[Bug]: unable to save checkpoint preview pictures when model is in symlink folder

[halr9000]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What happened?

See #7266. Same symptom, but on the Checkpoints tab

Steps to reproduce the problem

1. create folder for models as in example below
2. generate any image
3. open checkpoints tab
4. hover over one of them and click replace preview
5. image is not replaced and error appears in console

My example folder layout

d:
  /stable-diffusion
    /models
      /stable-diffusion<- symlink source
   /auto <- sd-ui main folder
    /models
      /stable-diffusion<- symlink destination

What should have happened?

pic should be replaced

I don't have the same issue myself.

~~I think you're probably using --ckpt-dir or --data-dir or one of those? And you have the same issue as https://github.com/AUTOMATIC1111/stable-diffusion-webui/issues/7041 It appears that the alternate root directory command line args probably break previews, for a similar (but separate) reason as to why symlinks were broken.~~ EDIT: no, you're not, you posted your command line args. Huh. That's got me confused then.

On an updated copy of the WebUI, I can both update and view previews on all tabs within extra networks, on both Windows and Linux.

It might be related to the type of symlink you made? (Symlink vs Hardlink vs Junction).

Just plain ole symlinks. Haven't tried in linux or wsl2, that's too much work for me at the moment. The other tabs work fine, it is indeed bizarre.

I had the problem of the images the additional networks tab not working on any of its subtabs (embeddings, hypernets and Loras), does anyone know what might be causing it?

[CErratum]

An oddity: images worked for me when I had the entire models folder symlinked; however, it seems anything below that causes issues with previews - i.e., if you have the stable-diffusion models folder symlinked, or a subfolder created for sorting.

Since ~1.5 update. And it doesn't update the Extra Networks list right away, nor the new "Settings" window. You must do a REFRESH-button press to get the new preview image.

The file is created as it should of course.
