class {{cookiecutter.camelcase_modelname}}Config(PretrainedConfig):
    r"""
    This is the configuration class to store the configuration of a :class:`~transformers.{{cookiecutter.camelcase_modelname}}Model`.
    It is used to instantiate an {{cookiecutter.modelname}} 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 {{cookiecutter.modelname}} `{{cookiecutter.checkpoint_identifier}} <https://huggingface.co/{{cookiecutter.checkpoint_identifier}}>`__ architecture.

    Configuration objects inherit from  :class:`~transformers.PretrainedConfig` and can be used
    to control the model outputs. Read the documentation from  :class:`~transformers.PretrainedConfig`
    for more information.


    Args:
        vocab_size (:obj:`int`, `optional`, defaults to 30522):
            Vocabulary size of the {{cookiecutter.modelname}} model. Defines the number of different tokens that can be represented by the
            :obj:`inputs_ids` passed when calling :class:`~transformers.{{cookiecutter.camelcase_modelname}}Model` or
            :class:`~transformers.TF{{cookiecutter.camelcase_modelname}}Model`.
            Vocabulary size of the  model. Defines the different tokens that
            can be represented by the `inputs_ids` passed to the forward method of :class:`~transformers.{{cookiecutter.camelcase_modelname}}Model`.
        hidden_size (:obj:`int`, `optional`, defaults to 768):
            Dimensionality of the encoder layers and the pooler layer.
        num_hidden_layers (:obj:`int`, `optional`, defaults to 12):
            Number of hidden layers in the Transformer encoder.
        num_attention_heads (:obj:`int`, `optional`, defaults to 12):
            Number of attention heads for each attention layer in the Transformer encoder.
        intermediate_size (:obj:`int`, `optional`, defaults to 3072):
            Dimensionality of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
        hidden_act (:obj:`str` or :obj:`function`, `optional`, defaults to :obj:`"gelu"`):
            The non-linear activation function (function or string) in the encoder and pooler.
            If string, :obj:`"gelu"`, :obj:`"relu"`, :obj:`"selu"` and :obj:`"gelu_new"` are supported.
        hidden_dropout_prob (:obj:`float`, `optional`, defaults to 0.1):
            The dropout probabilitiy for all fully connected layers in the embeddings, encoder, and pooler.
        attention_probs_dropout_prob (:obj:`float`, `optional`, defaults to 0.1):
            The dropout ratio for the attention probabilities.
        max_position_embeddings (:obj:`int`, `optional`, defaults to 512):
            The maximum sequence length that this model might ever be used with.
            Typically set this to something large just in case (e.g., 512 or 1024 or 2048).
        type_vocab_size (:obj:`int`, `optional`, defaults to 2):
            The vocabulary size of the :obj:`token_type_ids` passed when calling :class:`~transformers.{{cookiecutter.camelcase_modelname}}Model` or
            :class:`~transformers.TF{{cookiecutter.camelcase_modelname}}Model`.
        initializer_range (:obj:`float`, `optional`, defaults to 0.02):
            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
        layer_norm_eps (:obj:`float`, `optional`, defaults to 1e-12):
            The epsilon used by the layer normalization layers.

    Example::

        >>> from transformers import {{cookiecutter.camelcase_modelname}}Model, {{cookiecutter.camelcase_modelname}}Config

        >>> # Initializing a {{cookiecutter.modelname}} {{cookiecutter.checkpoint_identifier}} style configuration
        >>> configuration = {{cookiecutter.camelcase_modelname}}Config()

        >>> # Initializing a model from the {{cookiecutter.checkpoint_identifier}} style configuration
        >>> model = {{cookiecutter.camelcase_modelname}}Model(configuration)

        >>> # Accessing the model configuration
        >>> configuration = model.config
