Help with RDataframe tutorial

ROOT
1

I am currently learning how to use RDataframe as prep for a research project. I’ve had trouble getting the dataModel.py program in the RDataframe tutorial to work on lxplus. My ROOT version is 6.24/06 and my python version is 3.9.6. It works on SWAN (which uses an earlier ROOT version) but not lxplus. I get the following error message:

I’m guessing that some variable name has been changed between ROOT versions, and that is what is causing the error, but I’m unsure of how to fix it.

You are trying to use a new tutorial version with an old ROOT version (e.g., for “RVecD” you need ROOT 6.26).
