用swift量化错误

使用 swift export + gptq 量化 Qwen3-Reranker-4B 时，在 optimum.gptq 里遇到 layer_inputs[j] IndexError，是否目前不支持对 reranker 做 GPTQ？

IndexError: list index out of range

Reproduce the Qwen3-Reranker-4B Swift export with GPTQ, then trace the call through swift/llm/export/quant.py into optimum/gptq/quantizer.py where layer_inputs[j] raises IndexError. Check whether reranker models are supported by this path and verify completion of the export or a clear compatibility outcome.
