Windows 8 people: just a heads up. I was having trouble setting up AWS using cygwin, almost in tears from the frustration.
(I had the p2.xlarge approved from amazon prior to figuring these steps out)
After 5 hours of reinstalling cygwin and trying many things to make the bash shell see aws, I would suggest using (loosely written for people with some experience with VM’s):
set up Ubuntu on it
type “sudo apt-get install python-pip”, enter
git clone https://github.com/fastai/courses
cd to ~/courses/setup/
then I could follow the install AWS video and everything worked like the video.
Conclusion: this lets you avoid configuring the proxy for jupyter notebook, changing PATH on cygwin, making python work on cygwin, making the right version of python come up on cygwin, etc.
