W niektórych przypadkach możesz chcieć zatrzymać generowanie modelu, aby wstawić określone wyniki. Na przykład modele językowe mogą mieć problemy ze skomplikowanymi zadaniami arytmetycznymi, takimi jak problemy słowne.
Ten samouczek pokazuje przykład użycia narzędzia zewnętrznego z metodą genai.generate_text do uzyskania poprawnej odpowiedzi na zadanie tekstowe.
W tym przykładzie użyliśmy narzędzia numexpr do wykonywania obliczeń arytmetycznych, ale w ten sam sposób możesz zintegrować inne narzędzia dopasowane do swojego przypadku użycia. Poniżej przedstawiamy przegląd kolejnych kroków:
- Określ tagi
startiend, aby rozróżnić tekst, który ma zostać wysłany do narzędzia. - Utwórz prompt instruujący model, jak używać tagów w wynikach.
- Uwzględnij tag
endw elemenciestop_sequencesprzekazywanym dogenerate_text. - Na podstawie wyniku modelu pobierz tekst znajdujący się między tagami
startiendjako dane wejściowe dla narzędzia. - Uruchom narzędzie i dodaj dane wyjściowe do promptu.
- Wywołaj ponownie funkcję
generate_text, aby model kontynuował dane wyjściowe narzędzia.

Spróbuj bezpośrednio rozwiązać problem
Oto zadanie słowne, które masz do rozwiązania:
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?
"""
prompt_template = """
You are an expert at solving word problems. Here's one:
{question}
Work through it step by step, and show your work.
One step per line.
Your solution:
"""
Spróbuj to zrobić w ten sposób:
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.
Prompt w takiej postaci, w jakiej zazwyczaj zwraca nieprawidłowy wynik. Zwykle kroki są poprawne, ale arytmetyczna błędna.
Odpowiedź powinna brzmieć:
answer = 77*31*14*141 + 77*31*6*55
answer
5499648
Poleć modelowi, aby użył kalkulatora
Przy następnej próbie przekaż modelowi instrukcje dostępu do kalkulatora. Możesz to zrobić, określając tagi start i end, których model może używać do wskazywania, gdzie są potrzebne obliczenia. Dodaj do promptu ten fragment:
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)
Aby przyznać modelowi dostęp do danych wyjściowych tego „kalkulatora”, musisz wstrzymać generowanie kodu i wstawić wynik. Aby zakończyć na tagu </calc>, użyj argumentu stop_sequences:
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
Wynik nie zawiera elementu stop_sequence. Podziel wyrażenie i przeprowadź je przez kalkulator, a następnie dodaj je z powrotem do wyniku:
# 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
Teraz dołącz to do promptu i ponownie uruchom model, aby kontynuować pracę od miejsca, w którym został wstrzymany:
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
Tym razem model kontynuował tekst z ostatniego obliczenia i przeszedł do następnego. Teraz wykonaj zadanie w pętli, aby w pełni rozwiązać zadanie tekstowe:
def solve(question=question):
results = []
for n in range(10):
prompt = calc_prompt_template.format(question=question)
prompt += " ".join(results)
completion = generate_text(
model=model,
prompt=prompt,
stop_sequences=["</calc>"],
# The maximum length of the response
max_output_tokens=800,
)
result = completion.result
if '<calc>' in result:
result = calculator(result)
results.append(result)
print('-'*40)
print(result)
if str(answer) in result:
break
if "<calc>" not in result:
break
is_good = any(str(answer) in r for r in results)
print("*"*100)
if is_good:
print("Success!")
else:
print("Failure!")
print("*"*100)
return is_good
solve(question);
