text: Title: How can I pass train/test splits to auto ml for classification?
  Body: What to do when we dont have a "column description" and only a vector of labels?
  
  ```
  X_train, X_test, y_train, y_test = train_test_split(X, Y,
                                                      train_size=0.75, test_size=0.25)
  
  ```
