+    Construct a BERT tokenizer (backed by HuggingFace's tokenizers library). Based on WordPiece.
+
+    This tokenizer inherits from [`TokenizersBackend`] which contains most of the main methods. Users should refer to
+    this superclass for more information regarding those methods.
+
+    Args:
+        vocab (`str` or `dict[str, int]`, *optional*):

+        do_lower_case (`bool`, *optional*, defaults to `True`):
+            Whether or not to lowercase the input when tokenizing.
+        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.
+        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.
+        pad_token (`str`, *optional*, defaults to `"[PAD]"`):
+            The token used for padding, for example when batching sequences of different lengths.
+        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.
+        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.
+        tokenize_chinese_chars (`bool`, *optional*, defaults to `True`):
+            Whether or not to tokenize Chinese characters.
+        strip_accents (`bool`, *optional*):
+            Whether or not to strip all accents. If this option is not specified, then it will be determined by the
+            value for `lowercase` (as in the original BERT).

+            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.
+        pad_token (`str`, *optional*, defaults to `"[PAD]"`):
+            The token used for padding, for example when batching sequences of different lengths.

+            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.

+            The token used for masking values. This is the token used when training this model with masked language

+

+Twitter-aware tokenizer, designed to be flexible and easy to adapt to new domains and tasks. The basic logic is this:
+
+1. The tuple regex_strings defines a list of regular expression strings.
+
+2. The regex_strings strings are put, in order, into a compiled regular expression object called word_re.
+
+3. The tokenization is done by word_re.findall(s), where s is the user-supplied string, inside the tokenize() method of
+   the class Tokenizer.
+
+4. When instantiating Tokenizer objects, there is a single option: preserve_case. By default, it is set to True. If it
+   is set to False, then the tokenizer will lowercase everything except for emoticons.

+    Construct a "fast" BigBird tokenizer (backed by HuggingFace's *tokenizers* library). Based on
+    [Unigram](https://huggingface.co/docs/tokenizers/python/latest/components.html?highlight=unigram#models). This
+    tokenizer inherits from [`PreTrainedTokenizerFast`] which contains most of the main methods. Users should refer to
+    this superclass for more information regarding those methods
+
+    Args:
+        vocab (`str`, `dict` or `list`, *optional*):
+            Custom vocabulary dictionary. If not provided, vocabulary is loaded from vocab_file.
+        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.
+
+            <Tip>
+
+            When building a sequence using special tokens, this is not the token that is used for the beginning of
+            sequence. The token used is the `cls_token`.
+
+            </Tip>
+
+        eos_token (`str`, *optional*, defaults to `"</s>"`):
+            The end of sequence token. .. note:: When building a sequence using special tokens, this is not the token
+            that is used for the end of sequence. The token used is the `sep_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.
+        add_prefix_space (`bool`, *optional*, defaults to `True`):
+            Whether or not to add an initial space to the input. This allows to treat the leading word just as any
+            other word.
+        vocab_file (`str`, *optional*):
+            [SentencePiece](https://github.com/google/sentencepiece) file (generally has a *.spm* extension) that
+            contains the vocabulary necessary to instantiate a tokenizer.

+    """
+    Construct a "fast" Blenderbot tokenizer (backed by HuggingFace's *tokenizers* library), derived from the GPT-2
+    tokenizer, using 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 BlenderbotTokenizerFast
+
+    >>> tokenizer = BlenderbotTokenizerFast.from_pretrained("facebook/blenderbot-3B")
+    >>> tokenizer("Hello world")["input_ids"]
+    [6950, 1085, 2]
+
+    >>> tokenizer(" Hello world")["input_ids"]
+    [6950, 1085, 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 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.
+
+    Args:
+        bos_token (`str`, *optional*, defaults to `"<s>"`):
+            The beginning of sequence token that was used during pretraining. Can be used a sequence classifier token.
+
+            <Tip>
+
+            When building a sequence using special tokens, this is not the token that is used for the beginning of
+            sequence. The token used is the `cls_token`.
+
+            </Tip>
+
+        eos_token (`str`, *optional*, defaults to `"</s>"`):
+            The end of sequence token.
+
+            <Tip>
+
+            When building a sequence using special tokens, this is not the token that is used for the end of sequence.
+            The token used is the `sep_token`.
+
+            </Tip>
+
+        sep_token (`str`, *optional*, defaults to `"</s>"`):
+            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 `"<s>"`):
+            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.
+        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.
+        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 `True`):
+            Whether or not to add an initial space to the input. This allows to treat the leading word just as any
+            other word. (Blenderbot tokenizer detect beginning of words by the preceding space).
+        vocab (`str` or `dict[str, int]`, *optional*):
+            Custom vocabulary dictionary. If not provided, vocabulary is loaded from `vocab_file`.
+        merges (`str` or `list[str]`, *optional*):
+            Custom merges list. If not provided, merges are loaded from `merges_file`.

