KeyError failure on "output" command

[Luca]

Dear experts,

I am trying to generate gg > HH events in MadGraph5_aMC@NLO.
I have a workflow that worked properly in a previous code version (v2.6.1).
However, as I switched to the latest release (v2.6.3.2), I get the error [1] upon calling the "output" command.
I am attaching the debug file if that can be useful.
A minimal set of instruction to reproduce the problem is in [2].

Although the model is not the most recent one, it would be good to have the capability to run it to test against newer implementations, but unfortunately v2.6.1 is not available anymore for download from your website.

Since I had in the downloads folder on my machine v2.6.1, I could check on a "fresh install" that the instructions [2] work in v2.6.1 but fail in v2.6.3.2 .
I can of course continue to work in the older version, but I hope that this report may be useful anyway, or that a simple solution to work in the latest release exists.

Best,
Luca

cd models

tar -xvf BSM_gg_hh.tar

And inside the session:
import BSM_gg_hh
generate g g > h h
output test_folder
exit

Hi,

I believe that this bug is already fixed in our development version.
The problem is that your model was not following the UFO convention and therefore was not compatible with the latest optimization that we applied in the handling of the UFO model. I have de-activated such optimisation for fake UFO model.

Cheers,

Olivier

Hi Olivier,
that's great to hear, I will wait for the next release implementing this fix then.
Best,
Luca
