Google Cloud TPU Runtime Library

The `libtpu` library is a low-level runtime component that provides the interface for Python-based machine learning frameworks (such as JAX and PyTorch/XLA) to communicate with Google Cloud TPUs. It is primarily a dependency managed by these high-level frameworks rather than a library intended for direct user application development. The current version is 0.0.39 and it requires Python >= 3.11. It has no strict release cadence, with updates typically coinciding with changes in underlying TPU infrastructure or integrations with ML frameworks.
