Last version of ComfyUI break PuLID :

For a quick fix, find the file comfy/ldm/flux/model.py in your installation (this is the file to which the error message refers) and replace this line (also mentioned in the error message):

        out = self.forward_orig(img, img_ids, context, txt_ids, timestep, y, guidance, control, transformer_options, attn_mask=kwargs.get("attention_mask", None))

with

        out = self.forward_orig(img, img_ids, context, txt_ids, timestep, y, guidance, control, transformer_options)

Restart ComfyUI and the error should no longer appear (and apparently the generation still works as expected).

UmeAiRT PuLID simple workflow

Today I'd like to share with you a slightly more specific workflow.

PuLID allows you to create images of a person from a single photo!

I've written a complete guide to its use: Step-by-Step Guide Series: ComfyUI - PuLID | Civitai

How to install

Automatic

The prerequisites are a little more complex than usual, but the easiest way to install the necessary nodes is to use my "add missing node script" or "ComfyUI auto installer".

Manual
