Bu hızlı başlangıç kılavuzu, Gemini API için Python SDK'nın nasıl kullanılacağını Google'ın büyük Gemini dil modellerine erişmenizi sağlar. Bu hızlı başlangıç kılavuzunda şunları öğreneceksiniz:

  1. Gemini'ı kullanmak için geliştirme ortamınızı ve API erişimini ayarlayın.
  2. Metin girişlerinden metin yanıtları oluşturun.
  3. Çok modlu girişlerden (metin ve resimler) metin yanıtları oluşturun.
  4. Çok dönüşlü sohbetler (sohbet) için Gemini'ı kullanın.
  5. Büyük dil modelleri için yerleştirmeleri kullanın.

Ön koşullar

Bu hızlı başlangıç kılavuzunu Google Colab, Bu not defterini doğrudan tarayıcıda çalıştıran ve yapılandırmalısınız.

Alternatif olarak, bu hızlı başlangıç kılavuzunu yerel olarak tamamlamak için geliştirme şu gereksinimleri karşılamasını sağlar:

  • Python 3.9+
  • Not defterini çalıştırmak için jupyter yüklemesi.

Kurulum

Python SDK'sını yükleyin

Gemini API için Python SDK'sı google-generativeai paketi. Bağımlılığı pip kullanarak yükleyin:

pip install -q -U google-generativeai

Paketleri içe aktarma

Gerekli paketleri içe aktarın.

import pathlib
import textwrap

import google.generativeai as genai

from IPython.display import display
from IPython.display import Markdown

def to_markdown(text):
  text = text.replace('•', '  *')
  return Markdown(textwrap.indent(text, '> ', predicate=lambda _: True))

# Used to securely store your API key
from google.colab import userdata

API anahtarınızı oluşturun

Gemini API'yi kullanabilmek için önce bir API anahtarı edinmeniz gerekir. Şu durumda: yoksa Google AI Studio'da tek tıklamayla anahtar oluşturun.

API anahtarı alma

Colab'de, anahtarı "🔑" bölümünün altında gizli anahtar yöneticisine ekleyin tıklayın. GOOGLE_API_KEY adını verin.

API anahtarınızı aldıktan sonra SDK'ya iletin. Bunu iki şekilde yapabilirsiniz:

  • Anahtarı, GOOGLE_API_KEY ortam değişkenine yerleştirin (SDK, otomatik olarak oradan teslim alır).
  • Anahtarı genai.configure(api_key=...) adlı cihaza geçirin
# Or use `os.getenv('GOOGLE_API_KEY')` to fetch an environment variable.
GOOGLE_API_KEY=userdata.get('GOOGLE_API_KEY')

genai.configure(api_key=GOOGLE_API_KEY)

Modelleri listeleyin

Artık Gemini API'yi çağırmaya hazırsınız. Mevcut öğeleri görmek için list_models kullanın Gemini modelleri:

Metin girişlerinden metin oluşturun

Yalnızca metin içeren istemler için Gemini 1.5 modelini veya Gemini 1.0 Pro modelini kullanın:

model = genai.GenerativeModel('gemini-1.5-flash')

generate_content yöntemi, aşağıdakiler de dahil olmak üzere çok çeşitli kullanım alanlarını ele alabilir: kullanılan modele bağlı olarak, birden çok dönüşlü sohbet ve çok modlu giriş destekler. Kullanılabilir modeller giriş olarak yalnızca metin ve resimleri ve metin destekler çıkış olarak kullanabilirsiniz.

En basit senaryoda, bir komut dizesini GenerativeModel.generate_content yöntem:

%%time
response = model.generate_content("What is the meaning of life?")

CPU times: user 110 ms, sys: 12.3 ms, total: 123 ms
Wall time: 8.25 s

Basit durumlarda tek ihtiyacınız response.text erişimcisidir. Göstermek için biçimlendirilmiş Markdown metni için to_markdown işlevini kullanın:

to_markdown(response.text)

The query of life's purpose has perplexed people across centuries, cultures, and continents. While there is no universally recognized response, many ideas have been put forth, and the response is frequently dependent on individual ideas, beliefs, and life experiences.

1.  **Happiness and Well-being:** Many individuals believe that the goal of life is to attain personal happiness and well-being. This might entail locating pursuits that provide joy, establishing significant connections, caring for one's physical and mental health, and pursuing personal goals and interests.

2.  **Meaningful Contribution:** Some believe that the purpose of life is to make a meaningful contribution to the world. This might entail pursuing a profession that benefits others, engaging in volunteer or charitable activities, generating art or literature, or inventing.

3.  **Self-realization and Personal Growth:** The pursuit of self-realization and personal development is another common goal in life. This might entail learning new skills, pushing one's boundaries, confronting personal obstacles, and evolving as a person.

4.  **Ethical and Moral Behavior:** Some believe that the goal of life is to act ethically and morally. This might entail adhering to one's moral principles, doing the right thing even when it is difficult, and attempting to make the world a better place.

