CPU only?

[seghier]

Hello
Can SUPIR work with cpu only?
I got this error

[Tiled VAE]: the input size is tiny and unnecessary to tile.
!!! Exception during processing !!!

I have no idea, to get past that error you'd have to uninstall xformers first.

[seghier]

Thanks but xformers is necessary for some other custom nodes

I was under the impression xformers is only for Nvidia GPUs?

[seghier]

I don't know but some custom nodes don't works and always ask for installing xformers

[Amit30swgoh]

what to do then? xformers

[softyoda]

Does anyone know if SUPIR work with cpu only?
