Exception: ['.//sps/atlas/g/goyc/MG5_aMC_v2_5_5/bin/PROC_sm_0/bin/internal/gen_jpeg-pl'] fails with no such file or di

In the title , the output directory is the standard one PROC_sm_0 ; I wanted to verify if it changed something

The path itself is correct.

When /sps/atlas/g/goyc/MG5_aMC_v2_5_5/bin/PROC_sm_0/bin/internal/gen_jpeg-pl
fails we try to recover by adding ./ since on some os it can help to recover (in presence of local path obviously)

So the wrong path is due to our recovery mecanism.

Can you try with the latest version of the code if this still occurs?

Cheers,

Olivier

I tried with the version 3 and I have the same error message

Command "output wz_ewk" interrupted with error:
Exception : ['.//sps/atlas/g/goyc/MG5_aMC_v3_0_0/bin/wz_ewk/bin/internal/gen_jpeg-pl'] fails with no such file or directory
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in 'MG5_debug'.
Please attach this file to your report

Can you copy paste the content of the debug file?

I will not bw able to look at it this week (not working on this project).
but a quick workaround should be to do
output XXXX -nojpeg
instead of
output XXXX

Cheers,

Olivier

I hope the format is readable enough :

Following your suggestion, I bumped into a similar issue

Command "output -nojpeg " interrupted in sub-command:
"output -nojpeg" with error:

So I wait until next week or so

Ok, then the problem is the lack of perl interpreter on your machine
(or a not compatible one)
Which version of perl do you have on your machine?

Cheers,

Olivier

Bonjour,

I am running on a main frame
It seems that the Perl version is V3.20

I tried to run at CERN - lxplus with the same issue.
 At CERN, the Perl version is v3.14_04

Regards, Corinne

I just ran into the same issue and I think I solved it.

The problem was that the source directory was synced between two machines but permissions were lost underway; so the perl script didn't have the x flag and couldn't be executed. Unfortunately, this was very painful to debug because you hide the actual error in madgraph.various.misc.call:

def call(arg, *args, **opt):
    """nice way to call an external program with nice error treatment"""
    try:
        return subprocess.call(arg, *args, **opt)
    except OSError:
        arg[0] = './%s' % arg[0]
        return subprocess.call(arg, *args, **opt)

This returned

Exception : ['.//MY_PATH/MadGraph/MG5_aMC_v2_6_5/bin/tmp/bin/internal/gen_cardhtml-pl'] fails with no such file or directory

which does not make any sense. To keep the proper exception in case the path-fix fails, I suggest to call the original one again:

def call(arg, *args, **opt):
    """nice way to call an external program with nice error treatment"""
    try:
        return subprocess.call(arg, *args, **opt)
    except OSError: # try if we find the file with relative path
        fix_arg = arg.copy()
        fix_arg[0] = './%s' % fix_arg[0]
        return subprocess.call(fix_arg, *args, **opt)
    except OSError: # give up and re-raise the original error
        return subprocess.call(arg, *args, **opt)

Hi,

Thanks for your findings/feedback.

Your proposed syntax is actually not valid but I see the idea.

 The problem here is that sometimes the first error stack is the one you want and sometimes, the second.
With Python3, both will be printed. So I think I will just wait for the python3 version of the code to be released in this particular case.

Cheers and thanks,

Olivier
