Both YOLOv3 PyTorch and YOLOv4 PyTorch are commonly used in computer vision projects. Below, we compare and contrast YOLOv3 PyTorch and YOLOv4 PyTorch.
Models
YOLOv3 PyTorch
Though it is no longer the most accurate object detection algorithm, YOLO v3 is still a very good choice when you need real-time detection while maintaining excellent accuracy. PyTorch version.
YOLOv4 has emerged as the best real time object detection model. YOLOv4 carries forward many of the research contributions of the YOLO family of models along with new modeling and data augmentation techniques. This implementation is in PyTorch.
