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
