                                                                   -> pip install numpy

Im launching it using the command-> ./maddm.py

Traceback (most recent call last):

Can you show the content of the directory
/home/raseeb/MG5_aMC_v2_9_6/PLUGIN/maddm/

The important point is to check if the file maddm_interface.py does exists.
if not, then I would suggest to redo the installation of the maddm plugin

Cheers,

Olivier

It does exist in the directory:-

raseeb@raseeb:~/MG5_aMC_v2_9_6/PLUGIN/maddm$ ls
auxiliary.py Fermi_line_likelihoods maddm_interface.py README

Then I assign Daniele,

Who might know if they are incompatibility between 2.9.6 and maddm

Hi Raseeb,

I suspect your issue could be linked to the python version. Are you sure you are using Python 2.7?
I can reproduce your problem only if I try to run the latest version of MadDM on top of version 2.9.10 of MadGraph with Python 3 instead of Python 2.

If you run with ./maddm.py likely you're using system Python which for sure is Python 3 and so your error.
Try to install Python 2 and run with:
python2 maddm.py
from inside <Madgraph_folder>/bin directory.

Let me know.

Cheers.

PS. We are very close to release a Python 3 MadDM.

Hi Daniele,

If I check my python version it comes out to be 2.7.18

raseeb@raseeb:~/MG5_aMC_v2_9_6/bin$ python2 --version
Python 2.7.18

When I use the command "python2 maddam.py" I get the following error :-

raseeb@raseeb:~/MG5_aMC_v2_9_6/bin$ python2 maddm.py
madgraph requires the six module. The easiest way to install it is to run "pip install six --user"
in case of problem with pip, you can download the file at https://pypi.org/project/six/ . It has a single python file that you just need to put inside a directory of your $PYTHONPATH environment variable.

Then using the recommended command tell me the package is already downloaded.

raseeb@raseeb:~/MG5_aMC_v2_9_6/bin$ pip install six --user
Requirement already satisfied: six in /usr/lib/python3/dist-packages (1.16.0)

It gives me the same error again when I try launch using the "python2 maddam.py" command.

Regards,
Raseeb

Because your default pip is not for Python 2.7.18
so in this case you need to do pip2 install six --user
