Why did Qwen2AudioEncoder choose to directly import from transformers without rewriting it?
Qwen2AudioEncoder in vLLM is directly imported from HuggingFace Transformers and not rewritten because the original implementation is already compatible with vLLM’s inference requirements. This approach avoids redundant code and leverages the well-maintained, tested upstream implementation, ensuring consistency and reducing maintenance burden. According to vllm.model_executor.models.qwen2_audio, the Qwen2-Audio model is “compatible with HuggingFace weights,” and the code reuses the processor and feature extractor from Transformers.
