I was working in a jupyter notebook until it froze. It wouldn't save or shut down so I restarted my computer. I launched jupyter notebook from an anaconda prompt, my folder directory opens per usual. When i tried to open the notebook from before, I get an error loading screen that says permission denied: (name of notebook).ipynb. I hit close and the notebook shuts down.
I checked the folder permissions, I have full control. I can create a new ipynb without any issues. I can open other notebooks without any problem in the same folder. I tried to run a trust notebook through the anaconda prompt and it says the notebook is missing.
I need to recover this particular notebook as it has all my work. Help! Any ideas? Thanks in advance.
I work in the anaconda prompt in an environment other than the root, so this answer using sudo chmod doesn't work for me.
I had possibly the same problem. In my case the problem was that jupyter notebook must have crashed or had some problem whilst autosaving.
As a result, in the folder where the notebook is saved there's a temporary file called ".~nameofnotebook.ipynb".
This file didn't show up in jupyter notebook, but only in the explorer. I deleted the notebook file and renamed the temporary file to delete the ".~" prefix. Make sure to save a copy of the notebook file before deleting anything in case your problem is different.
The renamed temporary file opens fine and none of my data was lost.
Change the name of the file and you are good to go bro..

I have a Jupyter Notebook open in Jupyter Lab. I run black to reformat the code in the open Jupyter Notebook. If I try to save the file, Jupyter Lab raises
"notebook.ipynb" has changed on disk since the last time it was opened
or saved. Do you want to overwrite the file on disk with the version
open here, or load the version on disk (revert)?
How can I revert the Jupyter Notebook without try to save it?
I found the answer at File > Reload from Disk.
When I run jupyter notebook I get: Your file couldn’t be accessed It may have been moved, edited or deleted in chrome.
I checked jupyter --path and looked at the directories listed and most of them don't exist, I tried reinstalling and I'm getting the same issue.
I manually copied the url with the token and I was able to run jupyter notebook but I can't find the config, data or runtime.
Edit: I previously installed iJava but didn't reinstall but it appears when I run jupyter notebook making me think it didn't uninstall properly. Not sure how else to uninstall it considering I can't find the installation path.
No problem in other directories. Is there an environmental variable or something else I need to erase?
Deleted cache file...
OK, I think I need be much clearer here.
First software:
MacOS Catalina 10.15.6
jupyter notebook 6.0.3
Python 3.8.3
IPython 7.16.1
jupyter notebook is installed and runs fine.
jupyter notebook runs just fine in any user directory on the computer except exactly one.
There is nothing obvious in this directory that shouldn't be there. An 'ls -al' shows nothing but some .py files.
I can create a jupyter notebook in this directory, but the kernel crashes and won't restart. I can rename the directory, rename the jupyter notebook, but the behavior persists beyond everything I have been able to reset including a cold computer restart. It is reproducible and happens every time.
This behavior is not seen in any other directory.
My question: are there environmental variables or caches stored not visibly in the directory (obviously) that are responsible for this incredibly annoying behavior and how can I reset them?
Problem solved: jupyter notebooks apparently uses some reserved names for local directory .py files when starting up the notebook. So far I've found that "string.py" and "decorator.py" cannot be in the startup directory unless they contain the expected data (looks like it needs to be related to some template info)
To start-up a kernel
You first activate your virtual environment:
For instance: conda activate vision
Second, you type jupyter notebook
as stated here
I recently downloaded Anaconda on my Windows and am trying to use the Jupyter notebook. However, when I open Jupyter, the it seems to be full of odd files.
Odd Files
I have tried to change the Jupyter home directory by changing the "Start in" in the Jupyter file but the home directory remained unchanged.
Start in
There are two problems here. The first being that there are a large number of files and running the jupyter notebook makes my computer run slow. Second that when I try to add folders, I get the error that I do not have ownership to do so.
Simple fix. I was previously running jupyter from the command prompt but running it through the anaconda navigator fixed it.
I had a hardware crash while running a Jupyter notebook. After repairing the system and trying to restart the notebook, I got the following error message:
Error loading notebook
Unreadable Notebook: D:\Eddy\Documents\1604 Udacity\1612 Self-driving car Nanodegree\P4\P4 Eduard van Kleef.ipynb NotJSONError("Notebook does not appear to be JSON: ''...",)
Does anyone know of a way to revert to any of Jupyter's previous 'checkpoints'? Or of a way to at least partially restore a JSON?
If you are lucky then the ipynb file is corrupted but still there. In that case you can try opening it in a text file and copying the contents to a new notebook. But check the size of the file. If it is zero bytes, then there is nothing there!
This actually happened to me when my server ran out of memory and somehow the notebook got completely erased. Totally sucks.
Try this
jupyter nbconvert filename.ipynb --clear-output
It worked for me since it has corrupted because of Plotly behavior with some big data.
in your file directory that contains your ipynb file there is a folder called '.ipynb_checkpoints'. this folder does not show in the jupyter application so find it through windows explorer.
inside there's will be a file called urfilenamehere-checkpoint.ipynb
copy paste it to your file directory and open through the jupyter application it should probably work.
if your corrupted file is 0B, you definitely have to rely on the checkpoints.
do not create a new notebook with the same name it will overwrite the checkpoint.
