Using Ollama with Curator

You can use Ollama as a backend for Curator to generate structured synthetic data. In this example, we will generate a list of countries and their capitals, but the approach can be adapted for any data generation task.

Prerequisites

• Python 3.10+

• Curator: Install via pip install bespokelabs-curator

• Ollama: Download via https://ollama.com/download

Steps

1. Create a curator.LLM subclass

Create a class that inherits from curator.LLM. Implement two key methods:

• prompt(): Generates the prompt for the LLM.

• parse(): Processes the LLM's response into your desired format.

Here’s the implementation:

from bespokelabs import curator
from pydantic import BaseModel, Field

class Location(BaseModel):
    country: str = Field(description="The name of the country")
    capital: str = Field(description="The name of the capital city")

class LocationList(BaseModel):
    locations: list[Location] = Field(description="A list of locations")

class SimpleOllamaGenerator(curator.LLM):
    response_format = LocationList

    def prompt(self, input: dict) -> str:
        return "Return five countries and their capitals."

    def parse(self, input: dict, response: str) -> dict:
        return [{"country": output.country, "capital": output.capital} for output in response.locations]

2. Configure the Ollama Backend

1. Start Ollama server with llama3.1:8bmodel.

ollama pull llama3.1:8b
ollama serve

1. Initialize your generator with Ollama configuration:

llm = SimpleOllamaGenerator(
    model_name="ollama/llama3.1:8b",  # Ollama model identifier
    backend_params={"base_url": "http://localhost:11434"},  # Ollama instance
)

3. Generate Data

Generate the structured data and output the results as a pandas DataFrame:

locations = llm()
print(locations.to_pandas())

Example Output

Using the above example, the output might look like this:

Country	Capital
France	Paris
Japan	Tokyo
Germany	Berlin
India	New Delhi
Brazil	Brasília

Ollama Configuration

Use base_url in the backend_params to specify the connection URL.

Example:

backend_params={"base_url": "http://localhost:11434"}
