+    Constructs a CLVP 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.
+
+    This class extracts log-mel-spectrogram features from raw speech using a custom numpy implementation of the `Short
+    Time Fourier Transform` which should match pytorch's `torch.stft` equivalent.
+
+    Args:
+        feature_size (`int`, *optional*, defaults to 80):
+            The feature dimension of the extracted features.
+        sampling_rate (`int`, *optional*, defaults to 22050):
+            The sampling rate at which the audio files should be digitalized expressed in hertz (Hz).
+        default_audio_length (`int`, *optional*, defaults to 6):
+            The default length of raw audio in seconds. If `max_length` is not set during `__call__` then it will
+            automatically be set to default_audio_length * `self.sampling_rate`.
+        hop_length (`int`, *optional*, defaults to 256):
+            Length of the overlapping windows for the STFT used to obtain the Mel Frequency coefficients.
+        chunk_length (`int`, *optional*, defaults to 30):
+            The maximum number of chunks of `sampling_rate` samples used to trim and pad longer or shorter audio
+            sequences.
+        n_fft (`int`, *optional*, defaults to 1024):
+            Size of the Fourier transform.
+        padding_value (`float`, *optional*, defaults to 0.0):
+            Padding value used to pad the audio. Should correspond to silences.
+        mel_norms (`list` of length `feature_size`, *optional*):
+            If `mel_norms` is provided then it will be used to normalize the log-mel spectrograms along each
+            mel-filter.

+            Whether to return the attention mask. If left to the default, it will return the attention mask.

+
+    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 ClvpTokenizer
+
+    >>> tokenizer = ClvpTokenizer.from_pretrained("susnato/clvp_dev")
+    >>> tokenizer("Hello world")["input_ids"]

+    [2, 62, 84, 28, 2, 179, 79]
+    ```
+
+    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.

+        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 beginning of sequence token that was used during pretraining. Can be used a sequence classifier token.
+        eos_token (`str`, *optional*, defaults to `"</s>"`):
+            The end of sequence token.
+        prefix_token (`str`, *optional*, defaults to `"▁<PRE>"`):

+    Construct a CodeGen 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 CodeGenTokenizer
+
+    >>> tokenizer = CodeGenTokenizer.from_pretrained("Salesforce/codegen-350M-mono")
+    >>> tokenizer("Hello world")["input_ids"]

+
+    >>> tokenizer(" Hello world")["input_ids"]
+    [18435, 995]
+    ```
+
+    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>

+    Construct a Cohere tokenizer. Based on byte-level Byte-Pair-Encoding.
+
+    This uses notably ByteFallback and NFC normalization.
+

