-----------------------------------------------------------------------------------------------------------------------
|
|
|
|
The base classes :class:`~transformers.PreTrainedModel` and :class:`~transformers.TFPreTrainedModel` implement the
|
|
common methods for loading/saving a model either from a local file or directory, or from a pretrained model
|
|
configuration provided by the library (downloaded from HuggingFace's AWS S3 repository).
|
|
|
|
:class:`~transformers.PreTrainedModel` and :class:`~transformers.TFPreTrainedModel` also implement a few methods which
|
|
are common among all the models to:
|
|
|
|
- resize the input token embeddings when new tokens are added to the vocabulary
|
|
- prune the attention heads of the model.
|
|
|
|
The other methods that are common to each model are defined in :class:`~transformers.modeling_utils.ModuleUtilsMixin`
|
|
(for the PyTorch models) and :class:`~transformers.modeling_tf_utils.TFModuleUtilsMixin` (for the TensorFlow models) or
|
|
for text generation, :class:`~transformers.generation_utils.GenerationMixin` (for the PyTorch models) and
|
|
:class:`~transformers.generation_tf_utils.TFGenerationMixin` (for the TensorFlow models)
