Details

The Core Deep Learning Engine subsystem in DeepLabCut is designed to abstract the complexities of underlying deep learning frameworks (TensorFlow/PyTorch) while providing robust capabilities for neural network model definition, training, inference (pose prediction), and internal evaluation. This modular design adheres to the project's emphasis on decoupling high-level application flow from specific deep learning implementations.

Framework Compatibility Layer

This component acts as a crucial abstraction layer, offering a unified interface for the rest of the DeepLabCut application to interact seamlessly with either the TensorFlow or PyTorch deep learning backends. It encapsulates framework-specific calls, allowing for flexible switching between implementations without altering higher-level logic.
