干货！解决MindIE部署的DeepSeek-V3.2-Exp-W8A8不支持function call问题

一. 基础环境配置

请参考MindIE部署DeepSeek-V3.2-Exp

二. 问题描述

在上一篇MindIE部署DeepSeek-V3.2-Exp-W8A8中，我们成功地在两个Atlas 800IA2上部署了DeepSeek-V3.2-Exp-W8A8。但是在我测试function call的时候，发现模型返回的content完全不对，不论是流式推理（steam=true）还是非流式推理（stream=false）。以下是问题还原：

1. 非流式推理问题还原

使用如下request：

curl -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{
    "model": "ds-3.2",
    "messages": [
        {

        },
        {
            "role": "user",
            "content": "请问今天北京的天气怎么样？然后帮我设置一个明天上午10点的提醒，向邮件地址为10000发送邮件，邮件主题是开会，内容是开会。"

在经过chat_template之后，查看后台送入到大模型之前的token是什么样的：

<｜begin▁of▁sentence｜>You are a helpful customer support assistant. Use the supplied tools to assist the user.<｜User｜>请问今天北京的天气怎么样？然后帮我设置一个明天上午10点的提醒，向邮件地址为10000发送邮件，邮件主题是开会，内容是开会。<｜Assistant｜></think>

很明显，我在request里面定义了tools，但是经过chat_template之后，提示词里面完全没有了tools提示。所以这是tokenizer_config.json里面chat_template怎么写提示词的问题。

响应：

从响应中的content中也能看到，根本没有特殊token来显式地提取工具相关信息。

2. 流式推理问题还原

还是使用如下request（注意，指定stream=true）：

流式推理和非流式推理的问题是一样的。

3. 问题小结

  • 首先可以确定的是，当前的chat_template肯定是不支持function call了，所以要改tokenizer_config.json中的chat_template
  • 在上步之后，强制大模型按照chat_template指定的tool调用格式（特殊token）来返回结果，那么下一步就是怎么根据这些特殊token使用正则匹配来提取function name和function argument
  • 当前官方提供的MindIE镜像版本（2.2.T30-800I-A2-py311-openeuler24.03-lts-arm64）会不会存在bug

下面，我们开始按照上述思路去解决问题（我这里直接提供解决方法了，因为中间的问题调试、发现过程属实是漫长且复杂）。

三. 解决方案

3.1 非流式模式下的解决方法

3.1.1. 修改tokenizer_config.json中的chat_template

根据上面的分析，我们必须改动chat_template，让输入给大模型的提示词里面，包括我们提供的可调用的function，以及要指定大模型按照固定格式返回调用结果（只有固定格式（token），才能使用固定的正则匹配模板提取function）。
以下是改动的其中的一部分，这里提供截图：
在这里插入图片描述
这里打个广告，我自己搭建了一个资源平台，上面整理了我的一些自己的资源，只需要关注公众号登录即可获取相关资源。在这个平台上，我提供了写好了的tokenizer_config.json，欢迎获取！

使用上述tokenizer_config.json后，我们再次发送相同的request（问了说明问题，这里使用非流式），首先看大模型收到的输入token是啥样的：

