Esercizio pratico interattivo

Prova a risolvere questo esercizio completando il codice di esempio.

# Complete the prompt for formatting answers
example_prompt = PromptTemplate.from_template("Question: {____}\n{____}")

# Create the few-shot prompt
prompt_template = ____(
    examples=____,
    example_prompt=____,
    suffix="Question: {input}",
    input_variables=["____"],
)

prompt = prompt_template.invoke({"input": "What is Jack's favorite technology on DataCamp?"})
print(prompt.text)

Welcome to the LangChain framework for building applications on LLMs! You'll learn about the main components of LangChain, including models, chains, agents, prompts, and parsers. You'll create chatbots using both open-source models from Hugging Face and proprietary models from OpenAI, create prompt templates, and integrate different chatbot memory strategies to manage context and resources during conversations.

Exercise 1: L'ecosistema LangChain Exercise 2: Modelli OpenAI in LangChain!Exercise 3: Modelli Hugging Face in LangChain!Exercise 4: Modelli di prompt Exercise 5: Prompt template e concatenazione Exercise 6: Template di prompt per chat Exercise 7: Suggerimento di pochi colpi Exercise 8: Creare un set di esempi di pochi scatti Exercise 9: Creare il template di few-shot prompting

Exercise 10: Implementare il few-shot prompting

Time to level up your LangChain chains! You'll learn to use the LangChain Expression Language (LCEL) for defining chains with greater flexibility. You'll create sequential chains, where inputs are passed between components to create more advanced applications. You'll also begin to integrate agents, which use LLMs for decision-making.

Exercise 1: Sequential chains Exercise 2: Building prompts for sequential chains Exercise 3: Sequential chains with LCEL Exercise 4: Introduction to LangChain agents Exercise 5: What's an agent?Exercise 6: ReAct agents Exercise 7: Custom tools for agents Exercise 8: Defining a function for tool use Exercise 9: Creating custom tools Exercise 10: Integrating custom tools with agents

One limitation of LLMs is that they have a knowledge cut-off due to being trained on data up to a certain point. In this chapter, you'll learn to create applications that use Retrieval Augmented Generation (RAG) to integrate external data with LLMs. The RAG workflow contains a few different processes, including splitting data, creating and storing the embeddings using a vector database, and retrieving the most relevant information for use in the application. You'll learn to master the entire workflow!
