背景：学习关于深度学习的内容，发现网上LabelImg的内容，没有有Linux版本的，后来实践发现Linux下快速安装LabelImg_makefile:24: recipe for target 'qt5py3' failed ana-CSDN博客

于是就走上不归路。

1.切换conda环境，准备一个目录，包含图像文件夹，标注文件夹，标注说明文件

2.在这个项目文件夹内，git clone https://github.com/Ruolingdeng/labelImg.git，后面果断放弃在前面这里下载，https://github.com/HumanSignal/labelImg.git  在这里下载不会出现后面5的问题

3.下载工具 sudo apt-get install pyqt5-dev-tools \   conda install pyqt5==5.10  \ conda install lxml

4.安装完之后，在labelimg文件目录下，make qt5py3，然后python3 labelImg.py运行。

5.后面运行的时候发现报错

labelimg 打框就闪退 TypeError: setValue(self, int): argument 1 has unexpected type ‘float‘-CSDN博客这里有两种解法，这里用第二种解决。
