Unable to get Jupyter Notebook Running After Many Attempts - jupyter-notebook
After many attempts since last week I have been unable to run Jupyter notebook or Lab. I used to run from VS Code from Windows 11 and have many .ipynb files, and without me doing anything atypical that I know about, I now cannot connect to a kernel to run one cell of Jupyter notebook. Unfortunately I am not strong at computing where I have been able to troubleshoot. The kernel waits very long periods of time to connect before timing out. After many searches, I have tried a handful of fixes from other posts but have been unsuccessful.
I have restarted VS Code and my computer without any success. I also tried to open a new notebook session on Jupyter Lab (jupyter lab) and Jupyter notebook (jupyter) and run a simple print('hello world') cell but it still hung up for at least 10 minutes on each attempt and did not connect to a kernel.
Following recommendations on SO and elsewhere, I tried to uninstall and reinstall Jupyter using, for uninstall:
python -m pip uninstall -y jupyter jupyter_core jupyter-client jupyter-console jupyterlab_pygments notebook qtconsole nbconvert nbformat jupyterlab-widgets nbclient
and reinstall using:
pip install jupyterlab.
This did not help.
Following another recommendation, I created a virtual environment, reisntalled jupyter, and tried to launch a notebook instance and still had the same problem.
I tried upgrading jupyter per this SO post.
This solution on SO and many others seem to be related to updating one of the packages to a new version. I have tried a handful of these but have had no success; unfortunately I didn't keep track of all of them.
I followed the guidelines from Issue 9014 but it doesn't seem to apply as I don't know how I can still have an active session open after all of the troubleshooting.
I would be very appreciative if anyone could provide some help. I am a few hours into this and have already started converting all of my notebook files to .py scripts since I am worried I won't be able to resolve this issue.
I'm running:
Python 3.9.1 64-bit
At this point, I cannot run Jupyter at all from VS code or from the command line due to it failing to connect for virtually unlimited periods of time. 6 troubleshooting steps I've taken are included in the 'Details of the problem' section.
In Jupyter notebook, it is stuck on:
'Kernel starting, please wait...".
In VS Code, it is stuck on:
Connecting to kernel: Python 3.9.1 64-bit: Activating Python Environment 'Python 3.9.1 64-bit'
The command line output copied from my last attempt is below:

jupyter-lab does not load jupyter_nbextensions_configurator (but jupyter-notebook does)
Having failed to resolve this after a day and a half of solid effort, I feel I am losing my mind: I have checked config files, rebuilt environments half-a-dozen times, enabled everything possibly relevant, consulted numerous S.O. posts, & github issues and I still can't get it to work. I want to use certain non-core notebook extensions - and be able to debug using xeus-python (in an environment set up for TensorFlow with CUDA - this part at least has always been OK) I have tried numerous combinations of python versions, notebook, conda/pip for installation of jupyter etc. but jupyter-lab will not load jupyter_nbextensions_configurator. However! I discovered by accident that jupyter-notebook does load it (see line 4) - and suddenly I have something to hang a question on. When I run jupyter-notebook, the output begins...

I used a specific notebook version in the end but have no idea whether this is in fact important, since the discovery action was not performed before... but I do wonder whether a specific jupyter version might also be required.

Jupyter Lab not shutting down despite there being no running notebooks shown
I'm trying to run Jupyter Lab but I noticed that I can't shut down the previous session. When I run Jupyter Lab, I do the following jupyter-lab --no-browser --ip xxx.xxx.xxx.xxx in my Linux server and paste the output address to a Chrome browser. Normally when I'm done and I shut down the terminal everything works fine, but now it's saying: Shutdown this Jupyter server (y/[n])? y [C 2021-05-25 20:15:41.324 ServerApp] Shutdown confirmed [I 2021-05-25 20:15:41.326 ServerApp] Shutting down 2 kernels [I 2021-05-25 20:15:41.327 ServerApp] Kernel shutdown: abcdefgh-a891-4be3-b4ae-ee88ca5ff450 [I 2021-05-25 20:15:41.330 ServerApp] Kernel shutdown: ijklmnop-358b-4a24-be8d-214046ffd5eb [I 2021-05-25 20:15:41.937 ServerApp] Shutting down 0 terminals When I press Ctrl + C I get the following message: [C 2021-05-26 08:24:45.648 ServerApp] received signal 2, stopping and nothing happens afterwards.

