problem with installing pythia-pgs and madgraph-pythia8 interface

Hi,

Is this for an installation on your laptop/personal desktop or within a cluster?

Can you access from that machine to this link?
http://madgraph.physics.illinois.edu/package_info.dat
and to this one
http://madgraph.phys.ucl.ac.be/package_info.dat

If you can,
1) did you have the environment variable MG5aMC_WWW defined?
2) what is your version of the "six" modules. old version of that module have sometimes issue with the "moves" category which is used here. Can you do the following within python3
import six
data = six.moves.urllib.request.urlopen('http://madgraph.physics.illinois.edu/package_info.dat")
print(data.getcode())

Cheers,

Olivier

Hi,
This is for installation on my desktop provided by the institute.
I can access both link , on clicking the link a page is opened on which below lines are written -

six module version 1.11.0

Since I am new to programming i face problem with the terms used -
Can you elaborate a bit what did you mean by defining enviromen variable MG5AMC_2.9.1.2

I ran the following command you said ,
when data = six.moves.urllib.request.urlopen("http://madgraph.physics.illinois.edu/package_info.dat") was done it gave some error i guess

>>> data = six.moves.urllib.request.urlopen("http://madgraph.physics.illinois.edu/package_info.dat")

During handling of the above exception, another exception occurred:

    raise URLError(err)

Sorry for being amateur ,please tolerate me for it

Ah you are running python3.6.
The fact that the code allows you to run with python3.6 is technically a bug since we have never tested it with python3.6
The official minimum version is python3.7 or later (or python2.7)

Can you try with a more recent version of python?

Cheers,

Olivier

when i do python -V in the terminal it shows
Python 2.7.17
Now again in python2 when i do date=..........
I am getting the same error
data = six.moves.urllib.request.urlopen("http://madgraph.physics.illinois.edu/package_info.dat")
Traceback (most recent call last):

    raise URLError(err)

just adding when i tried to import heft model ,again it says cannot connect to server , i guess it can be a problem of internet connection
import model heft
Error detected in "import model heft"
write debug file MG5_debug
If you need help with this issue please contact us on https://answers.launchpad.net/mg5amcnlo
str : Model not found locally and Impossible to connect any of us servers.
         Please check your internet connection or retry later

Looking at
https://stackoverflow.com/questions/57234628/socket-gaierror-errno-2-name-or-service-not-known-python

It seems that you have issue with your DNS which might not like python requesting an address resolution.
If you are on your campus network, then you might want to ask your sys-admin if they are limitation at the DNS level for such type of request.

One way to check is to test with
data = six.moves.urllib.request.urlopen('http://192.17.91.69/package_info.dat')
which bypass the DNS
