问题是什么？

大家好！
我正在尝试使用requests库中的工具访问llama3-groq-tool-use:70b。以下是使用langchain==0.2.9的简单Python代码：

from langchain_core.tools import tool
from langchain_openai import ChatOpenAI
from langchain.prompts import (
    ChatPromptTemplate,
    MessagesPlaceholder,
)
from langchain.agents import AgentExecutor, create_openai_tools_agent

@tool
def function_1(a: int, b: int) -> int:
    """uses function function_1 for arguments a and b."""
    return a % b + 2

@tool
def function_2(a: int, b: int) -> int:
    """uses function function_2 for arguments a and b."""
    return a * b + 1

tools = [function_1, function_2]

llm = ChatOpenAI(
    model="llama3-groq-tool-use:70b",
    temperature=0,
)

default_prompt = ChatPromptTemplate.from_messages(
        [
            ("system", "You are a helpful AI assistant."),
            MessagesPlaceholder("chat_history", optional=True),
            ("human", "{input}"),
            MessagesPlaceholder("agent_scratchpad"),
        ]
    )

input_message = "What is function_1(10, 11)? Also what is function_2(10, 11)?"

agent = create_openai_tools_agent(
    llm=llm,
    tools=tools,
    prompt=default_prompt
)

agent_executor = AgentExecutor(
    agent=agent,
    tools=tools,
    verbose=True,
    return_intermediate_steps=False,
)

res = agent_executor.invoke({"input": input_message})

print(res)

结果如下：

> Entering new AgentExecutor chain...
<tool_call>
{"id": 0, "name": "function_1", "arguments": {"a": 10, "b": 11}}
</tool_call>
<tool_call>
{"id": 1, "name": "function_2", "arguments": {"a": 10, "b": 11}}
</tool_call>

> Finished chain.
{
    'input': 'What is function_1(10, 11)? Also what is function_2(10, 11)?',
    'output': '<tool_call>\n{"id": 0, "name": "function_1", "arguments": {"a": 10, "b": 11}}\n</tool_call>\n<tool_call>\n{"id": 1, "name": "function_2", "arguments": {"a": 10, "b": 11}}\n</tool_call>'
}

如果我使用langchain_community.chat_models.ollama.ChatOllama,输出也是一样的。
但是，如果我使用相同的模型(llama3-groq-70b-8192-tool-use-preview)并调用groq OpenAI兼容API,它会使用工具并调用函数，输出如下：

> Entering new AgentExecutor chain...

Invoking: `function_1` with `{'a': 10, 'b': 11}`

12
Invoking: `function_2` with `{'a': 10, 'b': 11}`

111The result of function_1(10, 11) is 12, and the result of function_2(10, 11) is 111.

> Finished chain.
{
    'input': 'What is function_1(10, 11)? Also what is function_2(10, 11)?',
    'output': 'The result of function_1(10, 11) is 12, and the result of function_2(10, 11) is 111.'
}

这是预期的行为还是这个问题仍在进行中？
