I don’t understand the big deal about state of the art result. If you know the algorithm (from paper) and the high level tool is available (pytorch) then it is not difficult. If you find it difficult then you are not a good enough software developer and you are not able to produce anything substantial. With fast ai you would mostly end up burning energy in gpu and waste your time. I would better learn c++ then deep learning.
