Stable Diffusion webui CPU only on ARM64 Platform
Stable Diffusion webui is a web service based on Gradio library for Stable Diffusion. The installation process can automatically set up the environment and install Stable Diffusion, which can save a lot of time. However, it requires an NVIDIA or AMD GPU to install it. If you want to install Stable Diffusion WebUI without a GPU, some modifications are necessary.
Using a CPU to run Stable Diffusion can be painful, so this article is just for fun.
Platform is Ampere Altra Mt. Collins system with 2 Ampere Altra CPU, total 160 cores.
OS: ubuntu 22.04.02 LTS
Seems Stable Diffustion webui needs python 3.10, so, ubuntu 22.04 is good choice.

If CPU number is too much, compile qtwebengine will fail, seems ninja compile issues.
it better to reduce CPU number under 8, batter number is 4 or 6.
just put MAKEOPTS=”-j 4″ on your /etc/portage/make.conf
It can be roll back after compile qtwebengine.
modify package.env can support special MAKEOPTS command on some packages.
ex:
echo "dev-qt/qtwebengine lowcpu.conf" | sudo tee -a /etc/portage/package.env
mkdir -p /etc/portage/env
echo "MAKEOPTS=\"-j4\"" | sudo tee /etc/portage/env/lowcpu.conf
