What I want to do is connecting Jupyter Notebook to a remote HPC system.
So, firstly I get the access to the HPC with the following line of code:
ssh -o TCPKeepAlive=true a06upi0e#cometa.hpc.cineca.it
Then, I insert the password and I can have the access to the system.
I load anaconda module with the following script:
module load anaconda/3.7
I activate 'myenv' environment:
conda activate myenv
I run this code to access jupyter notebook:
(myenv) [a06upi0e#login09 ~]$ jupyter notebook --no-browser --ip=127.0.0.1 --port=8888
This is the output:

What should I do? I tried changing ports but without succeeding.

I would just like to understand what's happening below. I am using MacOs and recently switched from bash to zsh. And then I installed jupyterlab-lsp. Can you please enlighten me?

The issue is because jupyter server is unable to find the language servers. As in my case, jupyter is installed and maintained using conda environment(miniconda) under /opt/miniconda3/, whilst my nodejs is sitting under /usr/local/. Ideally, if you are already using conda manager, you will want to uninstall nodejs completely and reinstall it using conda. Otherwise, remove the entire anaconda/conda and then reinstall python (https://www.python.org/downloads/release/python-381/) and jupyter using either pip or brew depending how/where you installed nodejs.
I was able to resolve my issue following below steps:
1.) Completely uninstall node js. I was able to do it by running nvm uninstall <version> or if you are using homebrew, run brew uninstall node and then rm -f /usr/local/bin/npm on terminal. Additionally, you can follow below reference: How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X)
2.) Reinstall nodejs. conda install -c conda-forge nodejs
3.) Install the language servers. See reference: https://github.com/krassowski/jupyterlab-lsp/blob/master/LANGUAGESERVERS.md#installing-language-servers
4.) Restart terminal and run jupyter lab.
Now this is the best answer that I have that was able to resolve my issue.
I am unable to access jupyter notebook after starting my virtual machine on Google cloud. I type the code below on the shell prompt:
jupyter notebook
This returns some information about the notebook server including:
[I 02:28:31.858 NotebookApp] The Jupyter Notebook is running at:
[I 02:28:31.858 NotebookApp] http://(my-fastai-instance2 or 127.0.0.1):8081/
However, when I try to access jupyter notebook at this address, the browser just returns a message saying it is unable to establish connection at that server address.
Resolved using:
gcloud compute ssh <zone> <instance name> <port number>.
Thank you for your help.
Maybe you need try in web browser this address:
http://localhost:{your port}/tree
insatall localtunnel :
localtunnel exposes your localhost to the world for easy testing and sharing! No need to mess with DNS
npm install -g localtunnel
after that run this command on port you are using
lt --port 8000
if the url wasn't working :
go set the configuration mentioned in the message from jupyter :
c.NotebookApp.allow_remote_access = True
in jupyter_notebook_config.py, e.g. /etc/jupyter/jupyter_notebook_config.py in your user image if using container-based deployment.
Try like this
gcloud compute ssh --zone=YOURZONE jupyter#INSTANCENAME -- -L 8080:localhost:8080
After login to cloud with that, open browser and type localhost:8080 and you should have jupyter.
This also should work by tunneling jupyter via ssh -i ~/.ssh/google_compute_engine -nNT -L 8888:localhost:8888 vm_external_IP and then localhost:8888 in your browser
I'm configuring jupyter notebook on a linux server(Red Hat 4.8.5).I want to use a remote client to visit jupyter notebook.
First of all,I generated a config file:
jupyter notebook --generate-config
And then I modified the config file /root/.jupyter/jupyter_notebook_config.py:
c.NotebookApp.ip="0.0.0.0"
c.NotebookApp.allow_origin='*'
c.NotebookApp.open_browser=False
c.NotebookApp.password=u"sha1:16715d2ac300:ee938c81001cfd0841f8bf1441bd02038b62965e"
c.NotebookApp.port=9999
c.NotebookApp.notebook_dir='/home/jupyter_notebook'
Finally,I run the jupyter notebook:
jupyter notebook --config /root/.jupyter/jupyter_notebook_config.py --allow-root
However,The jupyter was just running the server at localhost:
[root#localhost home]# jupyter notebook --allow-root --config /root/.jupyter/jupyter_notebook_config.py

When I use the same config file to run jupyter notebook on my Aliyun server(Ubuntu 16),it worked:

[I 17:48:59.389 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
I don't know what the problem is.I've searched a lot,but just cannot find a solution.
Any suggestions will be welcomed.
I've solved the problem. It's because my server's 9999 port is not opening to the Internet.
I am trying to activate Jupiter with xeus-cling C++ kernel on windows 10
I did the following:
Installed a brand new Miniconda
Created a new environment
Installed Jupyter (unisng conda install)
Installed xeus-cling using the command :
conda install xeus-cling notebook -c QuantStack -c conda-forge
I activated the Jupyter notebook and got the following kernel error

What can I do to solve the problem ?

Afraid its just a matter of support. Windows is not yet supported... you will have to use linux or OS X for now.
I can not use jupyter notebook suddenly. I just updated the system of my mac, before I started notebook. Following is the error.

I think the issue is due to MAC upgrade to 10.12.5. To fix the issue follow below steps
Step1: Open the terminal and go to ~/.jupyter folder
Step2: Create a config file jupyter_notebook_config.py and write the following command inside it and save the file in the same location:
c.NotebookApp.browser = u'safari'
Step3: Come out and in terminal type jupyter notebook, it should work now.
