[feat] IP Adapters (author @okotaku )

[yiyixuxu]

the author of this PR is @okotaku
and the original PR: #4944

this is a demo of alternative design (alterative to #4944) that add the image_projection layer to Unet

works with SD, SDXL

it works with text-to-image, image-to-image, inpaint, see text-to-image example below, and you can find examples for img2img here and inpaint here

I think it is fine for now
we would very much like to support face models. It won't take much work and we will ask some help from the community soon :)

let me know if you're interested in working on this

[patrickvonplaten]

Great job! Let's merge 🚀

[alexblattner]

I've been working on this for 2 weeks and now it's built in.... Thanks haha

[sayakpaul]

Open a new issue for this. It's ideal for users to comment on PRs after they have been merged.

[TonyLianLong]

This PR seems to break the positional arguments for super calls as it adds a image_encoder before requires_safety_checker. An example of what breaks after the change can be shown here (with the commit fixing it): #5993

We might want to clarify this in the release note for the next release.

[yiyixuxu]

hi @TonyLianLong
I looked at #5993 I think it's because it used StableDiffusionPipeline as the base class, instead of DiffusionPipeline

[MackorLab]

Hello, I’m just starting to program in Python and I still don’t understand exactly how to do it correctly
Please tell me Can I save the finished file in mp4 format?

Hi, @yiyixuxu

Could you also provide an img2img IPAdaptor sample for SDXL? I always got below error when using SDXL. Thanks!

Never mind, I figured it out, I need to use the sd_models' image encode explicitly. like this:

image_encoder=CLIPVisionModelWithProjection.from_pretrained(
<IP-AdapterModelPath>subfolder="models/image_encoder",
torch_dtype=torch.float16,
).to("cuda")
pipeline=StableDiffusionXLImg2ImgPipeline.from_pretrained(
<pretrainmodelpath>
, torch_dtype=torch.float16
, image_encoder=image_encoder
)
pipeline.to("cuda")

[thibaudart]

is it possible to load multiple image as reference for IP adapter?

[patrickvonplaten]

Hey @thibaudart,

Hope you're doing well - we've just recently opened the Discussion tab on the Diffusers' repo: https://github.com/huggingface/diffusers/discussions
Would you mind posting your question there?

of course

[xingyouxin]

For controlnet and ip-Adapter, I have a question about the multi-computation by using a batch size, e.g., batch_size = 4. I try to put image, prompt, and generator lists, etc. into the pipeline. But the result failed with an error: ValueError: ip_adapter_image must have same length as the number of IP Adapters. Got 4 images and 1 IP Adapters.

Thus, maybe the multi-computation by using a batch size is not added in this project. I am not sure. Could anyone help me? Thanks.

[asomoza]

it would be better if you open a new issue with this, also you will need to provide us with a minimal reproducible code.

Without it, I can say that the error message says it all, you are passing 4 images to the ip adapters but you're only loading one ip adapter.

Probably the error lies in how are you passing the images for the batch.

Hello, Mr. asomoza. Thanks for your reply. With your help, I have taken some tests but still failed. So I open an issue about the details.

Dear asomoza, it seems that I have figured out my problem. Finally, I find that the ip-Adapter embedding is not supported to work with a batch of images separately. It deals with all the images in one batch uniformly. Thus, the better way is to embed the adapter images one by one and then cat (torch.cat) them up. Then we pass the catted embeddings into our pipeline to generate images in one batch separately. The details can be seen in this issue #7933. Thank you very much.