 <｜begin▁of▁sentence｜>You are a helpful customer support assistant. Use the supplied tools to assist the user.
## Tools
You have access to the following tools:
### get_weather
Description: 获取指定城市的当前天气信息
Parameters: {"type": "object", "properties": {"location": {"type": "string", "description": "城市名称，例如：北京、上海"}, "unit": {"type": "string", "enum": ["celsius", "fahrenheit"], "description": "温度单位，摄氏度或华氏度"}}, "required": ["location"], "additionalProperties": false}
### send_email
Description: 发送电子邮件到指定收件人
Parameters: {"type": "object", "properties": {"recipient": {"type": "string", "description": "收件人的电子邮件地址"}, "subject": {"type": "string", "description": "邮件主题"}, "body": {"type": "string", "description": "邮件正文内容"}}, "required": ["recipient", "subject", "body"], "additionalProperties": false}
### get_stock_price
Description: 查询指定股票代码的当前价格
Parameters: {"type": "object", "properties": {"symbol": {"type": "string", "description": "股票代码，例如：AAPL（苹果公司）"}}, "required": ["symbol"], "additionalProperties": false}
### set_reminder
Description: 设置一个提醒，包括时间和内容
Parameters: {"type": "object", "properties": {"time": {"type": "string", "description": "提醒时间，格式为YYYY-MM-DD HH:MM"}, "message": {"type": "string", "description": "提醒内容"}}, "required": ["time", "message"], "additionalProperties": false}
IMPORTANT: ALWAYS adhere to this exact format for tool use:
<｜tool▁calls▁begin｜><｜tool▁call▁begin｜>tool_call_name<｜tool▁sep｜>tool_call_arguments<｜tool▁call▁end｜>{{additional_tool_calls}}<｜tool▁calls▁end｜>
Where:
- `tool_call_name` must be an exact match to one of the available tools
- `tool_call_arguments` must be valid JSON that strictly follows the tool's Parameters Schema
- For multiple tool calls, chain them directly without separators or spaces
<｜User｜>请问今天北京的天气怎么样？然后帮我设置一个明天上午10点的提醒，向邮件地址为10000发送邮件，邮件主题是开会，内容是开会。<｜Assistant｜></think>

可以看到，在使用新的tokenizer_config.json中的新的chat_template之后，提示词里面的内容和格式完全是我们想要的了。那么模型返回的是啥呢？看下响应：

{"id":"endpoint_common_15","object":"chat.completion","created":1762479066,"model":"ds-3.2","choices":[{"index":0,"message":{"role":"assistant","content":"<｜tool▁calls▁begin｜><｜tool▁call▁begin｜>get_weather<｜tool▁sep｜>{\"location\": \"北京\", \"unit\": \"celsius\"}<｜tool▁call▁end｜><｜tool▁calls▁begin｜><｜tool▁call▁begin｜>set_reminder<｜tool▁sep｜>{\"time\": \"2024-06-25 10:00\", \"message\": \"开会\"}<｜tool▁call▁end｜><｜tool▁calls▁begin｜><｜tool▁call▁begin｜>send_email<｜tool▁sep｜>{\"recipient\": \"10000\", \"subject\": \"开会\", \"body\": \"开会\"}<｜tool▁call▁end｜><｜tool▁calls▁begin｜>","tool_calls":null},"logprobs":null,"finish_reason":"stop"}],"usage":{"prompt_tokens":500,"completion_tokens":77,"total_tokens":577,"batch_size":[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1],"queue_wait_time":[5527,1239,762,1066,108,758,457,262,323,830,176,822,900,275,116,908,304,451,113,742,915,556,122,994,295,128,137,396,907,320,242,967,822,1094,878,273,447,206,361,355,997]},"prefill_time":378,"decode_time_arr":[93,43,43,42,42,41,41,41,41,44,44,42,42,41,41,43,43,46,46,87,44,44,42,42,44,44,44,44,48,48,42,42,41,41,42,42,42,42,47,47,43,43,42,42,41,41,82,41,41,41,41,42,42,42,42,41,41,43,43,43,43,45,45,43,43,42,42,42,42,43,43,46,46,44,44,84]}

可以看到content中返回的内容也是我们想要的内容，但是tool_calls还是为null，这就是解码部分的代码问题了，请看下一步。

3.1.2 修改镜像里面atb-model下面的源码

在处理这一步中的问题时，我是加了很多很多打印的log，这里不逐一写出分析步骤了，直接给出修改方案。

  1. 修改容器内的/usr/local/Ascend/atb-models/atb_llm/models/deepseekv2/tool_call_process_deepseekv2.py的tool_call_regex函数
vim /usr/local/Ascend/atb-models/atb_llm/models/deepseekv2/tool_call_process_deepseekv2.py

