在IPython Notebook的Python 3内核中未生成任何输出单元格

[英]No output cells generated in Python 3 Kernel of IPython Notebook

I've tried to install both python2 and python3 kernels as suggested here and here (through pip and pip3 ipykernel install ), but in all the variants I end up with working python2 kernel and almost-working python3 one. 我尝试按照此处和此处的建议（通过pip和pip3 ipykernel install ）安装python2和python3内核，但是在所有变体中，我最终都可以使用python2内核，并且几乎可以使用python3 。

python3 kernel is displayed as the option in "New" dropdown menu, but all notebooks created under it don't produce any output. python3内核在“新建”（New）下拉菜单中显示为选项，但是在该内核下创建的所有笔记本均不产生任何输出。

That is, I can create new cell, paste print(5) in there and run it (the runcount to the left will be incremented), but no output cell is produced. 也就是说，我可以创建新的单元格，在其中粘贴print(5)并运行它（左侧的运行计数将增加），但是不会生成任何输出单元格。

Same (no) reaction is observed on syntactically-wrong code. 在语法错误的代码上观察到相同（否）的反应。

Any ideas on where to go? 有什么想法去哪里？

Ok, nevermind, looks like some deeeeep interdependence-out-of-date bug on this specific machine. 好的，没关系，看起来像是这台特定机器上的一些深层的相互依存错误。 After one more from-scratch setup it works. 从头开始进行另一次设置后，它可以工作。 Thank you, Thomas, for assistance! 谢谢托马斯的帮助！
