Top width set to auto error for dileptonic ttbar decay at NLO

Asked by Aminul Hossain

Hi

I am getting the following error when I run the following commands:

generate p p > t t~ [QCD]

where in the Madspin card, I specify the decay as follows:

decay t > w+ b, w+ > l+ vl
decay t~ > w- b~, w- > l- vl~

Then I set the top width to auto resulting in the following error:

Command "launch auto " interrupted in sub-command:
"set nlo_mixed_expansion False" with error:
FileNotFoundError : [Errno 2] No such file or directory: '/afs/cern.ch/user/a/ahossain/MG5_aMC_v3_5_4/tmpxmwmp58x/temp_decay/bin/internal/ufomodel/param_card.dat'
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in 'MG5_debug'.
Please attach this file to your report.

The command "set nlo_mixed_expansion False" was initially true but it gave the same error so I set it to false. Similarly I gave the command "set decay all auto" but that also gave me the same error. There is no BSM BSM reweighing.

The bug report is attached below:

Hi,

Thanks, I do reproduce the error.
So far both with Python3.8 and Python3.12
and also with version 3.5.4 and 2.9.19 (which surprise me a lot).

So I'm investigating what the reason is, I will keep you in touch when I will have a patch (or a work around).

Cheers,

Olivier

Here is a patch:
https://github.com/mg5amcnlo/mg5amcnlo/commit/101306bbb8e2653f99403f182ce1ab9712681346

Looks like one file was not correctly upgraded to python3 and this was not spotted so far.

Thanks,

Olivier

Hi

Thanks for the patch. I have naively copied the entire file and replaced it with the previous version in the loop_sm directory. This gives me the following error when running MadGraph using the command "./bin/mg5_aMC" :

    from .function_library import *
ModuleNotFoundError: No module named 'models.function_library'

I am not sure if it is due to the fact that I copied the file straight. Should I have rather opened up the python file on the terminal and edit only the required parts and saved it. I have begun to reinstall MadGraph and doing it manually. If it is due to some other error then do let me know.

Hi

Please ignore my previous message, I had copied it into the wrong directory which caused the previous error. It has now been fixed and MadGraph is compiling without any errors.

Thank you, the patch works.
