When does this happen?

IF When loading GLM-4.5-FP8 or similar models that require embedding support, the UnquantizedLinearMethod class raises NotImplementedError because it lacks the 'embedding' method.

How others solved it

THEN Apply the fix from PR #22257 (https://github.com/vllm-project/vllm/pull/22257) which adds the missing 'embedding' method to UnquantizedLinearMethod, or upgrade to a vLLM version that includes this fix (e.g., >0.10.0).

In the class definition, add: def embedding(self, *args, **kwargs): return self.linear(*args, **kwargs) or similar forwarding logic as per the PR.
