Jupyter notebook error Windows 10

Question

Problem:

Jupyter is not able to save, create (I imagene delete) any file type. But I can load them fine

An example of creating file

Creating File Failed An error occurred while creating anew file.

''' Unexpected error while saving file: untitled.txt [Errno 2] No such file or directory: 'C:\Users\me\Documents\jupyter_notebooks\untitled.txt' '''

Tried: Still the same problem

I double checked the folder location and it matches

C:\Users\me\Documents\jupyter_notebooks

I also tried: It install and runs, able to open and read but no changes allowed

pip3 install --upgrade --force-reinstall --no-cache-dir jupyter

System:

• Windows 10
• Python environment: 2.7 & 3.5
• package manager: pip / pip3

Possible contributing factors: Made some system changes two days ago, and since the problem started. I believe is a permission issue. I recall deselecting a "permissions check box" for executing scripts. but it only seemed to affect Jupyter

Not acceptable solutions:

"Try Anaconda", "Reinstall windows" - the system was working fine and continues to work, with the exception of Jupyter enability to make changes

Thank you in advance

Answer 1

I am the author of the question...

The problem was a permissions issue, as I mentioned earlier, I did modify the system and could not remember what I had done to prevent Jupyter Notebook from working as before. I spent the better part of three days researching the problem and could not find an answer, in frustration, today I posted the problem. And with the comments and suggestion from a couple of the users I was able to take a better look at the problem and try a few different approaches.

I had enabled a feature in "Windows Defender Security Center" that prevented Jupyter from working as before, preventing me from running Notebooks in different locations, more specifically the "Documents" folder.

Should this happen to you:

1. Go to "Windows Defender Security Center"
2. Scroll & Click on "Virus & threat protection settings"
3. Scroll down to "Controlled folder access"
4. Make sure is Disabled

This was the "global" solution I was looking for

That should fix a similar problem

Answer 2

if your OS is Windows10, may you have to flow this

1. mouse right click the "Anaconda Navigator" icon
2. and pop-up "Anaconda Navigator" icons properties
3. click the "detail properties"
4. Check the checkbox labeled "Run as administrator" as shown below in the text "Select advanced properties for this shortcut" and save it.

Answer 3

As Enrique Bruzual mentioned above, this behavior can be caused by having "Controlled folder access" enabled in the Windows Defender Security Center. Disabling it fixes the issue.

If you'd like to leave "Controlled folder access" enabled, follow Enrique's steps 1-3, which I have quoted here.

1. Go to "Windows Defender Security Center"
2. Scroll & Click on "Virus & threat protection settings"
3. Scroll down to "Controlled folder access"

Then:

4. Click "Allow an app through Controlled folder access".
5. Click on "Add an allowed app" and select your python.exe, jupyter.exe, and jupyter-notebook.exe files. You can find python.exe in your main Python installation directory and the other two in the "Scripts" subdirectory of your main Python installation directory.
6. Restart jupyter if it was running when you made these changes.

You have to add the files one at a time, so it will take a bunch of clicking. I was able to save my jupyter notebooks without issue after doing this.

NOTE: If you have both Python 2 and 3 installed, you must do this for each Python installation.
