I’m blurring a simulated dataset with a gaussian, and that all works well, but the issue is that there doesn’t seem to be a way to stop the terminal messages. This happens in the line
RooFFTConvPdf simConvPdf(“simConvPdf”, “simConvPdf”, ene, simHistPdf, gauss);
which leads to a terminal output of:
[#1] INFO:Eval – RooRealVar::setRange(ene) new range named ‘refrange_fft_simConvPdf’ created with bounds [0,10]
[#1] INFO:Caching – RooAbsCachedPdf::getCache(simConvPdf) creating new cache 0x7fd956d7c510 with pdf simHistPdf_CONV_gauss_CACHE_Obs[ene]_NORM_ene for nset (ene) with code 0
I am doing a minimization that uses the process, so this creates a slowdown. Is there a way to set the verbosity to quiet?
Dear @nicconflo ,
Probably @jonas or @moneta can be of help here.
Hi @nicconflo, welcome to the ROOT forum!
The verbosity of RooFit classes can be controlled with the RooMsgService class. There is also a tutorial on how to use it in C++ and Python:
This line from the tutorial is quite useful to inspect what is currently printed:
You will get this output by default:
Active Message streams
 MinLevel = PROGRESS Topic = Generation Minimization Plotting Fitting Integration LinkStateMgmt Eval Caching Optimization ObjectHandling InputArguments Tracing Contents DataHandling NumericIntegration FastEvaluations
 MinLevel = INFO Topic = Minimization Plotting Fitting Eval Caching ObjectHandling InputArguments DataHandling NumericIntegration
 MinLevel = INFO Topic = HistFactory
So you see that your
INFO messages are printed by the message stream
, as this one covers the
Caching topics. To get rid of the info messages, I suggest changing the minimum level of that stream to
RooMsgService::instance().getStream(1).minLevel = RooFit::WARNING;
I hope this helps!
That worked perfectly. Thank you!
