Pixart sigma model loading errors after update comfyui

[dalcefo]

There were no problem before, but i had update comfyui and ExtraModels node, then i got erroor like this.
Did I do something wrong? Or is there a problem with the extramodel code?

Error occurred when executing PixArtCheckpointLoader:

'EXM_PixArt_Model' object has no attribute 'diffusion_model'

Update ComfyUI itself, it should be fixed now.

I just had the same issue as the OP. Updated Comfy and the problem is still there. There's just no way to use Pixart, no matter what I try.

@Creepybits Did you do a fresh git pull?

[Creepybits]

I updated through manager. From which folder should I do git pull? I'm not very familiar with that.

@Creepybits Did you do a fresh git pull?

Nevermind, figured it out. I have done a git pull and it says everything is already up to date. The full error message I'm getting is this:

From your error:

File "C:\AI Stuff\ComfyUI\ComfyUI\comfy\model_base.py", line 97, in __init__ logging.info("model weight dtype {}, manual cast: {}".format(self.get_dtype(), self.manual_cast_dtype)) 

On the latest ComfyUI that line is completely different i.e. it shouldn't produce the error anymore. It was removed yesterday in this commit: comfyanonymous/ComfyUI@0a6b008

For some reason your local ComfyUI install isn't actually being updated.

Weird. Thanks though, All try to figure out why it doesn't update correctly then.

[city96]

Yeah, not sure what could cause that. What do you get when you run git status in the main ComfyUI folder (I assume C:\AI Stuff\ComfyUI\ComfyUI\)

Edit: also try update_comfyui.bat if you're on the standalone, assuming that's still a thing lol

I've just reinstalled comfy, and I get this from Git status

` PS C:\AI Stuff\ComfyUI\ComfyUI> git status
fatal: detected dubious ownership in repository at 'C:/AI Stuff/ComfyUI/ComfyUI'
'C:/AI Stuff/ComfyUI/ComfyUI' is owned by:

To add an exception for this directory, call:

    git config --global --add safe.directory 'C:/AI Stuff/ComfyUI/ComfyUI'

It seems to be working so far at least.

Hello, the PixArt checkpoint loader node is failing in ComfyUI with the following text:

Error occurred when executing PixArtCheckpointLoader:

Any suggestions on what could be going wrong? (ComfyUI is already updated)
Is it because I am trying to load the wrong model?

[city96]

@pallavnawani It looks like your ExtraModels repo isn't on the latest version. That line no longer has the current_device option there

After updating ComfyUI for SD35L, it appears that the t5_attention_mask attribute cannot be accessed in SD3ClipModel.
So the PixArt T5 from SD3 Clip, which outputs T5, cannot be used to input into the CLIP Text Encode, which previously worked.
I am using the T5xxl gguf text-encoder model.

This is the error.
'SD3ClipModel' object has no attribute 't5_attention_mask'

I checked the SD3ClipModel code for the versions v0.2.3 and v0.2.4.
The version for v0.2.4 has the t5_attention_mask attribute, which it was assigned during the object's initialisation, while the v0.2.3 does not have.

I will use an older version of ComfyUI instead separately.

[city96]

@doogyhatts should be good on both versions now, do a git pull on the extra models repo.

[doogyhatts]

Ok I found out what the error was now, after checking the latest sd.py.
It used "if clip_type == CLIPType.SD3:" as the conditional.
So I had to select 'sd3' as the type in the gguf clip loader, then it works again.
