| # Cloud TPU CI | |
| # | |
| # This job currently runs once per day. We use self-hosted TPU runners, so we'd | |
| # have to add more runners to run on every commit. | |
| # | |
| # This job's build matrix runs over several TPU architectures using both the | |
| # latest released jaxlib on PyPi ("pypi_latest") and the latest nightly | |
| # jaxlib.("nightly"). It also installs a matching libtpu, either the one pinned | |
| # to the release for "pypi_latest", or the latest nightly.for "nightly". It | |
| # always locally installs jax from github head (already checked out by the | |
| # Github Actions environment). | |
