v0.19.2

We still had some bugs 🐛 in 0.19.1 some bugs, notably:

SDXL (Kohya-style) LoRA

The official SD-XL 1.0 LoRA (Kohya-styled) is now supported thanks to https://github.com/huggingface/diffusers/pull/4287. You can try it as follows:

from diffusers import DiffusionPipeline
import torch

pipe = DiffusionPipeline.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0", torch_dtype=torch.float16)
pipe.load_lora_weights("stabilityai/stable-diffusion-xl-base-1.0", weight_name="sd_xl_offset_example-lora_1.0.safetensors")
pipe.to("cuda")

prompt = "beautiful scenery nature glass bottle landscape, purple galaxy bottle"
negative_prompt = "text, watermark"

image = pipe(prompt, negative_prompt=negative_prompt, num_inference_steps=25).images[0]

In addition, a couple more SDXL LoRAs are now supported:

(SDXL 0.9:)

Thanks to @isidentical for their sincere help in the PR.

Batched inference

@bghira found that for SDXL Img2Img batched inference led to weird artifacts. That is fixed in: https://github.com/huggingface/diffusers/pull/4327.

Downloads

Under some circumstances SD-XL 1.0 can download ONNX weights which is corrected in https://github.com/huggingface/diffusers/pull/4338.

Improved SDXL behavior

https://github.com/huggingface/diffusers/pull/4346 allows the user to disable the watermarker under certain circumstances to improve the usability of SDXL.
