p3 instance types are not showing up for AWS Deep Learning AMIs

Hello,

I am following the instructions here: https://aws.amazon.com/blogs/machine-learning/get-started-with-deep-learning-using-the-aws-deep-learning-ami/

However, no p3 instances show up in step 3a for me to choose, and I'd like to use those instances (that have GPUs) for training deep models.

I had opened a free AWS account a number of years ago, and am now trying to set it up again for Deep Learning, and I understand that using GPU instances is not free, but I don't even get to choose one to configure it, and I am not sure if something is wrong with my account settings. Please help.

Thanks!
