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).
