Hi all,
After a lot of trying and going back and forth, reinstalling everything
I needed with pip2, I found out that what the actual problem was: for
4.0 and above one needs to install the notebook app seperately by doing:
$ pip install jupyter.
Seem to BigBang working now in a virtual machine, so if someone is going
through same issues as me am happy to share an image.
Cheers,
Niels

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:

Found it (after some searching), it seems the
module 'cycler' is no
longer standard included in matploblib, can be simply installer with:
$ pip install cycler
The quest continuous.

I do not get the notebooks properly running, I have tried several but I
think this comes back (again) to Python versions because what I get when
I simply run the first line (%matplotlib inline) in 'Analyze Senders'is:

Import the BigBang modules as needed. These should be in your Python
environment if you've installed BigBang correctly.

I got similar output with other notebooks. I think this is because
python 3.4 is being called.
I tried:
$ alias python=/usr/local/bin/python2.7
and
$ ipython notebook examples/
But that does not seem to work. Any suggestions on how I can make
ipython (or the notebooks) use python2 ?
