+"""  BertGeneration model configuration"""
+
+from ...configuration_utils import PretrainedConfig
+
+
+class BertGenerationConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`BertGenerationPreTrainedModel`]. It is used to
+    instantiate a BertGeneration 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 BertGeneration
+    [google/bert_for_seq_generation_L-24_bbc_encoder](https://huggingface.co/google/bert_for_seq_generation_L-24_bbc_encoder)
+    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 BERT model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`BertGeneration`].
+        hidden_size (`int`, *optional*, defaults to 1024):
+            Dimensionality of the encoder layers and the pooler layer.
+        num_hidden_layers (`int`, *optional*, defaults to 24):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 16):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        intermediate_size (`int`, *optional*, defaults to 4096):
+            Dimensionality of the "intermediate" (often called 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"`, `"silu"` 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).
+        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.
+        pad_token_id (`int`, *optional*, defaults to 0):
+            Padding token id.
+        bos_token_id (`int`, *optional*, defaults to 2):
+            Beginning of stream token id.
+        eos_token_id (`int`, *optional*, defaults to 1):
+            End of stream token id.
+        position_embedding_type (`str`, *optional*, defaults to `"absolute"`):
+            Type of position embedding. Choose one of `"absolute"`, `"relative_key"`, `"relative_key_query"`. For
+            positional embeddings use `"absolute"`. For more information on `"relative_key"`, please refer to
+            [Self-Attention with Relative Position Representations (Shaw et al.)](https://arxiv.org/abs/1803.02155).
+            For more information on `"relative_key_query"`, please refer to *Method 4* in [Improve Transformer Models
+            with Better Relative Position Embeddings (Huang et al.)](https://arxiv.org/abs/2009.13658).
+        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 BertGenerationConfig, BertGenerationEncoder
+
+    >>> # Initializing a BertGeneration config
+    >>> configuration = BertGenerationConfig()
+
+    >>> # Initializing a model (with random weights) from the config
+    >>> model = BertGenerationEncoder(configuration)

+    r"""
+    This is the configuration class to store the configuration of a [`DebertaModel`] or a [`TFDebertaModel`]. It is
+    used to instantiate a DeBERTa 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 DeBERTa
+    [microsoft/deberta-base](https://huggingface.co/microsoft/deberta-base) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Arguments:
+        vocab_size (`int`, *optional*, defaults to 30522):
+            Vocabulary size of the DeBERTa model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`DebertaModel`] or [`TFDebertaModel`].
+        hidden_size (`int`, *optional*, defaults to 768):
+            Dimensionality 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):
+            Dimensionality of the "intermediate" (often named feed-forward) layer in the Transformer encoder.
+        hidden_act (`str` or `Callable`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"silu"`, `"gelu"`, `"tanh"`, `"gelu_fast"`, `"mish"`, `"linear"`, `"sigmoid"` 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 [`DebertaModel`] or [`TFDebertaModel`].
+        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.
+        relative_attention (`bool`, *optional*, defaults to `False`):
+            Whether use relative position encoding.
+        max_relative_positions (`int`, *optional*, defaults to 1):
+            The range of relative positions `[-max_position_embeddings, max_position_embeddings]`. Use the same value
+            as `max_position_embeddings`.
+        pad_token_id (`int`, *optional*, defaults to 0):
+            The value used to pad input_ids.
+        position_biased_input (`bool`, *optional*, defaults to `True`):
+            Whether add absolute position embedding to content embedding.
+        pos_att_type (`List[str]`, *optional*):
+            The type of relative position attention, it can be a combination of `["p2c", "c2p"]`, e.g. `["p2c"]`,
+            `["p2c", "c2p"]`.
+        layer_norm_eps (`float`, optional, defaults to 1e-12):
+            The epsilon used by the layer normalization layers.

