NotJSONError('Notebook does not appear to be JSON: '# -- coding: utf-8 --\n"""\nSpyder Ed...')
Does anyone knows why this is happening?
I just click on the "open with" and then click on "open with Google Chrome". It went messy.
Normally my Jupyter notebooks opens fine with Microsoft Edge.

I am running some python code using a jupyter notebook. The notebook should take a couple of days to finish. After a couple of running hours a massage is shown: "Error rendering Jupyter widget: missing widget manager." The hourglass at the chrome tab keeps on running, but the * symbol next to the cell no longer appears, only [] is appeared. I have two questions: 1. is the notebook still running? 2. How can I fix this?
After closing jupyter lab and re-launching jupyter lab, it always opens a notebook that was shutdown in previous session. How do I properly remove that notebook from re-opening on every launch?
jupyter lab --version #1.2.15
any notebook created in Jupyter lab gets auto saved and by default it autoloads the previous session which was last worked upon. Even your untitled notebooks gets autosaved, you can always check in the path where it is installed
[right click the kernal and there ill be a delete option or use the close button (x) right on top]
I've lost a day's work in Jupyter Notebook because it didn't autosave. As I was working, I would click on File > Save and Checkpoint to be safe. I closed the notebook when I finished working and when I tried reopening it, I see that essentially all my work is gone and it says Last Checkpoint: a day ago (autosaved) next to the filename. I now realize that I had been working for a long time on the notebook with an orange box with some kind of error message. I'm sorry that I can't remember the specific message right now, but I think it was something involving POS or POST or POSIT ...?. I saw Trusted next to the error message, so I must've thought things were OK.
I tried opening the filename-checkpoint.ipynb file within the .ipynb_checkpoints folder but it's blank. I looked up a possible solution on Recovering from a Jupyter Disaster, but it requires SQL, which I don't know. Is there any hope for recovering my work? I realize that this is probably a rookie mistake, but I'm pretty new at this.
Thanks
PS: I'm running Python3 on MacOS
Hope you've already found how to recover lost work from Jupyter notebook work. If not, try the following:
Go to Anaconda Navigator (the green circle!)
Launch a Jupyter Lab
In Jupyter Lab, open a Terminal window
Launch iPython in the terminal by typing ipython and hitting enter
Hit Up arrow
All your code are stored in history and each cell compilation that you would've done in the past shows up there.
Copy+Paste it back to a new Jupyter notebook and you are ready to go again!
If you want to copy/paste.
After running terminal and ipython, page_up yo code you want. Click right button on a mouse, then Watch the elements code. Now you can select code, copy and paste it.
If you don't have Anaconda Navigator you can do access the same data the manual way:
open a new ipython terminal
type %history -g -f history.txt
This will output the entire history of edits which are saved in history.sqlite in your IPython profile folder. You can scroll down to the bottom to find your most recent edits.
You can also just explore the history.sqlite directly, which is located in your IPython profile. The profile should be inside .ipython in your user directory (windows and linux).
Thanks to Christian Long's answer on another question for providing this info.
I just installed jupyter_contrib_nbextensions. However, I could see the navigator tab on only on the small notebooks. Large notebook files do not contain the tab. It is not in the edit tab either.
Would anyone be able to help me on this issue.
Thanks

In Jupyter Notebook, when I highlight text either from within a cell in the notebook or from outside the notebook, Middle-Button click doesn't paste anything as it is supposed to do in many other applications in linux. Is there any setting that would allow one to be able to paste with a Middle-Button click into an Ipython or Jupyter Notebook?
I'm using the notebook in firefox if that matters.
The fact that you're using Firefox definitely matters. See this issue on CodeMirror (CodeMirror is the text editor that Juypter uses): Issue #931
In that thread, it references this Firefox issue: https://bugzilla.mozilla.org/show_bug.cgi?id=846674
It seems as though the issue has only recently been fixed, so it may take a little bit to trickle into CodeMirror. You may want to comment on the issue in CodeMirror to inform them that the issue has been fixed on FF and it might prompt them to investigate.
However, Jupyter doesn't automatically use the most recent version of CodeMirror so again you may have to wait a while. If this issue is truly critical then I suggest switching to another browser.
