Source Code

"""This is the langchain_ollama package.

Provides infrastructure for interacting with the [Ollama](https://ollama.com/)
service.

!!! note
    **Newly added in 0.3.4:** `validate_model_on_init` param on all models.
    This parameter allows you to validate the model exists in Ollama locally on
    initialization. If set to `True`, it will raise an error if the model does not
    exist locally. This is useful for ensuring that the model is available before
    attempting to use it, especially in environments where models may not be
    pre-downloaded.
