Error when trying to run stable diffusion for Intel arc using Jupyter notebooks. Kubuntu 22.04

[nom0to]

Hello everyone, could really use some help here. I've been trying to run the jupyter notebooks in order to use stable diffusion on my computer but the Jupyter notebooks is either very broken or I'm missing something. I'm currently receiving this error on the Configure Inference Pipeline step: `---------------------------------------------------------------------------

I'd really appreciate any help anyone can provide, I'm stumped but would still like to take advantage my Intel arc GPU.

Do you see any other Jupyter notebook from the collection working - for a consistency-check if your installation is complete?
Do you see notebooks working with the CPU?

From your "About your system" screenshot you have a SoC "intel-core-i5 12600k".
This has an integrated GPU.
From your description you mentioned an "Intel arc GPU".

Assuming your installation is complete and correct - then you might simply need to select the proper GPU device.
As you have at least two Intel GPUs in your system (and maybe even more from other, non-Intel-vendors) - your GPUs can be referenced via different device names, see:
"https://docs.openvino.ai/2023.0/openvino_docs_OV_UG_supported_plugins_GPU.html#device-naming-convention"

The code in your screenshot assumes a single GPU in your system:

4 options=core.available_devices + ["AUTO"],
5 value='GPU',
6 description='Device:',
7 disabled=False,

Can you check the value of the variable manually core.available_devices - and maybe just change the line value=GPU to e.g. `value=`GPU.0 or value=GPU.1``? (you would need to check if GPU.0 or GPU.1 is either the integrated or the discrete GPU).