+    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
+    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 ColModernVBert 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.
+
+    ColModernVBert is trained on top of ModernVBert, and was introduced in the following paper:
+    [*ModernVBERT: Towards Smaller Visual Document Retrievers*](https://arxiv.org/abs/2510.01149).
+
+    ColModernVBert is part of the ColVision model family, which was introduced with ColPali in the following paper:

+    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
+    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:

+        </Tip>
+
+        Parameters:
+            inputs_ids (`torch.Tensor` of shape (batch_size, seq_length), *optional*):
+                The sequence used as a prompt for the backbone model.
+            input_values (`torch.Tensor` of shape (batch_size, channels, max_concatenated_audio_length), *optional*):
+                The batched audio input values, where each batch entry contains the concatenation of all audio segments for that entry.
+                These values will be encoded into codebook tokens using the codec model and merged with the text input ids provided in `input_ids`.
+            input_values_cutoffs (`torch.Tensor` of shape (batch_size, max_num_audio), *optional*):
+                Specify the end positions of audio segments within each batch entry, relative to the concatenated audio input.
+                If a batch entry has fewer segments than the maximum, it is padded with -1. For example, in a batch of 2 sequences
+                where the first contains 2 audio segments of length l1, and the second contains 1 audio segment of length l2,
+                the input_values_cutoffs would be: [[l1, 2 * l1], [l2, -1]].
+            generation_config ([`~generation.GenerationConfig`], *optional*):
+                The generation configuration to be used as base parametrization for the generation call. `**kwargs`
+                passed to generate matching the attributes of `generation_config` will override them. If
+                `generation_config` is not provided, the default will be used, which has the following loading
+                priority: 1) from the `generation_config.json` model file, if it exists; 2) from the model
+                configuration. Please note that unspecified parameters will inherit [`~generation.GenerationConfig`]'s
+                default values, whose documentation should be checked to parameterize generation.
+            logits_processor (`LogitsProcessorList`, *optional*):
+                Custom logits processors that complement the default logits processors built from arguments and
+                generation config. If a logit processor is passed that is already created with the arguments or a
+                generation config an error is thrown. This feature is intended for advanced users.
+            stopping_criteria (`StoppingCriteriaList`, *optional*):
+                Custom stopping criteria that complements the default stopping criteria built from arguments and a
+                generation config. If a stopping criteria is passed that is already created with the arguments or a
+                generation config an error is thrown. If your stopping criteria depends on the `scores` input, make
+                sure you pass `return_dict_in_generate=True, output_scores=True` to `generate`. This feature is
+                intended for advanced users.
+            synced_gpus (`bool`, *optional*):
+                Whether to continue running the while loop until max_length. Unless overridden, this flag will be set
+                to `True` if using `FullyShardedDataParallel` or DeepSpeed ZeRO Stage 3 with multiple GPUs to avoid
+                deadlocking if one GPU finishes generating before other GPUs. Otherwise, defaults to `False`.
+            streamer (`BaseStreamer`, *optional*):
+                Streamer object that will be used to stream the generated sequences. Generated tokens are passed
+                through `streamer.put(token_ids)` and the streamer is responsible for any further processing.
+            output_audio (`bool`, *optional*):
+                Whether to return the generated audio.
+            kwargs (`dict[str, Any]`, *optional*):
+                Ad hoc parametrization of `generation_config` and/or additional model-specific kwargs that will be
+                forwarded to the `forward` function of the model. Depth decoder specific kwargs should be prefixed with *depth_decoder_*.
+
+        Return:
+            [`CsmGenerateOutput`] or `torch.LongTensor` or `list[torch.FloatTensor]`: A [`CsmGenerateOutput`]

+            requires `input_values` to be provided so that audio can be encoded in codebook tokens and then merged with the text tokens.
+
+            2. (batch_size, sequence_length, num_codebooks): codebook tokens generated during the autoregressive decoding. Such input is not meant to be used by end users.

+            If a batch entry has fewer segments than the maximum, it is padded with -1. For example, in a batch of 2 sequences
+            where the first contains 2 audio segments of length l1, and the second contains 1 audio segment of length l2,
+            the input_values_cutoffs would be: [[l1, 2 * l1], [l2, -1]].
+        labels (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Labels for computing the masked language modeling loss. Indices should be in `[config.audio_token_id, -100, -101]`.
+            Requires targeted `input_values` to be provided as audio tokens will be inferred from it using the `codec_model`.
+            - `config.audio_token_id` indicates an audio frames (considering sequence length elements as frames)
+            - `-100` will be ignored in the loss computation
+            - `-101` indicates the audio frame will be used only for the backbone model (using the first codebook token as labels)
+
+            Such labels can be prepared using `output_labels=True` when calling [`CsmProcessor`].
+        logits_to_keep (`int` or `torch.Tensor`, *optional*):
+            Kept for compatibility. Does not support another value than:
+            1. `0`, which is equivalent to keeping all logits, used in the training regime
+            2. `1`, which is equivalent to keeping only the last logit, used in the generation regime

+            requires `input_values` to be provided so that audio can be encoded in codebook tokens and then merged with the text tokens.
+
+            2. (batch_size, sequence_length, num_codebooks): codebook tokens generated during the autoregressive decoding. Such input is not meant to be used by end users.

