sam-audio-judge sam_audio branch still has mismatched config and weights

[Curry959]

Description

I followed the instructions from #46 and #23 to download the sam-audio-judge model from the sam_audio branch, but I'm still getting errors.

First, I encountered:

TypeError: SAMAudioJudgeConfig.__init__() got an unexpected keyword argument 'dac_vae_encoder'

After adding **kwargs to SAMAudioJudgeConfig.__init__() to bypass this, I now get:

RuntimeError: Error(s) in loading state_dict for SAMAudioJudgeModel:
Missing key(s) in state_dict: "data_proj.weight", "data_proj.bias", "audio_codec.encoder.block.0.bias", ...

Steps to Reproduce

1. Clone the sam-audio repo (main branch)
2. Download facebook/sam-audio-judge with --revision sam_audio
3. Run inference with sam-audio-large

Environment

• Python: 3.11
• sam-audio: Installed from source (main branch)
• Model: facebook/sam-audio-judge (sam_audio branch, downloaded on Feb 3, 2026)

Question

It seems the sam_audio branch of facebook/sam-audio-judge has been updated and is no longer compatible with the current codebase.

1. Is there an older version of the sam-audio-judge weights that works with the current code?
2. Or is there an updated version of the code that works with the new weights?

Thank you!

Thank you so much for sharing! I truly appreciate you coming back to provide this lead even after moving on from the project. I’ll head over to Hugging Face, download this version of model.safetensors, and see if it resolves the weight mismatch issue. I'll make sure to update the thread if I make any progress. Thanks again!

Didn't have time to dabble. I was scavenging again and came across this. https://huggingface.co/mrfakename/sam-audio-judge/blob/sam_audio/model.safetensors it appears to be an older copy, 2 months ago. Looks like this one can work as some of the missing keys are there. I tried searching for ""audio_codec.encoder.block.0.bias" didn't see that in there though. I don't have time to download and investigate this any further. — Reply to this email directly, view it on GitHub <#87 (comment)>, or unsubscribe <https://github.com/notifications/unsubscribe-auth/B5YSASZTTWAA5HP5WK7OYXL4KKG3TAVCNFSM6AAAAACTZZVJEOVHI2DSMVQWIX3LMV43OSLTON2WKQ3PNVWWK3TUHMZTQNJQGQ2TGMRXGU> .

it was a response to my post, that I deleted. I didn't think the message actually posted.
