title: Predict next 6 month selling with LSTM
body: <p>I read this code and make some small changes to it

  but when I run this code, it just predicts the last 6 months of selling, I change the train and test set but the problem is not solved.
  I am a noob in the time series, I was wondering if you would mind helping me to predict the next 6 months selling and plot it.</p>
  <p>thanks a lot.</p>
