+    r"""
+    This is the configuration class to store the configuration of a [`UnivNetModel`]. It is used to instantiate a
+    UnivNet vocoder 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 UnivNet
+    [dg845/univnet-dev](https://huggingface.co/dg845/univnet-dev) architecture, which corresponds to the 'c32'
+    architecture in [maum-ai/univnet](https://github.com/maum-ai/univnet/blob/master/config/default_c32.yaml).
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        model_in_channels (`int`, *optional*, defaults to 64):
+            The number of input channels for the UnivNet residual network. This should correspond to
+            `noise_sequence.shape[1]` and the value used in the [`UnivNetFeatureExtractor`] class.
+        model_hidden_channels (`int`, *optional*, defaults to 32):
+            The number of hidden channels of each residual block in the UnivNet residual network.
+        num_mel_bins (`int`, *optional*, defaults to 100):
+            The number of frequency bins in the conditioning log-mel spectrogram. This should correspond to the value
+            used in the [`UnivNetFeatureExtractor`] class.
+        resblock_kernel_sizes (`tuple[int]` or `list[int]`, *optional*, defaults to `[3, 3, 3]`):
+            A tuple of integers defining the kernel sizes of the 1D convolutional layers in the UnivNet residual
+            network. The length of `resblock_kernel_sizes` defines the number of resnet blocks and should match that of
+            `resblock_stride_sizes` and `resblock_dilation_sizes`.
+        resblock_stride_sizes (`tuple[int]` or `list[int]`, *optional*, defaults to `[8, 8, 4]`):
+            A tuple of integers defining the stride sizes of the 1D convolutional layers in the UnivNet residual
+            network. The length of `resblock_stride_sizes` should match that of `resblock_kernel_sizes` and
+            `resblock_dilation_sizes`.
+        resblock_dilation_sizes (`tuple[tuple[int]]` or `list[list[int]]`, *optional*, defaults to `[[1, 3, 9, 27], [1, 3, 9, 27], [1, 3, 9, 27]]`):
+            A nested tuple of integers defining the dilation rates of the dilated 1D convolutional layers in the
+            UnivNet residual network. The length of `resblock_dilation_sizes` should match that of
+            `resblock_kernel_sizes` and `resblock_stride_sizes`. The length of each nested list in
+            `resblock_dilation_sizes` defines the number of convolutional layers per resnet block.
+        kernel_predictor_num_blocks (`int`, *optional*, defaults to 3):
+            The number of residual blocks in the kernel predictor network, which calculates the kernel and bias for
+            each location variable convolution layer in the UnivNet residual network.
+        kernel_predictor_hidden_channels (`int`, *optional*, defaults to 64):
+            The number of hidden channels for each residual block in the kernel predictor network.
+        kernel_predictor_conv_size (`int`, *optional*, defaults to 3):
+            The kernel size of each 1D convolutional layer in the kernel predictor network.
+        kernel_predictor_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout probability for each residual block in the kernel predictor network.
+        initializer_range (`float`, *optional*, defaults to 0.01):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        leaky_relu_slope (`float`, *optional*, defaults to 0.2):
+            The angle of the negative slope used by the leaky ReLU activation.
+
+    Example:
+
+    ```python

+class UnivNetFeatureExtractor(SequenceFeatureExtractor):
+    r"""
+    Constructs a UnivNet feature extractor.
+
+    This class extracts log-mel-filter bank features from raw speech using the short time Fourier Transform (STFT). The
+    STFT implementation follows that of TacoTron 2 and Hifi-GAN.
+
+    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.
+
+    Args:
+        feature_size (`int`, *optional*, defaults to 1):
+            The feature dimension of the extracted features.
+        sampling_rate (`int`, *optional*, defaults to 24000):
+            The sampling rate at which the audio files should be digitalized expressed in hertz (Hz).
+        padding_value (`float`, *optional*, defaults to 0.0):
+            The value to pad with when applying the padding strategy defined by the `padding` argument to
+            [`UnivNetFeatureExtractor.__call__`]. Should correspond to audio silence. The `pad_end` argument to
+            `__call__` will also use this padding value.
+        do_normalize (`bool`, *optional*, defaults to `False`):
+            Whether to perform Tacotron 2 normalization on the input. Normalizing can help to significantly improve the
+            performance for some models.
+        num_mel_bins (`int`, *optional*, defaults to 100):
+            The number of mel-frequency bins in the extracted spectrogram features. This should match
+            `UnivNetModel.config.num_mel_bins`.
+        hop_length (`int`, *optional*, defaults to 256):
+            The direct number of samples between sliding windows. Otherwise referred to as "shift" in many papers. Note
+            that this is different from other audio feature extractors such as [`SpeechT5FeatureExtractor`] which take
+            the `hop_length` in ms.
