目前分析处于 async def _achat_completion_stream(self, messages: list[dict], timeout=USE_CONFIG_TIMEOUT) -> str: response: AsyncStream[ChatCompletionChunk] = wait self.aclient.chat.completions.create( **self._cons_kwargs(messages) 、 timeout=self.get_timeout(timeout))、stream=True )usage = Nonecollected_messages = [] async for chunk in response: chunk_message = chunk.choices[0].delta.content 或 "" if chunk.choices else "" # 提取消息 finish_reason = ( chunk.choices[0].finish_reason if chunk.choices and hasattr(chunk.choices[0], "finish_reason") else None ) log_llm_stream(chunk_message)collected_messages.append(chunk_message) if finish_reason: if hasattr（块，“用法”）：

某些服务将用途作为块的属性，例如 Fireworks

                usage = CompletionUsage(**chunk.usage)
            elif hasattr(chunk.choices[0], "usage") :
                # The usage of some services is an attribute of chunk.choices[0], such as Moonshot
                usage = CompletionUsage(**chunk.choices[0].usage)
            elif "openrouter.ai" in self.config.base_url:
                # due to it get token cost from api
                usage = await get_openrouter_tokens(chunk)

中的if hasattr(chunk, "usage")和elif hasattr(chunk.choices[0], "usage")没有判空导致的

我有一个问题

aa875982361

是的，我对 metagpt version=0.8.1 有同样的问题，在我使用 pip install metagpt==0.7.1 后也再次发生

huangpan2507

我也是。错误报告 #1250
