Installation¶

Python Version¶

PyGraphDB targets Python 3.9 through 3.13. The LevelDB backend uses plyvel; at the time of writing, plyvel wheels are not available for Python 3.14 or free-threaded Python builds. Use Python 3.12 or 3.13 for notebooks that need the LevelDB backend.

Install With uv¶

From a local checkout:

uv sync

For editable development:

uv add --editable /path/to/pygraphdb

Install optional features only when you need them:

uv add "/path/to/pygraphdb[lmdb,msgpack,protobuf]"
uv add "/path/to/pygraphdb[leveldb]"
uv add "/path/to/pygraphdb[fast-ingest]"

Install With pip¶

python -m venv .venv
. .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install .

Install optional backends and serializers:

python -m pip install ".[lmdb]"
python -m pip install ".[leveldb]"
python -m pip install ".[rocksdb]"
python -m pip install ".[fast-ingest]"
python -m pip install ".[msgpack,protobuf]"
python -m pip install ".[all]"

Install From GitHub¶

python -m pip install "pygraphdb[all] @ git+https://github.com/mylonasc/pygraphdb.git"

Notebook Kernel Example¶

Use a Python version supported by your selected backend and register it with Jupyter:

uv python install 3.12
uv venv --python 3.12
uv sync --extra leveldb --extra lmdb --extra msgpack --extra protobuf
uv add --dev ipykernel
.venv/bin/python -m ipykernel install --user --name pygraphdb-py312 --display-name "PyGraphDB Python 3.12"

Optional Dependencies¶

lmdb: LMDB key-value backend.
leveldb: LevelDB key-value backend through plyvel.
rocksdb: RocksDB key-value backend through pyrex-rocksdb>=0.3.0a0.
arrow: Arrow array support through pyarrow for columnar ingestion helpers.
polars: Polars DataFrame support for columnar ingestion helpers.
fast-ingest: Convenience extra for pyarrow, polars, and pyrex-rocksdb>=0.3.0a0.
msgpack: MessagePack serializer.
protobuf: Protobuf Struct serializer for JSON-like dictionaries.
bloom: Bloom-filter support through pybloom-live.
docs: Sphinx documentation build dependencies.

Pre-Release Installs¶

Alpha releases use standard Python pre-release versions, for example 0.2.0a0. If a stable release with the same base version exists in the future, install alpha builds explicitly:

python -m pip install --pre "pygraphdb[fast-ingest]"
