I am on How do I get started? of the Fast ai course. A Paperspace account is not available to me - refusing to verify my phone number. It seems like I used all my attempts to create an account there, what are the other best cloud alternatives Paperspace Gradient ( can also be paid), what are the other free cloud alternatives people are using? Also, if you can share some resources to get started with those free cloud alternatives, that will be a great help!
Thanks!
