name: CI - with Numpy/Scipy nightly wheels (nightly)
# This configures a github action that runs the JAX test suite against nightly development builds
# of numpy and scipy, in order to catch issues with new package versions prior to their release.
# Unlike our other CI, this is one that we expect to fail frequently, and so we don't run it against
# every commit and PR in the repository. Rather, we run it on a schedule, and failures lead to an
# issue being created or updated.
# Portions of this adapted from https://github.com/pydata/xarray/blob/main/.github/workflows/upstream-dev-ci.yaml