Go to the path /usr/share/ (the path to Jupyter directory showing in the error where nbconvert is under that) and remove the Jupyter directory by typing rm -rf Jupyter and run the notebook again.
Remote Jupyter Notebook/ Jupyter Lab cannot connect to Kernel without ssh tunnelling
I am getting a problem in opening remote Jupyter Lab/ Jupyter Notebook, it is not connecting to the kernel, I've mentioned the setup steps, problem coming and attempted fixed below. Any solutions, suggestions, or directions are greatly welcomed. Thanks in advance.
Setup Steps Followed:
I am using a fresh Anaconda 3 install in Ubuntu 20.04 LTS. I set up the Jupyter Notebook/ Jupyter Lab to be accessed remotely using the method provided in this answer (IP of that computer is 172.17.25.75), I've quoted the steps below:
Step 1. jupyter notebook --generate-config
Step 2. gedit /home/koushik/.jupyter/jupyter_notebook_config.py and edit the values c.NotebookApp.allow_origin = '*' and
c.NotebookApp.ip = '0.0.0.0
Step 3. Allow port sudo ufw allow 8888
Step 4. Set Password jupyter notebook password
Step 5. Start Jupyter Lab using jupyter lab --no-browser or Start Jupyter Notebook using jupyter notebook --no-browser
And access the Jupyter Lab/ Jupyter Notebook from my computer using
http://172.17.25.75:8888 in the browser.
I am behind my Institue proxy server. When I connect to Jupyter Lab or Jupyter Notebook using ssh tunneling ssh -N -f -L localhost:8889:localhost:8888 zuddler#172.17.25.75 and access localhost:8889 everything works fine. But when I am not tunneling and accessing them using IP, the following errors occur.
Problem with Jupyter Lab:
Upon running the command jupyter lab --no-browser below is the terminal output:

Upon opening http://172.17.25.75:8888 in the browser and starting the previously created python 3 notebook, it gave the error Kernel not found asked to select a kernel
screenshot 4
on clicking Set Kernel, it gave a connection failed error as below
screenshot 5
but again a kernel was started and the terminal showed the below line (similar to Jupyter Lab)

Again, upon executing jupyter kernelspec list, one kernel detail was returned
(base) zuddler#silplab:~$ jupyter kernelspec list
Available kernels:
python3 /home/zuddler/anaconda3/share/jupyter/kernels/python3
Attempted Fixed
Try 1. Tried updating jupyter using conda update jupyter, it returned
(base) zuddler#silplab:~$ conda update jupyter
Collecting package metadata (current_repodata.json): done
Solving environment: done
# All requested packages already installed.
So, I tried to check if I have the lastest versions of conda and jupyter and it returned:
(base) zuddler#silplab:~$ jupyter --version
jupyter core : 4.6.3
jupyter-notebook : 6.1.4
qtconsole : 4.7.7
ipython : 7.19.0
ipykernel : 5.3.4
jupyter client : 6.1.7
jupyter lab : 2.2.6
nbconvert : 6.0.7
ipywidgets : 7.5.1
nbformat : 5.0.8
traitlets : 5.0.5
(base) zuddler#silplab:~$ conda --version
conda 4.9.2
To check if there is some path issue, I checked using which as mentioned here and it returned
(base) zuddler#silplab:~$ which jupyter-notebook
/home/zuddler/anaconda3/bin/jupyter-notebook
(base) zuddler#silplab:~$ which jupyter-lab
/home/zuddler/anaconda3/bin/jupyter-lab
(base) zuddler#silplab:~$ which python
/home/zuddler/anaconda3/bin/python
so, the paths were correct.
I also set c.NotebookApp.allow_remote_access = True in .jupyter/jupyter_notebook_config.py file (as mentioned here), but it did not fix the issue.
Try 2. To be sure that the kernel had the correct python path, I checked the kernel.json file, the path to python 3 was correct
(base) zuddler#silplab:~$ cat /home/zuddler/anaconda3/share/jupyter/kernels/python3/kernel.json
{
"argv": [
"/home/zuddler/anaconda3/bin/python",
"-m",
"ipykernel_launcher",
"-f",
"{connection_file}"
],
"display_name": "Python 3",
"language": "python"
}
I further tried to rename the kernel folder as mentioned in this jupyter-notebook doc
A path ending in ipykernel/resources, like in the example above, is this default kernel. The default often does what you want, so if the python3 kernelspec points somewhere else and you can’t start a Python kernel, try deleting or renaming that kernelspec folder to expose the default.
the executed commands and outputs are below, it revealed the default kernel:
(base) zuddler#silplab:~$ cd /home/zuddler/anaconda3/share/jupyter/kernels/
(base) zuddler#silplab:~/anaconda3/share/jupyter/kernels$ ls
python3
(base) zuddler#silplab:~/anaconda3/share/jupyter/kernels$ mv python3 python3_bak
(base) zuddler#silplab:~/anaconda3/share/jupyter/kernels$ cd ~
(base) zuddler#silplab:~$ jupyter kernelspec list
Available kernels:
python3 /home/zuddler/anaconda3/lib/python3.8/site-packages/ipykernel/resources
python3_bak /home/zuddler/anaconda3/share/jupyter/kernels/python3_bak
but I am getting the same errors.
Try 3. I also tried to follow the suggestions referenced in this question, but to no benefit.

