The packaging process mainly refers to PyInstaller packaging details
Multithreading bug
No error is reported during the build process. After running the exe, an empty command line window pops up, and the task manager is called up to find that main.exe is constantly starting the process.
After you have reviewed pyinstaller document discovery may open the debug mode, the main.specfile is modified debug=True,and re
pyinstaller main.spec
Generate an executable file in debug mode, double-click to run main.exe and print out the command line, you can see that the program is exhausted and call mine repeatedly main.py.

Refer to the description in the official pyinstaller documentation.
When using multi-threaded modules multiprocessing, you must add code to the program entry
if __name__ == '__main__':
# Pyinstaller fix
multiprocessing.freeze_support()
# 以下写主要代码
main()
After this change, you can package and run the exe.
