  # How to resolve GitHub Actions ARM64 build timeout.
  #
  # When there are large amount of code change (e.g. changed some headers that
  # causes re-compilation of many files), the GitHub Actions build could timeout
  # due to excessive ccache misses. The solution is to build the branch manually
  # and update the ccache artifacts on the Google Cloud bucket. Run:
  #
  # ```bash
  # docker/docker_build.sh openblas-arm64-py36-dev
  # gsutil cp open3d-ci-openblas-arm64.tar.gz gs://open3d-ci-cache/
  # ```