+            If a batch entry has fewer segments than the maximum, it is padded with -1. For example, in a batch of 2 sequences
+            where the first contains 2 audio segments of length l1, and the second contains 1 audio segment of length l2,
+            the input_values_cutoffs would be: [[l1, 2 * l1], [l2, -1]].
+        labels (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Labels for computing the masked language modeling loss. Indices should be in `[config.audio_token_id, -100, -101]`.
+            Requires targeted `input_values` to be provided as audio tokens will be inferred from it using the `codec_model`.
+            - `config.audio_token_id` indicates an audio frames (considering sequence length elements as frames)
+            - `-100` will be ignored in the loss computation
+            - `-101` indicates the audio frame will be used only for the backbone model (using the first codebook token as labels)
+
+            Such labels can be prepared using `output_labels=True` when calling [`CsmProcessor`].
+        logits_to_keep (`int` or `torch.Tensor`, *optional*):
+            Kept for compatibility. Does not support another value than:
+            1. `0`, which is equivalent to keeping all logits, used in the training regime

+    The CTRL Model transformer with a sequence classification head on top (linear layer).
+    [`CTRLForSequenceClassification`] uses the last token in order to do the classification, as other causal models
+    (e.g. GPT-2) do. Since it does classification on the last token, it requires to know the position of the last
+    token. If a `pad_token_id` is defined in the configuration, it finds the last token that is not a padding token in
+    each row. If no `pad_token_id` is defined, it simply takes the last value in each row of the batch. Since it cannot
+    guess the padding tokens when `inputs_embeds` are passed instead of `input_ids`, it does the same (take the last
+    value in each row of the batch).

+    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 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, 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.
+
+    Args:
+        vocab_file (`str`, *optional*):
+            Path to the vocabulary file.
+        merges_file (`str`, *optional*):
+            Path to the merges file.
+        tokenizer_file (`str`, *optional*):
+            The path to a tokenizer file to use instead of the vocab file.
+        errors (`str`, *optional*, defaults to `"replace"`):
+            Paradigm to follow when decoding bytes to UTF-8. See
+            [bytes.decode](https://docs.python.org/3/library/stdtypes.html#bytes.decode) for more information.
+        bos_token (`str`, *optional*, defaults to `"[CLS]"`):
+            The beginning of sequence token.
+        eos_token (`str`, *optional*, defaults to `"[SEP]"`):
+            The end of sequence token.
+        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
+            instead of per-token classification). It is the first token of the sequence when built with special tokens.
+        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.
+        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).

+    Construct a DeBERTa-v2 tokenizer (backed by HuggingFace's *tokenizers* library). Based on Unigram tokenization.
+
+    This tokenizer inherits from [`TokenizersBackend`] which contains most of the main methods. Users should
+    refer to this superclass for more information regarding those methods.
+
+    Args:
+        vocab_file (`str`, *optional*):
+            Path to the vocabulary file (SentencePiece model file). Not used directly but kept for compatibility.
+        vocab (`str`, `dict` or `list`, *optional*):
+            List of tuples (piece, score) for the vocabulary.
+        precompiled_charsmap (`bytes`, *optional*):
+            Precompiled character map for normalization.
+        do_lower_case (`bool`, *optional*, defaults to `False`):
+            Whether or not to lowercase the input when tokenizing.
+        split_by_punct (`bool`, *optional*, defaults to `False`):
+            Whether to split by punctuation.
+        bos_token (`str`, *optional*, defaults to `"[CLS]"`):
+            The beginning of sequence token.
+        eos_token (`str`, *optional*, defaults to `"[SEP]"`):
+            The end of sequence token.
+        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.
+        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.
+        pad_token (`str`, *optional*, defaults to `"[PAD]"`):
+            The token used for padding, for example when batching sequences of different lengths.
+        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.
+        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 `True`):
+            Whether or not to add an initial space to the input. This allows to treat the leading word just as any
+            other word.
+        unk_id (`int`, *optional*, defaults to index of `unk_token` in vocab):
+            The ID of the unknown token in the vocabulary.

+    See Switch Transformer (https://huggingface.co/papers/2101.03961) for more details. This function implements the loss
+    function presented in equations (4) - (6) of the paper. It aims at penalizing cases where the routing between
+    experts is too unbalanced.

+            shape [2, batch_size * sequence_length, num_keys].

+            Number of keys
+        top_k:
+            The number of experts to route per-token, can be also interpreted as the `top-k` routing
+            parameter.

