Release 22 and Python 3

As you might know, Release 22 is coming, and with it Python3. This will bring some advantages for us, as newer MadGraph versions (and functionality) only support Python3. The external MadGraph models, however, are generally not Python3 compatible.

We’ve taken care of updating all the models to be Python3 compatible with this merge request:
https://gitlab.cern.ch/atlas-generators-team/MadGraphModels/-/merge_requests/123

We’ve done some simple checks to be sure that models can be loaded in both Python2 (e.g. release 21.6.X) and Python3 (e.g. release 22.0.X), but have not checked the physics output. We believe this is a technical update that should not have an impact on physics. Note that the normal SUSY model MSSM_SLHA2 is bundled with MG itself, so is unaffected (this only affects e.g. RPV models).

If you’d like to test your model, you can check out the branch (the button “Check out branch” in git will give you instructions), point your PYTHONPATH at it, and run your favorite job. When you import your model MadGraph should show you the full path from which it loads the model, in case you aren’t sure if the new version is being picked up.

The plan is to push this merge request at noon CERN time on Tuesday, June 15th. It will take a few hours to propagate to cvmfs, but after that we will have the new versions in production everywhere. If you identify any problems during that period, please let me/us know as quickly as possible. If needed, we will be able to quickly revert the change.

Keeping the repository together, rather than branching, saves us quite a lot of maintenance effort, so we thank you for your understanding.
