Re: [HTCondor-users] No output file with pyROOT, using RECREATE

[lalloue@xxxxxxxxxxxxx]

Hi Romain,

Thank you very much for the answer!

When I add this line (without the quotes):

transfer_output_files = OutFile.root

I have the following result:

error reading from /pool/condor/dir_*/OutFile.root: (errno 2) No such file or directory; SHADOW failed to receive file(s) from ...

Yet, I'm sure that my pyROOT script creates a file named "OutFile.root".

Maybe the ROOT files created with the "RECREATE" option are not detected by HTCondor?

Best regards,

Nathan Lalloué

Hi Nathan, 

I think you are missing transfer_output_files, put in your condor submit file both lines below:

transfer_output_files = "OutFile.root"

transfer_output_remap = "OutFile.root = myName_$(Process).root"

Because the first line tells condor the name of the output file and the second tells condor to remap it.

I hope it will work,

Best regards,

Romain Bouquet

Dear HTCondor community,

I am trying to run a script in python that makes use of ROOT, named "my_code.py" here.
This code reads the ROOT input file and creates an other one from it, named "OutFile.root", with the following line:

OutFile = ROOT.TFile("OutFile.root", "RECREATE")

Then, I run this script with HTCondor, with the following submit description file:

executable              = my_code.py
arguments               = $(myfile)
output                  = output/job.$(ClusterId).$(ProcId).out
error                   = error/job.$(ClusterId).$(ProcId).err
log                     = log/job.$(ClusterId).log
transfer_input_files    = $(myfile)
transfer_output_remaps  = "OutFile.root = myName_$(Process).root"
queue myfile matching *.root

I don't have any apparent error, but when I check in my submit directory, no file is created.
Could you please tell me what I am doing in a wrong way?

Thank you very much in advance.

Best regards,

Nathan
