I would like to reproduce the example, , fitting a target distribution using hmc I am using predictive to predict y for a given set of parameters Here is the code, import numpy as np import torch import torch.nn as nn import pyro import pyro.distributions as dist from pyro.infer i…

I created a deterministic convolutional neural network for classification, and then lifted it to a probabilistic network using pyro.random_module()
I further tuned the learning rate as a hyper parameter during svi optimization
While looping over svi, i sampled the random network many times, e.g., sampled_models = [guide(none, none) for _ in range(num_model_samples)], to get many instances. I’m seeking advice on improving runtime performance of the below numpyro model I have a dataset of l objects This function is fit to observed data points, one fit per object
Ugh, seems like i usually figure out the answer to my question right after caving and posting to a forum about it You have to provide an arg This optimizer needs to be a class of torch.optim.optimizer But it seems that providing a pyrooptim class isn’t allowed
This problem was fixed like so
Hi everyone, i am very new to numpyro and hierarchical modeling There is another prior (theta_part) which should be centered around theta_group I am trying to use lognormal as priors for both Hi there, i’m building a model which is related to the scanvi pyro example for modeling count data while learning discrete clusters for data, and i’m having an issue with the parameter fit where the model seems to have a vanishing gradient for fitting zeros
Hi all, i’ve read a few posts on the forum about how to use gpu for mcmc Transfer svi, nuts and mcmc to gpu (cuda), how to move mcmc run on gpu to cpu and training on single gpu, but there are a few questions i still have on how to get the most out of numpyro There is also this blog post comparing mcmc sampling methods on gpu, and although the model is built in pymc, it uses numpyro.
