from the MG5aMC event file

Then, I tried with what Olivier suggested :

patch lhe_parser.py empty_file.patch

But, this gave me the following output :
--------------------------------------------------------------------------
patching file lhe_parser.py
Hunk #1 FAILED at 173.
Hunk #2 FAILED at 233.
Hunk #3 FAILED at 258.
Hunk #4 FAILED at 2604.
4 out of 4 hunks FAILED -- saving rejects to file lhe_parser.py.rej
--------------------------------------------------------------------------
and the problem persists.

I got "Python 2.7.12" version installed. I am wondering that I have missed something. Please let me know, if there is something else I need to do to avoid this bug.

Thanks,
Amit

HI,

The patch is already included in the latest version and therefore it is irrelevant to apply such patch.

Is it working when you run in single core?

Can you give more details on what you are doing?
At first view, It should not be the same bug as 2.5.x since this was python2.6 specific if I remember correctly.

Cheers,

Olivier

Thanks Olivier, I missed the point of using a single core. It's working now.
