deepseek本地部署及java、python調(diào)用步驟詳解

更新時(shí)間：2025年02月15日 10:19:46 作者：Most666

這篇文章主要介紹了如何下載和使用Ollama模型,包括安裝JDK?17及以上版本和Spring?Boot?3.3.6,配置pom文件和application.yml,創(chuàng)建Controller,以及使用Python調(diào)用模型,需要的朋友可以參考下

1.下載Ollama

(需要科學(xué)上網(wǎng))

https://ollama.com/

2.拉取模型

輸入命令

ollama pull deepseek-v3

由于v3太大，改為r1，命令為：

ollama run deepseek-r1:1.5b

查看安裝的模型

ollama ls

查看啟動(dòng)的模型

ollama ps

對(duì)話框輸入/bye退出

3.Java調(diào)用

目前僅支持jdk17以上版本使用，本文使用的是jdk21，springboot版本為3.3.6版本過高、過低時(shí)都無法正常啟動(dòng)

3.1引入pom

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

3.2配置application.yml

server:
  port: 8088
spring:
  application:
    name: demo21
  ai:
    ollama:
      base-url: http://localhost:11434
      chat:
        options:
          model: deepseek-r1:1.5b

3.2創(chuàng)建Controller

import org.springframework.ai.chat.ChatResponse;
import org.springframework.ai.chat.prompt.Prompt;
import org.springframework.ai.ollama.OllamaChatClient;
import org.springframework.ai.ollama.api.OllamaOptions;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class OllamaClientController {

    @Autowired
    @Qualifier("ollamaChatClient")
    private OllamaChatClient ollamaChatClient;

    /**
     * http://localhost:8088/ollama/chat/v1?msg=java就業(yè)前景
     */
    @GetMapping("/ollama/chat/v1")
    public String ollamaChat(@RequestParam String msg) {
        return this.ollamaChatClient.call(msg);
    }

    /**
     * http://localhost:8088/ollama/chat/v2?msg=java就業(yè)前景
     */
    @GetMapping("/ollama/chat/v2")
    public Object ollamaChatV2(@RequestParam String msg) {
        Prompt prompt = new Prompt(msg);
        ChatResponse chatResponse = ollamaChatClient.call(prompt);
        return chatResponse.getResult().getOutput().getContent();
    }

    /**
     * http://localhost:8088/ollama/chat/v3?msg=java就業(yè)前景
     */
    @GetMapping("/ollama/chat/v3")
    public Object ollamaChatV3(@RequestParam String msg) {
        Prompt prompt = new Prompt(
                msg,
                OllamaOptions.create()
                        .withModel("deepseek-r1:1.5b")
                        .withTemperature(0.4F));
        ChatResponse chatResponse = ollamaChatClient.call(prompt);
        return chatResponse.getResult().getOutput().getContent();
    }
}

4.python調(diào)用

pip引入

pip install ollama

創(chuàng)建.py文件

import ollama

# 流式輸出
def api_generate(text: str):
    print(f'提問：{text}')

    stream = ollama.generate(
        stream=True,
        model='deepseek-r1:1.5b',
        prompt=text,
    )

    print('-----------------------------------------')
    for chunk in stream:
        if not chunk['done']:
            print(chunk['response'], end='', flush=True)
        else:
            print('\n')
            print('-----------------------------------------')
            print(f'總耗時(shí)：{chunk['total_duration']}')
            print('-----------------------------------------')

def api_chat(text: str):
    print(f'提問：{text}')

    stream = ollama.chat(
        stream=True,
        model='deepseek-r1:1.5b',
        messages=[{"role":"user","content":text}]
    )

    print('-----------------------------------------')
    for chunk in stream:
        if not chunk['done']:
            print(chunk['message'].content, end='', flush=True)
        else:
            print('\n')
            print('-----------------------------------------')
            print(f'總耗時(shí)：{chunk['total_duration']}')
            print('-----------------------------------------')

if __name__ == '__main__':
    # 流式輸出
    api_generate(text='python就業(yè)前景')
    
    api_chat(text='python就業(yè)前景')

    # 非流式輸出
    content = ollama.generate(model='deepseek-r1:1.5b', prompt='python就業(yè)前景')
    print(content)

    content = ollama.chat(model='deepseek-r1:1.5b', messages=[{"role":"user","content":'python就業(yè)前景'}])
    print(content)
