class LlavaNextVideoConfig(PreTrainedConfig):
    r"""
    This is the configuration class to store the configuration of a [`LlavaNextVideoForConditionalGeneration`]. It is used to instantiate an
    Llava-NeXT 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 [llava-hf/LLaVA-NeXT-Video-7B-hf](https://huggingface.co/llava-hf/LLaVA-NeXT-Video-7B-hf)
    model.
    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 (`Union[AutoConfig, dict]`,  *optional*, defaults to `CLIPVisionConfig`):
            The config object or dictionary of the vision backbone.
        text_config (`Union[AutoConfig, dict]`, *optional*, defaults to `LlamaConfig`):
            The config object or dictionary of the text backbone.
        image_token_index (`int`, *optional*, defaults to 32001):
            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.
        multimodal_projector_bias (`bool`, *optional*, defaults to `True`):
            Whether to use bias in the multimodal projector.
        vision_feature_select_strategy (`str`, *optional*, defaults to `"default"`):
            The feature selection strategy used to select the vision feature from the vision backbone.
            Can be one of `"default"` or `"full"`. If `"default"`, the CLS token is removed from the vision features.
            If `"full"`, the full vision features are used.
        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_grid_pinpoints (`List`, *optional*, defaults to `[[336, 672], [672, 336], [672, 672], [1008, 336], [336, 1008]]`):
            A list of possible resolutions to use for processing high resolution images. Each item in the list should be a tuple or list
            of the form `(height, width)`.
        video_token_index (`int`, *optional*, defaults to 32000):
            The video token index to encode the image prompt.
        spatial_pool_mode (`str`, *optional*, defaults to `"average"`):
            Pooling mode to use for videos. Can be "average", "max" or "conv".
        spatial_pool_stride (`int`, *optional*, defaults to 2):
            Stride used in the pooling layer for videos.
        image_seq_length (`int`, *optional*, defaults to 576):
            Sequence length of one image embedding.
        video_seq_length (`int`, *optional*, defaults to 288):
            Sequence length of one video embedding.
        tie_word_embeddings (`bool`, *optional*, defaults to `False`):
            Whether to tie weight embeddings

    Example:

    ```python
    >>> from transformers import LlavaNextVideoForConditionalGeneration, LlavaNextVideoConfig, CLIPVisionConfig, LlamaConfig

    >>> # Initializing a CLIP-vision config
    >>> vision_config = CLIPVisionConfig()

    >>> # Initializing a Llama config
    >>> text_config = LlamaConfig()

    >>> configuration = LlavaNextVideoConfig(vision_config, text_config)

    >>> model = LlavaNextVideoForConditionalGeneration(configuration)

    >>> # Accessing the model configuration
    >>> configuration = model.config
