  • The value argument must be within the support . . . - Pyro Discussion Forum
    Finally solved this! TL;DR: using float64 instead of float32 solved the issue Users probably should prefer this practice when auto guides and models containing latent variables sampled from distributions with simplex support are combined for SVI Background I checked where the problem arises in AutoNormal As assignment is a latent variable sampled from RelaxedOneHotCategorical, the value in
  • Variational Inference for Dirichlet process clustering - Pyro . . .
    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 generalize this into a Chinese Restaurant Process involving an “infinite” number of states But for now, I am just generating 1-D data from 3 Gaussians with proportions given by a
  • Mini batching with Bayesian GPLVM - Pyro Discussion Forum
    Trying to define mini-batch logic for Bayesian GPLVM training but unsuccessful so far following the suggestions in this older thread: Pyro Bayesian GPLVM SVI with minibatching So the suggestion in this thread is to use: X_minibatch = pyro sample(…, dist Normal(x_loc[minibatch_indices], x_scale[minibatch_indices])) y_minibatch = y[minibatch_indices] self base_model set_data(X_minibatch, y
  • How to get prediction scores with Pyro models?
    pyro sample("y", y_dist, obs=y) # or pyro factor("y_loss", y_loss_tensor) return I am not familiar enough with the details of your model to fix the code for you, but this is covered in detail in the tutorials I linked to, especially the Bayesian regression with SVI section of the Bayesian regression tutorial
  • How to begin learning probabilistic programming? - Pyro Discussion Forum
    Can anyone help me with some resources to learn probabilistic programming with pyro? I do not have any background on probabilistic programming I skimmed through the tutorials and examples in pyro ai but it seems they assume a background in probabilistic programming concepts
  • Batch processing numpyro models using Ray - forum. pyro. ai
    Hello again, Related post: Batch processing Pyro models so cc: @fonnesbeck as I think he’ll be interested in batch processing Bayesian models anyway I want to run lots of numpyro models in parallel I created a new post because: this post uses numpyro instead of pyro I’m doing sampling instead of SVI I’m using Ray instead of Dask that post was 2021 I’m running a simple Neal’s funnel
  • Truncated Log normal distribution - Pyro Discussion Forum
    I saw that pyro is planning to add at least a truncated normal distribution soon However I want to implement a truncated normal distribution as prior for a sample param I came accross the rejector distribution and thought this could maybe provide a solution I tried the following: class TruncatedLogNormal(dist Rejector): def __init__(self, loc, scale_0, max_x0): propose = dist LogNormal(loc
  • Initialize each chain of MCMC separately - forum. pyro. ai
    Hi! I am running NUTS in a setting where data increases over time What I would like to do is to is to initialize the new chains with the last sample from each of the previous chains This works fine when I only have one chain as I can extract the last sample and use init_strategy = numpyro infer util init_to_value(values=lastsample) in my NUTS kernel This approach does not work for multiple
  • How to use to_event ()? - Pyro Discussion Forum
    How to know which 2 parameters are set to be dependent if I set to_event(2)?
