A question regarding mg5 shell

Asked by Disha Bhatia


I have a very simple question. I have installed madgraph in my cluster.
However when I do ./bin/mg5_aMC and enter the madgraph shell,
some of the keys of keyboard are not functioning well.

For example the arrow keys give output as: ^[[A^[[A^[[A

and tab also doesnt function well.

This is only happening inside the madgraph environment and not the linux terminal.

I would be really glad if you could let me know how to improve this.

Likely the issue is the readline module of python.
Could you check if that module is correctly installed for the version of python that you are using?

I have seen the issue on some centos7 machine (but not all of them) but I have not investigate enough time on it so I do not know how to fix it.

Thanks a lot for the suggestion.

I installed a madgraph which was compatible with python 2.7 and now I don't have this problem.

Thank you very much,
