国内使用ChatGPT
访问ChatGPT困难重重，特别是调用其API，想付费都无比艰难。所以这里推荐去申请微软的Azure（portal.azure.com/）里面的大语言模型，可以用国内的信用卡按量付费。
里面关键是进入“模型部署”部署模型，然后去“密钥和终结点”找到自己的密钥和终结点。
首先要安装python-dotenv和openai模块。使用python-dotenv库来读取.env文件初始化环境变量。
!pip install python-dotenv
!pip install openai
在你的项目目录中创建一个.env文件，并将你的OpenAI API密钥、终结点（在“密钥和终结点”里面找）等添加到该文件中。这里.env文件的概念和Docker Compose用的.env文件是一样的。
.env文件的内容如下：
OPENAI_API_BASE=https://endpoint.openai.azure.com/ #终结点
OPENAI_API_KEY=youropenapikey #密钥
OPENAI_API_TYPE=azure
OPENAI_API_VERSION=2023-07-01-preview
使用以下代码加载.env文件中的环境变量：
import openai
from dotenv import load_dotenv, find_dotenv
load_dotenv(find_dotenv()) # read local .env file
deployment = "gpt-35-turbo" # 就是上面的部署名
model = "gpt-3.5-turbo"
通过直接调用Api的方式来进行文本翻译
我们先通过“传统”的调用Api的方式来完成程序的功能：将海盗英语翻译成“优雅尊重的美式英语”。
def get_completion(prompt, model="gpt-3.5-turbo", engine="gpt-35-turbo"):
messages = [{"role": "user", "content": prompt}]
response = openai.ChatCompletion.create(
model=model,
engine=engine, #使用Azure的GPT-3.5模型要用这个
messages=messages,
temperature=0,
)
return response.choices[0].message["content"]
customer_email = """
Arrr, I be fuming that me blender lid \
flew off and splattered me kitchen walls \
with smoothie! And to make matters worse,\
the warranty don't cover the cost of \
cleaning up me kitchen. I need yer help \
right now, matey!
"""
style = """American English in a calm and respectful tone"""
prompt = f"""Translate the text \
that is delimited by triple backticks
into a style that is {style}.
text: ```{customer_email}```
"""
print(prompt)
response = get_completion(prompt)
print(response)
这里使用Python的fstring来实现提示的“参数化”。在Python世界，fstring很常用，就是多了个f感觉不太美观，不如直接用groovy的gstring的形式。
最终传给模型的Prompt是这样的：
Translate the text that is delimited by triple backticks
into a style that is American English in a calm and respectful tone.
text: \```
Arrr, I be fuming that me blender lid flew off and splattered me kitchen walls with smoothie! And to make matters worse,the warranty don't cover the cost of cleaning up me kitchen. I need yer help right now, matey!
\```
这里采用了一个小技巧来明确告诉模型要翻译的文本：把翻译的文本用三重引号（triple backticks）来括住。
模型运行返回了很漂亮的英语：I'm really frustrated that my blender lid flew off and made a mess of my kitchen walls with smoothie! And to add to my frustration, the warranty doesn't cover the cost of cleaning up my kitchen. I could really use your help at this moment, my friend.
