Fast Ai configuration in kaggle

I have set up Fast AI along with py-torch in kaggle. I am having a question of how can speed up the training process any help would be highly appreciated.

This is my work, please find the needful code.

you cannot, because kaggle does not allow GPU to be turned on for custom modules (as fastai 0.7 would be custom caz kaggle now has fastai 1.0)
