title: Pixel RNN Pytorch Implementation
body: <p>I am trying to implement Pixel RNN in pytorch, but I cannot seem to find any documentation on this. The main parts of Pixel RNN are Row LSTM and BiDiagonal LSTM, so I am looking for some code of these algorithms to better understand what they are doing. Specifically, I am confused as to these algorithms calculate one row and diagonal at once, respectively. Any help would be much appreciated.</p>
