generate_text와 함께 외부 도구 사용

ai.google.dev에서 보기 Google Colab에서 실행 GitHub에서 소스 보기

일부 사용 사례에서는 특정 결과를 삽입하기 위해 모델에서 생성을 중지할 수 있습니다. 예를 들어 언어 모델은 단어 문제와 같은 복잡한 산술 문제를 다룰 수 없습니다. 이 튜토리얼에서는 외부 도구를 genai.generate_text 메서드와 함께 사용하여 단어 문제에 정답을 출력하는 예를 보여줍니다.

이 특정 예에서는 numexpr 도구를 사용하여 연산을 수행하지만 동일한 절차를 사용해 사용 사례에 맞는 다른 도구를 통합할 수 있습니다. 대략적인 단계는 다음과 같습니다.

  1. startend 태그를 확인하여 도구를 전송할 텍스트를 구분합니다.
  2. 결과에 태그를 사용하는 방법을 모델에 지시하는 프롬프트를 만듭니다.
  3. generate_text에 전달되는 stop_sequencesend 태그를 포함합니다.
  4. 모델 결과에서 start 태그와 end 태그 사이에 있는 텍스트를 도구에 대한 입력으로 가져옵니다.
  5. 도구를 실행하고 프롬프트에 출력을 추가합니다.
  6. 모델이 도구의 출력을 계속 사용하도록 generate_text를 다시 호출합니다.

직접 문제 해결하기

다음은 풀어볼 단어 문제입니다.

question = """
I have 77 houses, each with 31 cats.
Each cat owns 14 mittens, and 6 hats.
Each mitten was knit from 141m of yarn, each hat from 55m.
How much yarn was needed to make all the items?

그대로 사용해 보세요.

completion = generate_text(
    model=model,
    prompt=prompt_template.format(question=question),
    # The maximum length of the response
    max_output_tokens=800,
)

print(completion.result)
In the houses there are 77 * 31 = 2387 cats.
So they need 2387 * 14 = 33418 mittens.
And they need 2387 * 6 = 14322 hats.
In total they need 33418 * 141 + 14322 * 55 = 5554525m of yarn.
The answer: 5554525.

이 프롬프트는 일반적으로 잘못된 결과를 반환합니다. 일반적으로 단계는 정확하지만 산술이 잘못되었습니다.

답은 다음과 같습니다.

answer = 77*31*14*141 + 77*31*6*55
answer
5499648

모델에 계산기를 사용하라고 지시합니다.

다음 단계에서, 모델에 계산기에 액세스하는 방법에 대한 지침을 제공합니다. 그렇게 하려면 모델에서 계산이 필요한 위치를 나타내는 데 사용할 수 있는 startend 태그를 지정하면 됩니다. 프롬프트에 다음과 같은 내용을 추가합니다.

calc_prompt_template = """
You are an expert at solving word problems. Here's a question:

{question}

-------------------

When solving this problem, use the calculator for any arithmetic.

To use the calculator, put an expression between <calc></calc> tags.
The answer will be printed after the </calc> tag.

For example: 2 houses  * 8 cats/house = <calc>2 * 8</calc> = 16 cats

Work through it step by step, and show your work.
One step per line.

Your solution:
"""

calc_prompt = calc_prompt_template.format(question=question)

모델이 이 '계산기'의 출력에 액세스하도록 허용하려면 생성을 일시중지하고 결과를 삽입해야 합니다. stop_sequences 인수를 사용하여 </calc> 태그에서 중지합니다.

completion = generate_text(
    model=model,
    prompt=calc_prompt,
    stop_sequences=["</calc>"],
    # The maximum length of the response
    max_output_tokens=800,
    candidate_count=1,
)

result = completion.result
print(result)
In each house, there are <calc>31 * 14

stop_sequence는 결과에 포함되지 않습니다. 표현식을 분리하여 계산기를 실행하여 결과에 다시 추가합니다.

# Use re to clear units from the calculator expressions
import re
# Use numexpr since `eval` is unsafe.
import numexpr


def calculator(result):
  result, expression = result.rsplit('<calc>', 1)

  # Strip any units like "cats / house"
  clean_expression = re.sub("[a-zA-Z]([ /a-zA-Z]*[a-zA-Z])?",'', expression)

  # `eval` is unsafe use numexpr
  result = f"{result}<calc>{expression}</calc> = {str(numexpr.evaluate(clean_expression))}"
  return result
print(calculator(result))
In each house, there are <calc>31 * 14</calc> = 434

이제 이를 프롬프트에 추가하고 모델을 다시 실행하여 중단된 부분부터 이어서 진행할 수 있도록 합니다.

continue_prompt=calc_prompt +"\n"+ "-"*80 + "\n" + calculator(result)

completion = generate_text(
    model=model,
    prompt=continue_prompt,
    stop_sequences=["</calc>"],
    # The maximum length of the response
    max_output_tokens=800,
    candidate_count=1,
)

print(completion.result)
mittens.
In each house, there are <calc>31 * 6
