问题 Whenever I start jupyter notebook and create a new python 3 notebook I get an error message saying kernel has died. I have tried deleting and installing ipython, python3.6.5, and jupyter notebook but I still get the error message. My cmd screen is as follows:- [I 06:46:36.432 NotebookApp] KernelRestarter: restarting kernel (4/5), new random ports WARNING:root:kernel 0d0442a9-c92f-46e6-acdd-08ca0a18c5f2 restarted Traceback (most recent call last): File "c:\users\user\appdata\local\programs

问题 When I try to use iPython's auto-completion, the session crashes with the following error: Traceback (most recent call last): File "/usr/local/lib/python3.9/site-packages/IPython/terminal/ptutils.py", line 113, in get_completions yield from self._get_completions(body, offset, cursor_position, self.ipy_completer) File "/usr/local/lib/python3.9/site-packages/IPython/terminal/ptutils.py", line 129, in _get_completions for c in completions: File "/usr/local/lib/python3.9/site-packages/IPython

Python和Python解释器

[TOC] 一、Python介绍 Python的创始人为吉多·范罗苏姆（Guido van Rossum），如下图，少数几个不秃头的语言创始人。1989年的圣诞节期间，Guido为了打发圣诞节的无聊时光，开始写能够解释Python语言语法的解释器。Python这个名字，来自Guido所挚爱的电视剧Monty Python’s Flying Circus。他希望这个新的叫做Python的语言，能符合他的理想：创造一种C和shell之间，功能全面，易学易用，可拓展的语言。 最新的TIOBE排行榜，Python赶超PHP占据第4， Python崇尚优美、清晰、简单，是一个优秀并广泛使用的语言。 Python可以应用于众多领域，如：数据分析、组件集成、网络服务、图像处理、数值计算和科学计算等众多领域。目前业内几乎所有大中型互联网企业都在使用Python，如：Youtube、Dropbox、BT、Quora（中国知乎）、豆瓣、知乎、Google、Yahoo!、Facebook、NASA、百度、腾讯、汽车之家、美团等。 一定要注意的一点，我们说的Python，其实说的是Python解释器。 二、Python解释器发展史 Python刚问世的时候，大多数公司原有的软件是python2.+写的（这不废话吗？），由于开发软件是需要成本的，因此一些公司无法抛弃以前的代码，所以曾经在2008年推出3.

How to select current cell with JavaScript in Jupyter?

问题 I have a notebook cell containing JavaScript code, and I would like the code to select this particular cell. Unfortunately, the behavior of get_selected_cell depends on whether I execute the cell in place, or execute and select the cell below. Example: %%javascript var cell = Jupyter.notebook.get_selected_cell(); console.log(Jupyter.notebook.find_cell_index(cell)); When executing this cell, the console output will be different whether I execute with Ctrl+Enter or Shift+Enter . In one case it

IPython and Jupyter autocomplete not working

由 混江龙づ霸主 提交于 2021-01-21 00:45:42
问题 I am very new to this and I have no idea why the autocomplete is not working. I tried modifying the ipython config file, installed readline, but still nothing. Help! 回答1: A possible reason a user may believe that autocomplete is not working may be that autocomplete is just taking too long . Circa 2020-11-27 this is particularly true for Pandas when operating with jedi in a Jupiter notebook environment. The issue can be solved by using the following magic which deactivates jedi %config