+    The DeBERTa model was proposed in [DeBERTa: Decoding-enhanced BERT with Disentangled
+    Attention](https://arxiv.org/abs/2006.03654) by Pengcheng He, Xiaodong Liu, Jianfeng Gao, Weizhu Chen. It's build
+    on top of BERT/RoBERTa with two improvements, i.e. disentangled attention and enhanced mask decoder. With those two
+    improvements, it out perform BERT/RoBERTa on a majority of tasks with 80GB pretraining data.
+
+    This model is also a [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it
+    as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and
+    behavior.
+
+    <Tip>
+
+    TensorFlow models and layers in `transformers` accept two formats as input:
+
+    - having all inputs as keyword arguments (like PyTorch models), or
+    - having all inputs as a list, tuple or dict in the first positional argument.
+
+    The reason the second format is supported is that Keras methods prefer this format when passing inputs to models
+    and layers. Because of this support, when using methods like `model.fit()` things should "just work" for you - just
+    pass your inputs and labels in any format that `model.fit()` supports! If, however, you want to use the second
+    format outside of Keras methods like `fit()` and `predict()`, such as when creating your own layers or models with
+    the Keras `Functional` API, there are three possibilities you can use to gather all the input Tensors in the first
+    positional argument:
+
+    - a single Tensor with `input_ids` only and nothing else: `model(input_ids)`
+    - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring:
+    `model([input_ids, attention_mask])` or `model([input_ids, attention_mask, token_type_ids])`
+    - a dictionary with one or several input Tensors associated to the input names given in the docstring:
+    `model({"input_ids": input_ids, "token_type_ids": token_type_ids})`
+
+    Note that when creating models and layers with
+    [subclassing](https://keras.io/guides/making_new_layers_and_models_via_subclassing/) then you don't need to worry
+    about any of this, as you can just pass inputs like you would to any other Python function!
+
+    </Tip>
+
+    Parameters:
+        config ([`DebertaConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

+    Construct a DeBERTa tokenizer. Based on byte-level Byte-Pair-Encoding.
+
+    This tokenizer has been trained to treat spaces like parts of the tokens (a bit like sentencepiece) so a word will
+    be encoded differently whether it is at the beginning of the sentence (without space) or not:
+
+    ```python
+    >>> from transformers import DebertaTokenizer
+
+    >>> tokenizer = DebertaTokenizer.from_pretrained("microsoft/deberta-base")
+    >>> tokenizer("Hello world")["input_ids"]
+    [1, 31414, 232, 2]
+
+    >>> tokenizer(" Hello world")["input_ids"]
+    [1, 20920, 232, 2]
+    ```
+
+    You can get around that behavior by passing `add_prefix_space=True` when instantiating this tokenizer or when you
+    call it on some text, but since the model was not pretrained this way, it might yield a decrease in performance.
+
+    <Tip>
+
+    When used with `is_split_into_words=True`, this tokenizer will add a space before each word (even the first one).
+
+    </Tip>
+
+    This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to
+    this superclass for more information regarding those methods.

+        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.
+        cls_token (`str`, *optional*, defaults to `"[CLS]"`):
+            The classifier token which is used when doing sequence classification (classification of the whole sequence

+        unk_token (`str`, *optional*, defaults to `"[UNK]"`):

+        pad_token (`str`, *optional*, defaults to `"[PAD]"`):
+            The token used for padding, for example when batching sequences of different lengths.
+        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.
+        add_prefix_space (`bool`, *optional*, defaults to `False`):
+            Whether or not to add an initial space to the input. This allows to treat the leading word just as any
+            other word. (Deberta tokenizer detect beginning of words by the preceding space).
+        add_bos_token (`bool`, *optional*, defaults to `False`):

+    Construct a "fast" DeBERTa tokenizer (backed by HuggingFace's *tokenizers* library). Based on byte-level
+    Byte-Pair-Encoding.
+
+    This tokenizer has been trained to treat spaces like parts of the tokens (a bit like sentencepiece) so a word will
+    be encoded differently whether it is at the beginning of the sentence (without space) or not:
+
+    ```python
+    >>> from transformers import DebertaTokenizerFast
+
+    >>> tokenizer = DebertaTokenizerFast.from_pretrained("microsoft/deberta-base")
+    >>> tokenizer("Hello world")["input_ids"]
+    [1, 31414, 232, 2]
+
+    >>> tokenizer(" Hello world")["input_ids"]
+    [1, 20920, 232, 2]
+    ```
+
+    You can get around that behavior by passing `add_prefix_space=True` when instantiating this tokenizer, but since
+    the model was not pretrained this way, it might yield a decrease in performance.
+
+    <Tip>
+
+    When used with `is_split_into_words=True`, this tokenizer needs to be instantiated with `add_prefix_space=True`.
+
+    </Tip>
+
+    This tokenizer inherits from [`PreTrainedTokenizerFast`] which contains most of the main methods. Users should
+    refer to this superclass for more information regarding those methods.

