Same problem. As Augmented said, one has to enable --no-half-vae, which doubles the processing time of generating images in order to not have this error. As a result, it now takes >4 minutes for a single image to gen with a 2x upscale on my 3080.
I've already waited four months to try and use this extension with SDXL. I guess I may never be able to.
I'm having the same problem
When using Tiled VAE together with HiRes Fix, the image generation process will stop before completion if you select an Upscaler model (like
Ultrasharp
,foolhardy_Remacri
orESRGAN
) to drive the HiRes Fix.The same image generation process will work properly if you are select the
Latent
option (or any of its variants likeLatent_bicubic
) instead of a proper upscaler.A similar issue has been flagged in august over here: https://github.com/pkuliyi2015/multidiffusion-upscaler-for-automatic1111/issues/292#issue-1862078409
As suggested at the end of that discussion thread, using
--no-half-vae
can be used to bypass the problem, but this has a negative impact on the overall performance of the A1111-WebUI.In the log below, you can see the initial launch process followed by two image generation events. The first one uses Latent and was completed successfully. The second one used Ultrasharp as an upscaler and it fails at 50%, exactly when the HiRes Fix process should begin.
