            Vectorise nested vmap

            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:

            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:

            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?.
