在Python中遇到“RuntimeError: There is no current event loop in thread 'ThreadPoolExecutor'”错误通常是因为尝试在非主线程中运行异步代码,但该线程没有自己的事件循环。 原因分析 在Python的asyncio模块中,事件循环(event loop)是线程局部的。主线程默认有一个事件循环,但子线程(如ThreadPoolExecutor创建的线程...
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()) l2 = asyncio.get_event_loop() l2.run_forever() if...
DeprecationWarning: There is no current event loop 这里就是你的错误了我的是:lo = asyncio.get_event_loop() || future = asyncio.ensure_future(a) 里面的参数不用多看,格式几乎都是一样的 解决方法: 我也是查阅了许多古籍,比如《春秋》,《战国》,很失望没找到,不过我并不气馁,终于在看完最强大脑后,我...

Get the current event loop.If there is no current event loop set in the current OS thread, the OS thread is main, and set_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 (espec...
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...
