the quality of generated image is low by benchmark on stable diffusion v1.5

[aoke79]

I've run the benchmark to test stable diffusion v1.5, but the quality of generated image is low. I doubted there are something computing wrong in the process.
I compared it with optimum-intel. and set the same prompt, steps (20), resolution (512x512), and got very different quality image. please have a look at.

@aoke79 please share the command you've run to get those images in optimum and in the benchmark?

Thank you!

[aoke79]

python benchmark.py -d GPU --model "C:\AIGC\openvino\models\stable-diffusion-sdv1_5" --prompt_file "prompts/stable-diffusion.jsonl" -n 3
the model was converted from hugging-face runway stable diffusion.

@aoke79 Please check guidance_scale in https://github.com/openvinotoolkit/openvino.genai/blob/master/llm_bench/python/prompts/stable-diffusion.jsonl. Could you try it with the value of 7.5?

[Edward-Lin]

I have set up the same parameters for both cases. it should not be the root cause.

I've udpated the environments, like below, but the generated image is still wrong, nothing better.
python -m pip install --upgrade pip
pip install --pre -U openvino --extra-index-url https://storage.openvinotoolkit.org/simple/wheels/nightly

please refer what I've attached for the details.

@Edward-Lin Please check above comment. guidance_scale 7.5

Have you ever tried? it did not work for me.
