I updated my webui directory very often and run into a lot of problems every time I updated it. The most recent problem I had is this error.
When I googled the solution for this problem, I saw someone suggested reinstall webui. It took me a while to reinstall everything. However, it did not work after reinstallation of webui. I still got this upscaler named [] not found error. Then I checked the settings and found that the upscaler for img2img is not selected. I selected an upscaler and apply settings and I am back to business.
- Click on Settings on the top.
- Clcik on Upscaling on the left hand side.
- Select an upscaler from the Upscaler for img2img drop down.
- Click on Apply Settings.
If you want to add a new Upscaler,what should I do?