将tool_call_regex函数改为如下：

@property
    def tool_call_regex(self) -> Pattern:
        return re.compile(
         r'<｜tool▁calls▁begin｜><｜tool▁call▁begin｜>(\w+)<｜tool▁sep｜>(\{.*?\})<｜tool▁call▁end｜>'
         )
  1. 修改容器内的/usr/local/Ascend/atb-models/atb_llm/models/deepseekv2/tool_call_process_deepseekv2.py的get_tool_call_json函数
    将get_tool_call_json函数改为如下：
def get_tool_call_json(matches):
        tool_calls = []
        try:
            for match in matches:
                name, arguments = match
                tool_calls.append({"name": name, "arguments": arguments})
        except Exception:
            logger.error(f"Unable to parser matches")
            tool_calls = []
        return tool_calls

在改完chat_template和上述两个函数之后，我们再次发送request（非流式stream=false），看看响应是怎样的：

{"id":"endpoint_common_0","object":"chat.completion","created":1762480694,"model":"ds-3.2","choices":[{"index":0,"message":{"role":"assistant","content":"","tool_calls":[{"function":{"arguments":"{\"location\": \"北京\", \"unit\": \"celsius\"}","name":"get_weather"},"id":"call_nUjtaFXc","type":"function"},{"function":{"arguments":"{\"time\": \"2024-06-25 10:00\", \"message\": \"开会\"}","name":"set_reminder"},"id":"call_QdrUnIe9","type":"function"},{"function":{"arguments":"{\"recipient\": \"10000\", \"subject\": \"开会\", \"body\": \"开会\"}","name":"send_email"},"id":"call_4GikagXX","type":"function"}]},"logprobs":null,"finish_reason":"tool_calls"}],"usage":{"prompt_tokens":500,"completion_tokens":77,"total_tokens":577,"batch_size":[1,1,2,2,1,1,1,1,2,2,2,1,1,1,1,2,2,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1],"queue_wait_time":[5456,543,339872,345,1201,717,281,851,305214,1074,765,1190,1201,839,373,299501,425,629,848,437,174,104,812,131,959,1096,1135,584,876,1060,411,611,645,384,600,563,1143,1199,395,792,1040,1148]},"prefill_time":1634,"decode_time_arr":[61042,238,238,44,44,42,42,43,43,42,42,51,51,198,198,50,50,44,44,88,43,43,42,42,49,49,193,193,44,44,83,42,42,89,42,42,42,42,42,42,46,46,44,44,42,42,43,43,42,42,43,43,42,42,42,42,42,42,44,44,42,42,42,42,42,42,44,44,43,43,44,44,42,42,85,85]}

可以看到tool_calls中有内容了，并且调用的工具逻辑也正确。
此时我们看下流式下的输出是什么样的，流式响应：

data: {"id":"endpoint_common_6","object":"chat.completion.chunk","created":1762481940,"model":"ds-3.2","choices":[{"index":0,"delta":{"role":"assistant","content":""},"logprobs":null,"finish_reason":null}]}
data: {"id":"endpoint_common_6","object":"chat.completion.chunk","created":1762481941,"model":"ds-3.2","choices":[{"index":0,"delta":{"role":"assistant","content":""},"logprobs":null,"finish_reason":null}]}
data: {"id":"endpoint_common_6","object":"chat.completion.chunk","created":1762481944,"model":"ds-3.2","choices":[{"index":0,"delta":{"role":"assistant","content":""},"logprobs":null,"finish_reason":null}]}
data: {"id":"endpoint_common_6","object":"chat.completion.chunk","created":1762481944,"model":"ds-3.2","usage":{"prompt_tokens":500,"completion_tokens":77,"total_tokens":577,"batch_size":[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1],"queue_wait_time":[6178,294,158,1054,725,1099,1023,713,1059,219,894,963,708,927,472,513,573,334,251,1045,613,338,559,297,352,189,275,195,264,711,188,992,329,1166,884,1051,1228,731,370,993,384,1129]},"choices":[{"index":0,"delta":{"role":"assistant","content":""},"logprobs":null,"finish_reason":"tool_calls"}]}
data: [DONE]

