I had already setup a GPU in Oregon, but realised where the latency was high, so I decided to go for the Ireland solution. As I recall the referenced AMI in the GitHub script for Ireland did not refer to the proper AMI, I searched in the public AMI repository in Ireland for the correct AMI, and fixed that. At that point I realised that the script for Oregon and Irland was different, so i decided to take a copy of the Oregon script, and make the changes necessary for it to work in Irland. The next thing was that the script tried to overwrite my local pem-file for the Oregon setup, so i decided to change the name of the local pem-file to something different. All in all and now have both a working GPU in Oregon and in Irland.
Thank you for making the deep learning course available to the rest of the world, and I am looking forward to take the lessons in the new year.
