YOLOv8-PyQT5可视化界面

使用PyQT5实现YOLOv8图形化界面
准备工作：
1、首先在YOLOv8环境中安装pyqt5

pip install pyqt5
pip install pyqt5-tools

然后再你的anaconda环境中找到designer.exe文件，双击运行，可以将其发送到桌面快捷方式方便后续使用
下面是我的文件所在路径地址，根据自己环境的位置进行查找。
C:\User\anaconda\envs\yolov8\Lib\site-packages\qt5_applications\Qt\bin\designer.exe

2、运行的designer.exe后创建一个界面

如下图：

然后再右边任务栏中选择需要的功能

制作完界面之后将其保存到你的YOLOv8工程下，方便后续使用
我保存在如下位置

然后将使用pycharm扩展工具进行代码生成
步骤如下
点击File->Setting->External Tools->+(add)

程序去conda的envs我的环境路径如下所示，根据自己的环境位置进行寻找
C:\Users\Administrator\anaconda3\envs\yolov8\Scripts\pyuic5.exe
实参为：UI\$FileName$ -o UI\$FileNameWithoutExtension$.py
最后的工作目录可以写：
$ProjectFileDir$
保存成功后进行如下操作生成代码

这样界面就生成啦
然后再根据自己打需求编写代码
我的界面如下图所示

我自己的代码如下所示
