	""" Sparsetral model configuration"""

	from transformers.configuration_utils import PretrainedConfig
	from transformers.utils import logging


	logger = logging.get_logger(__name__)


	class SparsetralConfig(PretrainedConfig):
	r"""
	This is the configuration class to store the configuration of a [`MistralModel`]. It is used to instantiate an
	Mistral 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 Mistral-7B-v0.1 or Mistral-7B-Instruct-v0.1.

	[mistralai/Mistral-7B-v0.1](https://huggingface.co/mistralai/Mistral-7B-v0.1)
	[mistralai/Mistral-7B-Instruct-v0.1](https://huggingface.co/mistralai/Mistral-7B-Instruct-v0.1)

	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 32000):
	Vocabulary size of the Mistral model. Defines the number of different tokens that can be represented by the
	`inputs_ids` passed when calling [`MistralModel`]
	hidden_size (`int`, optional, defaults to 4096):
	Dimension of the hidden representations.
	intermediate_size (`int`, optional, defaults to 14336):
	Dimension of the MLP representations.
	num_hidden_layers (`int`, optional, defaults to 32):
	Number of hidden layers in the Transformer encoder.
	num_attention_heads (`int`, optional, defaults to 32):
	Number of attention heads for each attention layer in the Transformer encoder.
	num_key_value_heads (`int`, optional, defaults to 8):
	This is the number of key_value heads that should be used to implement Grouped Query Attention. If
	`num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
	`num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
	converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
	by meanpooling all the original heads within that group. For more details checkout [this
	paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to `8`.
	hidden_act (`str` or `function`, optional, defaults to `"silu"`):
	The non-linear activation function (function or string) in the decoder.
	max_position_embeddings (`int`, optional, defaults to `4096*32`):
	The maximum sequence length that this model might ever be used with. Mistral's sliding window attention
	allows sequence of up to 4096*32 tokens.
	initializer_range (`float`, optional, defaults to 0.02):
	The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
	rms_norm_eps (`float`, optional, defaults to 1e-06):
	The epsilon used by the rms normalization layers.
	use_cache (`bool`, optional, defaults to `True`):
	Whether or not the model should return the last key/values attentions (not used by all models). Only
	relevant if `config.is_decoder=True`.
	pad_token_id (`int`, optional):
	The id of the padding token.
	bos_token_id (`int`, optional, defaults to 1):
	The id of the "beginning-of-sequence" token.
	eos_token_id (`int`, optional, defaults to 2):
	The id of the "end-of-sequence" token.
	tie_word_embeddings (`bool`, optional, defaults to `False`):
	Whether the model's input and output word embeddings should be tied.
	rope_theta (`float`, optional, defaults to 10000.0):
	The base period of the RoPE embeddings.
	sliding_window (`int`, optional, defaults to 4096):
	Sliding window attention window size. If not specified, will default to `4096`.
	attention_dropout (`float`, optional, defaults to 0.0):
	The dropout ratio for the attention probabilities.
