Jupyter Notebooks

caution

These instructions cover jupyter-notebook 7.1.2, though should be easily adaptable for both newer versions and jupyter-lab.

Pre-requisites#

This tutorial assumes you have already completed the set up of Miniconda covered here. Throughout this exercise, it might be helpful to refer to those instructions if you get stuck.

note

The examples below use my UWNetID (finchkn) and a compute node that was available during the development of this documentation (n3097); you will have to replace finchkn with your UWNetID and probably n3097 with a different compute node name when required.

Set Up#

important

Before beginnning this exercise, please select a random number between 4096 and 16384 for your Jupyter-Notebook server to start on. It is important that this number is unique and does not conflict with either another user or an existing service on your machine. From this point out, we will use 9195 as an example.

Start an interactive job on a compute node with salloc.

[finchkn@klone-login03 ~]$ salloc -A uwit -p ckpt --time=4:00:00 --mem=10G -c 4
    salloc: Pending job allocation 1546486
    salloc: job 1546486 queued and waiting for resources
    salloc: job 1546486 has been allocated resources
    salloc: Granted job allocation 1546486
    salloc: Waiting for resource configuration
    salloc: Nodes n3097 are ready for job
[finchkn@n3097 ~]$

Install and Configure Jupyter Notebook#

Create a conda environment and install required packages.

[finchkn@n3097 ~]$ conda create -n jupyter-notebook
[finchkn@n3097 ~]$ conda activate jupyter-notebook
(jupyter-notebook)[finchkn@n3097 ~]$ conda install -c conda-forge notebook

Set up a password for your Jupyter Notebook Session. This will remain your password every time you log in - Remember it.

(jupyter-notebook)[finchkn@n3097 ~]$ jupyter-notebook --generate-config
(jupyter-notebook)[finchkn@n3097 ~]$ jupyter-notebook password
    Enter password:
    Verify password:
[JupyterNotebookApp] Wrote hashed password to ~/.jupyter/jupyter_server_config.json

Start Jupyter Notebook Sessions#

Remember, we chose 9195 as our random number for this exercise. You can choose any number between 4096 and 16384 for your connection, and replace 9195 with that number in the following examples.

Start jupyter notebook.

(jupyter-notebook)[finchkn@n3097 ~]$ jupyter notebook --port 9195 --ip 0.0.0.0
    [I 2024-04-01 16:05:45.434 ServerApp] Extension package jupyter_lsp took 0.9552s to import
    ...
    [I 2024-04-01 16:05:58.515 ServerApp] Jupyter Server 2.13.0 is running at: 
    [I 2024-04-01 16:05:58.515 ServerApp] http://n3097:9195/tree   
    [I 2024-04-01 16:05:58.515 ServerApp]     http://127.0.0.1:9195/tree
    [I 2024-04-01 16:05:58.516 ServerApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
    ...

Keep this window open. Messages about your session will be printed there.

Now open a new Terminal/Windows Powershell/PuTTy window and start an ssh tunnel from your local computer to the jupyter notebook session that you initiated on the klone compute node.

kristenfinch@Kristens-MBP-3 ~ % ssh -L 9195:n3097:9195 finchkn@klone.hyak.uw.edu
    (finchkn@klone.hyak.uw.edu) Password:

    Enter a passcode or select one of the following options:

    1. Duo Push to XXX-XXX-XXXX
    2. Phone call to XXX-XXX-XXXX

    Passcode or option (1-2): 1
    Success. Logging you in...

                                     |___/

Next direct your browser to http://localhost:9195. You will be prompted for the password you set with jupyter-notebook a few steps ago.

Provide Password

The browser will open the Jupyter Notebook Session and you will see contents of the directory on klone.

Files

Your token for this session will also appear in the terminal window connected to the compute node.

[I 2024-04-01 16:13:54.521 ServerApp] User 99999somee92ftoken1bfhere9999999 logged in.
[I 2024-04-01 16:13:54.522 ServerApp] 302 POST /login?next=%2Ftree%3F (99999somee92ftoken1bfhere9999999) 462.64ms

While the connection is open. Another option is to direct your browser to http://localhost:9195/?token=99999somee92ftoken1bfhere9999999

Ending your Session#

End your session from the browser with the File Menu and "Shut Down" or "Log Out."

End Session

Then go to your terminal window to the compute node and use Control + C to end the session there.

$ ^C
