HEPToolsInstallers always refreshing

Asked by Amin Aboubrahim on 2021-04-13

Hi Olivier,

I want to download the newest PY8 so I modified the HEPToolsInstallers.py file to look for the most recent version online, but I noticed that every time I run 'install pythia8', the HEPToolsInstallers gets replaced. Is this practice to prevent the download of the newest PY8 because it is not compatible with MG5aMC_PY8_interface?

Thank you,

If you run the install command we indeed starts by updating the package HepToolsInstaller to use the latest version of that tools.
This allows to be sure that all link/procedure are update and can be easily fixed in a central way.

They are indeed some problem with the latest version of PY8 (for matching) that prevent us to use the latest version of pythia8.
We have informed the pythia8 author of that isue but they did not came back to us on that point.
