MadGraph 2.6.7 on Ubuntu 20

Asked by Francesca Acanfora

Hi,

I would like to use MadGraph 2.6.7 on Ubuntu 20.04.2 . Here the default python version is python 3, therefore I should launch MadGraph within virtualenvironment. I verified that virtualenvironment is working and added the MG5_aMC_v2_6_7 folder path to my PYTHONPATH variable. When in my terminal I launch ./bin/mg5_aMC I get the error

Traceback (most recent call last):
  File "./bin/mg5_aMC", line 129, in <module>
    import madgraph.interface.master_interface as interface
  File "/home/acanfora/MG5_aMC_v2_6_7/madgraph/interface/master_interface.py", line 43, in <module>
    import madgraph.interface.madgraph_interface as MGcmd

    import internal.file_writers as file_writers
ImportError: No module named internal.file_writers

What am I missing?

Hi,

Sorry but we do not provide support anymore for 2.6.7, neither for running MG5aMC with python2.

Cheers,

Olivier
