White Lines on Jupyter Notebook stopping kernal from running cells - jupyter-notebook

I'm working on a jupyter notebook at the minute and these 4 white lines have popped up which seems to kill the kernal. Manually I can run any cells after this but it won't do it automatically.

I can't click into them to edit or delete them. I have no idea where they appeared from.
Hoping someone can shed some light

I just Googled this as I have the same problem. Saving the Notebook and refreshing the browser window worked for me on a case-by-case basis.
But apparently it's fixed now, so updating your Jupyter-Lab should solve the issue.

Jupyter notebook opens slowly and extensions don't show up - [MathJax] issue

I'm trying to open a jupyter notebook and it takes a long time and I see at the bottom it's trying to load various [MathJax] extension, e.g. at the bottom left of the safari browser it says:
Loading [MathJax]/extensions/safe.js
Eventually, the notebook loads, but the extensions I used to have, don't show up (like table of contents and others)
I tried to run nbstripout with the relevant filename but it didn't change anything.
I also tried to reinstall jupyter.
I'm having the same issue with timing (but my extensions all seem to work OK). After a lot of experiments with MathJax options in the Jupyter configuration file it seems to be... not related to MathJax.
My guess is that's the last notice displayed, and it stays there while the rest of the notebook loads.
In my experiments, the time to load is directly related to the number of cells in the notebook.

Jupyter Notebook doing funky stuff when opening

I've just opened Jupyter Notebook like I always do, and it began doing some strange stuff, it's impossible to use. I've put up a 40-second video showing what's going on: https://youtu.be/8yDMT82Cju8
Basically upon creating a new notebook, the first cell appears really big (like if someone just pressed enter many times), and then it begins jumping further down. Any action, like typing, clicking, just adds more "lines" to the cell. Some weird xxxxxxxxxx characters show up and disappear randomly. All in all, it's unusable. No, there's no key stuck anywhere in case you thought about that. I've restarted the PC many times as well, to no success.
Funny thing is that this was working just yesterday and no software/hardware was modified in between.
I´ve just finished re-installing Anaconda and the problem has gone.
I'm gonna leave this here in case someone comes across the same issue.

Disappearance of all cell outputs of a jupyter notebook in Google Colab

I have a big problem. All cell outputs my Jupyter notebook in Google Colab are deleted. I do not know why, if I accidentally pressed "Restart and run all" or something similar.
Is there any way to restore the state of the notebook from this disappearance of the cell outputs?
Can someone help me? Many thanks for any help
Check the revision history using the File -> Revision history menu.
Slightly old, but adding an answer here anyway. If it doesn't appear in the revision history there you can refresh the page at which the notebooks are present, and the output should reappear even if you had previously cleared it.

Atom: Unstaged Changes Pop Up

I'm using the Atom IDE, and an "Unstaged Changes" tab pops up each time I switch to an other tab (see image below).
I know what unstaged changes are, I just don't know how to keep the window from popping up all the time. I've turned off all the packages that contain the word "git", but that didn't solve the isse. Any help would be appreciated!
Atom Unstaged Changes Tab
I uninstalled Atom, and reinstalled it. That solved the problem. I was hoping to not have to uninstall, but it was really making me crazy to work with the constant pop-ups.
Thanks for all the comments! It seems like it wasn't a problem with the .git file in the project folder (since that wouldn't be effected by reinstalling Atom)

mouse selection lost by status update in byobu/tmux

I'm on Mac 10.7.5 iTerm2, ssh'ing into an Ubuntu machine running byobu 5.12 with tmux 1.7.
The problem is that if I try to select text from the terminal with a mouse, it's gets cleared every time the time gets updated on the bottom right hand side of the status bar. That is, I select fine, then the clock ticks over, and it's cleared again.
Any workaround for this?
I just proposed this tiny fix http://bazaar.launchpad.net/~zekus-one/byobu/trunk/revision/1992 and is waiting for revision. That fixes the issue for me.
You should be able to edit /usr/bin/byobu-status and apply the fix manually while waiting for the official release.
Hope this helps.
