Training installation instructions vs Ubuntu 14.04.5

[hoehrmann]

Hi. Following https://github.com/jcjohnson/fast-neural-style/blob/master/doc/training.md on a Ubuntu 14.04.5 system, I noticed a few things.

• missing sudo apt-get install python-virtualenv step
• the pip install -r requirements.txt step ran against some UnicodeDecodeError: 'ascii' codec can't decode ... issue; re-starting with LC_ALL=C LANG=C helped (ordinarily set to en_GB.utf8)
• apparently installing numpy through the requirements.txt is unreliable, google search suggests that other projects have similar problems; installing it beforehand in the virtual environment with pip install numpy helped.
