This is the TensorFlow Model Garden, a large monorepo of model implementations, training loops, and research code. The dominant character is an application/framework: it provides official TF2 model code under `official/`, a custom training library under `orbit/`, and a large body of research code under `research/` and `community/`. The codebase is not a single deployable service but a collection of training/eval/export scripts, model factories, config systems, and data pipelines. It uses Gin configs, dataclass-based configs, and a registry pattern to compose models, tasks, and data loaders. Tests exist across the repo, and CI workflows are present. The repository is hybrid in that it contains research-oriented experiments and data-processing code, but the core is a software framework for building and training TensorFlow models.