+        win_length (`int`, *optional*, defaults to 1024):
+            The direct number of samples for each sliding window. Note that this is different from other audio feature
+            extractors such as [`SpeechT5FeatureExtractor`] which take the `win_length` in ms.
+        win_function (`str`, *optional*, defaults to `"hann_window"`):
+            Name for the window function used for windowing, must be accessible via `torch.{win_function}`
+        filter_length (`int`, *optional*, defaults to 1024):
+            The number of FFT components to use. If `None`, this is determined using
+            `transformers.audio_utils.optimal_fft_length`.
+        max_length_s (`int`, *optional*, defaults to 10):
+            The maximum input length of the model in seconds. This is used to pad the audio.
+        fmin (`float`, *optional*, defaults to 0.0):
+            Minimum mel frequency in Hz.
+        fmax (`float`, *optional*):
+            Maximum mel frequency in Hz. If not set, defaults to `sampling_rate / 2`.
+        mel_floor (`float`, *optional*, defaults to 1e-09):
+            Minimum value of mel frequency banks. Note that the way [`UnivNetFeatureExtractor`] uses `mel_floor` is
+            different than in [`transformers.audio_utils.spectrogram`].
+        center (`bool`, *optional*, defaults to `False`):
+            Whether to pad the waveform so that frame `t` is centered around time `t * hop_length`. If `False`, frame
+            `t` will start at time `t * hop_length`.
+        compression_factor (`float`, *optional*, defaults to 1.0):
+            The multiplicative compression factor for dynamic range compression during spectral normalization.
+        compression_clip_val (`float`, *optional*, defaults to 1e-05):
+            The clip value applied to the waveform before applying dynamic range compression during spectral
+            normalization.
+        normalize_min (`float`, *optional*, defaults to -11.512925148010254):
+            The min value used for Tacotron 2-style linear normalization. The default is the original value from the
+            Tacotron 2 implementation.
+        normalize_max (`float`, *optional*, defaults to 2.3143386840820312):
+            The max value used for Tacotron 2-style linear normalization. The default is the original value from the
+            Tacotron 2 implementation.
+        model_in_channels (`int`, *optional*, defaults to 64):
+            The number of input channels to the [`UnivNetModel`] model. This should match
+            `UnivNetModel.config.model_in_channels`.
+        pad_end_length (`int`, *optional*, defaults to 10):
+            If padding the end of each waveform, the number of spectrogram frames worth of samples to append. The
+            number of appended samples will be `pad_end_length * hop_length`.
+        return_attention_mask (`bool`, *optional*, defaults to `True`):
+            Whether or not [`~UnivNetFeatureExtractor.__call__`] should return `attention_mask`.

+            will load the corresponding pretrained weights from the timm or transformers library. If `use_pretrained_backbone`
+            is `False`, this loads the backbone's config and uses that to initialize the backbone with random weights.
+        use_pretrained_backbone (`bool`, *optional*, `False`):
+            Whether to use pretrained weights for the backbone.
+        use_timm_backbone (`bool`, *optional*, `False`):
+            Whether to load `backbone` from the timm library. If `False`, the backbone is loaded from the transformers
+            library.
+        backbone_kwargs (`dict`, *optional*):
+            Keyword arguments to be passed to AutoBackbone when loading from a checkpoint
+            e.g. `{'out_indices': (0, 1, 2, 3)}`. Cannot be specified if `backbone_config` is set.
+        hidden_size (`int`, *optional*, defaults to 512):
+            The number of hidden units in the convolutional layers.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        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):
+            Weight of the cross-entropy loss of the auxiliary head.
+        auxiliary_channels (`int`, *optional*, defaults to 256):
+            Number of channels to use in the auxiliary head.
+        auxiliary_num_convs (`int`, *optional*, defaults to 1):
+            Number of convolutional layers to use in the auxiliary head.
+        auxiliary_concat_input (`bool`, *optional*, defaults to `False`):
+            Whether to concatenate the output of the auxiliary head with the input before the classification layer.
+        loss_ignore_index (`int`, *optional*, defaults to 255):
+            The index that is ignored by the loss function.

+    r"""
+    This is the configuration class to store the configuration of a [`VideoLlavaForConditionalGeneration`]. It is used to instantiate an
+    VideoLlava 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 like LanguageBind/Video-LLaVA-7B-hf.
+
+    e.g. [LanguageBind/Video-LLaVA-7B-hf](https://huggingface.co/LanguageBind/Video-LLaVA-7B-hf)
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        vision_config (`VideoLlavaVisionConfig`, *optional*):
+            Custom vision config or dict. Defaults to `CLIPVisionConfig` if not indicated.
