AutoClasses
-----------

In many cases, the architecture you want to use can be guessed from the name or the path of the pretrained model you
are supplying to the :obj:`from_pretrained()` method.
AutoClasses are here to do this job for you so that you automatically retrieve the relevant model given the name/path
to the pretrained weights/config/vocabulary.

Instantiating one of :class:`~transformers.AutoConfig`, :class:`~transformers.AutoModel`, and
:class:`~transformers.AutoTokenizer` will directly create a class of the relevant architecture. For instance


.. code-block:: python

    model = AutoModel.from_pretrained('bert-base-cased')

will create a model that is an instance of :class:`~transformers.BertModel`.

There is one class of :obj:`AutoModel` for each task, and for each backend (PyTorch or TensorFlow).
