No such file or directory: 'data/from.map'

See the traceback below. This doesn't work on Ubuntu 14.04 (AWS GPU instance) running Python 2.7.6.

I ran into the same issue with Python 2.7.9 on Debian Jessie. I have no clue what is that 'data/from.map' file which must exist there.

@cigrainger It looks like you need to create "data" directory and create two empty files:

• from_to.mat
• inverse_degrees.mat
