Orbax is a namespace providing common utility libraries for JAX users.
pip install orbax-checkpoint (latest PyPi release) OR
pip install 'git+https://github.com/google/orbax/#subdirectory=checkpoint' (from this repository, at HEAD)
import orbax.checkpoint
Orbax includes a checkpointing library oriented towards JAX users, supporting a variety of different features required by different frameworks, including asynchronous checkpointing, various types, and various storage formats. We aim to provide a highly customizable and composable API which maximizes flexibility for diverse use cases.

Check out our colab for a hands-on introduction.
pip install orbax-export (latest PyPi release) OR
pip install 'git+https://github.com/google/orbax/#subdirectory=export' (from this repository, at HEAD)
import orbax.export
Orbax also includes a serialization library for JAX users, enabling the exporting of JAX models to the TensorFlow SavedModel format.
Note that orbax-export requires TensorFlow, but does not include it by default to allow for flexibility in version choice. If you wish to install with standard TensorFlow, please use pip install orbax-export[all].

Orbax was initially published as a catch-all package itself. In order to minimize dependency bloat for users, we have frozen that package at orbax-0.1.6, and will continue to release future changes under the domain-specific utilities detailed above (e.g. orbax-checkpoint).
As we have preserved the orbax namespace, existing import statements can remain unchanged (e.g. from orbax import checkpoint).