+            The attention_mask used in forward function
+            shape [batch_size X sequence_length] if not None.

+              if provided).
+            - `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum
+              acceptable input length for the model if that argument is not provided.
+            - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different
+              lengths).
+        truncation (`bool`, `str` or [`~tokenization_utils_base.TruncationStrategy`], *optional*, defaults to `False`):
+            Activates and controls truncation. Accepts the following values:
+
+            - `True` or `'longest_first'`: Truncate to a maximum length specified with the argument `max_length` or to
+              the maximum acceptable input length for the model if that argument is not provided. This will truncate
+              token by token, removing a token from the longest sequence in the pair if a pair of sequences (or a batch
+              of pairs) is provided.
+            - `'only_first'`: Truncate to a maximum length specified with the argument `max_length` or to the maximum
+              acceptable input length for the model if that argument is not provided. This will only truncate the first
+              sequence of a pair if a pair of sequences (or a batch of pairs) is provided.
+            - `'only_second'`: Truncate to a maximum length specified with the argument `max_length` or to the maximum
+              acceptable input length for the model if that argument is not provided. This will only truncate the
+              second sequence of a pair if a pair of sequences (or a batch of pairs) is provided.
+            - `False` or `'do_not_truncate'` (default): No truncation (i.e., can output batch with sequence lengths
+              greater than the model maximum admissible input size).
+        max_length (`int`, *optional*):
+                Controls the maximum length to use by one of the truncation/padding parameters.
+
+                If left unset or set to `None`, this will use the predefined model maximum length if a maximum length
+                is required by one of the truncation/padding parameters. If the model has no specific maximum input
+                length (like XLNet) truncation/padding to a maximum length will be deactivated.
+        return_tensors (`str` or [`~utils.TensorType`], *optional*):
+                If set, will return tensors instead of list of python integers. Acceptable values are:
+
+                - `'pt'`: Return PyTorch `torch.Tensor` objects.
+                - `'np'`: Return Numpy `np.ndarray` objects.

+              acceptable input length for the model if that argument is not provided.
+            - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different
+              lengths).
+        truncation (`bool`, `str` or [`~tokenization_utils_base.TruncationStrategy`], *optional*, defaults to `False`):
+            Activates and controls truncation. Accepts the following values:
+
+            - `True` or `'longest_first'`: Truncate to a maximum length specified with the argument `max_length` or to
+              the maximum acceptable input length for the model if that argument is not provided. This will truncate
+              token by token, removing a token from the longest sequence in the pair if a pair of sequences (or a batch
+              of pairs) is provided.
+            - `'only_first'`: Truncate to a maximum length specified with the argument `max_length` or to the maximum
+              acceptable input length for the model if that argument is not provided. This will only truncate the first
+              sequence of a pair if a pair of sequences (or a batch of pairs) is provided.
+            - `'only_second'`: Truncate to a maximum length specified with the argument `max_length` or to the maximum
+              acceptable input length for the model if that argument is not provided. This will only truncate the
+              second sequence of a pair if a pair of sequences (or a batch of pairs) is provided.
+            - `False` or `'do_not_truncate'` (default): No truncation (i.e., can output batch with sequence lengths
+              greater than the model maximum admissible input size).
+        max_length (`int`, *optional*):
+                Controls the maximum length to use by one of the truncation/padding parameters.
+
+                If left unset or set to `None`, this will use the predefined model maximum length if a maximum length
+                is required by one of the truncation/padding parameters. If the model has no specific maximum input
+                length (like XLNet) truncation/padding to a maximum length will be deactivated.
+        return_tensors (`str` or [`~utils.TensorType`], *optional*):
+                If set, will return tensors instead of list of python integers. Acceptable values are:
+
+                - `'pt'`: Return PyTorch `torch.Tensor` objects.
+                - `'np'`: Return Numpy `np.ndarray` objects.
+        return_attention_mask (`bool`, *optional*):
+            Whether or not to return the attention mask. If not set, will return the attention mask according to the
+            specific tokenizer's default, defined by the `return_outputs` attribute.
+
+            [What are attention masks?](../glossary#attention-mask)
+
+    Return:
+        `dict[str, list[list[int]]]`: A dictionary with the following keys:
+

+        - `attention_mask`: List of indices specifying which tokens should be attended to by the model.

+            better results. The points can be obtained by passing a list of list of list to the processor that will
+            create corresponding `torch` tensors of dimension 4. The first dimension is the image batch size, the
+            second dimension is the point batch size (i.e. how many segmentation masks do we want the model to predict
+            per input point), the third dimension is the number of points per segmentation mask (it is possible to pass
+            multiple points for a single mask), and the last dimension is the x (vertical) and y (horizontal)
+            coordinates of the point. If a different number of points is passed either for each image, or for each
+            mask, the processor will create "PAD" points that will correspond to the (0, 0) coordinate, and the
+            computation of the embedding will be skipped for these points using the labels.

