New PyTorch Interface in TMVA! (25 Mar 2021)

What if we combine PyTorch and TMVA? Ever wondered how ROOT utilizes powerful external MVA libraries making them easily accessible with a direct integration into the TMVA workflow? These interfaces between TMVA and Python frameworks are powered by the PyMVA backbone. All PyMVA methods provide the same plug-and-play mechanisms as TMVA.

View ROOT Files directly in VS Code! (11 Mar 2021)

As a heavy user of ROOT, many of the results of my data analysis are saved in ROOT Files and, honestly, I always found it a bit annoying to glance over them. The good news is that that isn’t the case any longer! Let me present ROOT File Viewer, an extension for Visual Studio Code that makes use of the wonderful JavaScript ROOT to display ROOT Files directly within VS Code, with just a click!
