Powerpax¶

A small collection of utility functions for JAX.

See the reference section for complete documentation. These utilities build on functionality in JAX and include:

chunked_vmap: Limit the number of vectorized steps evaluated in parallel which can reduce peak memory consumption with vmap.
sliced_scan: Keep a subset of iterations from a scan without first storing all intermediate steps.
checkpoint_chunked_scan: Perform a scan inserting checkpoints at regular intervals.
Static: Wrap a value to treat it as a static member of a pytree without defining a custom class.