+            - `0`: the point is a point that does not contain the object of interest

+            that will generate a `torch` tensor, with each dimension corresponding respectively to the image batch
+            size, the number of boxes per image and the coordinates of the top left and bottom right point of the box.
+            In the order (`x1`, `y1`, `x2`, `y2`):
+
+            - `x1`: the x coordinate of the top left point of the input box

+            SAM model also accepts segmentation masks as input. The mask will be embedded by the prompt encoder to
+            generate a corresponding embedding, that will be fed later on to the mask decoder. These masks needs to be
+            manually fed by the user, and they need to be of shape (`batch_size`, `image_size`, `image_size`).
+        image_embeddings (`torch.FloatTensor` of shape `(batch_size, output_channels, window_size, window_size)`):
+            Image embeddings, this is used by the mask decoder to generate masks and iou scores. For more memory
+            efficient computation, users can first retrieve the image embeddings using the `get_image_embeddings`
+            method, and then feed them to the `forward` method instead of feeding the `pixel_values`.
+        multimask_output (`bool`, *optional*):
+            In the original implementation and paper, the model always outputs 3 masks per image (or per point / per
+            bounding box if relevant). However, it is possible to just output a single mask, that corresponds to the
+            "best" mask, by specifying `multimask_output=False`.
+        attention_similarity (`torch.FloatTensor`, *optional*):
+            Attention similarity tensor, to be provided to the mask decoder for target-guided attention in case the
+            model is used for personalization as introduced in [PerSAM](https://huggingface.co/papers/2305.03048).
+        target_embedding (`torch.FloatTensor`, *optional*):
+            Embedding of the target concept, to be provided to the mask decoder for target-semantic prompting in case
+            the model is used for personalization as introduced in [PerSAM](https://huggingface.co/papers/2305.03048).

+            better results. The points can be obtained by passing a list of list of list to the processor that will
+            create corresponding `torch` tensors of dimension 4. The first dimension is the image batch size, the
+            second dimension is the point batch size (i.e. how many segmentation masks do we want the model to predict
+            per input point), the third dimension is the number of points per segmentation mask (it is possible to pass
+            multiple points for a single mask), and the last dimension is the x (vertical) and y (horizontal)
+            coordinates of the point. If a different number of points is passed either for each image, or for each
+            mask, the processor will create "PAD" points that will correspond to the (0, 0) coordinate, and the
+            computation of the embedding will be skipped for these points using the labels.

+            Input labels for the points, this is used by the prompt encoder to encode the prompt. According to the
+            official implementation, there are 3 types of labels
+
+            - `1`: the point is a point that contains the object of interest
+            - `0`: the point is a point that does not contain the object of interest
+            - `-1`: the point corresponds to the background
+
+            We added the label:
+
+            - `-10`: the point is a padding point, thus should be ignored by the prompt encoder
+
+            The padding labels should be automatically done by the processor.

+            that will generate a `torch` tensor, with each dimension corresponding respectively to the image batch
+            size, the number of boxes per image and the coordinates of the top left and bottom right point of the box.
+            In the order (`x1`, `y1`, `x2`, `y2`):

+            SAM model also accepts segmentation masks as input. The mask will be embedded by the prompt encoder to
+            generate a corresponding embedding, that will be fed later on to the mask decoder. These masks needs to be
+            manually fed by the user, and they need to be of shape (`batch_size`, `image_size`, `image_size`).
+        image_embeddings (`torch.FloatTensor` of shape `(batch_size, output_channels, window_size, window_size)`):
+            Image embeddings, this is used by the mask decoder to generate masks and iou scores. For more memory
+            efficient computation, users can first retrieve the image embeddings using the `get_image_embeddings`
+            method, and then feed them to the `forward` method instead of feeding the `pixel_values`.
+        multimask_output (`bool`, *optional*):
+            In the original implementation and paper, the model always outputs 3 masks per image (or per point / per
+            bounding box if relevant). However, it is possible to just output a single mask, that corresponds to the
+            "best" mask, by specifying `multimask_output=False`.
+        attention_similarity (`torch.FloatTensor`, *optional*):
+            Attention similarity tensor, to be provided to the mask decoder for target-guided attention in case the
+            model is used for personalization as introduced in [PerSAM](https://huggingface.co/papers/2305.03048).

+    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.
+    use_conv_shortcut (`bool`, *optional*, defaults to `True`):

+    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)`.

