Is there an existing issue for this?

What happened?

Trying to generate a small bath at 768 x 768 with the new 768 Model.

When I pressed Generate I got the following error message:

Traceback (most recent call last):

AttributeError: module 'k_diffusion.external' has no attribute 'CompVisVDenoiser'

Steps to reproduce the problem

1. Try to Generate using the 768-V Model.

Command Line Arguments

--xformers

Not all samplers are yet supported with SD 2.0. When you switch to DDIM sampler it should work.
