There was a problem hiding this comment.
Nit: this JaxConfig has a few redundant params with the ScalingConfig, and both of these are passed through from scaling config.
Plus, this is a public API that users can modify, so you could end up with ScalingConfig != JaxConfig which is a bit confusing.
Let's discuss and address this in a followup PR. Ok to merge for now

1. Jax dependency is introduced in #58322 2. The current test environment is for CUDA 12.1, which limit jax version below 0.4.14. 3. jax <= 0.4.14 does not support py 3.12. 4. skip jax test if it runs against py3.12+. Signed-off-by: Lehui Liu <lehui@anyscale.com>

1. this PR added multihost GPU support for Ray Train JaxTrainer 2. Following Jax [GPU distributed doc](https://docs.jax.dev/en/latest/multi_process.html#gpu-example): if `ScalingConfig.use_gpu == True`, we add "cuda" as JAX_PLATFORMS. 3. if cuda is the jax platform, add CUDA_VISIBLE_DEVICES and initialize jax distributed with https://docs.jax.dev/en/latest/_autosummary/jax.distributed.initialize.html#jax.distributed.initialize --------- Signed-off-by: Lehui Liu <lehui@anyscale.com> Signed-off-by: YK <1811651+ykdojo@users.noreply.github.com>
