text: Title: What is the best way to get the predicted values of the training set in Darts?
  Body: I am trying to get the **predicted values of my training set** in Darts. In SKlearn, one can simply do:
  ```
  model.fit(training_set)
  model.predict(training_set)
  ```
  
  What is the equivalent method in Darts assuming I have target lags, past covariate lags and future covariate lags?
  
  From what I've tried, the .predict() method is only forward looking after you fit your data so I won't be able to get the predictions of my training set.
  
  Thanks in advance.