5.  **Spiritual Fulfillment:** For some, the purpose of life is connected to spiritual or religious beliefs. This might entail seeking a connection with a higher power, practicing religious rituals, or following spiritual teachings.

6.  **Experiencing Life to the Fullest:** Some individuals believe that the goal of life is to experience all that it has to offer. This might entail traveling, trying new things, taking risks, and embracing new encounters.

7.  **Legacy and Impact:** Others believe that the purpose of life is to leave a lasting legacy and impact on the world. This might entail accomplishing something noteworthy, being remembered for one's contributions, or inspiring and motivating others.

8.  **Finding Balance and Harmony:** For some, the purpose of life is to find balance and harmony in all aspects of their lives. This might entail juggling personal, professional, and social obligations, seeking inner peace and contentment, and living a life that is in accordance with one's values and beliefs.

Ultimately, the meaning of life is a personal journey, and different individuals may discover their own unique purpose through their experiences, reflections, and interactions with the world around them.

 chef following a recipe. The recipe is like the program, and the chef's actions are like the instructions the computer follows. The chef reads the recipe (the program) and performs actions like gathering ingredients (fetching data from memory), mixing them together (performing calculations), and cooking them (processing data). The final dish (the output) is then presented on a plate (the computer screen).

In summary, a computer works by executing a series of instructions, stored in its memory, to perform calculations, make decisions, and display or store the results.

Örneğin, aynı konuyu paylaşan iki metin yaklaşımın benzer yerleştirmelere sahip olması gerekir. kosinüs benzerliği gibi matematiksel karşılaştırma tekniklerini kullanır. Proje yönetiminin ve neden yerleştirmeleri kullanmanız gerektiği hakkında daha fazla bilgi için Yerleştirmeler rehberini inceleyin.

Yerleştirmeleri oluşturmak için embed_content yöntemini kullanın. Yöntemde yerleştirme (task_type):

Görev Türü Açıklama
RETRIEVAL_QUERY Belirtilen metnin, arama/alma ayarındaki bir sorgu olduğunu belirtir.
RETRIEVAL_DOCUMENT Belirtilen metnin, arama/alma ayarındaki bir doküman olduğunu belirtir. Bu görev türünü kullanmak için title gereklidir.
SEMANTIC_SIMILARITY Belirtilen metnin Semantik Metin Benzerliği (STS) için kullanılacağını belirtir.
SINIFLANDIRMA Yerleştirmelerin sınıflandırma için kullanılacağını belirtir.
KÜMELEME Yerleştirmelerin kümeleme için kullanılacağını belirtir.

Aşağıda, belge almak amacıyla tek bir dize için bir yerleştirme oluşturulur:

result = genai.embed_content(
    model="models/embedding-001",
    content="What is the meaning of life?",
    task_type="retrieval_document",
    title="Embedding of single string")

    model="models/embedding-001",
    content=[
      'What is the meaning of life?',
      'How much wood would a woodchuck chuck?',
      'How does the brain work?'],
    task_type="retrieval_document",
    title="Embedding of list of strings")

# A list of inputs > A list of vectors output

prompt_feedback, istemi hangi güvenlik filtresinin engellediğini söyler:

response.prompt_feedback

safety_ratings {
  category: HARM_CATEGORY_SEXUALLY_EXPLICIT
  probability: NEGLIGIBLE
}
safety_ratings {
  category: HARM_CATEGORY_HATE_SPEECH

}
safety_ratings {
  category: HARM_CATEGORY_DANGEROUS_CONTENT
  probability: NEGLIGIBLE
}

Şimdi aynı istemi güvenlik ayarlarıyla modele sunun. sorunuza yanıt alabilirsiniz.

response = model.generate_content('[Questionable prompt here]',
                                  safety_settings={'HARASSMENT':'block_none'})
response.text

Ayrıca her adayın kendi safety_ratings bilgisinin (isteme göre) olduğunu unutmayın. başarılı olur ancak bireysel yanıtlar güvenlik kontrollerini geçemez.

Mesajları kodlama

Önceki bölümlerde, istem göndermenizi kolaylaştırmak için SDK kullanılıyordu. bağlantı kurmalısınız. Bu bölüm, öncekine ait tamamen yazılmış bir eşdeğeri sunar Böylece, teklifin ne kadar önemli olduğuna ilişkin alt düzey SDK, mesajları kodlar.

SDK, mesajınızı genai.protos.Content nesnesine dönüştürmeye çalışır. Her biri şunlardan birini içeren genai.protos.Part nesnenin listesini içerir:

  1. bir text (dize)
  2. inline_data (genai.protos.Blob); burada bir blob, data ve mime_type.
  3. veya diğer veri türlerini kapsar.

Ayrıca, bu sınıfların herhangi birini eşdeğer bir sözlük olarak da iletebilirsiniz.

