ommand "launch auto --only_generation" interrupted with error: ValueError : max() arg is an empty sequence

Asked by Bajarang on 2017-07-26

Dear Experts,

I am trying to generate p p > w+ [QCD] in MG5_aMC_v2_5_5
and to produce the grid files with ApplGrid 1.4.70 interfaced with amcfast-01-03-00

I am following the steps given here to produce the grids :
http://amcfast.hepforge.org/instructions.html

For the first preconditioning step, I set fixed_order=ON, iappl=1, passed proper lhapdf and things went smooth with no error.
I did not change anything in the FO_analyse_card.dat
The iterations set for grid formation are the default ones :
 5000 = npoints_FO_grid ! number of points to setup grids
 4 = niters_FO_grid ! number of iter. to setup grids
 10000 = npoints_FO ! number of points to compute Xsec
 6 = niters_FO ! number of iter. to compute Xsec

Problem occurs in the second step where we expect to fill the grids.
After >launch -o
and changing iappl=2 in the run_card I am getting this error :
Command "launch auto --only_generation" interrupted with error:
ValueError : max() arg is an empty sequence

Here is the full log file :

Dear Bajrang,

As written on the http://amcfast.hepforge.org/instructions.html webpage, you have to use a topdrawer or root analysis. The MG5_aMC default is HwU format, which is not compatible with applgrid/aMCfast. Hence, you have to write a topdrawer or root analysis and specify that in the FO_analyse_card. There are several examples of analysis available in the FixedOrderAnalysis directory, that should help you write your own.

best,
Rikkert

Dear Bajrang,

Your problems with ROOT seem to be a compilation/linking problem which depends rather specifically on your installation of ROOT. It will be difficult to help you debugging with that.

For the topdrawer one, what does the log.txt file say? There should be one in the
/home/rohit/Downloads/MG5_aMC_v2_3_3/bin/pp_wplus_qcd_top/SubProcesses/P0_dxu_wp/all_G1/
directory. If it doesn't say anything in particular, what is the error message if you, from within that directory, executes
../madevent_mintFO < input_app.txt

Best,
Rikkert

Dear Rikkert,

For the topdrawer case, the /home/rohit/Downloads/MG5_aMC_v2_3_3/bin/pp_wplus_qcd_top/SubProcesses/P0_dxu_wp/all_G1/log.txt does not say anything specific to the error.

Dear Bajrang,

I've forwarded your message to Valerio Bertone. He might be able to help you better than I do.

best,
Rikkert

Dear Bajrang,

I suspect that this might be a memory issue.
The question is that the default (x,Q2) grid allocated by aMCfast is quite large and in some cases it may cause a memory overflow.
If this is the problem, it can be fixed by reducing the size of this grid.
To do so, you just have to comment in the lines:

c*
c* aMCfast common.
c* Needed to redefine the grid parameters
c*
c include "reweight_appl.inc"
c include "appl_common.inc"
c*
c* Grid parameters
c*
c appl_Q2min = 2500d0
c appl_Q2max = 40000d0
c appl_xmin = 2d-7
c appl_xmax = 1d0
c appl_nQ2 = 10
c appl_Q2order = 3
c appl_nx = 50
c appl_xorder = 3

in the analysis_begin subroutine of your analysis file.
To start with, I would use something like:

      appl_Q2min = 2500d0
      appl_Q2max = 40000d0
      appl_xmin = 1d-5
      appl_xmax = 1d0
      appl_nQ2 = 10
      appl_Q2order = 3
      appl_nx = 20
      appl_xorder = 3

that is a significantly smaller grid as compared to the default one.
If this this woks bit does not meet your accuracy requirements, you can try to increase it until the code does not crush.

If you change the grid, you need to restart the production from scratch, meaning that you need to redo step 1.
Also notice that if req_acc_FO in your run card is not equal to -1 (as it seems to be your case) the parameters:

 5000 = npoints_FO_grid ! number of points to setup grids
 4 = niters_FO_grid ! number of iter. to setup grids
 10000 = npoints_FO ! number of points to compute Xsec
 6 = niters_FO ! number of iter. to compute Xsec

will be ignored.
I general, I find that it is a better idea to use the target accuracy req_acc_FO rather than setting the number of iterations.
Let us know if this solves the problem.

Best regards,
Valerio

Dear Valerio,

thanks for your reply. I tried to change the grid size as per your
suggesions with req_acc_FO set to -1 and changing the grid parameters
as below[1].

I tried running it with both the options root and topdrawer.
I still get the error but it is different this time.
Can you please take a look at it. For error with root [2] and
for error with topdrawer [3]

For root I guess something is wrong with the fortran code, which I just copied from the example code given on amcfast site commenting out only the grid related part and changing the values accordingly. It will be really helpful if you give some hints about this fortran code's usage etc.

Also another thing I want to ask is :
while running with root, I chose this combination in FO_analyse_card.dat :
FO_ANALYSIS_FORMAT = root
FO_EXTRALIBS = Core Cint Hist Matrix MathCore RIO dl Thread
FO_EXTRAPATHS = /home/bajarang/packages/myroot/root/lib
FO_INCLUDEPATHS = /home/bajarang/packages/myroot/root/include
FO_ANALYSE = analysis_root_pp_V.o
I want to know if these options are correct, or I have to include/exclude anything.
Thanks for your patience.

Regards,
Bajrang

Dear Bajrang,

you also have to comment in the lines:

c*
c* aMCfast common.
c* Needed to redefine the grid parameters
c*
c include "reweight_appl.inc"
c include "appl_common.inc"
c*
c* Grid parameters
c*

otherwise you're trying to use undeclared variables.

As for req_acc_FO I meant exactly the contrary: I find it better to set it to some value (different from -1) as your were doing before.
In particular, in my experience, I find that req_acc_FO = 0.01 is good enough for the first step (iappl = 1), while something like req_acc_FO = 0.001 is a good compromise for the second step (iappl = 2).
Let me know if this helps.

Best regards,
Valerio

Bajarang (bajjubaba) said : #9

Dear Valerio,

Thanks for your quick reply. I completely misunderstood your earlier comment about setting req_acc_FO. Now I set it back to 0.01. I commented out the include files and again tried with both formats with FO_ANALYSIS_FORMAT = root, no luck, the include files errors did disappear but the final error still perstists.

with FO_ANALYSIS_FORMAT = topdrawer, it executed the commands and tried to save the output but maybe there is something wrong with my root (expecting your comment) as I am getting below error now. Let me try to debug that from my side, but your comments will really help in knowing what is wrong exactly. Thanks in advance.

Dear Bajrang,

could you please check whether the grids:

 /home/bajarang/packages/MG5_aMC_v2_5_5/bin/pp_wplus_qcd_top/SubProcesses/P0_udx_wp/all_G1/grid_obs_0_out.root
 /home/bajarang/packages/MG5_aMC_v2_5_5/bin/pp_wplus_qcd_top/SubProcesses/P0_dxu_wp/all_G1/grid_obs_0_out.root

actually exist? And if they do, if their combination:

output to: /home/bajarang/packages/MG5_aMC_v2_5_5/bin/pp_wplus_qcd_top/Events/run_01/aMCfast_obs_0_starting_grid.root

is there?
The problem might be related to APPLgrid because it looks like the code stop when trying to read the grids.
Maybe you installed it linking a different version of ROOT?

Valerio

Dear Valerio,

You are right, the applgrid was configured with some different version of root. I fixed it and now the grids are getting produced with topdrawer option.

Thank you so much.

Bajrang

Thanks Valerio Bertone, that solved my question.
