Hi @zhaoyun0071, diffusers 0.25.0 does not support the two models you mentioned because they are experimental versions. PR #6276 is adding support for IPAdapter FaceID.

Hi @fabiorigano , does diffusers 0.25.0 and higher support it now? I still do have the same error when loading the models.

[fabiorigano]

hi @katarzynasornat, all Face ID models are supported with #7186, and thus starting with diffusers 0.28 (dev, the current version at the time of this writing)

EDIT: I think there is a typo in the example (red marked). It should be ip_adapter_image_embeds instead of ip_adapter_image :)

@fabiorigano thanks for your reply! I have tried to follow #7186 with the code provided, however I am getting an error:

AttributeError: 'NoneType' object has no attribute 'parameters'

Is that a normal behaviour? Did I miss something?

I attached my gist with execution below.

[fabiorigano]

@katarzynasornat when using FaceID, pass ip_adapter_image_embeds instead of ip_adapter_image. Follow the docs https://huggingface.co/docs/diffusers/main/en/using-diffusers/ip_adapter#face-model (snippet after Full Face example)

EDIT: I think there is a typo in the example (red marked). It should be ip_adapter_image_embeds instead of ip_adapter_image :)

yes, but don't follow PR's examples, as we changed few things during integration
docs are updated :)

only support sd1.5，sdxl not support

Hi @fabiorigano ,

Thanks for the great work! I was wondering if the docs are updated. I copied and pasted this (I am using the ip-adapter-faceid-plusv2_sd15.bin ckpt)

from insightface.utils import face_align

num_images = 1 # Not in the docs

ref_images_embeds = []
ip_adapter_images = []
app = FaceAnalysis(name="buffalo_l", providers=['CUDAExecutionProvider', 'CPUExecutionProvider'])
app.prepare(ctx_id=0, det_size=(640, 640))
image = cv2.cvtColor(np.asarray(image), cv2.COLOR_BGR2RGB)
faces = app.get(image)
ip_adapter_images.append(face_align.norm_crop(image, landmark=faces[0].kps, image_size=224))
image = torch.from_numpy(faces[0].normed_embedding)
ref_images_embeds.append(image.unsqueeze(0))
ref_images_embeds = torch.stack(ref_images_embeds, dim=0).unsqueeze(0)
neg_ref_images_embeds = torch.zeros_like(ref_images_embeds)
id_embeds = torch.cat([neg_ref_images_embeds, ref_images_embeds]).to(dtype=torch.float16, device="cuda")

clip_embeds = pipeline.prepare_ip_adapter_image_embeds(
 [ip_adapter_images], None, torch.device("cuda"), num_images, True)[0]

pipeline.unet.encoder_hid_proj.image_projection_layers[0].clip_embeds = clip_embeds.to(dtype=torch.float16)
pipeline.unet.encoder_hid_proj.image_projection_layers[0].shortcut = True # True if Plus v2

And I am getting:

AttributeError Traceback (most recent call last)

ValueError: not enough values to unpack (expected 2, got 1)

Sorry if I am missing something obvious. Here is my colab:

hi @juancopi81
docs are updated, you are not properly loading the weights, as all Face ID Plus models need a CLIP image encoder. See https://huggingface.co/docs/diffusers/using-diffusers/loading_adapters#ip-adapter-face-id-models or copy-paste the following snippet (you can find it in docs too):

from transformers import CLIPVisionModelWithProjection

image_encoder = CLIPVisionModelWithProjection.from_pretrained(
 "laion/CLIP-ViT-H-14-laion2B-s32B-b79K",
 torch_dtype=torch.float16,
)

pipeline = AutoPipelineForText2Image.from_pretrained(
 "runwayml/stable-diffusion-v1-5",
 image_encoder=image_encoder,
 torch_dtype=torch.float16
).to("cuda")

pipeline.load_ip_adapter("h94/IP-Adapter-FaceID", subfolder=None, weight_name="ip-adapter-faceid-plusv2_sd15.bin")

Thanks @fabiorigano!! Maybe adding that to this docs would be helpful? https://huggingface.co/docs/diffusers/main/en/using-diffusers/ip_adapter#face-model At least for me, it would have been helpful. If you think so, I could create a PR to add that.Thanks again!
