from transformers import PretrainedConfig
class Seq2LabelsConfig(PretrainedConfig):
r"""
This is the configuration class to store the configuration of a [`Seq2LabelsModel`]. It is used to
instantiate a Seq2Labels model according to the specified arguments, defining the model architecture. Instantiating a
configuration with the defaults will yield a similar configuration to that of the Seq2Labels architecture.
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
documentation from [`PretrainedConfig`] for more information.
Args:
vocab_size (`int`, *optional*, defaults to 30522):
Vocabulary size of the BERT model. Defines the number of different tokens that can be represented by the
`inputs_ids` passed when calling [`BertModel`] or [`TFBertModel`].
pretrained_name_or_path (`str`, *optional*, defaults to `bert-base-cased`):
Pretrained BERT-like model path
load_pretrained (`bool`, *optional*, defaults to `False`):
Whether to load pretrained model from `pretrained_name_or_path`
use_cache (`bool`, *optional*, defaults to `True`):
Whether or not the model should return the last key/values attentions (not used by all models). Only
relevant if `config.is_decoder=True`.
predictor_dropout (`float`, *optional*):
The dropout ratio for the classification head.
special_tokens_fix (`bool`, *optional*, defaults to `False`):
Whether to add additional tokens to the BERT's embedding layer.
Examples:
```python
>>> from transformers import BertModel, BertConfig
>>> # Initializing a Seq2Labels style configuration
>>> configuration = Seq2LabelsConfig()
>>> # Initializing a model from the bert-base-uncased style configuration
>>> model = Seq2LabelsModel(configuration)
>>> # Accessing the model configuration
>>> configuration = model.config
```"""
