ImportError : No module named allmatrix2py

Asked by Roberto Franceschini on 2020-09-10

I am trying reweghting cards according to the pp>e+e- example
https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/Reweight#ppee-cross-section
I am 2.7.2 and the generation of events is fine but the reweighting is not going through
```
Command "generate_events run_01" interrupted with error:
ImportError : No module named allmatrix2py
Please report this bug on https://bugs.launchpad.net/mg5amcnlo

Please attach this file to your report.

This module does not exist and I cannot import it from python 2.7.5 ipython console. I have tried to install it but is not on pip, should I find it somewhere in the MG5 source?

The only seemingly relevant file I can find are
./ReweightTest/rw_me/SubProcesses/allmatrix2py.cpython-37m-x86_64-linux-gnu.so
./ReweightTest/rw_me/SubProcesses/allmatrix3py.cpython-37m-x86_64-linux-gnu.so
but I am not sure it is the one intended to be imported.

It it probably worth mentioning that in MG 2.6.0 I do not get this module-related error. I just tried it out and it gets stuck, but with no errors.
It just stays for indefinitely on

HI Roberto,

This is a python module which is created by madgraph on the flight.
So this one is related to your UFO model and process that you are using.
So indeed this is not installable via pip.

> ./ReweightTest/rw_me/SubProcesses/allmatrix2py.cpython-37m-x86_64-linux-gnu.so
> ./ReweightTest/rw_me/SubProcesses/allmatrix3py.cpython-37m-x86_64-linux-gnu.so

This is indeed the library that we need to load as a python module.
However this library was created for python3.7 and since you are stating that you used MG5aMC,
you likely need to create it for python2.7 (or python2.6).

This likely means that your version of "f2py" by default is the one of python3 and not the one of python2.
The easiest fix is to go to 2.8.0 where we support (and this is the default) python3.
Otherwise you will need to specify the path to f2py executable related to python2.

Cheers,

Olivier

Hello! thanks for looking into this!

I have tried 2.8.0 and still complains, about something else.

Command "generate_events run_01" interrupted with error:
ModuleNotFoundError : No module named 'P1_uux_epem2py'
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in
'/home/roberto/cernbox/Clusters/MG5_aMC_v2_8_0/ReweightTest/run_01_tag_1_debug.log'.
Please attach this file to your report.

I have done some tests with 2_7_2 as well by adding the path to f2py, but
that too sitll does not work. Maybe better if we focus on having 2.8.0 work?

What happens if you do

cd /home/roberto/cernbox/Clusters/MG5_aMC_v2_8_0/ReweightTest/rw_me/SubProcesses/
make allmatrix2py.so
ls
f2py --version
python3
import allmatrix2py
