Problems using Ollama embeddings

General
1

I have created a tool for RAG in a text file with the following configuration:

from crewai_tools import (
    TXTSearchTool,      # This tool has problems
    ScrapeWebsiteTool,
    SeleniumScrapingTool
)

# ...

txt_tool = TXTSearchTool(
    txt='/home/pepo/working/MyFile.txt',
    config=dict(
        llm=dict(
            provider="ollama",
            config=dict(
                model="llama3.2",
                temperature=0.5,
                stream=False,
            ),
        ),
        embedder=dict(
            provider="ollama",
            config=dict(
                model="nomic-embed-text",
                # task_type="retrieval_document",
                # title="Embeddings",
            ),
        ),
    )
)

# ...

    @agent
    def my_agent(self) -> Agent:
        return Agent(
                config=self.agents_config['my_agent'],
                verbose=True,
                tools=[txt_tool]
            )

I run the application

crewai run

But I get an error telling me that the libraries are incomplete:

ImportError: Ollama requires extra dependencies. Install with `pip install ollama`
An error occurred while running the crew: Command '['uv', 'run', 'run_crew']' returned non-zero exit status 1.

How can I fix this issue? or How do I install (internally) the library since Ollama is installed in the environment?

I’m using a venv environment, I entered the environment and placed the following command:

crewai update

Then I installed the package:

uv add ollama

And voila, I’m apparently using the “embeddings”
