Confusion on python version for AWS

Edit: Nevermind, I got paperspace back up and running so I don’t need to worry about AWS issue anymore

Hi, I heard on the first video that I should be using Python 3, however, after completing the AWS setup instructions (because I’ve already waited a week now for paperspace to approve a GPU), the anaconda python install is Python 2.7.15 :: Anaconda custom (64-bit). When inside the fastai conda env it seems Python 3.6.5 is aliased as python, so I still figured I should just use python 3 as per the video instructions. But then I found out that torch.cuda.is_available() is only returning True for anaconda python 2.7.

So my question is, should I be using Python 3 and somehow figure out how to get it to return true for torch.cuda.is_available(), or remove the alias and use python 2 which is the default anaconda and already seems to be set up correctly?
