spyder中的内核重新启动（Ctrl +。）不起作用

【问题标题】：Kernel Restart (Ctrl+.) in spyder not workingspyder中的内核重新启动（Ctrl +。）不起作用
【发布时间】：2021-02-02 17:16:07
【问题描述】：

我最近更新了我的 Anaconda 和 Spyder 应用程序！但是在这个新版本的 Spyder（版本 4）中，当我重新启动内核（使用快捷键并从上面功能区中的控制台）时，会出现重新启动内核确认窗口，然后我按下“是”按钮但没有任何反应。 谁能帮我解决这个问题？

【问题讨论】：

  • (这里是 Spyder 维护者) 请务必更新到我们的最新版本 (4.1.5)。该版本有很多关于内核重启的修复。
  • @CarlosCordoba 感谢您的评论。我已经在用（4.1.5）版本了，但是问题依旧存在。
  • 您是否将 Spyder 连接到外部内核？我的意思是在 Spyder 之外创建的内核？
  • @CarlosCordoba 不，我没有更改首选项中的默认设置。但我注意到在运行任何代码之前，重新启动效果很好。但运行任何代码后，它停止工作！

【解决方案1】：

我对 Spyder 5.2.2 也有同样的问题：

  • Spyder 版本：5.2.2 无
  • Python 版本：3.7.9 64 位
  • Qt 版本：5.12.10
  • PyQt5 版本：5.12.3
  • 操作系统：Windows 10

重新启动内核时，我得到这个：

Python 3.7.9 (tags/v3.7.9:13c94747c7, Aug 17 2020, 18:58:18) [MSC v.1900 64 bit (AMD64)]
Type "copyright", "credits" or "license" for more information.

IPython 7.31.1 -- An enhanced Interactive Python.
