 self.thread.setPath(self.img_url)
 self.thread.setWorker(self.worker)
 QThreadPool.globalInstance().start(self.thread)

I use print function, find the thread really start execute, but after several seconds, the program will exit without any message. Who can help me explain about this? Is it too complicated about the sub thread? :)

  sorry about the unclear edition, It will just output "start pre train". But when it go into worker.pretrain(), the program will exit(). (So, could it provide enough message about the issue?)

  @LuoNet Have you created an eventloop with QCoreApplication, QGuiApplication or QApplication ?, the cause of the error could be many so if you want help you should provide an Minimal, Complete, and Verifiable example
