So it seems that CMS has added some rather complete tutorials that describe the Combine model (HT @kpedro88): - [Combine Physics Models](https://cms-analysis.github.io/HiggsAnalysis-CombinedLimit/part2/physicsmodels/) - [Combine Tutorial Long exercise](https://cms-analysis.github.io/HiggsAnalysis-CombinedLimit/part5/longexercise/)

Just dumping here that @ajgilbert gave a [session on Combine](https://indico.cern.ch/event/1088121/contributions/4575745/) (:+1:) at the first hands-on [workshop on publication of statistical models](https://indico.cern.ch/event/1088121/overview) where the last 4 slides are relevant to pyhf...

@Ga0l thanks for the Issue and for reporting this. :+1: What version of `torch` do you have installed? Can you give us a `requirements.txt`?