很明显，即使正确改了非流式推理的function call，但是流式推理的结果还是不正确。

3.2 流式模型下的解决方法

3.2.1 修改tokenizer_config.json中的chat_template

这一步骤和3.1.1是一模一样的，换句话说，执行完3.1.1步骤后，这一步就不需要处理了。

3.2.2 修改镜像里面atb-model下面的源码

在调试的过程中发现，流式和非流式是走的两个分支，里面的逻辑不一样，且流式的解码更复杂。
在这里插入图片描述
这里不说问题原理了，直接给出解决方法。
修改/usr/local/Ascend/atb-models/atb_llm/models/base/tool_call_parser.py中的_decode_stream_tool_call_portion函数，找到图中位置，改成图中的代码。
在这里插入图片描述
在改完之后，我们再看下流式推理的响应：

data: {"id":"endpoint_common_0","object":"chat.completion.chunk","created":1762483136,"model":"ds-3.2","choices":[{"index":0,"delta":{"role":"assistant","content":""},"logprobs":null,"finish_reason":null}]}
data: {"id":"endpoint_common_0","object":"chat.completion.chunk","created":1762483197,"model":"ds-3.2","choices":[{"index":0,"delta":{"role":"assistant","tool_calls":[{"function":{"arguments":"{\"location\": \"北京\", \"unit\": \"celsius\"}"},"index":0}]},"logprobs":null,"finish_reason":null}]}
data: {"id":"endpoint_common_0","object":"chat.completion.chunk","created":1762483197,"model":"ds-3.2","choices":[{"index":0,"delta":{"role":"assistant","content":""},"logprobs":null,"finish_reason":null}]}
data: {"id":"endpoint_common_0","object":"chat.completion.chunk","created":1762483198,"model":"ds-3.2","choices":[{"index":0,"delta":{"role":"assistant","tool_calls":[{"function":{"arguments":"{\"time\": \"2024-06-25 10:00\", \"message\": \"开会\"}"},"index":1}]},"logprobs":null,"finish_reason":null}]}
data: {"id":"endpoint_common_0","object":"chat.completion.chunk","created":1762483199,"model":"ds-3.2","choices":[{"index":0,"delta":{"role":"assistant","tool_calls":[{"function":{"arguments":"{\"recipient\": \"10000\", \"subject\": \"开会\", \"body\": \"开会\"}"},"index":2}]},"logprobs":null,"finish_reason":null}]}
data: {"id":"endpoint_common_0","object":"chat.completion.chunk","created":1762483199,"model":"ds-3.2","usage":{"prompt_tokens":500,"completion_tokens":77,"total_tokens":577,"batch_size":[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1],"queue_wait_time":[5388,1029,728,591,702,602,484,490,978,418,491,777,362,224,565,159,425,397,398,768,1040,928,723,1013,781,457,203,890,1003,139,945,316,135,571,146,588,554,956,1078,1004,1081]},"choices":[{"index":0,"delta":{"role":"assistant","content":""},"logprobs":null,"finish_reason":"tool_calls"}]}
data: [DONE]

可以看到tool_calls中的逻辑是正确的。

四. 总结

感觉这个版本的镜像或者昇腾这一套还是有很多坑的，慢慢整吧。

我已经将我的/usr/local/Ascend/atb-models，atb-models源码（修正后）上传到了MindIE下的atb-model源码库（修正function call），下载好解压后，直接替换掉你的容器里面的/usr/local/Ascend/atb-models。
