This upgrader was not developed by us, all credit goes to Kim2091.
Installation method:
1. Rename the file to 4x-Ultrasharp .pth.
2. Copy the 4x-Ultrasharp .pth file to the "YOURSTABLEDIFFUSION_FOLDERmodelsESRGAN" folder.
3. Restart Stable Diffusion.
4. You can now find the new upgrader in the Extras tab.
Check whether the network connection is stable, try using a proxy or mirror source; confirm whether you need to log in to your account or provide an API key. If the path or version is wrong, the download will fail.
Make sure you have installed the correct version of the framework, check the version of the dependent libraries required by the model, and update the relevant libraries or switch the supported framework version if necessary.
Use a local cache model to avoid repeated downloads; or switch to a lighter model and optimize the storage path and reading method.
Enable GPU or TPU acceleration, use batch data processing methods, or choose a lightweight model such as MobileNet to increase speed.
Try quantizing the model or using gradient checkpointing to reduce the memory requirements. You can also use distributed computing to spread the task across multiple devices.
Check whether the input data format is correct, whether the preprocessing method matching the model is in place, and if necessary, fine-tune the model to adapt to specific tasks.
