The purpose
We will build a Stable Diffusion environment on a local Windows PC that supports CUDA.
Background
This blog has followed the difficult path of getting Stable Diffusion to run on an AMD GPU, but setting up the environment on a PC with CUDA is actually quite easy. Despite this, many other guides use a more complicated approach (involving installing Git and Python)
An article for non-CUDA environments.
AMD GPU(DirectML)
CPU
Environment setup
Download
Open the page below.
Scroll down the page, find the ‘Installing Forge’ section, and click the recommended binary file to download it.
Extract
Unzip the downloaded file into any folder of your choice.
Install model
It seems that stable-diffusion-webui-forge doesn’t come with any models pre-installed.
We will install them by following the guide in the article below.
Start
Run the run.bat file inside the extracted folder.
If you see the following error during the process (it will continue to run), just run the git config~ command that is displayed. This error might pop up multiple times. If it does, just re-run the command, as the folder path in the argument should have updated.
If a browser launches and the GUI appears as shown below, it means you have succeeded.
Result
I was able to create an image by entering a prompt into the GUI that appeared and clicking ‘Generate’.
Trouble Shooting
The driver versions are mismatched.
If you get a driver version mismatch error (or if the driver isn’t installed), please install the correct driver from the link below.
Runtime error （Input type (float) and bias type (struct c10::Half) should be the same）
If you get the Input type (float) and bias type (struct c10::Half) should be the same error during image generation, follow these steps.
Open the webui-user.bat file located in your installation_folder\webui directory.
Find the line below, make the correction, and restart Stable Diffusion.
Before:
set COMMANDLINE_ARGS=
After:
set COMMANDLINE_ARGS=--no-half
Runtime error （memory）
If image generation fails when using the GUI, the problem is most likely a lack of memory (VRAM). (Even if the error message doesn’t mention memory, that could still be the cause.)
Try the following improvements.
Make the generated images smaller
Could you please make the Width and Height of the generated images smaller?
Keep in mind that making them too small might result in poorly formed images. (It’s generally not recommended to go below 512×512.)
Modifying Startup Options
Open the webui-user.bat file located in the \webui folder inside your installation directory.
Look for the following line, modify it, and then restart Stable Diffusion.
Before:
set COMMANDLINE_ARGS=
After:
set COMMANDLINE_ARGS=--lowvram
