loop.run_forever(): 在调用 stop() 之前将一直运行。
查阅资料后发现,发现使用jupyter notebook环境,其连接着 IPython 内核,而 IPython 内核本身在事件循环上运行,而 asyncio 不允许嵌套其事件循环,因此会出现如上图的错误信息。 nest_asyncio 作为异步操作的补丁而存在,具体内容请参考:
例子: importasyncioimportconcurrent.futuresdefblocking_io():# File operations (such as logging) can block the# event loop: run them in a thread pool.withopen('/dev/urandom','rb')asf:returnf.read(100)defcpu_bound():# CPU-bound operations will block the event loop:# in general it is p...
A define-by-run IR means the IR uses executable Python code to define the bodies of loops, giving TorchInductor's IR much of the power of full Python, removing the need for a large amount of boilerplate, and allowing lowerings to be written concisely. The key advantage of this IR is ...
raise RuntimeError('Eventloopisclosed') RuntimeError: Eventloopisclosed 原因分析 像aiohttp 这类第三方协程库都是依赖于标准库 asyncio 的,而 asyncio 对 Windows 的支持本来就不好。Python3.8 后默认 Windows 系统上的事件循环采用ProactorEventLoop(仅用于 Windows )这篇文档描述了其在 Windows 下的缺陷:https...
2. 错误消息:Event loop is closed 3. 解决方法 问题描述 首先,我们需要了解这个错误的发生原因。当我们在使用Python异步编程时,特别是使用asyncio库时,可能会遇到"RuntimeError: Event loop is closed"错误。这个错误通常在以下场景中发生: 在异步任务执行完毕后,再次调用asyncio.get_event_loop().run_until_compl...
为了解决RuntimeError: Event loop is closed错误,我们需要确保在使用asyncio.run()函数之前,事件循环是打开的。 有两种方法来处理这个问题: 方法一:使用异步上下文管理器 Python 3.7版本引入了一个新的语法,称为异步上下文管理器。它可以确保在进入上下文块之前打开事件循环,并在退出上下文块之后关闭事件循环。
