## INFO: Uncomment the RUN command below for easy and constant notebook URL (just localhost:8888)
#       That will switch jupyter to using empty password instead of a token.
#       To avoid making a security hole you SHOULD in fact not only uncomment but
#       regenerate the hash for your own non-empty password and replace the hash below.
#       You can compute a password hash in any notebook, just run the code:
#          from notebook.auth import passwd
#          passwd()
#       and take the hash from the output