+    >>> from transformers import AutoTokenizer
+
+    >>> tokenizer = AutoTokenizer.from_pretrained("CohereForAI/c4ai-command-r-v01")
+    >>> tokenizer.encode("Hello this is a test")

+    ```
+
+    If you want to change the `bos_token` or the `eos_token`, make sure to specify them when initializing the model, or
+    call `tokenizer.update_post_processor()` to make sure that the post-processing is correctly done (otherwise the
+    values of the first token and final token of an encoded sequence will not be correct). For more details, checkout
+    [post-processors] (https://huggingface.co/docs/tokenizers/api/post-processors) documentation.
+
+    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 [`TokenizersBackend`] which contains most of the main methods. Users should
+    refer to this superclass for more information regarding those methods.

+                If set, will return tensors of a particular framework. Has no effect if tokenize is `False`. Acceptable

+    Constructs a CohereAsr 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.
+
+    This class extracts mel-filter bank features from raw speech using a custom numpy implementation of the `Short Time
+    Fourier Transform` which should match pytorch's `torch.stft` equivalent.
+
+    Args:
+        feature_size (`int`, *optional*, defaults to 128):
+            The feature dimension of the extracted features.
+        sampling_rate (`int`, *optional*, defaults to 16000):
+            The sampling rate at which the audio files should be digitalized expressed in hertz (Hz).
+        hop_length (`int`, *optional*, defaults to 160):
+            Length of the overlapping windows for the STFT used to obtain the Mel Frequency coefficients.
+        n_fft (`int`, *optional*, defaults to 512):
+            Size of the Fourier transform.
+        win_length (`int`, *optional*, defaults to 400):
+            The window length for the STFT computation.
+        preemphasis (`float`, *optional*, defaults to 0.97):
+            A preemphasis filter coefficient. 0.0 means no preemphasis filter.
+        padding_value (`float`, *optional*, defaults to 0.0):
+            Padding value used to pad the audio. Should correspond to silences.
+        dither (`float`, *optional*, defaults to 1e-05):
+            Amount of deterministic dither noise to add before feature extraction. Each sample is seeded by its
+            valid waveform length so that dither is batch-composition invariant. Set to 0.0 to disable.
+        max_audio_clip_s (`float`, *optional*, defaults to 35.0):
+            Maximum duration in seconds for a single audio chunk. Audio longer than
+            `max_audio_clip_s - overlap_chunk_second` is split at energy-based boundaries.
+        overlap_chunk_second (`float`, *optional*, defaults to 5.0):
+            Size in seconds of the boundary search window used when splitting long audio. This is not actual
+            overlap between chunks — it defines how far back from the chunk boundary to search for a quiet
+            split point.
+        min_energy_window_samples (`int`, *optional*, defaults to 1600):
+            Size in samples of the sliding window used to find the quietest point when splitting audio chunks.

+        Main method to featurize and prepare for the model one or several sequence(s). Implementation uses PyTorch for
+        the STFT computation if available, otherwise a slower NumPy based one.
+
+        Args:
+            raw_speech (`np.ndarray`, `list[float]`, `list[np.ndarray]`, `list[list[float]]`):
+                The sequence or batch of sequences to be padded. Each sequence can be a numpy array, a list of float
+                values, a list of numpy arrays or a list of list of float values. Must be mono channel audio, not
+                stereo, i.e. single float per timestep.
+            truncation (`bool`, *optional*, default to `True`):
+                Activates truncation to cut input sequences longer than *max_length* to *max_length*.
+            pad_to_multiple_of (`int`, *optional*, defaults to None):
+                If set will pad the sequence to a multiple of the provided value.
+
+                This is especially useful to enable the use of Tensor Cores on NVIDIA hardware with compute capability
+                `>= 7.5` (Volta), or on TPUs which benefit from having sequence lengths be a multiple of 128.
+            return_attention_mask (`bool`, *optional*):
+                Whether to return the attention mask. If left to the default, will return the attention mask according
+                to the specific feature_extractor's default.
+
+                [What are attention masks?](../glossary#attention-mask)
+
+                <Tip>
+
+                For CohereAsr models, `attention_mask` should always be passed for batched inference, to avoid subtle
+                bugs.
+
+                </Tip>
+
+            return_tensors (`str` or [`~utils.TensorType`], *optional*):
+                If set, will return tensors instead of list of python integers. Acceptable values are:
+
+                - `'tf'`: Return TensorFlow `tf.constant` objects.
+                - `'pt'`: Return PyTorch `torch.Tensor` objects.
+                - `'np'`: Return Numpy `np.ndarray` objects.
+            sampling_rate (`int`, *optional*):
+                The sampling rate at which the `raw_speech` input was sampled. It is strongly recommended to pass
+                `sampling_rate` at the forward call to prevent silent errors and allow automatic speech recognition
+                pipeline.
+            padding_value (`float`, *optional*, defaults to 0.0):
+                The value that is used to fill the padding values / vectors.
+            do_normalize (`bool`, *optional*, defaults to `False`):
+                Whether or not to zero-mean unit-variance normalize the input. Normalizing can help to significantly
+                improve the performance of the model.
+            device (`str`, *optional*, defaults to `'cpu'`):
+                Specifies the device for computation of the log-mel spectrogram of audio signals in the
+                `_torch_extract_fbank_features` method. (e.g., "cpu", "cuda")
+            return_token_timestamps (`bool`, *optional*, defaults to `None`):
+                Deprecated. Use `return_attention_mask` instead from which the number of frames can be inferred.
+
+                Whether or not to return the number of frames of the input raw_speech.
+                These num_frames can be used by the model to compute word level timestamps.

+    Following the ColPali approach, ColModernVBert leverages VLMs to construct efficient multi-vector embeddings directly

+    introduced in ColBERT.

+

+    Following the ColPali approach, ColModernVBert leverages VLMs to construct efficient multi-vector embeddings directly

+    introduced in ColBERT.

+    Following the ColPali approach, ColQwen2 leverages VLMs to construct efficient multi-vector embeddings directly
+    from document images (“screenshots”) for document retrieval. The model is trained to maximize the similarity
+    between these document embeddings and the corresponding query embeddings, using the late interaction method
+    introduced in ColBERT.
+
+    Using ColQwen2 removes the need for potentially complex and brittle layout recognition and OCR pipelines with
+    a single model that can take into account both the textual and visual content (layout, charts, ...) of a document.
+
+    ColQwen2 is part of the ColVision model family, which was introduced with ColPali in the following paper:

+    Following the ColPali approach, ColQwen2 leverages VLMs to construct efficient multi-vector embeddings directly

+    introduced in ColBERT.

+    ColQwen2 is part of the ColVision model family, which was introduced with ColPali in the following paper:
