apply_chat_template api usage consult

[FanZhang91]

       ` environment: transformers=4.42.4, tokenizers=0.19.1`
        I want to use apply_chat_template interface to implement tools calling。 Using the tools parameter to pass in function information, but the return result of the `apply_chat_template `interface does not add input tools info to the generated prompt.
        how to fix this problem? Here is the code I used。

from transformers import AutoTokenizer

get_current_weather = {
  "type": "function",
  "function": {
    "name": "get_current_weather",
    "description": "Get the current weather in a given location.",
    "parameters": {
        "type": "object",
        "properties": {
          "location": {
            "type": "string",
            "description": "The city and state, e.g. San Francisco, CA",
          },
          "unit": {"type": "string", "enum": ["celsius", "fahrenheit"]},
        },
        "required": ["location"],
      },
  }
}

messages = [
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "help me query currnet weather in San Francisco."},
    ]

tokenizer = AutoTokenizer.from_pretrained("xxxx/Qwen2-1.5B-Instruct")

prompt = tokenizer.apply_chat_template(
    messages,
    tools=[get_current_weather,],
    tokenize=False,
    add_generation_prompt=True,
)

print("prompt: ", prompt)

prompt:  <|im_start|>system
You are a helpful assistant.<|im_end|>
<|im_start|>user
help me query currnet weather in San Francisco.<|im_end|>
<|im_start|>assistant
