Hi,
I am having problems attempting to use the multiple outputs option implemented in TMVAMultiClass.C. I run this out of the box with:
root -l TMVAMulticlass.C(“MLP”)
and when the GUI pops up I click:
"(4a) Classifier Output Distributions (test sample)"
and I get:
root [1] — Opening root file TMVAMulticlass.root in read mode
— Found directory for method: MLP::MLP
: mva distribution not available (this is normal for Cut classifier)
: mva distribution not available (this is normal for Cut classifier)
: mva distribution not available (this is normal for Cut classifier)
: mva distribution not available (this is normal for Cut classifier)
Error: illegal pointer to class object (TH1*)hists.First() 0x0 2434 mvasMulticlass.C:79:
*** Interpreter error recovered ***
I am also interested in reading up on some documentation of the multiple outputs option, but unable to find it anywhere (the User’s Guide is apparently not up-to-date). If such documentation exists could someone please point me to it?
Thanks,
Ben
