Yolov5 improvements: replace the backbone

Course link ：https://download.csdn.net/course/detail/37465

PyTorch Version of YOLOv5 It is a very popular target detector at present , This course is about YOLOv5 Replace the backbone network （backbone） Methods , Make it lighter or improve performance .

This course is in YOLOv5 v6.1 Replace its backbone network based on the version code , stay Windows and Ubuntu The system demonstrates the replacement of the backbone network for its own data set 、 Focus on the training and performance evaluation process , And explain the principle of the backbone network model and the modified part of the original code for backbone network replacement .

The following backbone networks have been used and replaced in the course ：YOLOv5s、YOLOv5n、MobileNetV2、MobileNetV3、 ShuffleNetV2、GhostNet、Transformer

The actual combat process of the project includes ：PyTorch Environmental installation 、YOLOv5 Project installation 、 Prepare your own dataset 、 Modify the configuration file 、 Training network model and performance evaluation .
