llama-index packs ollama_query_engine integration

Ollama Query Engine Pack

Create a query engine using completely local by Ollama

CLI Usage

You can download llamapacks directly using llamaindex-cli, which comes installed with the llama-index python package:

llamaindex-cli download-llamapack OllamaQueryEnginePack --download-dir ./ollama_pack

You can then inspect the files at ./ollama_pack and use them as a template for your own project.

Code Usage

You can download the pack to a the ./ollama_pack directory:

from llama_index.core.llama_pack import download_llama_pack

# download and install dependencies
OllamaQueryEnginePack = download_llama_pack(
    "OllamaQueryEnginePack", "./ollama_pack"
)

# You can use any llama-hub loader to get documents!
ollama_pack = OllamaQueryEnginePack(model="llama2", documents=documents)

From here, you can use the pack, or inspect and modify the pack in ./ollama_pack.

The run() function is a light wrapper around index.as_query_engine().query().

response = ollama_pack.run("What is the title of the book of John?")

You can also use modules individually.

# Use the llm
llm = ollama_pack.llm
response = llm.complete("What is Ollama?")

# Use the index directly
index = ollama_pack.index
query_engine = index.as_query_engine()
retriever = index.as_retriever()
