store_entry() failed when running scan

Asked by Kai-Feng Chen

Hi,

I am using Madgraph 2.7.2 to calculate the cross-section of a simple process with a BSM model I defined. I am using the scan feature to scan the mass of my new particles, but after the cross-section has been calculated, it reported an error as follow before moving into a second run:
'''
  === Results Summary for run: run_02 tag: tag_1 ===

     Cross-section : 0.9156 +- 0.001447 pb

The python error in the log file is:

I think this store_entry() function should be an internal function, so I wonder whether this is a bug or it is me that make some mistakes. Thanks in advance for your answer!

Hi,

I do not reproduce the error, and can not see how such error is possible.
My guess is either that your version 2.7.2 is corrupted (or you are not in 2.7.2).

You can check in the file
models/check_param_card.py
around line 984 you should have the line like
    def store_entry(self, run_name, cross, error=None, param_card_path=None):

If you do not have the "param_card_path=" then you are either not in 2.7.2 or your version is corrupted.
IF this is fine on your side, I will need the full debug file in order to try to reproduce it. (in that case, you need to convert this to a bug report in order to attach the file)

Cheers,

Olivier

Hi,

Many thanks for pointing out where that function lies in. Indeed in my check_param_card.py, the function store_entry() does not have that param_card_path argument. I am indeed using 2.7.2 so I think somehow my version is corrupted. Many thanks for helping me resolve this issue!

Kai-Feng
