Thanks Anya!

I think if we follow the proposal here #36 to publish kubeflow-trainer-api, we won't have problems publishing kubeflow sdk to pypi.org as we can easily replace the git+https with a python wheel from pypi.org with master tag instead of specific version which will always give us the latest code.

We don't currently publish kubeflow-trainer-api with a master tag to PyPI. If we decide to do something like that, it would be part of kubeflow/trainer#2155. For now, we can move this to dependency-groups for dev deps

That said, have you seen other projects publishing packages with a master tag? I don't think PyPI supports mutable master or main tags.

Instead, what we could do for the Kubeflow SDK is publish a kubeflow-nightly version.
Any thoughts on that @szaher @andreyvelich?

[szaher]

you're right, pypi.org doesn't support mutable versions like main/master/stable.

so I think for now our best option is to use dependency-groups let uv install it by default.

We may have to adjust the approach when there'll be multiple release branches maintained but we are not there yet.
