The cache is in ~/.cache/chromium/Default/Cache/ (I use chromium) used grep in binary search mode, grep -a ‘import math’ (replace search string by a keyword specific in your code) Edit the binary file in vim … Read more
In general, stackoverflow question should try to only ask one question at the time. That being said, I’ll try to answer the questions as best I can: ipywidgets is the main way, yes. It is what people mean when they talk about notebook widgets. There is an issue tracking general JS in jupyterlab on the … Read more
I’m finding local library names must begin with a capital letter. If I keep all my local files in a folder called Code, I can import them; if it’s called code, I cannot. (The names of subfolders and subfiles don’t seem to suffer that restriction.) This appears to be a Jupyter restriction, not a Python … Read more
I am taking @Taar’s comment and making it an actual answer since it worked for the original person who asked the question and for myself. from IPython.display import display, Javascript display(Javascript(‘IPython.notebook.save_checkpoint();’)) This will create checkpoints – same thing as CTRL-s. Note: in Jupyter, CTRL-s triggers an async process and the file save is actually completed … Read more

The Property Inspector comes built-in … Read more
Update: I checked all the methods, all of them are working. 1: Request password using getpass module which essentially hides input by user and then run sudo command in python. import getpass import os password = getpass.getpass() command = “sudo -S apt-get update” #can be any command but don’t forget -S as it enables input … Read more
There’s a Notebook gist by Fernando Perez here that demonstrates how to programmatically create new cells. Note that you can also pass metadata in, so if you’re generating a report and want to turn the notebook into a slideshow, you can easily indicate whether the cell should be a slide, sub-slide, fragment, etc. You can … Read more
After installing tcolorbox using LaTex’s package manager tlmgr, I was getting similar errors for other dependencies. The solution below worked for me on Ubuntu 18.04 (64 bit) at the terminal: tlmgr update –all –self tlmgr install tcolorbox tlmgr install pgf tlmgr install xcolor tlmgr install environ tlmgr install trimspaces tlmgr install mathpazo tlmgr install parskip … Read more
A more elegant solution would be: args, unknown = parser.parse_known_args() instead of args = parser.parse_args()