Bu nedenle, önceki örnekteki tamamen yazılan eşdeğeri şu şekildedir:

model = genai.GenerativeModel('gemini-1.5-flash')
response = model.generate_content(
    genai.protos.Content(
        parts = [
            genai.protos.Part(text="Write a short, engaging blog post based on this picture."),
            genai.protos.Part(
                inline_data=genai.protos.Blob(
                    mime_type='image/jpeg',
                    data=pathlib.Path('image.jpg').read_bytes()
                )
            ),
        ],
    ),
    stream=True)

response.resolve()

Birden çok dönüşlü görüşmeler

Daha önce gösterilen genai.ChatSession sınıfı birçok kullanım alanını işleyebilir ancak varsayımlarda bulunmaktır. Kullanım alanınız bu sohbete uymuyorsa uygulanması durumunda, genai.ChatSession değerinin yalnızca bir sarmalayıcı olduğunu yaklaşık GenerativeModel.generate_content Tekli isteklere ek olarak birden çok dönüşlü konuşmaları da işleyebilir.

Tek tek mesajlar genai.protos.Content nesne veya uyumlu önceki bölümlerde göründüğü gibi. Sözlük olarak role ve parts anahtarları gerektirir. Bir ileti dizisindeki role şunlardan biri olabilir: İstemleri sağlayan user veya yanıtları sağlayan model.

genai.protos.Content nesne içeren bir liste iletirseniz şu şekilde ele alınır: çok dönüşlü sohbet:

model = genai.GenerativeModel('gemini-1.5-flash')

messages = [
    {'role':'user',
     'parts': ["Briefly explain how a computer works to a young child."]}

Imagine a computer as a really smart friend who can help you with many things. Just like you have a brain to think and learn, a computer has a brain too, called a processor. It's like the boss of the computer, telling it what to do.

Inside the computer, there's a special place called memory, which is like a big storage box. It remembers all the things you tell it to do, like opening games or playing videos.

When you press buttons on the keyboard or click things on the screen with the mouse, you're sending messages to the computer. These messages travel through special wires, called cables, to the processor.

The processor reads the messages and tells the computer what to do. It can open programs, show you pictures, or even play music for you.

All the things you see on the screen are created by the graphics card, which is like a magic artist inside the computer. It takes the processor's instructions and turns them into colorful pictures and videos.

To save your favorite games, videos, or pictures, the computer uses a special storage space called a hard drive. It's like a giant library where the computer can keep all your precious things safe.

And when you want to connect to the internet to play games with friends or watch funny videos, the computer uses something called a network card to send and receive messages through the internet cables or Wi-Fi signals.

So, just like your brain helps you learn and play, the computer's processor, memory, graphics card, hard drive, and network card all work together to make your computer a super-smart friend that can help you do amazing things!

At its core, a computer is a machine that can be programmed to carry out a set of instructions. It consists of several essential components that work together to process, store, and display information:

**1. Processor (CPU):**
   -   The brain of the computer.
   -   Executes instructions and performs calculations.
   -   Speed measured in gigahertz (GHz).
   -   More GHz generally means faster processing.

**2. Memory (RAM):**
   -   Temporary storage for data being processed.
   -   Holds instructions and data while the program is running.
   -   Measured in gigabytes (GB).
   -   More GB of RAM allows for more programs to run simultaneously.

**3. Storage (HDD/SSD):**
   -   Permanent storage for data.
   -   Stores operating system, programs, and user files.
   -   Measured in gigabytes (GB) or terabytes (TB).
   -   Hard disk drives (HDDs) are traditional, slower, and cheaper.
   -   Solid-state drives (SSDs) are newer, faster, and more expensive.

**4. Graphics Card (GPU):**
   -   Processes and displays images.
   -   Essential for gaming, video editing, and other graphics-intensive tasks.
   -   Measured in video RAM (VRAM) and clock speed.

**5. Motherboard:**
   -   Connects all the components.
   -   Provides power and communication pathways.

**6. Input/Output (I/O) Devices:**
   -   Allow the user to interact with the computer.
   -   Examples: keyboard, mouse, monitor, printer.

**7. Operating System (OS):**
   -   Software that manages the computer's resources.
   -   Provides a user interface and basic functionality.
   -   Examples: Windows, macOS, Linux.

When you run a program on your computer, the following happens:

1.  The program instructions are loaded from storage into memory.
2.  The processor reads the instructions from memory and executes them one by one.
3.  If the instruction involves calculations, the processor performs them using its arithmetic logic unit (ALU).
4.  If the instruction involves data, the processor reads or writes to memory.
5.  The results of the calculations or data manipulation are stored in memory.
6.  If the program needs to display something on the screen, it sends the necessary data to the graphics card.
7.  The graphics card processes the data and sends it to the monitor, which displays it.

This process continues until the program has completed its task or the user terminates it.
