While "import utils; reload(utils) from utils import plots" has this error: AttributeError: 'unicode' object has no attribute 'version'

Hi all,

I have run the model no problem on my own AWS machine on dogs_cats_redux.ipynb, so I set up an aws-ami (my office AWS machine) to run the model on our own images and keep have this error.

Any insight and help from you would be highly appreciated

if any of you see a similar error like mine, it causes by 'import bcolz’
I solved this problem by reinstalling bcolz from github by ''pip install git+https://github.com/Blosc/bcolz.git"
