From the instrcutions setting up miniconda environment, package list as follows:
conda install numpy scipy matplotlib scikit-learn ipython-notebook seaborn
However it hasn't installed PIL package. I was having problems while executing "fetch_data.py" and also while running notebook "2.4 Unsupervised Learning - Clustering"
Please add PIL also to the list.
conda install numpy scipy matplotlib scikit-learn ipython-notebook seaborn PIL
