Bu not defterinde, Google'ın en yeni büyük dil modellerine erişmenizi sağlayan PaLM API'yi kullanmaya nasıl başlayacağınızı öğreneceksiniz. Burada, PaLM API'nin metin oluşturma özelliklerini nasıl kullanacağınızı öğreneceksiniz.
Kurulum
Öncelikle PaLM API Python kitaplığını indirip yükleyin.
pip install -q google-generativeai
import pprint
import google.generativeai as palm
API Anahtarı Alma
Başlamak için bir API anahtarı oluşturmanız gerekir.
palm.configure(api_key='YOUR_API_KEY')
Metin oluşturma
Kullanılabilir modelleri bulmak için palm.list_models işlevini kullanın:
models = [m for m in palm.list_models() if 'generateText' in m.supported_generation_methods]
model = models[0].name
print(model)
models/text-bison-001
Metin oluşturmak için palm.generate_text yöntemini kullanın:
prompt = """
You are an expert at solving word problems.
Solve the following problem:
I have three houses, each with three cats.
each cat owns 4 mittens, and a hat. Each mitten was
knit from 7m of yarn, each hat from 4m.
How much yarn was needed to make all the items?
Think about it step by step, and show your work.
"""
completion = palm.generate_text(
model=model,
prompt=prompt,
temperature=0,
# The maximum length of the response
max_output_tokens=800,
)
print(completion.result)
There are 3 houses * 3 cats / house = 9 cats. So, 9 cats * 4 mittens / cat = 36 mittens were made. Also, 9 cats * 1 hat / cat = 9 hats were made. So, 36 mittens * 7m / mitten = 252m of yarn was used for the mittens. Also, 9 hats * 4m / hat = 36m of yarn was used for the hats. In total, 252m + 36m = 288m of yarn was used. Thus, the answer is 288.
Diğer seçenekler
palm.generate_text işlevinin bahsetmeye değer birkaç bağımsız değişkeni daha vardır.
Dizileri durdur
Oluşturma işlemini erken durdurmak için stop_sequences bağımsız değişkenini kullanın.
Örneğin, LLM'ler genellikle aritmetikte hata yapar. Denklemleri bir <calc> etiketine yerleştirerek modelden "hesap makinesi kullanmasını" isteyebilirsiniz.
İstemi düzenleyebilmek için modelin kapanış etiketinde durmasını sağlayın:
calc_prompt = f"""
Please solve the following problem.
{prompt}
----------------
Important: Use the calculator for each step.
Don't do the arithmetic in your head.
To use the calculator wrap an equation in <calc> tags like this:
<calc> 3 cats * 2 hats/cat </calc> = 6
----------------
"""
equation=None
while equation is None:
completion = palm.generate_text(
model=model,
prompt=calc_prompt,
stop_sequences=['</calc>'],
# The maximum length of the response
max_output_tokens=800,
)
try:
response, equation = completion.result.split('<calc>', maxsplit=1)
except Exception:
continue
print(response)
Chain-of-thought: There are three houses, and each house has three cats, so there are 3 houses * 3 cats / house = 9 cats. Each cat has 4 mittens, so the cats need 9 cats * 4 mittens / cat = 36 mittens. Each mitten takes 7m of yarn, so 36 mittens * 7m / mitten = 252m of yarn. Each cat has a hat, and each hat takes 4m of yarn, so 9 cats * 4m / cat = 36m of yarn. So, in total, 36m + 252m = 288m of yarn were needed. The answer should be
print(equation)
9 cats * 4 mittens / cat
Buradan sonucu hesaplayabilir ve modelin devam etmesi için yeni bir istem oluşturabilirsiniz. Tam bir çalışan uygulama için Metin hesap makinesi örneğini inceleyin.
Adaylar
Genellikle, LLM'ler tarafından oluşturulan metinde belirli bir rastgelelik derecesi vardır. (Bunun nedeni hakkında daha fazla bilgiyi LLM rehberi'nde bulabilirsiniz). Yani API'yi aynı girişle birden fazla kez çağırdığınızda farklı yanıtlar alabilirsiniz. Alternatif model yanıtları almak için bu özellikten yararlanabilirsiniz.
temperature bağımsız değişkeni, yanıtların varyansını kontrol eder. palm.Model nesnesi, temperature ve diğer parametreler için varsayılan değeri verir.
models[0]
Model(name='models/text-bison-001', base_model_id='', version='001', display_name='Text Bison', description='Model targeted for text generation.', input_token_limit=8196, output_token_limit=1024, supported_generation_methods=['generateText'], temperature=0.7, top_p=0.95, top_k=40)
candidate_count bağımsız değişkeni, döndürülen yanıtların sayısını kontrol eder:
completion = palm.generate_text(
model=model,
prompt=prompt,
# The number of candidates to return
candidate_count=8,
# Set the temperature to 1.0 for more variety of responses.
temperature=1.0,

print(completion.result)
In each house there are 3 cats * 4 mittens / cat = 12 mittens. In total there are 3 houses * 12 mittens / house = 36 mittens. In total there are 36 mittens * 7m / mitten = 252m of yarn for the mittens. In total there are 3 houses * 3 cats / house * 1 hat / cat = 9 hats. In total there are 9 hats * 4m / hat = 36m of yarn for the hats. In total there are 36m yarn for the hats + 252m yarn for the mittens = 288m of yarn. The answer: 288.
