Custom Model Architecture Implementation Via Modular Building Blocks

via “custom model architecture composition via modular components”

Meta's modular object detection platform on PyTorch.

Unique: Registry-based component system that enables custom architectures to be defined as nn.Module subclasses and composed via config, without modifying core Detectron2 code or forking the repository

vs others: More extensible than monolithic frameworks because components are registered and instantiated dynamically, enabling custom architectures to coexist with built-in ones in the same codebase
