PyQt4, QThread requests executed stuck in no reaction, even set the timeout-CodePudding

1. The whole process:
UI click on executive function, "start QThread -" execution requests. The get - "pyqtSignal echo signal and data to the UI slot function -" processing

2. Problem description:
No problem when I run in the pycharm,
Use pyinstaller run after packaging, the execution requests. When the get stuck, set the timeout didn't also timeout error,
Does not use in the QThread requests is no problem, can use normally requests,

3. Q:
What specific reasons? How to solve?
Guess packaging issues, but the UI is developed using PyQt, can normal boot, QThread also can start, but no response to perform to requests,
