fetch_data_with_browser.tool_info = {
"tool_name": "browser_data_fetcher",
"tool_title": "使用浏览器",

"tool_params": [
{"name": "task_description", "description": "浏览器要执行的任务的描述。", "type": "string", "required": True}

}

tools = [fetch_data_with_browser]

Initialize Agent

agent = qwen_agent(
tools=tools,
debug=True,
log_level="debug",
log_file="example.log")

Run Agent

response = agent.run("Please search the weather in Shanghai.", stream=True)
full_response = ''
for chunk in response:
print(chunk, end="\n", flush=True)

     The `browser_use.Agent` requires the passed `llm` object to have a `.provider` attribute, but the `ChatOpenAI` instance (from `langchain_openai`) you provided does not have this attribute, which caused the error.

    Could you please share your `langchain_openai` version details? That will help me compare and identify any potential compatibility issues.
