I’ve contributed to pymc actually (https://docs.pymc.io/api/distributions/timeseries.html#pymc3...) and used it in research projects. So when I say I find Pyro/PyTorch easier to use, it’s not wishful thinking.

I don’t have pymc code anymore since we have moved to Stan, and now starting porting code to Pyro.

Why do that when AD does it for you?