Looks like this issue was fixed in Jupyter 6.0.1
So the question becomes: can I force-install jupyter 6.0.1?
As the initial question has now provoked a second question, I now ask this new question here: How to force `conda` to install the latest version of `jupyter`?
Alternatively I can manually provide the missing file, but I'm not sure where. I've asked here: Where does Jupyter install site-packages on macOS?
Research:
https://github.com/jupyter/notebook/pull/4772 "add missing react-dom js to package data #4772" on 6 Aug 2019
minrk added this to the 6.0.1 milestone on 18 Jul
Ok, so can I get Jupyter Notebook 6.0.1?
brew cask install anaconda downloads ~/Library/Caches/Homebrew/downloads/{LONG HEX}--Anaconda3-2019.07-MacOSX-x86_64 which is July, and conda --version reports conda 4.7.10. But this is for Anaconda which is the Package Manager.
> conda list | grep jupy
jupyter 1.0.0 py37_7
jupyter_client 5.3.1 py_0
jupyter_console 6.0.0 py37_0
jupyter_core 4.5.0 py_0
jupyterlab 1.0.2 py37hf63ae98_0
jupyterlab_server 1.0.0 py_0
So that's a bit confusing. No jupyter notebook here.
> which jupyter
/usr/local/anaconda3/bin/jupyter
> jupyter --version
jupyter core : 4.5.0
jupyter-notebook : 6.0.0
qtconsole : 4.5.1

jupyter lab : 1.0.2
nbconvert : 5.5.0
ipywidgets : 7.5.0
nbformat : 4.4.0
traitlets : 4.3.2
Ok, so it appears jupyter-notebook is in jupyter which is maintained by Anaconda.
Can we update this?
https://jupyter.readthedocs.io/en/latest/projects/upgrade-notebook.html
> conda update jupyter
:
Alas jupyter --version is still 6.0.0
I fixed this by updating both jupyter on pip and pip3 (just to be safe) and this fixed the problem using both pip install --upgrade jupyter and pip3 install --upgrade jupyter --no-cache-dir I believe you can do this in the terminal as well as in conda's terminal (since conda envs also have pip)
As per Where does Jupyter install site-packages on macOS?, I locate where on my system jupyter is searching for this missing file: > find / -path '*/static/components' 2>/dev/null /usr/local/anaconda3/pkgs/notebook-6.0.0-py37_0/lib/python3.7/site-packages/notebook/static/components /usr/local/anaconda3/lib/python3.7/site-packages/notebook/static/components And as per https://github.com/jupyter/notebook/pull/4772#issuecomment-515794823, if I download that file and deposit it in the second location, i.e. creating: /usr/local/anaconda3/lib/python3.7/site-packages/notebook/static/components/react/react-dom.production.min.js ... now jupyter notebook launches without errors. (NOTE: Being cautious I have also copied it into the first location. But that doesn't seem to have any effect.)
