Integration package connecting ObjectBox and LangChain

langchain-objectbox

About

This package contains the ObjectBox integrations for LangChain.

Development Notes

Setup

Poetry

Should be installed isolated from rest of system and project's venv (see also https://python-poetry.org/docs/#installation)

# Debian-based Setup of poetry (should be external to venv)
apt-get install -y pipx
pipx install poetry

Ensure your $HOME/.local/bin is in $PATH.

Tox

pipx install tox

Initial Package Setup

mkdir -p libs/objectbox  # more-or-less blueprinted from other `langchain-<ext>` python projects
cd libs/objectbox
poetry init # answered some questions, added deps: langchain-core, objectbox
poetry add -G test pytest
python3 -m venv .venv
source .venv/bin/activate
poetry install
poetry add -G test langchain

• From objectbox-langchain/libs/community, copied
  • langchain_community/vectorstores/objectbox.py to langchain_objectbox/vectorstores.py
  • tests/integration_tests/vectorstores/test_objectbox.py to tests/integration_tests/test_objectbox.py
    • Deactivated integration tests that use HuggingFace... TODO: Can we have simpler Embeddings (it wanted to download nvidia packages, can ollama be an option here?)