+            Optionally, instead of passing `decoder_input_ids` you can choose to directly pass an embedded
+            representation. This is useful if you want more control over how to convert `decoder_input_ids` indices

+        Calculate the 3D rope index based on image and video's sizes. The utility expects a `vision + text`
+        sequence and will error out otherwise. For pure text sequence, please rely on model's auto-inferred
+        position ids. In a mixed vision + text sequence, vision tokens use 3D RoPE (temporal, height, width)
+        while text tokens use standard 1D RoPE.
+
+        Example:
+            Temporal patches: 3; Height patches: 2; Width patches: 2
+            Each vision input results in (temporal x height × width) positions. Here: 3 x 2 × 2 = 12 positions total.
+

+            Width IDs alternate per column: `[0, 1, 0, 1, ...]`

+        Calculate the 3D rope index based on image and video's sizes. The utility expects a `vision + text`

+        position ids. In a mixed vision + text sequence, vision tokens use 3D RoPE (temporal, height, width)
+        while text tokens use standard 1D RoPE.

+        More memory-efficient, inference-only version of the forward function. Uses in-place operations, fusion of the
+        addition that happens after this module in the Evoformer, a smidge of recomputation, and a cache of overwritten
+        values to lower peak memory consumption of this module from 5x the size of the input tensor z to 2.5x its size.
+        Useful for inference on extremely long sequences.
+
+        It works as follows. We will make reference to variables used in the default forward implementation below.
+        Naively, triangle multiplication attention requires the manifestation of 5 tensors the size of z: 1) z, the
+        "square" input tensor, 2) a, the first projection of z, 3) b, the second projection of b, 4) g, a z-sized mask,
+        and 5) a z-sized tensor for intermediate computations. For large N, this is prohibitively expensive; for
+        N=4000, for example, z is more than 8GB alone. To avoid this problem, we compute b, g, and all intermediate
+        tensors in small chunks, noting that the chunks required to compute a chunk of the output depend only on the
+        tensor a and corresponding vertical and horizontal chunks of z. This suggests an algorithm that loops over
+        pairs of chunks of z: hereafter "columns" and "rows" of z, even though each "column" and "row" in fact contains
+        inplace_chunk_size contiguous true columns and rows of z. Writing output chunks to a new tensor would bring
+        total memory consumption down to 3x the size of z. However, more memory can be saved by writing output chunks
+        directly to z in-place. WLOG, we choose to write output chunks vertically, overwriting the ith "column" of z at
+        the end of the ith iteration of the main loop. Despite this overwriting, the ith column is always one column
+        ahead of previously overwritten columns and can be recovered directly from z. After the first iteration,
+        however, the ith row of z is always at least partially overwritten. For this reason, we introduce the z-cache,
+        a tensor one-half the size of z. The z-cache initially contains the left half (2nd and 3rd quadrants) of z. For
+        0 < i < N/2, the missing left part of the ith row of z is recovered from this cache at the beginning of the ith
+        iteration. Once i exceeds n/2, the cache is "reoriented" to encompass the 3rd and 4th quadrants of z instead.
+        Though the 3rd quadrant of the original z is entirely overwritten at this point, it can be recovered from the
+        z-cache itself. Thereafter, the ith row of z can be recovered in its entirety from the reoriented z-cache.
+        After the final iteration, z has been completely overwritten and contains the triangular multiplicative update.
+        If with_add is True, it instead contains the sum of z and the triangular multiplicative update. In either case,
+        peak memory consumption is just 2.5x the size of z, disregarding memory used for chunks and other small
+        variables.

+    sliding_window_pattern (`str`, *optional*):
+        The pattern to use for sliding window attention. Can be one of:
+            - `None`: No sliding window attention is used
+            - `int`: Every `sliding_window` layers, use global attention, else use local attention.
+            - `str`: A sequence of "L" (local attention) and "G" (global attention) characters that defines the
+              attention pattern. The pattern starts from layer 0 and repeats every `sliding_window` layers. The
+              final layer always uses global attention regardless of the pattern.
+        For instance, sliding_window_pattern="LLLG" same as sliding_window=4, which means:
+            - Layer 0, 1, 2: local attention,
+            - Layer 3: global attention,
+            ...(repeated)
+
+    Example:
+
+    ```python
+    >>> from transformers import Exaone4Model, Exaone4Config
+
+    >>> # Initializing a EXAONE configuration
+    >>> configuration = Exaone4Config()

+        This argument corresponds to `use_mambapy` in MambaConfig.
+        Determines the fallback strategy during training if the CUDA-based official implementation of Mamba is not available. If `True`, the mamba.py implementation is used. If `False`, the naive and slower implementation is used. Consider switching to the naive version if memory is limited.

+        sequential implementation. The associative scan is only active during `torch.compile` tracing and
+        requires torch >= 2.9.0. Both paths are tested to produce numerically identical results (see

+    expand (`int`, *optional*, defaults to 2):
+        Expanding factor used to determine the intermediate size.
+    conv_kernel (`int`, *optional*, defaults to 4):
+        Size of the convolution kernel.
+    use_bias (`bool`, *optional*, defaults to `False`):
+        Whether or not to use bias in ["in_proj", "out_proj"] of the mixer block
+    use_conv_bias (`bool`, *optional*, defaults to `True`):
+        Whether or not to use bias in the convolution layer of the mixer block.
+    residual_in_fp32 (`bool`, *optional*, defaults to `True`):
+        Whether or not residuals should be in `float32`. If set to `False` residuals will keep the same `dtype` as the rest of the model
+    rescale_prenorm_residual (`bool`, *optional*, defaults to `False`):
+        Whether or not to rescale `out_proj` weights when initializing.
+    use_falcon_mambapy (`bool`, *optional*, defaults to `False`):
+        This argument corresponds to `use_mambapy` in MambaConfig.
+        Determines the fallback strategy during training if the CUDA-based official implementation of Mamba is not available. If `True`, the mamba.py implementation is used. If `False`, the naive and slower implementation is used. Consider switching to the naive version if memory is limited.
+    use_associative_scan (`bool`, *optional*, defaults to `True`):
+        Whether to use PyTorch's `torch._higher_order_ops.associative_scan` for the parallel scan instead of the naive
+        sequential implementation. The associative scan is only active during `torch.compile` tracing and
+        requires torch >= 2.9.0. Both paths are tested to produce numerically identical results (see
+        `test_associative_scan_matches_sequential`). Set to `False` to fall back to the sequential loop.
+    mixer_rms_eps (`float`, *optional*, defaults to 1e-06):
+        The RMS norm epsilon value that is used in the Mixer RMS norm for B, C and dt states.
+
+    Example:
+
+    ```python
+    >>> from transformers import FalconMambaConfig, FalconMambaModel

