Python继续运行pyter无法重新连接的代码

Question

我搜索过其他帖子，似乎找不到一个能满足我对jupyter笔记本问题的答案。笔记本电脑启动良好，但不断重新连接内核，不会执行任何代码块。我只在左边的括号里有一个星，它甚至不会执行一个简单的print语句。以下是jupyter笔记本客户端的输出：

我看到上面写着“终端不可用”，但不确定如何解决这个问题。我目前正在学习Python视频课程，并建议使用jupyter笔记本。所以我不知道如何解决这个问题。谢谢你的帮助！我正在运行Win10 64位。在

编辑：根本不要求密码，是的，我第一次使用令牌登录。一切启动良好，并创建新的Python3笔记本文件。但一旦进入笔记本，它就不会运行任何代码行。我按了shift+enter来执行单元格，它只带我到下一个空白单元格，而不执行任何操作。在

Answer 1

试着降低你的龙卷风版本。当conda将Tornado升级到6.0时，我也遇到了类似的问题：单元无法执行。在

$ conda install tornado=5.1.1

conda回购中还没有Tornado 5.7.5。在

Answer 2

如果jupyter设置在反向代理（nginx）之后，请参阅这里的答案。 这对我有用：jupyter notebook keeps reconnecting

Answer 3

我也有类似的问题。进入Anaconda>；环境并在那里更新ipython和ipkernel模块似乎解决了这个问题。在
