Thank you for tracking down all the issues @pcuenca, looks great!

Cool good job!

(Question) would it already make sense to add some tests for MPS?

Yes, we already have some, maybe we can add a few more :)

@anton-l tests pass locally in my computer, any idea why that test might be failing?

[anton-l]

@pcuenca looks like first time they've failed was on the pipeline tests PR: https://github.com/huggingface/diffusers/actions/runs/3312968864

But the test code is identical:

• before:

  diffusers/tests/test_pipelines.py

  Line 264 in 9bca402

  def test_ddim(self):

• after:

  diffusers/tests/pipelines/ddim/test_ddim.py

  Line 45 in 2fb8faf

  def test_inference(self):

So I'm very puzzled... Unless the test order mattered and we've had mps warmup steps from other tests affecting this one?

Looks good, thanks a lot!

[anton-l]

An identical test_inference_2 passes after test_inference fails, looks like we need even more warmup for DDIM?
