BeitConfiga  
    This is the configuration class to store the configuration of a [`BeitModel`]. It is used to instantiate an BEiT
    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 BEiT
    [microsoft/beit-base-patch16-224-pt22k](https://huggingface.co/microsoft/beit-base-patch16-224-pt22k) architecture.

    Args:
        vocab_size (`int`, *optional*, defaults to 8192):

        intermediate_size (`int`, *optional*, defaults to 3072):
            Dimensionality of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
        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"` are supported.
        hidden_dropout_prob (`float`, *optional*, defaults to 0.0):
            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.0):
            The dropout ratio for the attention probabilities.
        initializer_range (`float`, *optional*, defaults to 0.02):

            The epsilon used by the layer normalization layers.
        image_size (`int`, *optional*, defaults to 224):
            The size (resolution) of each image.

        use_relative_position_bias (`bool`, *optional*, defaults to `False`):
            Whether to use T5-style relative position embeddings in the self-attention layers.
        use_shared_relative_position_bias (`bool`, *optional*, defaults to `False`):
            Whether to use the same relative position embeddings across all self-attention layers of the Transformer.
        layer_scale_init_value (`float`, *optional*, defaults to 0.1):
            Scale to use in the self-attention layers. 0.1 for base, 1e-5 for large. Set 0 to disable layer scale.

        use_mean_pooling (`bool`, *optional*, defaults to `True`):
            Whether to mean pool the final hidden states of the patches instead of using the final hidden state of the
            CLS token, before applying the classification head.
        pool_scales (`Tuple[int]`, *optional*, defaults to `[1, 2, 3, 6]`):
            Pooling scales used in Pooling Pyramid Module applied on the last feature map.
        use_auxiliary_head (`bool`, *optional*, defaults to `True`):
            Whether to use an auxiliary head during training.
        auxiliary_loss_weight (`float`, *optional*, defaults to 0.4):

            The index that is ignored by the loss function of the semantic segmentation model.
        out_features (`List[str]`, *optional*):
            If used as backbone, list of features to output. Can be any of `"stem"`, `"stage1"`, `"stage2"`, etc.
            (depending on how many stages the model has). If unset and `out_indices` is set, will default to the
            corresponding stages. If unset and `out_indices` is unset, will default to the last stage. Must be in the
            same order as defined in the `stage_names` attribute.
        out_indices (`List[int]`, *optional*):
            If used as backbone, list of indices of features to output. Can be any of 0, 1, 2, etc. (depending on how
            many stages the model has). If unset and `out_features` is set, will default to the corresponding stages.
            If unset and `out_features` is unset, will default to the last stage. Must be in the

            Whether to reshape the feature maps to 4D tensors of shape `(batch_size, hidden_size, height, width)` in
            case the model is used as backbone. If `False`, the feature maps will be 3D tensors of shape `(batch_size,
            seq_len, hidden_size)`. Only relevant for [`BeitBackbone`].

    Example:

    ```python
    >>> from transformers import BeitConfig, BeitModel

    >>> # Initializing a BEiT beit-base-patch16-224-pt22k style configuration
    >>> configuration = BeitConfig()

    >>> # Initializing a model (with random weights) from the beit-base-patch16-224-pt22k style configuration
    >>> model = BeitModel(configuration)

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