Toolkit for Chat API

Project description

基于 OpenAI API 的 Chat 对象,支持多轮对话,代理,以及异步处理数据等。

安装方法

pip install chattool --upgrade

使用方法

设置密钥和代理链接

通过环境变量设置密钥和代理,比如在 ~/.bashrc 或者 ~/.zshrc 中追加

export OPENAI_API_KEY="sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
export OPENAI_API_BASE="https://api.example.com/v1"
export OPENAI_API_BASE_URL="https://api.example.com" # 可选

或者在代码中设置:

import chattool
chattool.api_key = "sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
chattool.api_base = "https://api.example.com/v1"

注:环境变量 OPENAI_API_BASE 优先于 OPENAI_API_BASE_URL,二者选其一即可。

示例

示例1,多轮对话:

# 初次对话
chat = Chat("Hello, GPT-3.5!")
resp = chat.getresponse()

# 继续对话
chat.user("How are you?")
next_resp = chat.getresponse()

# 人为添加返回内容
chat.user("What's your name?")
chat.assistant("My name is GPT-3.5.")

# 保存对话内容
chat.save("chat.json", mode="w") # 默认为 "a"

# 打印对话历史
chat.print_log()

示例2,批量处理数据(串行),并使用缓存文件 chat.jsonl

# 编写处理函数
def data2chat(msg):
    chat = Chat()
    chat.system("你是一个熟练的数字翻译家。")
    chat.user(f"请将该数字翻译为罗马数字:{msg}")
    # 注意,在函数内获取返回
    chat.getresponse()
    return chat

checkpoint = "chat.jsonl" # 缓存文件的名称
msgs = ["1", "2", "3", "4", "5", "6", "7", "8", "9"]
# 处理数据,如果 checkpoint 存在,则从上次中断处继续
continue_chats = process_chats(msgs, data2chat, checkpoint)

示例3,批量处理数据(异步并行),用不同语言打印 hello,并使用两个协程:

from chattool import async_chat_completion, load_chats, Chat

langs = ["python", "java", "Julia", "C++"]
def data2chat(msg):
    chat = Chat()
    chat.user("请用语言 %s 打印 hello world" % msg)
    # 注意,这里不需要 getresponse 而交给异步处理
    return chat

async_chat_completion(langs, chkpoint="async_chat.jsonl", nproc=2, data2chat=data2chat)
chats = load_chats("async_chat.jsonl")

在 Jupyter Notebook 中运行,因其特殊机制,需使用 await 关键字和 wait=True 参数:

await async_chat_completion(langs, chkpoint="async_chat.jsonl", nproc=2, data2chat=data2chat, wait=True)

示例4,使用工具(自定义函数):

# 定义函数
def add(a: int, b: int) -> int:
    """
    This function adds two numbers.

    Parameters:
        a (int): The first number.
        b (int): The second number.

    Returns:
        int: The sum of the two numbers.
    """
    return a + b
# 传输函数
chat = Chat()
chat.setfuncs([add]) # 传入函数列表,可以是多个函数
chat.user("请计算 1 + 2")
# 自动调用工具
chat.autoresponse(display=True)

开源协议

这个项目使用 MIT 协议开源。
