Hi all,
I was getting several syntax errors in the notebooks and I assumed this
was because ipython was installed for Python 3.4. So I uninstalled
ipython both with apt-get and pip and installed ipython with pip2. Now
my python and ipython seem to be in sync:
$ python
Python 2.7.9 (default, Mar 1 2015, 12:57:24)
[GCC 4.9.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()
$ ipython
Python 2.7.9 (default, Mar 1 2015, 12:57:24)
Type "copyright", "credits" or "license" for more information.
IPython 4.2.0 -- An enhanced Interactive Python.
? -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help -> Python's own help system.
object? -> Details about 'object', use 'object??' for extra details.
In [1]: exit()
but now I'm unable to start the notebooks:
$ ipython notebook examples/
[TerminalIPythonApp] WARNING | Subcommand `ipython notebook` is
deprecated and will be removed in future versions.
[TerminalIPythonApp] WARNING | You likely want to use `jupyter notebook`
in the future

Any suggestions?
Best,
