[Bigbang-user] question + starting user notes

Fri Apr 29 07:19:55 PDT 2016

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:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/tmp/pip-build-_x_eycqn/snakefood/setup.py", line 19
except IOError, e:
^
SyntaxError: invalid syntax

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in
/tmp/pip-build-_x_eycqn/snakefood/

and

Collecting pydot (from BigBang==0.1->-r requirements.txt (line 1))
Using cached pydot-1.0.2.tar.gz
Complete output from command python setup.py egg_info:

except ImportError, excp:
^
SyntaxError: invalid syntax

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in
/tmp/pip-build-5bflk4zs/pydot/

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
