AttributeError: 'str' object has no attribute 'usage'
🤖 AI解决方案
1. 误翻译
原文：
AttributeError: 'str' object has no attribute 'usage'
译文：
属性错误：‘str’对象没有‘usage’属性
2. 原因分析
usage属性，但该对象并非预期的响应对象（例如，它可能是一个简单的错误消息字符串或未经解析的原始响应）。autogen_ext/models/openai/_openai_client.py的第712行。代码逻辑如下：python
prompt_tokens=getattr(result.usage, "prompt_tokens", 0) if result.usage is not None else 0,
此处，
result被假设为一个具有.usage属性的对象（如OpenAI API的响应对象），但实际上它是一个字符串，因此访问result.usage引发了AttributeError。AssistantAgent调用语言模型（LLM）客户端生成回复的过程中。该客户端（model_client.create）返回了一个字符串，而非一个包含usage信息的完整对象。这通常意味着模型调用接口配置有误或返回了异常响应。3决方案
检查并修正模型客户端（
model_client）的配置，确保其指向一个能正确返回结构化对象（而非原始字符串）的API端点。以下是排查和修复步骤：python
# 确保你的模型客户端配置正确，例如使用OpenAI官方API
from autogen_ext.models.openai import OpenAIChatCompletionClient
model_client = OpenAIChatCompletionClient(
model="gpt-4", # 或其他正确模型名称
api_key="your-api-key",
# 如果使用自定义或代理端点，请检查URL是否正确且返回标准格式
# base_url="https://your-proxy-endpoint.com/v1"
)
如果需要快速定位问题，可以临时修改
autogen_ext/models/openai/_openai_client.py中的create方法（不推荐长期修改库文件）：python
# 在第712行附近，添加类型检查或异常捕获
try:
# 原有代码
prompt_tokens=getattr(result.usage, "prompt_tokens", 0) if result.usage is not None else 0,
except AttributeError as e:
print(f"模型返回结果类型异常，原始结果: {result}")
raise RuntimeError(f"模型客户端未返回有效响应对象: {e}") from e
独立测试你的API端点是否返回标准的JSON响应对象：
``
python
import requests
response = requests.post("your-api-endpoint", json={"model": "your-model", "messages": [{"role":"user", "content":"hi"}]})
print(response.json()) # 确认返回结构包含 usage 等字段
`4. 预防措施
先行测试：在将模型客户端集成到复杂工作流（如AutoGen群组聊天）前，编写一个独立的单元测试，验证 能正确返回带有usage`属性的对象。
