kandi X-RAY | numpyro Summary

numpyro is a Python library typically used in Artificial Intelligence, Machine Learning, Deep Learning, Pytorch applications. numpyro has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has medium support. You can install using 'pip install numpyro' or download it from GitHub, PyPI.

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.

I 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:

A JAX custom VJP function for multiple input variable does not work for NumPyro/HMC-NUTS

Asked 2021-Apr-07 at 16:08

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:

def 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)

Vulnerabilities

No vulnerabilities reported

Install numpyro

Limited Windows Support: Note that NumPyro is untested on Windows, and might require building jaxlib from source. See this JAX issue for more details. Alternatively, you can install Windows Subsystem for Linux and use NumPyro on it as on a Linux system. See also CUDA on Windows Subsystem for Linux and this forum post if you want to use GPUs on Windows.

Support

Unlike in Pyro, numpyro.sample('x', dist.Normal(0, 1)) does not work. Why?. You are most likely using a numpyro.sample statement outside an inference context. JAX does not have a global random state, and as such, distribution samplers need an explicit random number generator key (PRNGKey) to generate samples from. NumPyro's inference algorithms use the seed handler to thread in a random number generator key, behind the scenes. Can I use the same Pyro model for doing inference in NumPyro?.
