reweight module not enabling in version 2_5_0_beta2

[Ramkrishna]

Hi,

I am trying to enable the reweight module in MadGraph version 2_5_0_beta2 but I am not able to do so.

I tried to enter the two commands to do, without success. Below I am pasting the full output of it.

===============================================================
The following switches determine which programs are run:
/--------------------------------------------------------------------------------------------------\
| 1. Choose the shower/hadronization program: shower = Not installed |
| 2. Choose the detector simulation program: detector = Not installed |
| 3. Run an analysis package on the events generated: analysis = No analysis tool interfaced to MG5aMC.|
| 4. Decay particles with the MadSpin module: madspin = OFF |
| 5. Add weights to events for different model hypothesis: reweight = Not available (requires NumPy)|
\--------------------------------------------------------------------------------------------------/
  Either type the switch number (1 to 5) to change its setting,
  Set any switch explicitly (e.g. type 'madspin=ON' at the prompt)
  Type 'help' for the list of all valid option
  Type '0', 'auto', 'done' or just press enter when you are done.
 [0, auto, done, madspin=ON, madspin=OFF, madspin, parton, 3][60s to answer]
>5
5 not valid argument. Valid argument are in (auto,done,madspin=ON,madspin=OFF,madspin,parton,0,3).
please retry
>reweight = ON
reweight = ON not valid argument. Valid argument are in (auto,done,madspin=ON,madspin=OFF,madspin,parton,0,3).
please retry
>help
Here is the list of all valid options:
  auto
  done
  madspin=ON
  madspin=OFF
  madspin
  parton
  0
  3
Here is the list of command available:
  help

==========================================================

So, I see that reweight command is also not shown in the help command list. Is it a bug or I need to something else to enable the reweight cards. Also, I checked and see that NumPy is there which is required by the reweight module. So, I think it should not give me this.

Please suggest how I can fix this?

with regards,
Ram

As stated by the following toggle information:

reweight = Not available (requires NumPy)|

You must have installed numPy and f2py in order to have the reweight
functionality enabled. Is this the case?

Hi,

The problem is indeed that the code fail to find the f2py executable on your machine.
You can specify that path manually in the input/mg5_configuration.txt configuration file.

Cheers,

Olivier

Thanks Olivier & Valentin.

Yes, it was not working because on my cluster f2py is not there. It worked in my pc when I installed f2py.

A suggestion: In option 5 you should also mention about f2py. Like:

      5. Add weights to events for different model hypothesis: reweight = Not available (requires NumPy & f2py)

[Olivier Mattelaer (olivier-mattelaer)]

Hi,

f2py is technically part of numpy.
This is the reason why we mention numpy since this is the easiest way to install f2py.

Cheers,

Olivier

Hello,

As I have similar issue, I wanted to write below this topic although I am using different version of the Madgraph(MG5_aMc_v2_6_4) installed on my Mac. The issue is "reweight = Not available" and I cannot change it to "ON" mode. I have installed Numpy on my computer as well.

Any help is appreciated.

Hi,

Maybe numpy installed f2py to a weird location and that we are not able to find it.
Could you edit the configuration file (input/mg5_configuration.txt)
and replace the line
# f2py_compiler = None
by
f2py_compiler = XXXX
(where XXXX is the path to your f2py executable)

Cheers,

Olivier

Hi Olivier,

Seems I have control over the flag for Reweight now with your solution.

Thank you again!
