LlamaIndex: call a calculator with a local model

The complete local starter uses Ollama llama3.1 to select a multiplication tool. Its 5,635,678 answer is the guide’s illustrative output. Install the model and integrations first; the source lists an approximately 32 GB RAM prerequisite.

入力例

import asyncio
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.ollama import Ollama


# Define a simple calculator tool
def multiply(a: float, b: float) -> float:
    """Useful for multiplying two numbers."""
    return a * b


# Create an agent workflow with our calculator tool
agent = FunctionAgent(
    tools=[multiply],
    llm=Ollama(
        model="llama3.1",
        request_timeout=360.0,
        # Manually set the context window to limit memory usage
        context_window=8000,
    ),
    system_prompt="You are a helpful assistant that can multiply two numbers.",
)


async def main():
    # Run the agent
    response = await agent.run("What is 1234 * 4567?")
    print(str(response))


# Run the agent
if __name__ == "__main__":
    asyncio.run(main())

LlamaIndex: inspect an author’s notebook graph preview

The author’s notebook graph preview illustrates an extracted network of entities and connections, with its original yFiles interface marks. Use the native image to inspect the overall structure. Graph-building follows the separate property-graph tutorial and its data/model prerequisites.

LlamaIndex: inspect the author’s Neo4j graph view

An original Neo4j capture shows the complete entity query below and its extracted graph. Truncated labels and imperfect generated relationships make it useful for inspecting extraction quality. The underlying essay and graph database belong to the source tutorial’s separate setup.
