	logger = logging.get_logger(__name__)


	class MraConfig(PretrainedConfig):
	r"""
	This is the configuration class to store the configuration of a [`MraModel`]. It is used to instantiate an MRA
	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 Mra
	[uw-madison/mra-base-512-4](https://huggingface.co/uw-madison/mra-base-512-4) 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 50265):
	Vocabulary size of the Mra model. Defines the number of different tokens that can be represented by the
	`inputs_ids` passed when calling [`MraModel`].
	hidden_size (`int`, optional, defaults to 768):
	Dimension 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):
	Dimension 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 0.1):
	The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
	attention_probs_dropout_prob (`float`, optional, defaults to 0.1):
	The dropout ratio for the attention probabilities.
	max_position_embeddings (`int`, optional, defaults to 512):
	The maximum sequence length that this model might ever be used with. Typically set this to something large
	just in case (e.g., 512 or 1024 or 2048).
	type_vocab_size (`int`, optional, defaults to 1):
	The vocabulary size of the `token_type_ids` passed when calling [`MraModel`].
	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-5):
	The epsilon used by the layer normalization layers.
	position_embedding_type (`str`, optional, defaults to `"absolute"`):
	Type of position embedding. Choose one of `"absolute"`, `"relative_key"`, `"relative_key_query"`.
	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
