Patch Release: Fix community vs. hub pipelines revision

• [Custom Pipelines] Make sure that community pipelines can use repo revision by @​patrickvonplaten

v0.22.0: LCM, PixArt-Alpha, AnimateDiff, PEFT integration for LoRA, and more

Latent Consistency Models (LCM)

LCMs enable a significantly fast inference process for diffusion models. They require far fewer inference steps to produce high-resolution images without compromising the image quality too much. Below is a usage example:

import torch
from diffusers import DiffusionPipeline
pipe = DiffusionPipeline.from_pretrained("SimianLuo/LCM_Dreamshaper_v7", torch_dtype=torch.float32)
To save GPU memory, torch.float16 can be used, but it may compromise image quality.
pipe.to(torch_device="cuda", torch_dtype=torch.float32)
prompt = "Self-portrait oil painting, a beautiful cyborg with golden hair, 8k"
Can be set to 150 steps. LCM support fast inference even <= 4 steps. Recommend: 18 steps.
num_inference_steps = 4
images = pipe(prompt=prompt, num_inference_steps=num_inference_steps, guidance_scale=8.0).images

Refer to the documentation to learn more.

LCM comes with both text-to-image and image-to-image pipelines and they were contributed by @​luosiallen, @​nagolinc, and @​dg845.

PixArt-Alpha

PixArt-Alpha is a Transformer-based text-to-image diffusion model that rivals the quality of the existing state-of-the-art ones, such as Stable Diffusion XL, Imagen, and DALL-E 2, while being more efficient.

It was trained T5 text embeddings and has a maximum sequence length of 120. Thus, it allows for more detailed prompt inputs, unlocking better quality generations.

Despite the large text encoder, with model offloading, it takes a little under 11GBs of VRAM to run the PixArtAlphaPipeline:

from diffusers import PixArtAlphaPipeline
import torch 
pipeline_id = "PixArt-alpha/PixArt-XL-2-1024-MS"
pipeline = PixArtAlphaPipeline.from_pretrained(pipeline_id, torch_dtype=torch.float16)
pipeline.enable_model_cpu_offload()
prompt = "A small cactus with a happy face in the Sahara desert."
