    block_per_row (`int`, *optional*, defaults to 4):
        Used to set the budget for the high resolution scale.
    approx_mode (`str`, *optional*, defaults to `"full"`):
        Controls whether both low and high resolution approximations are used. Set to `"full"` for both low and
        high resolution and `"sparse"` for only low resolution.
    initial_prior_first_n_blocks (`int`, *optional*, defaults to 0):
        The initial number of blocks for which high resolution is used.
    initial_prior_diagonal_n_blocks (`int`, *optional*, defaults to 0):
        The number of diagonal blocks for which high resolution is used.

    Example:

    ```python
    >>> from transformers import MraConfig, MraModel

    >>> # Initializing a Mra uw-madison/mra-base-512-4 style configuration
    >>> configuration = MraConfig()

    >>> # Initializing a model (with random weights) from the uw-madison/mra-base-512-4 style configuration
    >>> model = MraModel(configuration)

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