Problem installing mg5amc_py8_interface

You can try to download the pythia82.tgz tarball by hand and then install
pythia8 with MG5aMC using the command:

./bin/mg5 --pythia8_tarball=<path_to_your_locally_downloaded_tarball>

It would be nice to understand why the script './get_pythia8_version.py
../pythia8' fails. So before trying the above, I suggest you go to the
directory:

/sb/home/kayskh/MG5_aMC_v2_5_1/HEPTools/MG5aMC_PY8_interface

and try to compile by hand the interface with

./compile.py <path_to_pythia8_installation_prefix>

This should reproduce the same error you faced when installing the
interface directly with MG5aMC but this time you can add debug statement in
compile.py and get_pythia8_version.py.

Let me know,

Hi Valentin,

Thanks for your answer.

Trying to compile by MG5aMC_PY8_interface hand, I obtain now a different error:

Error in MG5aMC_PY8_interface installer. Could not find file:
   /sb/home/kayskh/MG5_aMC_v2_5_1/HEPTools/pythia8/share/Pythia8/examples/Makefile.inc

In fact the directory /sb/home/kayskh/MG5_aMC_v2_5_1/HEPTools/pythia8/share/Pythia8/examples itself doesn't exist.

Installing pythia8 with the command you suggested, I get the error message "mg5_aMC: error: no such option: --pythia8_tarball".

Jake

Hi Valentin,

I created the directory /sb/home/kayskh/MG5_aMC_v2_5_1/HEPTools/pythia8/share/Pythia8/examples by hand and copied into it Makefile and Makefile.inc from /sb/home/kayskh/MG5_aMC_v2_5_1/HEPTools/pythia8/ . Trying to install the interface again, I now obtain the error

A problem occured during the installation of 'mg5amc_py8_interface'.
Content of the installation log file '/sb/home/kayskh/MG5_aMC_v2_5_1/HEPTools/MG5aMC_PY8_interface/mg5amc_py8_interface_install.log':

This is necessary for the default compilation of MG5aMC_PY8_interface.
You can try again with the option --pythia8_makefile but HEPMC2 will need to be available at runtime.

Command "install mg5amc_py8_interface " interrupted in sub-command:

I tried implementing the modification of <MG5_install_path>/madgraph/interface/madgraph_interface.py in comment 3 of https://bugs.launchpad.net/mg5amcnlo/+bug/1650664 but the problem persists.

Jake

Hi Jake,

Could you try with the latest version 2.5.2; there you should be able to
use the option
'--pythia8_tarball=<path_to_your_locally_downloaded_PY8_tarball>'.
Also this might resolve the HEPMC problem, since I now force the local
installation of hepmc with MG5aMC, which guarantees to have a static
library.

Hi Valentin,

Both problems persist when I try with 2.5.2.

Jake

So in v2.5.2 when you do:

./bin/mg5
MG5_aMC>install hepmc

it goes through but you are saying that you don't have any static library
in:

<MG5_install_path>/HEPTools/hepmc/lib/libHepMC.a

correct?

And for pythia8, you are saying that you cannot manage to download the
pythia8 tarball automatically with 'install pythia8' and specifying it's
local path with somehting like

./bin/mg5
MG5_aMC>install pythia8
--pythia8_tarball=/Users/valentin/Downloads/pythia82.tgz

fails because the option '--pythia8_tarball' is not recognized?

This is very weird since I cannot reproduce any of the above two problems
(especially not the second one which should not be environment dependent).

Could you please let me know the details of your system then?

> OS and its version
> Python interpreter version
> GCC ompiler suite

Sorry that these installations seem to cause so much problems.

The pythia8_tarball option worked. The problem was simply that I was using it as an option at MadGraph startup instead of as an option when running install within MadGraph (it worked even in 2.5.1). Once Pythia8 was automatically installed mg5_py8_interface installed with no further problems.

Thanks a lot for your assistance and patience.

Jake

Dear Valentin,

I encountered a very similar problem as Jake had sometime ago. Here it is;

I am on OpenSuse Leap15, I've got MG5_2_6_3_2 and Root_v6_14_02 installed.

I am trying to install pythia with the command; install pythia,

it successfully installs LHAPDF6, HEPMC but when it comes to pythia it throws following warnings and errors;

|| /!\/!\/!\
|| Note that he following version of HEPMC
|| /home/alper/softwares/MG5_aMC_v2_6_3_2/HEPTools/hepmc
|| was detected as *not* supporting named weights. The MG5aMC-PY8 interface will have to write a separate hepmc file
|| for each extra weight potentially specified for studying systematic uncertainties (PDF, scale, merging, etc...)
We recommend that you change to the version of hepmc to the one that can be installed with this tool
|| /!\/!\/!\

installs pythia and in installing the interface it says;

A problem occured during the installation of 'mg5amc_py8_interface'.
Content of the installation log file '/home/alper/softwares/MG5_aMC_v2_6_3_2/HEPTools/MG5aMC_PY8_interface/mg5amc_py8_interface_install.log':

This is necessary for the default compilation of MG5aMC_PY8_interface.
You can try again with the option --pythia8_makefile but HEPMC2 will need to be available at runtime.

and terminates the installation.

Looking forward for your response,

Thanks.

And when I typed this;

MG5_aMC_v2_6_3_2/HEPTools/MG5aMC_PY8_interface >./compile.py ../pythia8 --pythia8_makefile

I got following error;

------------------------------------------------
MG5aMC_PY8_interface compilation output log:
Error: main89 requires HEPMC2

------------------------------------------------
Error during the compilation of MG5aMC_PY8_interface:
Error: main89 requires HEPMC2

Dear Valentin,

I am still having the problem I mentioned in previous thread. MG5aMC_PY8_interface can not be installed with install command.

Looking forward for your answer.

Thanks.

Dear A. Hayreter,

I had exactly the same problem on openSuSE (15.1).

The compilation of hepmc puts the generated libraries in the path
HEPTools/hepmc/lib64/ .
But the compilation of pythia8 searches them in the path HEPTools/hepmc/lib/ (not lib64).

My workaround is:
(1) in bin/MG5_aMC "install hepmc"
(2) create a softlink from lib to lib64 in HEPTools/hepmc/
(3) in bin/MG5_aMC "install pythia8"

If there is a better way to insert changes into the higlhly automated installation", I'd be interested.
I've not figured out, what causes "libdir" of "hepmc" to be set to "lib64" in openSuSE.

Hi,

I have try to implement the fix. Could you try?
Should be working at 10h45 (in 30 min)

Cheers,

Olivier

This works. Many thanks for the fix, Olivier!

Sidenote: On this openSuSE release, the environment-variable $CONFIG_SITE is set by default for all login-shells. This variable is evaluated by "configure" of hepmc2. $CONFIG_SITE points to a script that sets the value of "$libdir", in my case
    libdir='${exec_prefix}/lib64'
This determines the final location of the libraries.

Hi,
I have installed pythia8245 via
MG5_aMC>install pithier --pythia8_tarball=/Users/vahid/Downloads/pythia8245.tar
and it is successful but when I try

Looking forward for your answer.

thanks

The plugin indeed requires to have pythia83.
The reason is that pythia83 and pythia82 does not support the same API for the userhook.
And therefore we have switch everything to be working with pythia83.

Now if you use bazaar (or breezy) you can create an older version of the plugin which is pythia82 compatible.
But I'm not sure that even with that you will have full compatibility with pythia82.

Cheers,

Olivier

Hi Olivier,
Many thanks to the response
I have installed pythia8306 and the problem solved.
