yesterday i updated my anaconda to version (1.9.12)
im getting the following error & 500 internal error when using notebook
An invalid notebook may not function properly. The validation error was:
Notebook validation failed: 2 is less than the minimum of 3:
2
the code is running but i cant save,edit or download notebooks
i looked online and someone suggested to run: conda update --all
i did but still not working i have restarted my pc several times now
It looks like this error is sometimes caused by old nbformat versions?
See https://github.com/jupyter-widgets/ipywidgets/issues/1352
Try listing the version you have installed, and if it's 2, then maybe try updating (conda update nbformat)

I had problems opening my jupyter notebook so I deleted it and downloaded it again, but now every time I try to open a notebook "500: internal server error" appears on my screen. I have already tried upgrading jupyter and I have an assignment pretty soon where I have to use jupyter notebook so help is really appreciated!
I have already tried upgrading jupyter, which did nothing noticeable.I have an assignment pretty soon where I have to use jupyter notebook so help is really appreciated!
I'm copying and pasting an answer that I found here and worked for me. Install this:
jinja2==3.0.3
nbconvert==6.4.4
with pip you can use this command:
pip install jinja2==3.0.3 nbconvert==6.4.4
Here are my steps for installing Jupyter Lab and the Git extension, and then trying to troubleshoot the extension version mismatch problem:
Specs: MacOS Mojave 10.14.6, Jupyter Lab 3.0.5
1. I installed Jupyter Lab using pip3 install jupyterlab
2. I installed the Jupyter Lab Git extension directly from Jupyter Lab's Widgets Manager:
3. After doing so I received additional instructions:
4. I clicked 'OK' and then ran pip3 install jupyterlab-git
5. Back in Jupyter Lab, it said a build was needed to include the latest changes, so I selected 'Rebuild'
6. The build was successful, and I clicked on 'Save and Reload'
7. Upon reloading, I received the following message:
8. I followed the instructions and ran pip3 install --upgrade jupyterlab-git
9. I went back to Jupyter Lab and clicked "Dismiss" on the message.
10. I closed and reopened Jupyter Lab via terminal. After reopening, the same "failed to load" message appeared.
11. I then found this link troubleshooting a similar issue.
12. I followed the advice by running all of the below commands (with pip3, and fixing spelling errors):
13. The user then suggests the following to make sure everything worked OK. So I closed Jupyter Lab again, and ran all of the following:
14. Running jupyter serverextension list I get the following, which I think looks OK:
15. Then I ran pip3 list and get back: jupyterlab-git 0.23.3 (so Git extension version 0.23.3, which according to the GitHub extension page at the time of me writing this is the most current (non-beta) version).
16. Then I ran jupyter labextension list and see nothing related to the Git extension, which is not expected per the above user's screenshots (it's supposed to show the Git Extension here):
17. Now here's one last thing: When I go back and install the Git extension via Jupyter Lab's Extension Manager (like I had done initially), and then I run jupyter labextension list again, I see that the Git extension is the "pre-release" version v0.30.0b1, which would likely be why way back in step 7 I got the error message that the frontend and backend extensions did not match.
And here's where I'm stuck. I can't seem to get these two extension installations to match (or to ever have the extension icon show up in the side panel).
And around and around I go...
EDIT: Possible solution.
After reading my own question here, I thought maybe I should try to install the "pre-release" Git extension version to match the other version, and that seems to have worked. I just didn't think it was best practice to use "pre-release" or beta versions, so that had not occurred to me until just now. So I'm not going to "solve" my own question here, because I'm just not sure this is the best solution... But is it?
I ran this: pip3 install jupyterlab-git==0.30.0b1 and now I'm no longer seeing any version mismatch errors, and the Git extension icon is finally showing up in the side panel.
They versions need to match as per #779
What worked for me was:
pip install --upgrade --pre jupyterlab-git
I am getting this error I am just playing with Linux commands and I noticed a change suddenly that my conda is not responding so I cannot able to activate my env, make new env, or open Jupiter notebook. I have many projects in my system so how to mitigate this error
before this error when everything is right I always have a (base) name in front of my terminal like the below one
(base)rahul#linux:~$ conda
but now I am getting this only with errors
rahul#linux:~$ conda

I had the same error but on a plain Debian 10, without conda (and without action on my part).
Python3.5 was working well but python3.7 (linked to python3) was crashing with the same error. I tried every PYTHONPATH I could think of, but nothing worked, and I don't think it could do anything because python3 -vvv shows that the encoding package is well found and imported.
Then I thought it was my locales. (some pretty interesting infos here https://vstinner.github.io/python37-new-utf8-mode.html but didn't found my answer)
At the end all I could do to fix it, was to reinstall python3.7 from source (with apt it didn't work), and then reinstall all needed packages. (if you're missing lsb_release check this answer : it's in /usr/share/pyshared)
I have just started out on R and have hit a roadblock. I can't seem to run the edit() command in RStudio.
Here's what I have tried
1. Changing the RSTUDIO_WHICH_R environment variable
2. Fixing the warning messages which were displayed every time I opened the RStudio.
3. I have even reinstalled R and RStudio.
I have posted the image of the error message that I get on my Console window.
I am working on MacOS High Sierra
Any help is appreciated.
I have installed Xcode as well and the error has changed as shown in the second image.

You may be missing or have to reinstall XQuartz 2.7.11, install it first then try running edit command.If it doesn't work then do the following.(This happens sometimes during an update)
1) Find the location of libcario.2.dylib using locate command from terminal/iterm-2 . Use command locate libcario.2.dylib, you should receive something similar with this location: /usr/X11/lib/libcario.2.dylib. Someone can use cd,find to locate the location as well.
2) If the location is found then use ln -s to create a link like below:
sudo ln -s /opt/X11 /usr/X11
when I try to run the executable for an R 3.2.2 installer downloaded from a cran mirror, I get an error which says:
"Unable to execute file in the temporary directory. Setup aborted.
Error 5: Access is denied."
I've tried several solutions found here: http://answers.microsoft.com/en-us/windows/forum/windows_7-performance/unable-to-execute-files-in-the-temporary-directory/0d441663-6167-420d-b936-53f9c3d17898?auth=1
None have prevented the error. Please assist me!
After following these solutions to no avail, I decided to turn my firewall BACK ON and play some league of legends. I clicked the R-3.2.2-win.exe just for giggles and what do you know, the installer RAN PERFECTLY...
