ok looking at the most up-to-date version of this script, I don't see an
(obvious) issue on line 21. Do you know which version of YODA is installed
in your particular CMSSW release? Is the latest file different from what
you have?

Can you tell me if the entries in the histogram you're trying to convert
have been divided by the bin widths? I suspect the YODA converter expects
the entries to have been normalized this way.
