Lance Context PyPI Example

This example demonstrates how to install the lance-context package (0.2.4 or newer) from PyPI and work with a context store using the Python API.

Setup

Ensure Python 3.11 or newer is available locally. This example runs directly from the src/ directory and only installs lance-context from PyPI.

Using uv

cd examples/pypi-basic
uv venv
source .venv/bin/activate
uv pip install "lance-context>=0.2.4"

Using pip

cd examples/pypi-basic
python -m venv .venv
source .venv/bin/activate
pip install "lance-context>=0.2.4"

Run the demo

python src/context_example/main.py

The script creates a Lance dataset under .artifacts/ (ignored by git) and appends a short travel-planning conversation. It prints the current version, demonstrates time-travel by checking out an earlier version, and shows how you can reopen the dataset path to continue appending in future runs.
