  while loading without `features` it loads without errors
  
  ```
  sentences = load_dataset("loretoparisi/tatoeba-sentences",
                               data_files=data_files,
                               delimiter='\t', 
                               column_names=['label', 'text']
                           )
  ```
  
  but the `label` col seems to be wrong (without the `ClassLabel` object):
  
  ```
  sentences['train'].features
  {'label': Value(dtype='string', id=None),
   'text': Value(dtype='string', id=None)}
  ```
  
  The dataset was https://huggingface.co/datasets/loretoparisi/tatoeba-sentences
  
  
  Dataset format is:
  
  ```
  ces	Nechci vědět, co je tam uvnitř.
  ces	Kdo o tom chce slyšet?
  deu	Tom sagte, er fühle sich nicht wohl.
  ber	Mel-iyi-d anida-t tura ?
  hun	Gondom lesz rá rögtön.
  ber	Mel-iyi-d anida-tt tura ?
  deu	Ich will dich nicht reden hören.
  ```
  
  ### Expected behavior
  
  ```shell
  correctly load train and test files.
  ```
