IOSvc.Input property can't be set from CLI

[m-fila]

I cannot pass to k4run the input files to process via --IOSvc.input blah.root. On the other hand IOSvc.output foo.root works like a charm. The difference between the two is that output is a string property while input is a vector property, so the problem seems to be in IOSvc parsing of vector<..>. Is there a special syntax to be used in the CLI that I am unaware of or is it a parsing problem in IOSvc?

The IOSvc.Input is not listed in the acceptable arguments (unless it's assigned in a steering file):

  --IOSvc.OutputLevel [IOSVC.OUTPUTLEVEL], --OutputLevel.IOSvc [IOSVC.OUTPUTLEVEL]
                        output level [Service]
  --IOSvc.output [IOSVC.OUTPUT], --output.IOSvc [IOSVC.OUTPUT]
                        List of files to write output to [IOSvc]
  --IOSvc.Output [IOSVC.OUTPUT], --Output.IOSvc [IOSVC.OUTPUT]
                        List of files to write output to [IOSvc]
  --IOSvc.outputCommands IOSVC.OUTPUTCOMMANDS [IOSVC.OUTPUTCOMMANDS ...], --outputCommands.IOSvc IOSVC.OUTPUTCOMMANDS [IOSVC.OUTPUTCOMMANDS ...]
                        A set of commands to declare which collections to keep or drop. [IOSvc]
  --IOSvc.IOType [IOSVC.IOTYPE], --IOType.IOSvc [IOSVC.IOTYPE]
                        Type of input file (ROOT, RNTuple) [IOSvc]
  --IOSvc.ImportedFromk4FWCore [IOSVC.IMPORTEDFROMK4FWCORE], --ImportedFromk4FWCore.IOSvc [IOSVC.IMPORTEDFROMK4FWCORE]
                        This is set to true when IOSvc is imported from k4FWCore instead of Configurables in python [IOSvc]
  --IOSvc.FirstEventEntry [IOSVC.FIRSTEVENTENTRY], --FirstEventEntry.IOSvc [IOSVC.FIRSTEVENTENTRY]
                        First event entry to read [IOSvc]

I'm not sure if the problem here is that it's a vector of string because outputCommands are also vector of strings and they appear here just fine. Could it be something with the python wrappers (IOSvc.py, ApplicationMgr.py?)?

This will be fixed tomorrow in the nightlies @giovannimarchiori. Passing IOSvc.Input file1.root or IOSvc.Input file1.root file2.root to read multiple files will be possible.

Hi @jmcarcell ,
thanks a lot! Does this require some update in other packages other than k4FWCore? I tried syncing my fork of k4FWCore and pulling these changes (plus making a clean build) and the code does not work:

• if the Input property of the iosvc service is defined in blah.py, doing k4run blah.py IOSvc.Input foo.root just ignores the CLI option
• if I unset the input property of the iosvc service in blah.py and run again, I get the following error:

IOSvc               ERROR Property::fromString   Cannot convert '[['r', 'o', 'o', 't', '/', 'a', 'l', 'l', 'e', 'g', 'r', 'o', '_', 'v', '0', '3', '_', 'e', 'v', 't', 's', '_', '1', '0', '_', 'p', 'd', 'g', '_', '2', '2', '_', 'M', 'o', 'm', 'e', 'n', 't', 'u', 'm', 'M', 'i', 'n', 'M', 'a', 'x', '_', '2', '0', '_', '2', '0', '_', 'G', 'e', 'V', '_', 'T', 'h', 'e', 't', 'a', 'M', 'i', 'n', 'M', 'a', 'x', '_', '9', '0', '_', '9', '0', '_', 'P', 'h', 'i', 'M', 'i', 'n', 'M', 'a', 'x', '_', '1', '.', '5', '7', '0', '7', '9', '6', '_', '1', '.', '5', '7', '0', '7', '9', '6', '_', 's', 'i', 'm', '.', 'r', 'o', 'o', 't']]' for property 'Input' in class 'IOSvc': std::invalid_argument, cannot parse '[['r', 'o', 'o', 't', '/', 'a', 'l', 'l', 'e', 'g', 'r', 'o', '_', 'v', '0', '3', '_', 'e', 'v', 't', 's', '_', '1', '0', '_', 'p', 'd', 'g', '_', '2', '2', '_', 'M', 'o', 'm', 'e', 'n', 't', 'u', 'm', 'M', 'i', 'n', 'M', 'a', 'x', '_', '2', '0', '_', '2', '0', '_', 'G', 'e', 'V', '_', 'T', 'h', 'e', 't', 'a', 'M', 'i', 'n', 'M', 'a', 'x', '_', '9', '0', '_', '9', '0', '_', 'P', 'h', 'i', 'M', 'i', 'n', 'M', 'a', 'x', '_', '1', '.', '5', '7', '0', '7', '9', '6', '_', '1', '.', '5', '7', '0', '7', '9', '6', '_', 's', 'i', 'm', '.', 'r', 'o', 'o', 't']]' to std::vector<std::string,std::allocator<std::string> >  StatusCode=FAILURE

Only k4FWCore, and that's weird, I can run it fine with multiple files or overriding the file from the CLI. Did you use k4_local_repo? which k4run should correctly point to the local version. How are you passing the arguments?

[giovannimarchiori]

I am setting up the working area like this:

git clone [email protected]:HEP-FCC/FCC-config.git
git clone [email protected]:key4hep/k4FWCore.git
git clone [email protected]:key4hep/k4geo.git
git clone [email protected]:HEP-FCC/k4RecCalorimeter.git

I setup the environment with

source /cvmfs/sw-nightlies.hsf.org/key4hep/setup.sh
cd k4RecCalorimeter && k4_local_repo && cd ..
cd k4geo && k4_local_repo && cd ..
cd k4FWCore && k4_local_repo && cd ..

I compile all packages

I run with something like

k4run python/allegro_v03_evts_10_pdg_22_MomentumMinMax_20_20_GeV_ThetaMinMax_90_90_PhiMinMax_1.570796_1.570796_HCal_ON_digi_reco.py --IOSvc.Input root/allegro_v03_evts_10_pdg_22_MomentumMinMax_20_20_GeV_ThetaMinMax_90_90_PhiMinMax_1.570796_1.570796_sim.root --IOSvc.Output root/allegro_v03_evts_10_pdg_22_MomentumMinMax_20_20_GeV_ThetaMinMax_90_90_PhiMinMax_1.570796_1.570796_HCal_ON_digi_reco.root > log/allegro_v03_evts_10_pdg_22_MomentumMinMax_20_20_GeV_ThetaMinMax_90_90_PhiMinMax_1.570796_1.570796_HCal_ON_reco.log

where the steering script contains:

...
from k4FWCore import IOSvc
from Configurables import EventDataSvc
io_svc = IOSvc("IOSvc")
io_svc.Input = inputfile
io_svc.Output = outputfile
ExtSvc += [EventDataSvc("EventDataSvc")]
...

from k4FWCore import ApplicationMgr
applicationMgr = ApplicationMgr(
    TopAlg=TopAlg,
    EvtSel='NONE',
    EvtMax=Nevts,
    ExtSvc=ExtSvc,
    StopOnSignal=True,
)

I am quite lost...
now the script seems to work, but a similar one fails with the same errors...
working script: https://gitlab.cern.ch/gmarchio/FCC-scripts/-/blob/main/run_ALLEGRO_reco.py?ref_type=heads

To me IOSvc is configured the same way in the two scripts.

That should be fixed in #243.
