Hello Lija, thanks for your feedback. Unfortunately the training too much time in all machine learnings. What you can do is download the code locally and run the training for as much as is needed, since I doubt that running it on Google Free Account will be any useful. Another way to accelerate training is to use a powerful VM on the cloud, but this will cost money, unless you are really motivated, I don't think it would be a good idea :).

Regards
