+    r"""
+    This is the configuration class to store the configuration of a [`BigBirdModel`]. It is used to instantiate an
+    BigBird 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 BigBird
+    [google/bigbird-roberta-base](https://huggingface.co/google/bigbird-roberta-base) 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 50358):
+            Vocabulary size of the BigBird model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`BigBirdModel`].
+        hidden_size (`int`, *optional*, defaults to 768):
+            Dimension of the encoder layers and the pooler layer.
+        num_hidden_layers (`int`, *optional*, defaults to 12):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 12):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        intermediate_size (`int`, *optional*, defaults to 3072):
+            Dimension of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
+        hidden_act (`str` or `function`, *optional*, defaults to `"gelu_new"`):
+            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 0.1):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout ratio for the attention probabilities.
+        max_position_embeddings (`int`, *optional*, defaults to 4096):
+            The maximum sequence length that this model might ever be used with. Typically set this to something large
+            just in case (e.g., 1024 or 2048 or 4096).
+        type_vocab_size (`int`, *optional*, defaults to 2):
+            The vocabulary size of the `token_type_ids` passed when calling [`BigBirdModel`].
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-12):
+            The epsilon used by the layer normalization layers.
+        is_decoder (`bool`, *optional*, defaults to `False`):
+            Whether the model is used as a decoder or not. If `False`, the model is used as an encoder.
+        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`.
+        attention_type (`str`, *optional*, defaults to `"block_sparse"`)
+            Whether to use block sparse attention (with n complexity) as introduced in paper or original attention
+            layer (with n^2 complexity). Possible values are `"original_full"` and `"block_sparse"`.
+        use_bias (`bool`, *optional*, defaults to `True`)
+            Whether to use bias in query, key, value.
+        rescale_embeddings (`bool`, *optional*, defaults to `False`)
+            Whether to rescale embeddings with (hidden_size ** 0.5).
+        block_size (`int`, *optional*, defaults to 64)
+            Size of each block. Useful only when `attention_type == "block_sparse"`.
+        num_random_blocks (`int`, *optional*, defaults to 3)
+            Each query is going to attend these many number of random blocks. Useful only when `attention_type ==
+            "block_sparse"`.
+        classifier_dropout (`float`, *optional*):
+            The dropout ratio for the classification head.
+

+    Construct a BigBird tokenizer. Based on [SentencePiece](https://github.com/google/sentencepiece).
+
+    This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to
+    this superclass for more information regarding those methods.
+
+    Args:
+        vocab_file (`str`):
+            [SentencePiece](https://github.com/google/sentencepiece) file (generally has a *.spm* extension) that
+            contains the vocabulary necessary to instantiate a tokenizer.
+        unk_token (`str`, *optional*, defaults to `"<unk>"`):
+            The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this
+            token instead.
+        bos_token (`str`, *optional*, defaults to `"<s>"`):
+            The begin of sequence token.
+        eos_token (`str`, *optional*, defaults to `"</s>"`):
+            The end of sequence token.
+        pad_token (`str`, *optional*, defaults to `"<pad>"`):
+            The token used for padding, for example when batching sequences of different lengths.
+        sep_token (`str`, *optional*, defaults to `"[SEP]"`):
+            The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for
+            sequence classification or for a text and a question for question answering. It is also used as the last
+            token of a sequence built with special tokens.
+        mask_token (`str`, *optional*, defaults to `"[MASK]"`):
+            The token used for masking values. This is the token used when training this model with masked language
+            modeling. This is the token which the model will try to predict.
+        cls_token (`str`, *optional*, defaults to `"[CLS]"`):
+            The classifier token which is used when doing sequence classification (classification of the whole sequence
+            instead of per-token classification). It is the first token of the sequence when built with special tokens.
+        sp_model_kwargs (`dict`, *optional*):
+            Will be passed to the `SentencePieceProcessor.__init__()` method. The [Python wrapper for
+            SentencePiece](https://github.com/google/sentencepiece/tree/master/python) can be used, among other things,
+            to set:
+
+            - `enable_sampling`: Enable subword regularization.
+            - `nbest_size`: Sampling parameters for unigram. Invalid for BPE-Dropout.
+
+              - `nbest_size = {0,1}`: No sampling is performed.
+              - `nbest_size > 1`: samples from the nbest_size results.
