#!/usr/bin/env bash
# This script will start JupyterLab server in the background (https://stackoverflow.com/a/44222911)
# There are some environment variables that you can set when starting the container to override the defaults:
#
#    `--env JUPYTER_ROOT=/home/user`
#    `--env JUPYTER_PORT=8888`
#    `--env JUPYTER_PASSWORD=nvidia`
#    `--env JUPYTER_LOGS=/data/logs/jupyter.log`
#
# The `/data` location is automatically mounted to your `jetson-containers/data` directory.
