Their notebooks are indeed the best I ever used : so good that I use them for the interface and not the compute power.

I don't need more compute power or longer instances as I use collab with my own hardware (I have a good enough GPU and I don't risk being disconnected), what I need is the ability to run it fully locally with my python environement (+libs) and local data that never leaves my computer (making it effectively and alternative interface for python jupyter notebooks).
