yolov3 and yolov3-tf2
These are **competitors** offering alternative implementations of the same YOLOv3 algorithm—one optimized for PyTorch with multi-framework export capabilities, the other built natively in TensorFlow 2.0—so users typically choose based on their preferred deep learning framework rather than using both together.
About yolov3
ultralytics/yolov3
YOLOv3 in PyTorch > ONNX > CoreML > TFLite
Implements multi-scale feature pyramids and anchor-based detection with spatial attention mechanisms for improved accuracy on small objects. Provides built-in training pipelines with data augmentation, mixed-precision support, and batch normalization optimization across PyTorch, ONNX, CoreML, and TFLite export targets for seamless deployment across cloud and edge devices.
