Python 3.12 alpha support #45904

Open can-anyscale opened 2 weeks ago

can-anyscale commented 2 weeks ago

Python 3.12 for Ray is now available under alpha support, starting from 2.31.0 version. You can either:

Install it via pypi, as your usual workflow, starting from 2.31.0 version going forward
Find the download link as a nightly wheel in this documentation: https://docs.ray.io/en/master/ray-overview/installation.html.

During the alpha and experimental phase, the wheel has been passing our smoke and critical tests, and we are looking forward to the community using it and giving us feedback as we continue to stabilize all use cases.

Following the alpha phase, we are now working on publishing the Ray Docker images. Thank you for your continuous feedback and patience.

June 21st updates:

https://github.com/ray-project/ray/pull/45726/files is the current work to update python 3.12 across ray core, serve, data, ml and rllib
This task is highly complex since Ray supports numerous ecosystems and dependencies, many of which do not yet support Python 3.12 (e.g., Horovod, Gymnasium, Sklearn, MosaicML, among others).
We are making strategic decisions to allow the community to benefit from parts of Ray, rather than delaying an entire Ray release. Stay tuned for updates.

Thanks for the update. I appreciate the focus on stability. The last thing I want is to upgrade to 3.12 and then have to roll back to 3.11.

@can-anyscale will docker images be pushed at this alpha stage. Is this all thats needed to make that happen https://github.com/ray-project/ray/pull/46285?

can-anyscale commented 3 days ago

@wallies the docker images do not come with alpha stage yet, it will be the next and the last GA stage of the release

the docker image, in addition to just the ray wheel, comes with a set of dependencies pre-installed, so the most time-consuming part is to upgrade this list https://github.com/ray-project/ray/blob/master/python/requirements_compiled.txt to python 3.12; we are actively working on this
