Fastai v0.7 install issues thread

[PegasusWithoutWinds (George Zhang)]

I noted that the setup is slightly different from what Jeremy posted in Wiki thread: lesson 1 for the Machine Learning MOOC:

@jeremy

Setting up your computer if it already has Anaconda installed

git clone https://github.com/fastai/fastai
cd fastai
conda create -n fastai python=3.6 anaconda
conda env update
source activate fastai

Would you mind explain a bit about the difference between these two ways of setting up fast.ai v0.7?
