ULMFiT paper code

I know the ULMFiT is based on fastai library, and I have watched the DL Part 1 videos. However, what I am looking for is the code that was used for ULMFiT paper. I like to see how all the different pieces they have fit together in a pipeline (differential LR, batch norm, drop out, etc.) I have done some Google search but didn’t have much luck.
