Sep 30, 2018 · Hi - I’m contributing to a library for bayesian analysis and visualization (arviz), and we are trying to add a function to convert Pyro objects into data that can be used there. As part of that, I am …

Oct 15, 2023 · I am running NUTS/MCMC (on multiple CPU cores) for a quite large dataset (400k samples) for 4 chains x 2000 steps. mcmc.run actually ran until the end, but then died with an out-of …

Jan 31, 2018 · Hi there! This is my first time using Pyro so I am very excited to see what I can built with it.🙂 Specifically, I am trying to do finite Dirichlet Process clustering with Variational Inference. I want to …

Aug 31, 2020 · To plot a trace obtained via MCMC sampling we do: import arviz as az data = az.from_pyro(mcmc) az.plot_trace(data, compact=True); where mcmc is the fitted MCMC object from …