+              - `nbest_size < 0`: assuming that nbest_size is infinite and samples from the all hypothesis (lattice)
+                using forward-filtering-and-backward-sampling algorithm.
+
+            - `alpha`: Smoothing parameter for unigram sampling, and dropout probability of merge operations for
+              BPE-dropout.

+class MobileNetV2Config(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`MobileNetV2Model`]. It is used to instantiate a
+    MobileNetV2 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 MobileNetV2
+    [google/mobilenet_v2_1.0_224](https://huggingface.co/google/mobilenet_v2_1.0_224) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        num_channels (`int`, *optional*, defaults to 3):
+            The number of input channels.
+        image_size (`int`, *optional*, defaults to 224):
+            The size (resolution) of each image.
+        depth_multiplier (`float`, *optional*, defaults to 1.0):
+            Shrinks or expands the number of channels in each layer. Default is 1.0, which starts the network with 32
+            channels. This is sometimes also called "alpha" or "width multiplier".
+        depth_divisible_by (`int`, *optional*, defaults to 8):
+            The number of channels in each layer will always be a multiple of this number.
+        min_depth (`int`, *optional*, defaults to 8):
+            All layers will have at least this many channels.
+        expand_ratio (`float`, *optional*, defaults to 6.0):
+            The number of output channels of the first layer in each block is input channels times expansion ratio.
+        output_stride (`int`, *optional*, defaults to 32):
+            The ratio between the spatial resolution of the input and output feature maps. By default the model reduces
+            the input dimensions by a factor of 32. If `output_stride` is 8 or 16, the model uses dilated convolutions
+            on the depthwise layers instead of regular convolutions, so that the feature maps never become more than 8x
+            or 16x smaller than the input image.
+        first_layer_is_expansion (`bool`, *optional*, defaults to `True`):
+            True if the very first convolution layer is also the expansion layer for the first expansion block.
+        finegrained_output (`bool`, *optional*, defaults to `True`):
+            If true, the number of output channels in the final convolution layer will stay large (1280) even if
+            `depth_multiplier` is less than 1.
+        hidden_act (`str` or `function`, *optional*, defaults to `"relu6"`):
+            The non-linear activation function (function or string) in the Transformer encoder and convolution layers.
+        tf_padding (`bool`, *optional*, defaults to `True`):
+            Whether to use TensorFlow padding rules on the convolution layers.
+        classifier_dropout_prob (`float`, *optional*, defaults to 0.8):
+            The dropout ratio for attached classifiers.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 0.001):
+            The epsilon used by the layer normalization layers.
+        semantic_loss_ignore_index (`int`, *optional*, defaults to 255):
+            The index that is ignored by the loss function of the semantic segmentation model.
+
+    Example:
+
+    ```python
+    >>> from transformers import MobileNetV2Config, MobileNetV2Model
+
+    >>> # Initializing a "mobilenet_v2_1.0_224" style configuration
+    >>> configuration = MobileNetV2Config()
+
+    >>> # Initializing a model from the "mobilenet_v2_1.0_224" style configuration
+    >>> model = MobileNetV2Model(configuration)

+class QDQBertConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`QDQBertModel`]. It is used to instantiate an
+    QDQBERT 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 BERT
+    [google-bert/bert-base-uncased](https://huggingface.co/google-bert/bert-base-uncased) 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 QDQBERT model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`QDQBertModel`].
+        hidden_size (`int`, *optional*, defaults to 768):
+            Dimension of the encoder layers and the pooler layer.
+        num_hidden_layers (`int`, *optional*, defaults to 12):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 12):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        intermediate_size (`int`, *optional*, defaults to 3072):
+            Dimension 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 0.1):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout ratio for the attention probabilities.
+        max_position_embeddings (`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 (`int`, *optional*, defaults to 2):
+            The vocabulary size of the `token_type_ids` passed when calling [`QDQBertModel`].
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-12):
+            The epsilon used by the layer normalization layers.
+        is_decoder (`bool`, *optional*, defaults to `False`):
+            Whether the model is used as a decoder or not. If `False`, the model is used as an encoder.
+        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`.
+
+    Examples:
+
+    ```python
+    >>> from transformers import QDQBertModel, QDQBertConfig
+
+    >>> # Initializing a QDQBERT google-bert/bert-base-uncased style configuration
+    >>> configuration = QDQBertConfig()
