# Wheel metadata for tpu_raiden. The Bazel `py_wheel` rule in
# //ci/wheel:raiden_wheel reads [project].version from here (via
# //bazel:wheel_version.bzl) and appends WHEEL_VERSION_EXTRAS (e.g.
# ".dev<timestamp>") at build time. There is no setuptools build-system: the
# wheel is built by Bazel, not pip.

# Runtime dependencies that live on a public index. NOTE: the torch path also
# requires `torch_tpu`, which is published only to a private Artifact Registry
# and is therefore NOT declared here — it is a documented prerequisite for the
# torch extensions and must match the torch_tpu build raiden was compiled
# against (jax/jaxlib/libtpu are version-coupled too; keep them in lockstep).
