本文记录了使用PyInstaller将Python项目打包成exe过程中遇到的Mediapipe运行错误。问题在于打包后运行exe时找不到所需资源文件。通过分析源代码和添加缺失资源解决了问题。解决方案包括：查看错误信息、打印路径确认问题、使用pyinstaller的--add-data选项添加资源文件。
这篇文章主要是记录一下流水账。
背景
IDE使用的是Pycharm。Anaconda3安装的Python版本是3.8，在此基础上通过Pycharm安装了Opencv4.5.2.32和Mediapipe0.8.4.2.
在Pycharm的环境运行python是正常的，但是使用pyinstaller打包成exe，再运行就有问题了。打包过程:
