是否可以在Jupyter笔记本中运行pypy内核？（jupyter可以运行.py文件吗）
我一直想知道是否有可能在Jupyter笔记本中运行PyPy。我最近尝试在本地计算机上安装PyPy，并且运行得非常好-
使用纯Python编写的基于代理的仿真速度提高了100倍。但是，我错过了Jupyter笔记本中的交互性。是否可以使IPython内核使用PyPy而不是CPython？
答案1
小编典典如果您具有的系统范围/用户安装jupyter。您可以遵循：
pypy3 -m venv PyPy3source PyPy3/bin/activatepypy3 -m pip install ipykernelipython kernel install --user --name=PyPy3现在退出虚拟环境并验证安装：
jupyter kernelspec list打开Jupyter笔记本或实验室界面。
Anaconda Jupyter笔记本中的内核错误
如何解决Anaconda Jupyter笔记本中的内核错误？
我在Windows 10的Anaconda中安装了新版本的anaconda。我在Jupyter笔记本中收到内核错误。我尝试了多种方法来修复它。失败。这是错误。有人可以指导吗？谢谢

Jupyter笔记本中的方程式编号
事实是，在官方文档Jupyter -激励例子看台
方程式编号和引用将在Jupyter笔记本的将来版本中提供。
我知道有关此主题的讨论很多。有些人声称可以通过一些解决方法来解决此问题。
但是，对于普通用户而言，很难理解变通方法或这些hack到底有多脏/没用。
所以我的问题是：
-
什么是“将来版本可用”？它是指诸如“新月/年”之类的事物，还是诸如“可能永远不会因为它太不可能”之类的事物？
-
Internet上提供的任何变通方法是否对人类食用安全？我的意思是值得吗？因为可以使用Sphinx或其他方法来创建教程，所以要做更多的工作，但是实施一些技巧，安装插件等等将是更多的工作？
注意：对于某些人来说，这似乎是一个需要基于意见的答案的问题，但我敢肯定它不是。任何建议都可以帮助我（或其他用户）做出好/坏决定。
Jupyter笔记本内核或路径混乱
如何解决Jupyter笔记本内核或路径混乱？
我正在将jupyter笔记本与anaconda安装的python3.7一起使用。如果我打开anaconda应用程序，请选择基本环境，然后单击Open with Jupyter Notebook，它可以正常运行。
如果我从Windows命令行键入jupyter notebook，则会收到以下消息：
Traceback (most recent call last):
File "C:\Users\z5044992\AppData\Local\Continuum\anaconda3\Scripts\jupyter-notebook-script.py",line 6,in <module>

import _ssl # if we can''t import it,let the error propagate
ImportError: DLL load Failed: The specified module Could not be found.
我认为这可能是路径问题。
在jupyter笔记本（通过Anaconda运行）中的 sys.path给出：
''C:\\Users\\z5044992\\AppData\\Local\\Continuum\\anaconda3\\python37.zip'',''C:\\Users\\z5044992\\AppData\\Local\\Continuum\\anaconda3\\DLLs'',''C:\\Users\\z5044992\\AppData\\Local\\Continuum\\anaconda3\\lib'',''C:\\Users\\z5044992\\AppData\\Local\\Continuum\\anaconda3'','''',''C:\\Users\\z5044992\\AppData\\Roaming\\Python\\python37\\site-packages'',''C:\\Users\\z5044992\\AppData\\Roaming\\Python\\python37\\site-packages\\win32'',''C:\\Users\\z5044992\\AppData\\Roaming\\Python\\python37\\site-packages\\win32\\lib'',''C:\\Users\\z5044992\\AppData\\Roaming\\Python\\python37\\site-packages\\Pythonwin'',''C:\\Users\\z5044992\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages'',''C:\\Users\\z5044992\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\win32'',''C:\\Users\\z5044992\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\win32\\lib'',''C:\\Users\\z5044992\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\Pythonwin'',''C:\\Users\\z5044992\\AppData\\Roaming\\Python\\python37\\site-packages\\IPython\\extensions'',''C:\\Users\\z5044992\\.ipython''
在环境变量中，我有一个名为PATH的用户变量，其中包括：
C:\Users\z5044992\AppData\Local\Continuum\anaconda3
C:\Users\z5044992
C:\Users\z5044992\AppData\Local\Continuum\anaconda3\Scripts
C:\Users\z5044992\AppData\Roaming\Python\python37\site-packages\
和一个名为PATH的系统变量，其中包括：

C:\Users\z5044992\AppData\Local\Continuum\anaconda3\pkgs

我想念什么吗？

Jupyter笔记本内核未连接
我以前Jupyter Notebook在Mac上使用过（python
2和3）。一段时间不使用后，似乎无法解决问题。使用命令从终端启动笔记本时Jupyter notebook，然后选择我要使用的笔记本，出现错误：
"A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration."
我肯定这与我的Internet连接无关（我尝试了2台连接到不同网络的机器）。
我已经读过浏览器可能是问题所在，因此我已经安装了Chrome和Firefox。但是，当我使用Safari，Chrome和Firefox时出现此错误。
然后我读到它是代理问题。我试图将笔记本的服务器地址添加到No proxy fieldsMac的高级网络首选项和Firefox的高级设置中。
我唯一能想到的是我输入了错误的服务器地址？
我一般对设置和错误了解不多，希望有人可以为我提供一些替代选择，以使Jupyter再次工作。
终端输出：