+            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.
+        add_prefix_space (`bool`, *optional*, defaults to `False`):
+            Whether or not to add an initial space to the input. This allows to treat the leading word just as any
+            other word. (Deberta tokenizer detect beginning of words by the preceding space).

+class EncodecConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of an [`EncodecModel`]. It is used to instantiate a
+    Encodec 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
+    [facebook/encodec_24khz](https://huggingface.co/facebook/encodec_24khz) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        target_bandwidths (`List[float]`, *optional*, defaults to `[1.5, 3.0, 6.0, 12.0, 24.0]`):
+            The range of diffent bandwiths the model can encode audio with.
+        sampling_rate (`int`, *optional*, defaults to 24000):
+            The sampling rate at which the audio waveform should be digitalized expressed in hertz (Hz).
+        audio_channels (`int`, *optional*, defaults to 1):
+            Number of channels in the audio data. Either 1 for mono or 2 for stereo.
+        normalize (`bool`, *optional*, defaults to `False`):
+            Whether the audio shall be normalized when passed.
+        chunk_length_s (`float`, *optional*):
+            If defined the audio is pre-processed into chunks of lengths `chunk_length_s` and then encoded.
+        overlap (`float`, *optional*):
+            Defines the overlap between each chunk. It is used to compute the `chunk_stride` using the following
+            formulae : `int((1.0 - self.overlap) * self.chunk_length)`.
+        hidden_size (`int`, *optional*, defaults to 128):
+            Intermediate representation dimension.
+        num_filters (`int`, *optional*, defaults to 32):
+            Number of convolution kernels of first `EncodecConv1d` down sampling layer.
+        num_residual_layers (`int`,  *optional*, defaults to 1):
+            Number of residual layers.
+        upsampling_ratios (`Sequence[int]` , *optional*, defaults to `[8, 5, 4, 2]`):
+            Kernel size and stride ratios. The encoder uses downsampling ratios instead of upsampling ratios, hence it
+            will use the ratios in the reverse order to the ones specified here that must match the decoder order.
+        norm_type (`str`, *optional*, defaults to `"weight_norm"`):
+            Normalization method. Should be in `["weight_norm", "time_group_norm"]`
+        kernel_size (`int`, *optional*, defaults to 7):
+            Kernel size for the initial convolution.
+        last_kernel_size (`int`, *optional*, defaults to 7):
+            Kernel size for the last convolution layer.
+        residual_kernel_size (`int`, *optional*, defaults to 3):
+            Kernel size for the residual layers.
+        dilation_growth_rate (`int`, *optional*, defaults to 2):
+            How much to increase the dilation with each layer.
+        use_causal_conv (`bool`, *optional*, defaults to `True`):
+            Whether to use fully causal convolution.
+        pad_mode (`str`, *optional*, defaults to `"reflect"`):
+            Padding mode for the convolutions.
+        compress (`int`, *optional*, defaults to 2):
+            Reduced dimensionality in residual branches (from Demucs v3).
+        num_lstm_layers (`int`, *optional*, defaults to 2):
+            Number of LSTM layers at the end of the encoder.
+        trim_right_ratio (`float`, *optional*, defaults to 1.0):
+            Ratio for trimming at the right of the transposed convolution under the `use_causal_conv = True` setup. If
+            equal to 1.0, it means that all the trimming is done at the right.
+        codebook_size (`int`, *optional*, defaults to 1024):
+            Number of discret codes that make up VQVAE.
+        codebook_dim (`int`, *optional*):
+            Dimension of the codebook vectors. If not defined, uses `hidden_size`.
+        use_conv_shortcut (`bool`, *optional*, defaults to `True`):
+            Whether to use a convolutional layer as the 'skip' connection in the `EncodecResnetBlock` block. If False,
+            an identity function will be used, giving a generic residual connection.
+
+    Example:
+
+    ```python
+    >>> from transformers import EncodecModel, EncodecConfig
+
+    >>> # Initializing a "facebook/encodec_24khz" style configuration
