Hello ROOT & RooFit experts,
I’ve been having issues with pyROOT, running ROOT 6.22/02, python 3.6.8, and SL7.8. I’m not sure if the issue resulted from changes made in 6.22 or a previous version, the last root version I had installed where this was working was 6.16/04.
I have a program creating RooFit objects (RooRealVar, RooGenericPdf, RooArgList, RooAddPdf, and RooAbsReals) in a loop, and found that the memory usage of my program continued to rise with each loop iteration. What ultimately fixed this problem was issuing a:
object.Delete() del object
at the end of the loop for each created object. However, when I try issuing an
object.Delete() in 6.22/02, I get a segmentation fault error. Commenting out those lines, and just leaving in the
del object lines, I don’t get seg faults, but am back to the problem of large, growing memory usage.
I’m attempting to roll back to 6.16/04 now, but wanted to see if this was a known bug and if there are any other suggestions to try. Thanks!
