kandi X-RAY | numpyro Summary
NumPyro is a lightweight probabilistic programming library that provides a NumPy backend for Pyro. We rely on JAX for automatic differentiation and JIT compilation to GPU / CPU. NumPyro is under active development, so beware of brittleness, bugs, and changes to the API as the design evolves.

...ANSWER
Answered 2021-Nov-05 at 01:37I believe Vectorization guidelnes for jax is quite similar to your question; to replicate the logic of nested for-loops with vmap requires nested vmaps.
The cleanest approach using jax.vmap
is probably something like this:
QUESTION
I am trying to use a custom VJP (vector-Jacobian product) function as a model for a HMC-NUTS in numpyro. I was able to make a single variable function that works for HMC-NUTS as follows:
...ANSWER
Answered 2021-Feb-11 at 03:08def model(x,y):
sigma = numpyro.sample('sigma', dist.Exponential(1.))
x0 = numpyro.sample('x0', dist.Uniform(-1.,1.))
A = numpyro.sample('A', dist.Exponential(1.))
hv=vmap(h,(0,None),0)
mu=hv(x-x0,A)
numpyro.sample('y', dist.Normal(mu, sigma), obs=y)
