Change in the order of the tuple for Ubuntu-OS

[Anselmoo]

It looks like that the order of the tuple is a change in the case of Ubuntu OS which will cause an assert error.

  AssertionError: assert ('val', 'train') == ('train', 'val')

Possible workaround:

Instead of a total compare, a partial compare like:

 assert 'train' in ['train', 'val']
 assert 'val' in ['train', 'val']
