LlamaIndex setup for running locally

Setup

Note

You can skip this page if you are interested in Colab notebooks only.

These are the instructions for local setup of the LlamaIndex-specific Python environment. A prerequisite is the general setup for running locally.

You should have a copy of this repository from the general local-run setup already. Go to the docs/frameworks/llamaindex subdirectory.

Create a Python 3.8+ virtual environment, activate it and install the required dependencies with:

pip install -r requirements_llamaindex.txt

Launch

Make sure you are in docs/frameworks/llamaindex and the virtual environment is active.

Source the API Key configuration with

. ../../../.api_keys

Now fire up Jupyter with:

jupyter notebook

and wait for a browser window to open with the notebooks in this directory, ready to run.

Database choice

The code looks for an Astra DB instance by default (as defined in the .env file at the root of this repo).

If you have a Cassandra cluster and want to use it instead, all you need is to replace the cassio.init(...) method call in the notebook cell and replace with something like:

cassio.init(
    session=...,
    keyspace=...,
)

provided you have created a cassandra.cluster.Session to your database and have a keyspace name (string).

See the "Further reading" section for more on using a local Cassandra.
