Fix #3661
This is because
from_ckpt
usesFrozenCLIPEmbedder
forStableDiffusionPipeline
but it should beFrozenOpenCLIPEmbedder
in Stable Diffusion 2.x.The original
download_from_original_stable_diffusion_ckpt
uses a layer that only presents in Stable Diffusion 2.x checkpoint to infer themodel_type
, which is not work withfrom_ckpt
because it overrides the param. I think we can just leave themodel_type
empty for Stable Diffusion pipelines and then it will be inferred correctly.By the way, this PR also fixes some invalid assignments for
model_type
.
