 +===== Jupyter Notebook Tips =====
 +==== Batch ====
 +The process for a batch job is very similar.
 +
 +jupyter-notebook.sbatch
 +<​code>​
 +#!/bin/bash
 +unset XDG_RUNTIME_DIR
 +NODEIP=$(hostname -i)
 +NODEPORT=$(( $RANDOM + 1024))
 +echo "ssh command: ssh -N -L 8888:​$NODEIP:​$NODEPORT `whoami`@fe01.ai.cs.uchicago.edu"​
 +. ~/​myenv/​bin/​activate
 +jupyter-notebook --ip=$NODEIP --port=$NODEPORT --no-browser
 +</​code>​
 +
 +Check the output of your job to find the ssh command to use when accessing your notebook.
 +
 +Make a new ssh connection to tunnel your traffic. The format will be something like:
 +
 +''​%%ssh -N -L 8888:###​.###​.###​.###:####​ user@fe01.ai.cs.uchicago.edu.edu%%''​
 +
 +This command will appear to hang since we are using the -N option which tells ssh not to run any commands including a shell on the remote machine.
 +
 +Open your local browser and visit: ''​%%http://​localhost:​8888%%''​
 +==== Interactive ====
 +  - ''​%%srun --pty bash%%''​ run an interactive job
 +  - ''​%%unset XDG_RUNTIME_DIR%%''​ jupyter tries to use the value of this environment variable to store some files, by defaut it is set to ''​ and that causes errors when trying to run juypter notebook.
 +  - ''​%%export NODEIP=$(hostname -i)%%''​ get the ip address of the node you are using
 +  - ''​%%export NODEPORT=$(( $RANDOM + 1024 ))%%''​ get a random port above 1024
 +  - ''​%%echo $NODEIP:​$NODEPORT%%''​ echo the env var values to use later
 +  - ''​%%jupyter-notebook --ip=$NODEIP --port=$NODEPORT --no-browser%%'​ start the jupyter notebook
 +  - Make a new ssh connection with a tunnel to access your notebook
 +  - ''​%%ssh -N -L 8888:​$NODEIP:​$NODEPORT user@fe01.ai.cs.uchicago.edu%%''​ using the values not variables
 +  - This will make an ssh tunnel on your local machine that fowards traffic sent to ''​%%localhost:​8888%%''​ to ''​%%$NODEIP:​$NODEPORT%%''​ via the ssh tunnel. This command will appear to hang since we are using the -N option which tells ssh not to run any commands including a shell on the remote machine.
 +  - Open your local browser and visit: ''​%%http://​localhost:​8888%%''​
