如何解决"NotImplementedError"问题尝试在Atom中运行氢气时 [英] How to fix "NotImplementedError" when trying to run Hydrogen in Atom

问题描述

我试图在Atom上运行Hydrogen，但是在异步python lib中，我收到一条错误消息，该错误消息以"NotImplementedError"结尾.

I am trying to run Hydrogen on Atom, but I am getting an error message that ends with "NotImplementedError" in the asyncio python lib.

我在Windows 10机器上安装了Python3，并且我在jupyter上安装了ipython内核.

I have Python3 installed on a Windows 10 machine, and I have the ipython kernel installed with jupyter.

我收到以下错误消息，并且不确定从哪里开始解决问题.

I am getting the following error message, and I am not sure where to start to fix the problem.

推荐答案

异常来自龙卷风调用asyncio事件循环方法

The exception comes from Tornado invoking the asyncio event loop method add_reader which is not supported on Windows.

Tornado文档声明了有关平台的以下内容:

The Tornado documentation states the following about platforms:

平台: Tornado应该可以在任何类似Unix的平台上运行，尽管为了获得最佳性能和可伸缩性，建议仅将Linux(带有epoll)和BSD(带有kqueue)用于生产部署(即使Mac OS X衍生自BSD并支持kqueue，其网络性能通常也很差，因此建议仅用于开发用途). Tornado也将在Windows上运行，尽管此配置不受官方支持，建议仅用于开发.如果不重新设计Tornado IOLoop界面，就无法添加本地Tornado Windows IOLoop实现，也无法利用AsyncIO或Twisted等框架对Windows IOCP的支持.

Platforms: Tornado should run on any Unix-like platform, although for the best performance and scalability only Linux (with epoll) and BSD (with kqueue) are recommended for production deployment (even though Mac OS X is derived from BSD and supports kqueue, its networking performance is generally poor so it is recommended only for development use). Tornado will also run on Windows, although this configuration is not officially supported and is recommended only for development use. Without reworking Tornado IOLoop interface, it’s not possible to add a native Tornado Windows IOLoop implementation or leverage Windows’ IOCP support from frameworks like AsyncIO or Twisted.

最后一句话意味着Tornado的asyncio部分在Windows上尚不可用.

The last sentence means that the asyncio part of Tornado does not yet work on Windows.
