 2. As a rule, the notebooks do not require installation of additional software that is not installable by
    `pip`. We do not assume that users have installed XCode Developer Tools, Visual C++ redistributable,
    `cmake`, etc. Please discuss if your notebook does need C++ - there are exceptions to this rule.

     "Stable Diffusion is a powerful, open-source text-to-image generation model. There are multiple implementations of this pipeline in different frameworks. Previously, we already considered how to convert and optimize [PyTorch Stable Diffusion using HuggingFace Diffusers library](https://github.com/openvinotoolkit/openvino_notebooks/blob/latest/notebooks/stable-diffusion-text-to-image/stable-diffusion-text-to-image.ipynb). In this tutorial, we consider how to convert and run [Stable Diffusion from KerasCV](https://www.tensorflow.org/tutorials/generative/generate_images_with_stable_diffusion) that employs graph mode execution, which enhances performance by leveraging graph optimization and enabling parallelism and in the same time maintains a user-friendly interface for image generation. An additional part demonstrates how to run optimization with [NNCF](https://github.com/openvinotoolkit/nncf/) to speed up pipeline.\n",
