超簡單AI繪圖工具Stable Diffusion安裝篇2024最新版

Jack and Ellie introduce themselves and the purpose of the video, which is to help users reinstall Stable Diffusion (SD) and understand recent changes in the installation process due to evolving community methods. They address new users or those returning to SD after a break, offering guidance on reinstalling and recommending essential extensions. The video covers both 'lazy' and 'standard' installation methods, catering to users with different needs, especially based on whether they intend to train models. It also discusses hardware requirements such as the need for an Nvidia GPU with over 6GB of memory. The goal is to provide a comprehensive and updated installation guide.

This paragraph explains the 'lazy installation' method for users who do not plan on training models. The process involves downloading the webui from the official source, extracting the files, updating the program via 'update.bat,' and optimizing it with commands like '--xformers' for better performance. For users with limited VRAM, it suggests using '--medvram.' The system will automatically download the required packages and launch the webui, with the installation duration varying based on internet speed. Once installed, users can access the webui by running 'run.bat.'

For users planning to train models, the standard installation method is recommended. It involves three steps: installing Python (version 3.10.6), Git, and disabling PowerShell's security lock. The video highlights the importance of removing older Python versions and ensuring 'add to PATH' is checked during installation. After installing Git, users will need to use PowerShell to run specific commands to enable Git operations. The webui is then installed by cloning the repository using Git and running it with 'webui-user.bat.' This method is crucial for users who intend to train models.

Once the webui is installed, this section covers the installation of various essential extensions. It outlines how to install extensions via the Extensions tab by pasting the URL and waiting for a success message. Extensions covered include: Chinese language localization, prompt assistance tools, face and hand detail fixes (Adetailer), image quality enhancement tools, high-resolution upgrades, and advanced prompt tools. The ControlNet extension is highlighted for its role in controlling AI-generated images, especially for character poses. The process concludes by advising users to restart the webui to apply the changes.

This section explains the final configuration steps for the webui, including language localization settings, VAE options for improved image generation, and setting up the CLIP model for better prompt handling. The prompt tool can be configured to automatically translate Chinese inputs, with Google translation being the default option. The paragraph emphasizes the importance of restarting the webui after these changes to apply the settings.

Jack and Ellie wrap up the video by encouraging viewers to explore additional resources provided in the description, including tutorials on model recognition and prompt syntax. They also invite users to join the community on Discord for further discussions and support. They close by thanking viewers and suggesting they consider subscribing to their channel or joining as members.
