Hi,
I discovered that when making a RooDataSet with around 83M entries in Roofit v3.50, I get the following output
Filling the RooDataSet for SingleMuon.root… Number of files: 1
Number of entries: 83183208
terminate called after throwing an instance of 'std::bad_alloc’
what(): std::bad_alloc
however, when running with version 3.14 or 3.17, this does not happen.
Filling the RooDataSet for HISingleMuon.root… Number of files: 1
Number of entries: 83183208
returning raw dataset…
RooDataSet::HISingleMuonHP_21Jan.root[muonPt,muonEta,muonScat,muonELoss,muonCategory,chargeCategory,centrality,massCB] = 16811320 entries
does anyone know how to work around this?
