A few more notes while installing and first usage (1 and 2), and then a
question for where I am stuck now (3).
1.
To clean things up a bit and start fresh I decided to remove my bigbang
folder. After I tried to reinstall I had quite some issues with running
pip install -r requirements.txt
especially where it came to the packages snakefood and pydot. Which is
somewhat surprising since they (1) already are installed and (2) I have
installed them before (3) and many of them are availble from the Debian
repos. I simply uncommented them from requirements.text and went ahead,
and finally simply went ahead and ran $python setup python develop.
The error messages from $sudo pip install -r requirements.txt - FYI:
Collecting snakefood (from -r requirements.txt (line 19))
Using cached snakefood-1.4.tar.gz
Complete output from command python setup.py egg_info:

2.
I could not simply run 'source activate bigbang' as indicated in the
readme.md, I first had to run
$ virtualenv venv
and then
$ source venv/bin/activate bigbang
3.
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:
[code]

Import the BigBang modules as needed. These should be in your Python
environment if you've installed BigBang correctly.
[/code]
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 ?
Cheers,
Niels

Hi all,
Have been toying some time setting up BigBang now. First of all I would
like to thank you people for developing this and making it FLOSS.
Secondly I wanted to make a few short notes on the installation process
for me, working on Debian 8.0 Jessie (Stable).
Installation has been a bit of an issue because of quite a few issues
with different Python versions. There were some dependencies that could
not be resolved in Python 2.6 and 2.7 through the debian repos, so I
went with Python 3.4, which of course resulted in issues when I ran the
Python command, and not calling python3 (at several stages, most
recently in the notebooks (because imports failed)).
Probably a bit of a n00b thing, but just wanted to flag it. Will make
more notes during installation. Hope it is useful :)
Something that might be a bit more interesting is why I am actually
installing this software: I am researching prevelance and penetration of
rights language in Internet Governance forums, such as ICANN and the
IETF, which is partially based on my involved with both bodies to push
for human rights (http://icannhumanrights.net and https://hrpc.io) and
my PhD at https://data-activism.net/.
So expect more traffic and questions from me here soon.
Cheers,
Niels