+    >>> configuration = EncodecConfig()
+
+    >>> # Initializing a model (with random weights) from the "facebook/encodec_24khz" style configuration
+    >>> model = EncodecModel(configuration)
+
+    >>> # Accessing the model configuration
+    >>> configuration = model.config

+    Constructs an EnCodec feature extractor.
+
+    This feature extractor inherits from [`~feature_extraction_sequence_utils.SequenceFeatureExtractor`] which contains
+    most of the main methods. Users should refer to this superclass for more information regarding those methods.
+
+    Instantiating a feature extractor with the defaults will yield a similar configuration to that of the
+    [facebook/encodec_24khz](https://huggingface.co/facebook/encodec_24khz) architecture.
+
+    Args:
+        feature_size (`int`, *optional*, defaults to 1):
+            The feature dimension of the extracted features. Use 1 for mono, 2 for stereo.
+        sampling_rate (`int`, *optional*, defaults to 24000):
+            The sampling rate at which the audio waveform should be digitalized expressed in hertz (Hz).
+        padding_value (`float`, *optional*, defaults to 0.0):
+            The value that is used to fill the padding values.
+        chunk_length_s (`float`, *optional*):
+            If defined the audio is pre-processed into chunks of lengths `chunk_length_s` and then encoded.
+        overlap (`float`, *optional*):
+            Defines the overlap between each chunk. It is used to compute the `chunk_stride` using the following
+            formulae : `int((1.0 - self.overlap) * self.chunk_length)`.

+    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) subclass.
+    Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage
+    and behavior.
+
+    Parameters:
+        config ([`EncodecConfig`]):
+            Model configuration class with all the parameters of the model. Initializing with a config file does not
+            load the weights associated with the model, only the configuration. Check out the

+class GLPNConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`GLPNModel`]. It is used to instantiate an GLPN
+    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 GLPN
+    [vinvino02/glpn-kitti](https://huggingface.co/vinvino02/glpn-kitti) 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.
+        num_encoder_blocks (`int`, *optional*, defaults to 4):
+            The number of encoder blocks (i.e. stages in the Mix Transformer encoder).
+        depths (`List[int]`, *optional*, defaults to `[2, 2, 2, 2]`):
+            The number of layers in each encoder block.
+        sr_ratios (`List[int]`, *optional*, defaults to `[8, 4, 2, 1]`):
+            Sequence reduction ratios in each encoder block.
+        hidden_sizes (`List[int]`, *optional*, defaults to `[32, 64, 160, 256]`):
+            Dimension of each of the encoder blocks.
+        patch_sizes (`List[int]`, *optional*, defaults to `[7, 3, 3, 3]`):
+            Patch size before each encoder block.
+        strides (`List[int]`, *optional*, defaults to `[4, 2, 2, 2]`):
+            Stride before each encoder block.
+        num_attention_heads (`List[int]`, *optional*, defaults to `[1, 2, 5, 8]`):
+            Number of attention heads for each attention layer in each block of the Transformer encoder.
+        mlp_ratios (`List[int]`, *optional*, defaults to `[4, 4, 4, 4]`):
+            Ratio of the size of the hidden layer compared to the size of the input layer of the Mix FFNs in the
+            encoder blocks.
+        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 standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        drop_path_rate (`float`, *optional*, defaults to 0.1):
+            The dropout probability for stochastic depth, used in the blocks of the Transformer encoder.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-06):
+            The epsilon used by the layer normalization layers.
+        decoder_hidden_size (`int`, *optional*, defaults to 64):
+            The dimension of the decoder.
+        max_depth (`int`, *optional*, defaults to 10):
+            The maximum depth of the decoder.
+        head_in_index (`int`, *optional*, defaults to -1):
+            The index of the features to use in the head.
+
+    Example:
+
+    ```python
+    >>> from transformers import GLPNModel, GLPNConfig
+
+    >>> # Initializing a GLPN vinvino02/glpn-kitti style configuration
