Chex

Chex is a library of utilities for helping to write reliable JAX code. It provides tools for instrumenting code (e.g., assertions, warnings), debugging (e.g., transforming `pmap`s to `vmap`s for single-device debugging), and testing JAX code across various execution contexts (e.g., JIT-compiled vs. non-JIT-compiled). The current version is 0.1.91, and it is actively maintained by Google DeepMind with frequent updates.
