问题
I've been running a script on jupyter notebooks for about 26 hour; I haven't really been using my computer for anything else, but it needs to run this program that will take ~30 hours to complete. At about 21 hours in, it stopped saving and my terminal had this:
403 PUT /api/contents/[file.ipynb] (::1): '_xsrf' argument missing from POST
where [file.ipynb] is the location of my jupyter notebook. It also says:
'_xsrf' argument missing from post
in the top right part of the notebook again. The program is still running and I don't want to restart jupyter notebook and have to run the program again, as I have a deadline, is there anything else I can do?
I'm using google chrome, but I don't have the LastPass extension or any '%' characters in my code, as another post suggested.
Thanks for any help!

Sorry this probably comes late as far as your deadline is concerned... The easiest way I found is this:

Just open another notebook on the same kernel, and the issue is magically gone; you can again save the notebooks that were previously showing the _xsrf error.
If you have already closed the Jupyter home page, you can find a link to it on the terminal from which Jupyter was started.

The solution I came across seems too simple but it worked. Go to the /tree aka Jupyter home page and refresh the browser. Worked.

I use jupyter notebooks daily and had never experienced this issue before... until today. I had the notebook open all day but it wasn't running anything and then for no apparent reason stopped auto-saving with the '_xsrf' argument missing from POST error message in the top right. FYI - this is a python3 notebook.
I don't know the cause of this problem but I have recently upgraded my python3 version to 3.7.2 and upgraded all of my site-packages to their latest version as of a few days ago which could possibly be the cause.
As for a solution, as suggested in the comment by @AlexK, I opened the same notebook in a new window (different browser in fact), using
jupyter notebook list
in the terminal to get the URL with login token.
This resulted in me having the notebook open and savable again but the information I had entered since the last successful auto-save was missing. Thankfully, my broken instance was still open and working apart from saving so I was able to simply copy and paste the information across then hit save. So, keep the broken instance open if you try this!

When I click 'save' button, it has this error. Based on the answers in this post and other websites, I just found the solution. My jupyter notebook is installed from pip. So I access it by typing 'jupyter notebook' in the windows command line.
(1) open a new command window, then open a new jupyter notebook. try to save again in the old notebook, this time ,the error is 'fail: forbidden'
(2) Then in the old notebook, click 'download as', it will pop out a new windows ask you the token.
(3) open another command window, then open another jupyter notebook, type 'jupyter notebook list' copy the code after 'token=' and before :: to the box you just saw. You can save this time. If it fails, you can try another token in the list

1 workaround to solve this problem is:
Download the notebook which you are not able to save by going to: File --> Download as --> Notebook (ipynb).
Open the downloaded notebook by clicking on the downloaded file on the jupyter browser UI
Now, you should be able to save (or rename) this notebook from jupyter UI

In my case, this problem was solved by clicking 'Kernel' (shown on the top of notebooks) and then 'Reconnect'.
回答7:
I got the same problem (impossible to save either notebooks and .py modules) using an image in the nvidia docker. The solution was just opening a terminal inside jupyter without typing anything but exit once the files were saved. It was done in the same browser/jupyter instance.

回答8:
Open the developer setting and click console and type the following
JSON.parse(document.getElementById('jupyter-config-data').textContent).token
Then try saving the Notebook. The notebook that was not saving previously will save now.
回答9:
This is the easiest way.
I did not need to open a new notebook. Instead, I reopened the tree, and reconnected the kernel. At some point I also restarted the kernel. – user650654 Oct 9 '19 at 0:17
