ValueError when generating events

Asked by Wei Shi on 2018-06-20

Dear experts,

I ran into the "could not convert string to float" error in [1] when generating events. The event generation set up is in [2] where the error in [1] could be reproduced.

It suggests me attach the "ME5_debug" file. But I check many directories and fail to find this file.

From some old thread, it seems related to flavor setting in the run_card. But I am not sure. Would you take a look? How should I resolve this?

Thanks much,
Wei

Could you just send me the proc_card.dat?

The ME5_debug file should normally be written in your local directory from where you submit the job.
This is typically a symlink that point to another debug file.

Hi Olivier,

I have another student try the setup and it's fine. Could you check your public key is attached to your account [1]? This is the repo[2] it's cloning.

All the cards are here[3]. In this case, I can do it interactively in MG5; the problem happens when I am using this script[4] to create a tarball for massive events generation needed by the central MC team. So there could be some contradictory settings I am not aware.

I couldn't find the ME5_debug symlink. Is it supposed to be in some folder in the MG package?

Cheers,
Wei
