distreqx (pronounced "dist-rex") is a JAX-based library providing implementations of distributions, bijectors, and tools for statistical and probabilistic machine learning with all benefits of jax (native GPU/TPU acceleration, differentiability, vectorization, distributing workloads, XLA compilation, etc.).
The origin of this repo is a reimplementation of distrax, (which is asubset of TensorFlow Probability (TFP), with some new features and emphasis on jax compatibility) using equinox. As a result, much of the original code/comments/documentation/tests are directly taken or adapted from distrax (original distrax copyright available at end of README.)
Current features include:
- Probability distributions
- Bijectors
git clone https://github.com/lockwo/distreqx.git
cd distreqx
pip install -e .
Requires Python 3.9+, JAX 0.4.11+, and Equinox 0.11.0+.
Available at https://lockwo.github.io/distreqx/.
from distreqx import
- No official support/interoperability with TFP
- The concept of a batch dimension is dropped. If you want to operate on a batch, use
vmap
(note, this can be used in construction as well, e.g. vmaping the construction of aScalarAffine
) - Broader pytree enablement
