在Python中遇到DeprecationWarning: There is no current event loop警告通常与异步编程中的事件循环管理有关。这个警告表明,代码试图在没有当前事件循环的上下文中执行异步操作。以下是对这个问题的详细分析和解决方法: 1. 确认问题出现的上下文 这个警告通常出现在以下几种情况: 在没有显式创建或设置事件循环的情况下尝...
lo = asyncio.new_event_loop() asyncio.set_event_loop(lo) # 将协程对象注册到循环对象中,启动loop #loop.run_until_complete(a) # task 的使用 task = lo.create_task(a) print(task) #将task注册到循环对象中,启动loop #loop.run_until_complete(task) # 可执行 print(task) # future 的使用 fut...
RuntimeError: There is no current event loop in thread 'Thread-1'. 这个问题: RuntimeError: There is no current event loop in thread in async + apscheduler 遇到了同样的问题,但是他们引用了我没有的调度程序。 我的代码如下: def worker(ws): l1 = asyncio.get_event_loop() l1.run_until_...
even if the current loop was set on the policy. In Python versions 3.10.9, 3.11.1 and 3.12 they emit aDeprecationWarningif there is no running event loop and no current loop is set. In some future
这个问题:RuntimeError: There is no current event loop in thread in async + apscheduler遇到了同样的问题,但是他们引用了我没有的调度程序。 我的代码如下: def worker(ws): l1 = asyncio.get_event_loop() l1.run_until_complete(ws.start()) ...
RuntimeError: There is no current event loop in thread 'Thread-2'. The cause of the error I am encountering while running the flask app is uncertain. Although, the test programs are functioning flawlessly with reading and writing operations, however, when these functions are imported...
首先,你得到的AssertionError: There is no current event loop in thread ‘Thread-1’.是因为asyncio程序中的每个线程都有自己的事件循环,但它只会在主线程中为你自动创建一个事件循环。所以如果你asyncio.get_event_loop在主线程中调用一次,它将自动创建一个循环对象并将其设置为默认值,但是如果你在一个子线程...
Hi, 233a818 in release 3.0.37 re-introduces asyncio.get_event_loop() which was deprecated and removed in a775996 earlier in the same release. My Python 3.10 venv fails with prompt-toolkit==3.0.38, but a similar Python 3.8 venv is ok. Dow...
If there is no current event loop set in the current OS thread, the OS thread is main, andset_event_loop()has not yet been called, asyncio will create a new event loop and set it as the current one. Because this function has rather complex behavior (especially when custom event loop ...
任务实现了Runnable接口 )。 当任务完成，线程返回给队列，并可用