+        Whether or not to add a projection after the vector extraction.
+    summary_activation (`str`, *optional*):
+        Argument used when doing sequence summary. Used in the sequence classification and multiple choice models.
+        Pass `"tanh"` for a tanh activation to the output, any other value will result in no activation.

+    - The arguments `special_tokens` and the function `set_special_tokens`, can be used to add additional symbols (like
+      "__classify__") to a vocabulary.
+    - The argument `do_lowercase` controls lower casing (automatically set for pretrained vocabularies).
+

+    this superclass for more information regarding those methods.

+        are preserved: Hq·Hk = q·k), and FP8 quantization is a precision optimization, we skip both and compute
+        scores directly in bf16/fp32.
+
+        The scoring logic computes:
+            index_score[b,s,t] = Σ_h (weight[b,s,h] · softmax_scale · q[b,s,h,:] · k[b,t,:])
+
+        Args:
+            hidden_states: Input hidden states `[B, S, hidden_size]`.
+            q_resid: Query residual from `q_a_layernorm(q_a_proj(x))`, shape `[B, S, q_lora_rank]`.
+            position_embeddings: `(cos, sin)` from RotaryEmbedding.
+            attention_mask: Causal mask, broadcastable to `[B, S, T]`.

+    ```python
+    >>> from transformers import GPT2Tokenizer
+
+    >>> tokenizer = GPT2Tokenizer.from_pretrained("openai-community/gpt2")
+    >>> tokenizer("Hello world")["input_ids"]
+    [15496, 995]
+
+    >>> tokenizer(" Hello world")["input_ids"]
+    [18435, 995]
+    ```
+
+    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 [`TokenizersBackend`] which contains most of the main methods. Users should refer to
+    this superclass for more information regarding those methods.
+
+    Args:
+        vocab_file (`str`):
+            Path to the vocabulary file.

+            Path to the merges file.
+        errors (`str`, *optional*, defaults to `"replace"`):
+            Paradigm to follow when decoding bytes to UTF-8. See
+            [bytes.decode](https://docs.python.org/3/library/stdtypes.html#bytes.decode) for more information.
+        unk_token (`str`, *optional*, defaults to `"<|endoftext|>"`):
+            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 `"<|endoftext|>"`):
+            The beginning of sequence token.

+            The end of sequence token.
+        pad_token (`str`, *optional*):
+            The token used for padding, for example when batching sequences of different lengths.
+        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. (GPT2 tokenizer detect beginning of words by the preceding space).
+        add_bos_token (`bool`, *optional*, defaults to `False`):
+            Whether or not to add an initial beginning of sentence token to the input. This allows to treat the leading
+            word just as any other word.
+        vocab (`str` or `dict[str, int]`, *optional*):

+    models (e.g. GPT-1) do.
+
+    Since it does classification on the last token, it requires to know the position of the last token. If a
+    `pad_token_id` is defined in the configuration, it finds the last token that is not a padding token in each row. If
+    no `pad_token_id` is defined, it simply takes the last value in each row of the batch. Since it cannot guess the
+    padding tokens when `inputs_embeds` are passed instead of `input_ids`, it does the same (take the last value in
+    each row of the batch).

+    Construct a GPT-NeoX-20B 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 GPTNeoXTokenizer
+
+    >>> tokenizer = GPTNeoXTokenizer.from_pretrained("EleutherAI/gpt-neox-20b")
+    >>> 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>
+
+    This tokenizer inherits from [`TokenizersBackend`] which contains most of the main methods. Users should
+    refer to this superclass for more information regarding those methods.

