+This installs the most recent versions these three packages. If you install the
+packages via ubuntus package manager, you will get older version. Ubuntu's
+packages can hide the more up-to-date ones installed by pip3. My personal
+recommandations is to always use pip and never install python packages via
+ubuntus package manager if you want to use recent version of the packages.
