Hi Olivier,
this is fixed with properly setting LIBRARY_PATH. So now it is running.
Can you please comment on few more questions:

1) Could you please confirm that I am trying to run Kamikaze reweighting in a correct way?

2) In the instructions about the reweighting the "keep_rwgt_info" parameter is mentioned. Can you please point me to where this parameter is set? I do not see this parameter in the cards.. Is this parameter False by default (Kamikaze reweighting is the default)?

Greetings,
Senka

In 2.3.3 only kamikaze re-weighting is available.
Therefore the parameter keep_rwgt_info is not present in the run_card.

Now I do not see your reweight_card but from the log this sounds reasonable.

Cheers,

Olivier

Hi Olivier,
in my reweight_card I just have a list of point:

launch
   set Dim6 1 5
   set Dim6 2 0
   set Dim6 3 0
launch
   set Dim6 1 0
   set Dim6 2 0
   set Dim6 3 100
launch
   set Dim6 1 0
   set Dim6 2 0
   set Dim6 3 0

and in my parameter file I have:

Block dim6
    1 3.000000e+00 # CWWWL2
    2 6.000000e+00 # CWL2
    3 1.500000e+02 # CBL2

Thank you!

Senka

That's good.

Cheers,

Olivier

Hi Senka, Olivier,
  Im having exactly the same problem. Could you tell me exactly what you did with LD_LIBRARY_PATH to fix
the issue? Just adding the path to the python2.7 libs didn't work for me.

Regards,
   James.

Hi James,
I just did:

export LIBRARY_PATH=$LD_LIBRARY_PATH

Senka

Many thanks! That solved it,
   James.
