LensKit build support code

This repository provides support code for use in LensKit builds and development. If you are trying to use LensKit, you don't need it; it is only used for working on developing LensKit (and related packages).

To set up a Conda environment that contains the utilities needed to bootstrap a LensKit development environment:

conda env create -n lkboot -f https://raw.githubusercontent.com/lenskit/lkbuild/main/boot-env.yml

Then you can run the lkbuild utilities:

conda activate lkboot
lkbuild --help

For example, you can create a lock file for developing LensKit:

lkbuild dev-lock -v 3.9 -b mkl

Or you can download some testing data:

lkbuild fetch-data -d ml-20m

You can also install into a Python environment with one of:

pip install lenskit-build-helpers
conda install -c lenskit lenskit-build-helpers

GitHub Actions

This repository also provides some GitHub actions to support our CI workflow.

• actions/setup-env — sets up an Anaconda environment based on locking the dependencies from pyproject.toml.
