LLM inference on Lunar Lake (LNL) iGPU is not working

[azhuvath]

Tried the sample openvino-genai code for iGPU and it not working. It is not working for NPU also. The below code exits without any exception. It works fine with CPU.

I was following the blog https://medium.com/openvino-toolkit/how-to-run-llama-3-2-locally-with-openvino-60a0f3674549 . It uses a dGPU and not iGPU. Not sure if it is not supported for iGPU.

device = 'GPU'
pipe = openvino_genai.LLMPipeline(args.model_dir, device)

I tried the INT4 model on iGPU. It was not working and hence created the INT8 model using the below command.

optimum-cli export openvino --model meta-llama/Llama-3.2-3B-Instruct --task text-generation-with-past --weight-format int8 --group-size 64 --ratio 1.0 --sym --all-layers llama-3.2-3b-instruct-INT8

Could you please share the error messages that you encountered when using GPU plugin?

On another note, could you please run the following command as share the output with us?
python3 -c "from openvino import Core; print(Core().available_devices)"

[azhuvath]

python3 -c "from openvino import Core; print(Core().available_devices)"

I do not get any error or exception. The code exits at the line
pipe = openvino_genai.LLMPipeline(args.model_dir, device)

The output requested for device supported is
(ov_env) PS C:\Users\devcloud\llama3.2> python -c "from openvino import Core; print(Core().available_devices)"
