False or 'do_not_truncate' to not truncate the sequences. As we have seen before, this is the
    default behavior.
max_length to control the length of the padding/truncation. It can be an integer or None, in which case
  it will default to the maximum length the model can accept. If the model has no specific maximum input length,
  truncation/padding to max_length is deactivated.
Here is a table summarizing the recommend way to setup padding and truncation. If you use pair of inputs sequence in
any of the following examples, you can replace truncation=True by a STRATEGY selected in
['only_first', 'only_second', 'longest_first'], i.e. truncation='only_second' or truncation= 'longest_first' to control how both sequence in the pair are truncated as detailed before.
