There may be some technical reasons behind this but I don't think this should be exposed to the users.
These Views are just a container as far as I can see. So, I wonder if having something like:
```python
class Train:
"""The training set"""
def __init__(self, parameters=None, root_folder=None):
self.parameters = parameters
self.root_folder = root_folder
# initialize the db interface here
# e.g. load a csv file
import pandas as pd
self.df = pd.read_csv(...)
def __len__(self):
# return the total number of items in here
return len(self.df)
def __getitem__(self, index):
# return the nth row in here
row = self.df.iloc[index]
# load the data here if necessary
row.image = load(row.filename)
return row
```
would not satisfy the requirements.Interactivity and Intuitive API
