From the moment of writing, it is normal to receive these messages. It just means you are missing python packages. I suggest installing them as follows: pip install --user [package] . Others he may complain about are listed here :
jinja2, needed for the notebook sphinx, needed for nbconvert pyzmq, needed for IPython's parallel computing features, qt console and notebook pygments, used by nbconvert and the Qt console for syntax highlighting tornado, needed by the web-based notebook nose, used by the test suite
