## user story fixes https://github.com/lancedb/lancedb/issues/1480 https://github.com/invl/retry has not had an update in 8 years, one if its sub-dependencies via requirements.txt (https://github.com/pytest-dev/py) is no longer maintained and has a high severity vulnerability (CVE-2022-42969). retry is only used for a single function in the python codebase for a deprecated helper function `with_embeddings`, which was created for an older tutorial (https://github.com/lancedb/lancedb/pull/12) [but is now deprecated](https://lancedb.github.io/lancedb/embeddings/legacy/). ## changes i backported a limited range of functionality of the `@retry()` decorator directly into lancedb so that we no longer have a dependency to the `retry` package. ## tests ``` /Users/james/src/lancedb/python $ ruff check .

LanceDB
A Python library for LanceDB.
Installation
pip install lancedb
Usage
Basic Example
import lancedb
db = lancedb.connect('<PATH_TO_LANCEDB_DATASET>')
table = db.open_table('my_table')
results = table.search([0.1, 0.3]).limit(20).to_list()
print(results)
Development
LanceDb is based on the rust crate lancedb and is built with maturin. In order to build with maturin
you will either need a conda environment or a virtual environment (venv).
python -m venv venv
. ./venv/bin/activate
Install the necessary packages:
python -m pip install .[tests,dev]
To build the python package you can use maturin:
# This will build the rust bindings and place them in the appropriate place
# in your venv or conda environment
maturin develop
To run the unit tests:
pytest
To run the doc tests:
pytest --doctest-modules python/lancedb
To run linter and automatically fix all errors:
ruff format python
ruff --fix python
If any packages are missing, install them with:
pip install <PACKAGE_NAME>
For Windows users, there may be errors when installing packages, so these commands may be helpful:
Activate the virtual environment:
. .\venv\Scripts\activate
You may need to run the installs separately:
pip install -e .[tests]
pip install -e .[dev]
tantivy requires rust to be installed, so install it with conda, as it doesn't support windows installation:
pip install wheel
pip install cargo
conda install rust
pip install tantivy