+        text_config (`Union[AutoConfig, dict]`, *optional*):
+            The config object of the text backbone. Can be any of `LlamaConfig` or `MistralConfig`.
+            Defaults to `LlamaConfig` if not indicated.
+        image_token_index (`int`, *optional*, defaults to 32000):
+            The image token index to encode the image prompt.
+        video_token_index (`int`, *optional*, defaults to 32001):
+            The video token index to encode the image prompt.
+        projector_hidden_act (`str`, *optional*, defaults to `"gelu"`):
+            The activation function used by the multimodal projector.
+        vision_feature_select_strategy (`str`, *optional*, defaults to `"default"`):
+            The feature selection strategy used to select the vision feature from the CLIP backbone.
+            Can be either "full" to select all features or "default" to select features without `CLS`.
+        vision_feature_layer (`Union[int, list[int]]`, *optional*, defaults to -2):
+            The index of the layer to select the vision feature. If multiple indices are provided,
+            the vision feature of the corresponding indices will be concatenated to form the
+            vision features.
+        image_seq_length (`int`, *optional*, defaults to 256):
+            Sequence length of one image embedding.
+        video_seq_length (`int`, *optional*, defaults to 2056):
+            Sequence length of one video embedding.
+        multimodal_projector_bias (`bool`, *optional*, defaults to `True`):
+            Whether to use bias in the multimodal projector.

+    r"""
+    This is the configuration class to store the configuration of a [`ViLTModel`]. It is used to instantiate an ViLT
+    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 ViLT
+    [dandelin/vilt-b32-mlm](https://huggingface.co/dandelin/vilt-b32-mlm) 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 text part of the model. Defines the number of different tokens that can be
+            represented by the `inputs_ids` passed when calling [`ViltModel`].
+        type_vocab_size (`int`, *optional*, defaults to 2):
+            The vocabulary size of the `token_type_ids` passed when calling [`ViltModel`]. This is used when encoding
+            text.
+        modality_type_vocab_size (`int`, *optional*, defaults to 2):
+            The vocabulary size of the modalities passed when calling [`ViltModel`]. This is used after concatenating the
+            embeddings of the text and image modalities.
+        max_position_embeddings (`int`, *optional*, defaults to 40):
+            The maximum sequence length that this model might ever be used with.
+        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" (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 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.
+        image_size (`int`, *optional*, defaults to 384):
+            The size (resolution) of each image.
+        patch_size (`int`, *optional*, defaults to 32):
+            The size (resolution) of each patch.
+        num_channels (`int`, *optional*, defaults to 3):
+            The number of input channels.
+        qkv_bias (`bool`, *optional*, defaults to `True`):
+            Whether to add a bias to the queries, keys and values.
+        max_image_length (`int`, *optional*, defaults to -1):
+            The maximum number of patches to take as input for the Transformer encoder. If set to a positive integer,
+            the encoder will sample `max_image_length` patches at maximum. If set to -1, will not be taken into
+            account.
+        num_images (`int`, *optional*, defaults to -1):
+            The number of images to use for natural language visual reasoning. If set to a positive integer, will be
+            used by [`ViltForImagesAndTextClassification`] for defining the classifier head.
+
+    Example:

+    r"""
+    This is the configuration class to store the configuration of a [`VipLlavaForConditionalGeneration`]. It is used to instantiate an
+    VipLlava 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 VipLlava-9B.
+
+    e.g. [ybelkada/vip-llava-7b-hf](https://huggingface.co/ybelkada/vip-llava-7b-hf)
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        vision_config (`VipLlavaVisionConfig`,  *optional*):
+            Custom vision config or dict
+        text_config (`Union[AutoConfig, dict]`, *optional*):
+            The config object of the text backbone. Can be any of `LlamaConfig` or `MistralConfig`.
+        image_token_index (`int`, *optional*, defaults to 32000):
+            The image token index to encode the image prompt.
+        projector_hidden_act (`str`, *optional*, defaults to `"gelu"`):
+            The activation function used by the multimodal projector.
+        projector_layernorm_eps (`float`, *optional*, defaults to 1e-05):
+            The layer norm epsilon of the projector layernorm
+        vision_feature_layers (`Union[int, list[int]]`, *optional*, defaults to `[-2, -5, -8, -11, 6]`):
+            The vision feature layer, or list of layers to select the vision features from.
+        image_seq_length (`int`, *optional*, defaults to 576):
+            Sequence length of one image embedding.
+
+    Example:
+
+    ```python
+    >>> from transformers import VipLlavaForConditionalGeneration, VipLlavaConfig, CLIPVisionConfig, LlamaConfig
+
