Hi,

I have a ROOT macro for analysis of simulation data written in cpp. I produce a number of TH1s and TH2s, which I’d like to explore using PCA and other techniques more easily accessible to me using python. I understand I could write a pyROOT script to produce all my plots in python anyway, but before I rewrite my analysis unnecessarily, I’m wondering if there’s an easier way to export my histograms produced by my cpp macro over to python for conversion to np arrays.

Thanks,
James
