MadGraph Web Platform not generating processes

Asked by Diogo Franco Graça Pires on 2020-10-10

Hello!

I am trying to generate a very simple "e e+ > u u~" process on the web platform but with no success.

I am filling the form accordingly, and I click "Submit". Afterwards, however, I always end up stuck while the generating of process is "under preparation".
I then click on "Generation progress/status", to find one of two error messages (depending on the computer, both Macs):

1) MadGraph5_aMC@NLO works only with python 2.7 or python 3.7 (and later).
  You are currently using Python2.6. Please use a more recent version of Python.
Warning: The script ./bin/mg5 will be removed in future versions; use ./bin/mg5_aMC instead.

OR

2) madgraph requires the six module. The easiest way to install it is to run "pip install six --user"
in case of problem with pip, you can download the file at https://pypi.org/project/six . It has a single python file that you just need to put inside [...] variable.
[91Warning: The script ./bin/mg5 will be removed in future versions; use ./bin/mg5_aMC instead. [0m

Again, I am running on the Web platform "http://madgraph.physics.illinois.edu".

How should I proceed in order to solve this?

Thank you for the help!

Hi,

Looks like the web server has some issue with our recent move to python3.
I will see what I can do on Monday.

Thanks for the notification,

Olivier

Thanks for the quick reply, Olivier.

Hope it's a quick fix :)

Best,

Hi Diogo,

I have a good news and a bad news.
The good news is that I have installed a newer python version and that allow to generate the various processes on the machine.
The bad news is that the condor job scheduler is down which prevents you to run the code online (i.e. to compute cross-section and to generate events).

I have send a request to IT team in charge of that cluster to see what's going on but I'm afraid that they will be even less responsive than me...

I'm afraid that the best course of action for you is to install the code on your computer and to run it locally.

I'll obviously update this thread when I would hear from the admin.

Sorry,

Olivier

Hi Olivier,

Thank you for your efforts!
Hopefully whatever is going on can be easily solved.

I'll try and go ahead with running it locally.

Thanks,

Diogo
