cc @ydshieh anything I should do differently?

[ydshieh]

@vasqu It's triggered, but failed at a step (reply to comment) and the tests are not run.

https://github.com/huggingface/transformers/actions/runs/15250152202/job/42884998108

I'm not sure why, but I will re-run it and see how it goes.

Slow tests failed, but not sure if this PR caused the failure since we only changed the slow path which is not executed on GPUs, perhaps they failed since the beginning?

[younesbelkada]

We're not able to extract the expected text from the logs and we don't have access to T4 GPUs.. is there a way to extract the output from the logs?

[ydshieh]

I can update the expected value this afternoon

[dhiaEddineRhaiem]

i pushed a fix in the Integration test EXPECTED_TEXT
could you please rerun the slow-path test?
