Usage:
jupyter lab HOST PORT [DIR]
jupyter tunnel HOST PORT
jupyter stop HOST PORT
jupyter open PORT
jupyter info [PORT]
jupyter backup
This command can start a jupyter notebook on a remote machine and
use it in your browser.
Arguments:
USER The username on the remote machine
HOST The hostname of the remote machine
PORT The port of the remote machine
DIR The directory where the notebooks are located
Description:
Step 1: Setting up a .bash_profile file
If you have your python venv set up you need to add it to the
.bash_profile on your remote machine. A possible
profile file could look as follows:
if [ -f ~/.bash_aliases ]; then
. ~/.bash_aliases
fi
export PATH=$HOME/ENV3/bin:$PATH
source $HOME/ENV3/bin/activate
Step 2: Start the remote notebook server in a terminal
Note: After the start you will not be able to use that terminal
cms jupyter start HOST PORT
Thsi command will aslo establich an SSH tunel and open in
the web browser jupyter lab
