في بعض حالات الاستخدام، قد تحتاج إلى إيقاف عملية الإنشاء من النموذج لإدراج نتائج معيّنة. على سبيل المثال، قد تواجه النماذج اللغوية مشكلة مع المسائل الحسابية المعقدة مثل المسائل الكلامية.
يعرض هذا الدليل التوجيهي مثالاً على استخدام أداة خارجية مع الطريقة genai.generate_text لإخراج الإجابة الصحيحة على مسألة كلمةية.
يستخدم هذا المثال بالتحديد أداة numexpr لإجراء العمليات الحسابية، ولكن يمكنك استخدام الإجراء نفسه لدمج أدوات أخرى خاصة بحالة الاستخدام. في ما يلي ملخّص للخطوات:
- حدِّد علامتَي
startوendلتعيين حدود النص لإرسال الأداة. - قم بإنشاء مطالبة لإرشاد النموذج حول كيفية استخدام العلامات في النتيجة.
- تضمين العلامة
endفيstop_sequencesالتي تم تمريرها إلىgenerate_text - استنادًا إلى نتيجة النموذج، استخدِم النص بين العلامتَين
startوendكإدخال في الأداة. - شغِّل الأداة وأضِف مخرجاتها إلى الإشعار.
- يمكنك الاتصال بـ "
generate_text" مرة أخرى لمواصلة عرض النموذج في نتائج الأداة.

I have 77 houses, each with 31 cats.

Each mitten was knit from 141m of yarn, each hat from 55m.
How much yarn was needed to make all the items?

التجربة كما هي:
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.
يتم عادةً عرض المطالبة كما هي نتيجة غير صحيحة. بشكل عام تكون الخطوات صحيحة لكن الحسابي خاطئ.
يجب أن تكون الإجابة:
answer = 77*31*14*141 + 77*31*6*55
answer
5499648
اطلب من النموذج استخدام آلة حاسبة.
في هذه المحاولة التالية، قدّم إرشادات النموذج حول كيفية الوصول إلى الآلة الحاسبة. يمكنك إجراء ذلك من خلال تحديد العلامة start وend التي يمكن للنموذج استخدامها للإشارة إلى الحالات التي يجب فيها إجراء عملية حسابية. أضِف طلبًا كما يلي إلى الطلب:
calc_prompt_template = """

-------------------
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.

calc_prompt = calc_prompt_template.format(question=question)
لمنح النموذج الإذن بالوصول إلى نتائج هذه "الآلة الحاسبة"، عليك إيقاف الإنشاء مؤقتًا وإدخال النتيجة. يمكنك استخدام الوسيطة stop_sequences للتوقف عند العلامة </calc>:
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
لم يتم تضمين stop_sequence في النتيجة. قسِّم التعبير وشغِّله من خلال الآلة الحاسبة، وأضِفه مرة أخرى إلى النتيجة:
# 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
عليك الآن إلحاق ذلك بالموجّه، وتشغيل النموذج مرة أخرى، حتى يمكن المتابعة من حيث توقف:
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
