Yep, changes LGTM!

[Rocketknight1]

Very confused about why the tests are failing - it seems to consistently be the convert_slow_tokenizer test. @ydshieh is that test failing on main?

[ydshieh]

@Rocketknight1 The job (of scheduled daily CI) running tests/utils errors out at the beginning of pytest launching. We don't see the report as no test being run there.

But other CircleCI runs also failing this test?

OK, it does fail when I run it, even with several previous commits.

Can ignore it in this PR as unrelated. I will check

[ydshieh]

actually, it starts to show up on circleci since

https://app.circleci.com/pipelines/github/huggingface/transformers/142539/workflows/dfa78853-c05b-4d18-a2d4-a4ff7a937514/jobs/1885341/tests

(@Rocketknight1 ) but there is no 3rd party lib changes compared to the run just before it ...

[ydshieh]

ok, unrelated warning maybe

{message : DeprecationWarning('builtin type SwigPyPacked has no module attribute'), category : 'DeprecationWarning', filename : '', lineno : 241, line : None}

i'm not sure why this tests continues to fail on this PR but not on all PRs .

[wirthual]

Also not sure. I opened a new one as a test here: #40319

If that does not work I can also start the process from the start to make sure it works.

Closing since we've merged #40319, and thank you for the PR!
