A PyTorch implementation of the YOLOv4 real-time object detection model, based on ultralytics/yolov3. It includes research extensions such as instance segmentation, transformer backbones, and various loss functions.

Use cases

• train a custom object detection model in pytorch
• run real-time object detection on images and video
• implement yolov4 without darknet
• add instance segmentation to yolo detection
• experiment with transformer backbones for detection

When to choose

• you want a PyTorch-native YOLOv4 with research extensions like segmentation and attention modules
• you need to train or fine-tune YOLO models on custom datasets

When to avoid

• you need a maintained production detector with active support and a clear license
• you want the latest YOLO versions or simple out-of-the-box inference APIs
