Build helper code for LensKit packages.

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.