+        errors (`str`, *optional*, defaults to `"replace"`):

+        unk_token (`str`, *optional*, defaults to `"<|endoftext|>"`):
+            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 `"<|endoftext|>"`):

+        add_bos_token (`bool`, *optional*, defaults to `False`):

+        add_eos_token (`bool`, *optional*, defaults to `False`):
+            Whether or not to add an `eos_token` at the end of sequences.

+    This tokenizer inherits from [`PreTrainedTokenizer`] and is based on Japanese special Sub-Word-Encoding that is
+    used in this repository (https://github.com/tanreinama/Japanese-BPEEncoder_V2). Check the repository for details.
+    Japanese has a relatively large vocabulary and there is no separation between words. Furthermore, the language is a
+    combination of hiragana, katakana, and kanji, and variants such as "1" and "①" are often used. In order to cope
+    with these, this tokenizer has the following features
+    - Subword-by-subword segmentation, which is intermediate between byte strings and morphological analysis.
+    - BPEs are created for each Kanji, Hiragana, and Katakana character, and there are no BPEs that cross character
+        types, such as Kanji + Hiragana or Hiragana + Katakana.
+    - All-byte encoding that does not require <unk>.
+    - Independent of UTF codes such as 2-byte and 3-byte characters
+    - Conversion of heterographs to the same token_id
+    - Emoji and Emoticon are grouped into 12 types as special tags.

+    Construct an GPTSw3 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.
+
+    Example usage:
+    ```python
+    >>> from transformers import GPTSw3Tokenizer
+
+    >>> tokenizer = GPTSw3Tokenizer.from_pretrained("AI-Sweden-Models/gpt-sw3-126m")
+    >>> tokenizer("Svenska är kul!")["input_ids"]
+    [1814, 377, 3617, 63504]
+    ```
+
+    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.
+        do_lower_case (`bool`, *optional*, defaults to `False`):
+            Whether or not to lowercase the input when tokenizing.
+        remove_space (`bool`, *optional*, defaults to `False`):
+            Whether or not to strip the text when tokenizing (removing excess spaces before and after the string).
+        keep_accents (`bool`, *optional*, defaults to `False`):
+            Whether or not to keep accents when tokenizing.
+        pad_token (`str`, *optional*):
+            The token used for padding, for example when batching sequences of different lengths. If not provided, will
+            default to '<pad>' or '<unk>' depending on model size.
+        unk_token (`str`, *optional*):
+            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. If not provided, will default to '<unk>'.
+        eos_token (`str`, *optional*):
+            The end of sequence token seen during pretraining. If not provided, will default to '<|endoftext|>'
+        bos_token (`str`, *optional*):
+            The beginning of sequence token that can be used for downstream task, was not seen during pretraining. If
+            not provided, will default to '<s>' or '<|endoftext|>', depending on model size.
+        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:
+

+            - `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.
+
+    Attributes:
+        sp_model (`SentencePieceProcessor`):

+            The whitespaces that are replaced in the whitespace normalization in preprocessing.

+    num_queries (`int`, *optional*, defaults to 900):
+        Number of object queries, i.e. detection slots. This is the maximal number of objects
+        [`GroundingDinoModel`] can detect in a single image.
+    position_embedding_type (`str`, *optional*, defaults to `"sine"`):
+        Type of position embeddings to be used on top of the image features. One of `"sine"` or `"learned"`.

+    two_stage (`bool`, *optional*, defaults to `True`):
+        Whether to apply a two-stage deformable DETR, where the region proposals are also generated by a variant of
+        Grounding DINO, which are further fed into the decoder for iterative bounding box refinement.
+    disable_custom_kernels (`bool`, *optional*, defaults to `False`):
+        Disable the use of custom CUDA and CPU kernels. This option is necessary for the ONNX export, as custom
+        kernels are not supported by PyTorch ONNX export.
+    max_text_len (`int`, *optional*, defaults to 256):
+        The maximum length of the text input.
+    text_enhancer_dropout (`float`, *optional*, defaults to 0.0):
+        The dropout ratio for the text enhancer.

+        The dropout ratio for the fusion module.
+    embedding_init_target (`bool`, *optional*, defaults to `True`):
+        Whether to initialize the target with Embedding weights.
+    query_dim (`int`, *optional*, defaults to 4):
+        The dimension of the query vector.
+    decoder_bbox_embed_share (`bool`, *optional*, defaults to `True`):
+        Whether to share the bbox regression head for all decoder layers.
+    two_stage_bbox_embed_share (`bool`, *optional*, defaults to `False`):
+        Whether to share the bbox embedding between the two-stage bbox generator and the region proposal
+        generation.
+    positional_embedding_temperature (`float`, *optional*, defaults to 20):
+        The temperature for Sine Positional Embedding that is used together with vision backbone.
