[Gao и др., (2022)](https://arxiv.org/abs/2211.10435) представляют метод, который использует LLM-модели для чтения проблем естественного языка и генерации программ в качестве промежуточных шагов рассуждения. Названные "program-aided language models" (PAL), они отличаются от цепочки мыслей в том, что вместо использования свободного текста для получения решения они передают этот шаг решения в программное окружение, такое как интерпретатор Python.

Давайте рассмотрим пример с использованием LangChain и OpenAI GPT-3. Мы заинтересованы в разработке простого приложения, которое способно интерпретировать заданный вопрос и предоставлять ответ, используя интерпретатор Python.
|
|
|
|
|
|
Конкретно, нас интересует создание функциональности, позволяющей использовать LLM для ответов на вопросы, требующие понимания даты. Мы предоставим LLM подсказку, которая включает несколько образцов, взятых [отсюда](https://github.com/reasoning-machines/pal/blob/main/pal/prompt/date_understanding_prompt.py).
|
|
|
|
|
|
Вот импорты, которые нам понадобятся:
|
|
|
|
|
|
```python
|
|
|
import openai
|
|
|
from datetime import datetime
|
|
|
from dateutil.relativedelta import relativedelta
|
|
|
import os
|
|
|
from langchain.llms import OpenAI
|
|
|
from dotenv import load_dotenv
|
|
|
```
|
|
|
|
|
|
Давайте сначала настроим несколько вещей:
|
|
|
|
|
|
```python
|
|
|
load_dotenv()
|
|
|
|
|
|
# API configuration
|
|
|
openai.api_key = os.getenv("OPENAI_API_KEY")
|
|
|
|
|
|
# for LangChain
|
|
|
os.environ["OPENAI_API_KEY"] = os.getenv("OPENAI_API_KEY")
|
|
|
```
|
|
|
|
|
|
Настройка экземпляра модели:
|
|
|
|
|
|
```python
|
|
|
llm = OpenAI(model_name='text-davinci-003', temperature=0)
|
|
|
```
|
|
|
|
|
|
Настройка подсказки + вопроса:
|
|
|
|
|
|
```python
|
|
|
question = "Today is 27 February 2023. I was born exactly 25 years ago. What is the date I was born in MM/DD/YYYY?"
|
|
|
|
|
|

|
|
|
# Q: 2015 is coming in 36 hours. What is the date one week from today in MM/DD/YYYY?
|

|
|
|
today = datetime(2015, 1, 1) - relativedelta(hours=36)
|
|
|
# One week from today,

|
# Q: Jane was born on the last day of Feburary in 2001. Today is her 16-year-old birthday. What is the date yesterday in MM/DD/YYYY?
|
|
|
# If Jane was born on the last day of Feburary in 2001 and today is her 16-year-old birthday, then today is 16 years later.
|
|
|
today = datetime(2001, 2, 28) + relativedelta(years=16)
|
|
|
# Yesterday,
|
|
|
yesterday = today - relativedelta(days=1)
|
|

|
|
|
# Q: {question}

""".strip() + '\n'
|
|
|
```
|
|
|
|
|
|
```python
|
|
|
llm_out = llm(DATE_UNDERSTANDING_PROMPT.format(question=question))
|
|
|
print(llm_out)
