class BlipTextConfig(PretrainedConfig):
    r"""
    This is the configuration class to store the configuration of a [`BlipTextModel`]. It is used to instantiate a BLIP
    text 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 `BlipText` used by the [base
    architectures](https://huggingface.co/Salesforce/blip-vqa-base).

    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 `Blip` text model. Defines the number of different tokens that can be represented by
            the `inputs_ids` passed when calling [`BlipModel`].
        hidden_size (`int`, *optional*, defaults to 768):
            Dimensionality of the encoder layers and the pooler layer.
        encoder_hidden_size (`int`, *optional*, defaults to 768):
            Dimensionality of the encoder layers from the vision model.
        intermediate_size (`int`, *optional*, defaults to 3072):

        max_position_embeddings (`int`, *optional*, defaults to 77):
            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).
        hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
            `"relu"`, `"selu"` and `"gelu_new"` ``"gelu"` are supported.
        layer_norm_eps (`float`, *optional*, defaults to 1e-12):
            The epsilon used by the layer normalization layers.
        hidden_dropout_prob (`float`, *optional*, defaults to 0.0):
            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
        attention_dropout (`float`, *optional*, defaults to 0.0):
            The dropout ratio for the attention probabilities.
        initializer_range (`float`, *optional*, defaults to 0.02):
            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
        bos_token_id (`int`, *optional*, defaults to 30522):
            The id of the `beginning-of-sequence` token.
        eos_token_id (`int`, *optional*, defaults to 2):
            The id of the `end-of-sequence` token.
        pad_token_id (`int`, *optional*, defaults to 0):
            The id of the `padding` token.
        sep_token_id (`int`, *optional*, defaults to 102):
            The id of the `separator` token.
        is_decoder (`bool`, *optional*, defaults to `False`):
            Whether the model is used as a decoder.
        use_cache (`bool`, *optional*, defaults to `True`):
            Whether or not the model should return the last key/values attentions (not used by all models).
