图像标注工具labelImg安装方法（win10+anaconda3+spyder（python3.7））
本机环境：win10+anaconda3+spyder（python3.7），注意安装的PyQt5、PyQt5_tools、lxml的版本要和安装的spyder的版本要匹配，否则会导致不兼容的问题，使安装有问题或者导致spyder无法启动。
下载LabelImg安装包，（下载地址为https://github.com/tzutalin/labelImg ）
（1）进入anaconda prompt或者cmd后，输入： pip install PyQt5 （本机匹配的pyqt5为小于5.13的版本，本机经过反复的安装和卸载输入指令为：pip install pyqt5==5.10.1）
亲测发现白天安装一般不成功，夜半三更的时候安装成功率比较高，这条指令一般会安装新版本的PyQt5 ，需要查询匹配版本。
尽管安装的匹配版本但是也会存在spyder无法启动的问题，所以要安装低版本的pyqt5，因此需要卸载。
（2）卸载PyQt5的指令为：pip uninstall pyqt5
输入指令显示如下：
(base) C:\Users\lifengmin>pip uninstall pyqt5

Proceed (y/n)? y
Successfully uninstalled pyqt5-tools-5.12.3.1.5
如若从新安装，则输入安装指令，如pip install PyQt5-tools==5.x.x
（5）安装lxml
命令：pip install lxml， 如下：
(base) C:\Users\lifengmin>pip install lxml
Requirement already satisfied: lxml in d:\anaconda3\lib\site-packages (4.6.2)
（6）pyrcc编译资源文件
进入到labelImg解压后的文件，labelImg-master。
执行命令： pyrcc5 -o resources.py resources.qrc ，
启动labelImg指令：python3 labelImg.py，但首先需要将路径改到下载的labelImg解压缩包，如下：
(base) C:\Users\lifengmin>cd D:\labelImg-master
(base) C:\Users\lifengmin>d:
(base) D:\labelImg-master>pyrcc5 -o resources.py resources.qrc
(base) D:\labelImg-master>python3 labelImg.py
（7）虽然打开代码还是有很多告警，但是，正常运行，没有问题。
注意：
（1）如果出现：“Consider using the `--user` option or check the permissions”的报错。
由指令pip uninstall pyqt5
改为指令pip install pyqt5==1.7 --user，就可安装。
（2）安装的时候报错ModuleNotFoundError: No module named ‘libs.resources’，查阅相关资料之后发现解决方案如下：
将LabelImg-master中的resources.py复制到libs文件中即可。
再输入命令python labelImg.py即可打开LabelImg。
（3）测试 pyqt5是否安装成功的办法：
代码如下：运行，如果出现对话框即完成。
import sys
from PyQt5.QtWidgets import QWidget, QApplication
if __name__ == '__main__':
app = QApplication(sys.argv)
w = QWidget()
w.show()
w.setWindowTitle("Hello PyQt5")
sys.exit(app.exec_()) 运行的结果：（成功了，好棒！）
（4）在安装过程中，也出现了spyder无法启动，anaconda服务崩溃的情况，也曾焦虑，也曾彷徨，但是经过在网上查找解决方法，也尝试了什么镜像安装也失败了，终于经过一晚上的安装，卸载，安装和卸载，也是可以运行了，总结了以安装步骤。主要原因就是版本不匹配，注意查看自己的spyder版本，不要以为追求高版本新版本哦。
