YOLO (v7 and v5) both are state of art object detection algorithms. Both (YOLOv5 and YOLOv7) have been written in the PyTorch framework, while the latest among them is YOLOv7. Both are good, but each has its own limitations and drawbacks. I have received many messages on LinkedIn from people about the issues they are facing with using YOLOv5 and YOLOv7. In this article, I will answer the most frequent questions that I received, which can help you to understand and decide which algorithm is best according to your use case, and also why it's a challenge for people to decide which YOLO (v7 or v5) is better to be used in their products.
