这是因为在IPython里面支持方便的使用await执行协程,但如果直接用 asyncio.create_task会报「no running event loop」: Eventloop是在单进程里面的单线程中的,在IPython里面await的时候会把协程注册到一个线程的Eventloop上,但是REPL环境是另外一个线程,不是一个线程,所以会提示这个错误,
I am testing with python 3.12.3 and PySide6 6.7.0. When using qasync >= 0.24.2, the attached script fails on the call to asyncio.create_task with this exception: Traceback (most recent call last): File "/Users/jdp/python/./qtest.py", lin...

import asyncio try: loop = asyncio.get_running_loop() except RuntimeError: print("No loop running") 在Python 3.7 中,有两种有效的方法来获取当前正在运行的循环实例。我们可以调用 asyncio.get_event_loop 或 asyncio.get_running_loop但asyncio.get_event_loop 内部是做了什么?大概下面几点1.检查在调用...
asyncio.get_running_loop() # 报错信息如下 # RuntimeError: no running event loop (2) loop=asyncio.get_event_loop() 获得一个事件循环,如果当前线程没有事件循环则创建一个新的事件循环,等同于asyncio.new_event_loop() 举例经常用到,暂无示例 ...

Consider also using the asyncio.run() function instead of using lower level functions to manually create and close an event loop.Deprecated since version 3.10: Deprecation warning is emitted if there is no running event loop. In future Python releases, this function will be an alias of get_...
