Yolo5V

Tensorflow

1. Install tensorflow, such as "sudo pip install tensorflow>=1.15 or tensorflow > 2.0" etc.

Introduction

A tensorflow implementation of YOLOv5 inspired by https://github.com/ultralytics/yolov5.

Neck: SPP[3], PAN[4];

Head: YOLOv5/YOLOv4(Mish), YOLOv3(Leaky_ReLU)[10];

Loss: DIOU CIOU[5], Focal_Loss[6]; Other: Label_Smoothing[7];

Environment

Python 3.6.8

Tensorflow 1.13.1 or Tensorflow 2.0 up

Quick Start

1. Download YOLOv5 weights from yolov5.weights.

2. Train Yolov5.

3. Run Yolov5.

Train

In core/config.py add your own path.

usage: python train.py gpu_id net_type(yolov5)

python train.py 0 yolov5

Usage

Inference

python test.py

python demo.py
