 Wikipedia), and then use that model for downstream NLP tasks that we care about
 (like question answering). BERT outperforms previous methods because it is the
 first *unsupervised*, *deeply bidirectional* system for pre-training NLP.

 #### Is there a PyTorch version available?
 
-There is no official PyTorch implementation. If someone creates a line-for-line
