'OVStableDiffusionPipeline' object has no attribute 'image_processor'

[IlyasMoutawwakil]

Using main branches of optimum and optimum-intel.

A test started to fail in optimum-benchmark. I tested a minimal script and it also fails:

from optimum.intel.openvino import OVStableDiffusionPipeline
model = "hf-internal-testing/tiny-stable-diffusion-torch" # or a runway model

pipe = OVStableDiffusionPipeline.from_pretrained(model, device="CPU", export=True)
pipe(prompt="prompt", num_inference_steps=1)

The error is AttributeError: 'OVStableDiffusionPipeline' object has no attribute 'image_processor'

The problem comes from the new VaeImageProcessor which was added in optimum but only for ORTStableDiffusionPipelineBase
StableDiffusionPipelineMixin that's used by OVStableDiffusionPipeline supposes its existence without instantiating it.
Should it be added in each sub-package ?

I just noticed the PR #421, great work!

Yes we will merge #421 after the next optimum release !
