The purpose
Stable Diffusion Forge typically requires an NVIDIA GPU (like a GeForce card) to run. Here, we’ll explain how to get Stable Diffusion Forge working on a PC that doesn’t have an NVIDIA GPU, using only the CPU.
Environment Setup
Download
Open following page
Scroll down the page to find the “Installing Forge” section, then click on the recommended binary to download it.

Extract
Extract the downloaded ZIP file to your desired folder.
Modify bat
Open the following file with an editor like Notepad.
webui¥webui-user.bat
You will modify the following line:
set COMMANDLINE_ARGS=
After
set COMMANDLINE_ARGS=--always-cpu --skip-torch-cuda-test --no-half --opt-sub-quad-attention --upcast-sampling --opt-sdp-attention
That completes the environment setup.
--always-cpu
and --skip-torch-cuda-test
are essential, but feel free to adjust the other arguments as needed.
Install model
It appears that stable-diffusion-webui-forge doesn’t come with models installed by default. Please refer to the following guide to install the models.
Execute
Run run.bat
located inside the extracted folder.
If you see the following error during execution (the process will continue), run the displayed git config~
command. This error might appear repeatedly; if it does, run the command again (the folder path in the arguments should have changed).

If your browser launches and displays the GUI as shown below, the setup is successful!

Result
You successfully created an image by entering a prompt into the displayed GUI and clicking Generate.
