We’re currently recommending Paperspace as the best option for this course (we’re not affiliated with the company in any way). You can get a $15 credit with the code: FASTAI15 . If you need any help with getting set up on Paperspace, feel free to ask here! The video shows how to set up paperspace from scratch, but that’s no longer necessary - instead, choose the ‘fast.ai’ paperspace template (instead of the ubuntu template) when you create your instance.
With many thanks to @reshama, here are written instructions for setting up Paperspace. (NB: currently these instructions are still showing the old way to setup paperspace from scratch, so ignore that part)
