Python Jupyter Notebook无法运行代码-不断重新连接

Question

我搜索了其他帖子，但似乎找不到满足我的Jupyter Notebook问题的答案。笔记本可以正常启动，但会继续重新连接内核，并且不会执行任何代码块。我只是在左边的括号中有一个星星，它甚至不执行简单的打印语句。这是从jupyter笔记本客户端输出的：

我看到它说“终端不可用”，但不确定如何解决。我目前正在通过视频课程学习Python，建议使用jupyter笔记本。因此，我没有背景知道如何解决此问题。谢谢您的帮助！我正在运行Win10 64位。

编辑：根本不要求输入密码，是的，我第一次使用令牌登录。一切正常，并创建了新的Python3笔记本文件。但是一旦进入笔记本，它就不会运行任何代码行。我按下shift + enter来执行该单元格，它只是将我带到下一个空白单元格而没有执行任何操作。

Answer 1

我有一个类似的问题。进入Anaconda-> Environments并在那里更新ipython和ipkernel模块似乎为我解决了这个问题。

Answer 2

尝试降级您的Tornado版本。当conda将Tornado升级到6.0时，我遇到了类似的问题，即单元无法执行。

$ conda install tornado=5.1.1

Tornado 5.7.5尚未在conda仓库中提供。

Answer 3

如果在反向代理（nginx）后面设置了jupyter，请参考此处的答案。 这对我有用：jupyter notebook keeps reconnecting
