[Tune][Doc] Restructure API reference #32311

justinvyu · 2023-02-08T09:13:41Z

Why are these changes needed?

This PR splits up long API refs into individual pages, one dedicated to each method/class. There are now 3 layers: an index page (ex: doc/tune/api/api.rst), a summary page for each group of APIs (ex: doc/tune/api/trainable.rst), and an individual page for each API (ex: doc/tune/api/docs/tune.Trainable.rst).

This PR is a followup to #31204, which made the same changes for Ray Data docs.

Can these be combined somehow? Special case for the newly added cluster autogenerated files.

@c21 should we conform to one structure? Though it does mess with backwards compatibility for this job submission page.

Yes I think we should conform to one structure (non-blocking for this PR). Let me take a look how easy the change is.

There was also a discussion about whether we should do reference/api or api/doc as the standard.

Also looks like I can use /doc/source/**/doc as wildcard for nested dirs.

Talked to @jjyao separately. We can use api/doc here. To rename to reference/api, we plan to have a separate discussion.

just keep in mind that api leads to shorter URLs, too. but consistency is more important

Overall looks great, most of my comments are about changes we can make in the future 😄

It's already mentioned at the top of this file, but most/all of this page should exist in a user guide instead. We don't have to make the change in this PR though!

Agreed, I am thinking:

Move high level trainable stuff to key concepts trainable section

Move checkpointing guides to a new "Tune Checkpointing" user guide (the old one didn't have much to do with checkpointing, and a new one needs to be made)

Move the advanced resource allocation section to the tune resources user guide

Reuse actors section can probably go to tune lifecycle user guide.

Same thing in master but we should fix this import.

I guess this is because doc requirements != Tune requirements? How should we go about fixing this?

nit: @c21 any suggested practice for separating out the constructor? I saw in Datasets APIs we explicitly do.

@matthewdeng - I think it's fine to keep it as it is here. I was following other system, such as Pandas - https://pandas.pydata.org/docs/reference/series.html .

Can we explicitly set this include _call_ as was done previously?

Currently this shows __init__ instead and feels a bit mismatched.

I don't think it's actually possible to include specific members with the autosummary. Best thing I could do was have it right below.

Just checking, are you keeping Tune Internals and Tune Client API unchanged intentionally?

Yep, for Tune Internals, I wasn't sure how to list out all members/methods with their docstrings if I used autosummary. And since that section is not really meant for external users to search for and use as API calls, I decided to leave it fully expanded.

For Tune Client, there was only 1 class, and I think it is fine as is.

Ack, though we should probably move Callback and PlacementGroupFactory out of Tune Internals.

I think it would make sense to move PlacementGroupFactory directly into the Trainable Utilities section, next to with_resources.

Callback is a bit strange... it's a public tune API, which exposes internals about the trials, and is used by air.RunConfig... we should probably revisit this down the line.

Thoughts?

Moved Callback + PGF to better places.

Clicked through several docs, and looks great to me, thanks @justinvyu!

Just FYI #32307 for Serve API is just merged, so rebasing to master should resvole the conflict here.

@maxpumperla Do you know why these errors are showing up?

/ray/doc/source/tune/api/doc/ray.tune.sklearn.TuneSearchCV.rst:48:<autosummary>:1: WARNING: term not in glossary: fit

The links all work fine, and fit is not missing in either of the generated autosummary/autofunctions.

See here and here.

Update: For now, I have changed this section back to what it was before (not showing any inherited members).
