“main thread is not in main loop”这个错误信息通常出现在多线程或多进程编程环境中,特别是在图形用户界面(GUI)框架中较为常见。它意味着主线程(通常负责处理GUI事件循环的线程)不在其预期的事件循环中执行,或者由于某种原因,主线程被阻塞或错误地调度到了其他任务上,导致GUI无法正常响应或更新。 列举可能导致该...
方法一(Tkinter) 最后写 代码语言:javascript 复制 root.mainloop() 当然,如果不是root,则应使用Tk对象的名称代替root。 方法二(多线程) 将线程设置为守护程序 代码语言:javascript 复制 t=threading.Thread(target=your_func)t.setDaemon(True)t.start() daemon默认是False,将其设置为True,再Start,就可以解决问题。
将线程设置为守护程序 t = threading.Thread(target=your_func)t.setDaemon(True)t.start() daemon默认是False,将其设置为True,再Start,就可以解决问题。daemon为True,就是我们平常理解的后台线程,用Ctrl-C关闭程序,所有后台线程都会被自动关闭。如果daemon属性是False,线程不会随主线程的结束而结束,这时如果线程访问...
例如,下面的示例代码演示了主线程被阻塞的情况: importtimedeflong_running_task():time.sleep(5)defmain():long_running_task()print("Main thread is not in main loop.")if__name__=="__main__":main() 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 在这个例子中,long_running_task函数模拟了...
RuntimeError: main thread is not in main loop 问题 使用pytorch跑网络报错 RuntimeError: main thread is not in main loop Tcl_AsyncDelete: async handler deleted by the wrong thread (报错内容:主线程不在主循环中,异步处理程序被错误的线程删除,其实就是多线程的问题)...
