   @jeremiedb :
   Thank you. This is a master code! However, do you mind if I point to a 
somewhat strange thing: in your prediction analysis, the predicted timeseries 
is very much just a lagged version of the real timeseries. It may be due to 
insufficient training, but in general this is indicative of either the data 
problem or model problem. So the model learned to copy last observed value as a 
prediction, which is very a poor quality. What do you say, something wrong with 
model or not?
