It is used to instantiate a Zamba2 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 Zamba2 model. [Zyphra/Zamba2-2.7B](https://huggingface.co/Zyphra/Zamba2-2.7B) 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 Zamba2 model. Defines the number of different tokens that can be represented by the `inputs_ids` passed when calling [`Zamba2Model`] max_position_embeddings (`int`, *optional*, defaults to 4096): The maximum sequence length that this model might ever be used with. hidden_size (`int`, *optional*, defaults to 2560): Dimension of the hidden representations. num_hidden_layers (`int`, *optional*, defaults to 54): Number of hidden layers in the model. layers_block_type (`list`, *optional*): List of layer types, which can be either "mamba" or "hybrid". mamba_d_state (`int`, *optional*, defaults to 64): shape of the state space latents. mamba_d_conv (`int`, *optional*, defaults to 4): Size of the convolution kernel. mamba_expand (`int`, *optional*, defaults to 2): Expanding factor used to determine the intermediate size. mamba_ngroups (`int`, *optional*, defaults to 1): Number of groups for the evolution matrices of mamba 2. time_step_min (`float`, *optional*, defaults to 0.001): Minimum `time_step` used to bound `dt_proj.bias`. time_step_max (`float`, *optional*, defaults to 0.1): Maximum `time_step` used to bound `dt_proj.bias`. time_step_floor (`float`, *optional*, defaults to 0.0001): Minimum clamping value of the `dt_proj.bias` layer initialization. time_step_limit (`tuple`, *optional*): Accepted range of time step values. n_mamba_heads (`int`, *optional*, defaults to 8): Number of heads for the evolution matrices of mamba 2. use_conv_bias (`bool`, *optional*, defaults to `True`): Whether or not to use bias in the convolution layer of the mixer block. chunk_size (`int`, *optional*, defaults to 256): Size of the chunks that will comprise the sequence. use_mem_eff_path (`bool`, *optional*, defaults to `False`): Whether or not to use the fused conv1d and scan in mamba2 layers. add_bias_linear (`bool`, *optional*, defaults to `False`): Flag indicating whether or not to use bias in various layers intermediate_size (`int`, *optional*, defaults to 4 * hidden_size): Dimension of the MLP representations. hidden_act (`str`, *optional*, defaults to `"gelu"`): The non-linear activation function (function or string) in the MLP. num_attention_heads (`int`, *optional*, defaults to 32): Number of attention heads for each attention layer in the Transformer decoder. num_key_value_heads (`int`, *optional*): This is the number of key_value heads that should be used to implement Grouped Query Attention. If `num_key_value_heads=None`, 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, check out [this paper](https://huggingface.co/papers/2305.13245). attention_dropout (`float`, *optional*, defaults to 0.0): The dropout ratio for the attention probabilities. num_mem_blocks (`int`, *optional*, defaults to 1): Number of unshared transformer blocks. use_shared_attention_adapter (`bool`, *optional*, defaults to `False`): If True, unshared adapters (formally the same as LoRA but used in the base model) will be added to the q, k, v projectors in the shared attention layers. adapter_rank (`int`, *optional*, defaults to 128): Rank of the adapter in the shared MLP and shared attention layers. use_mem_rope (`bool`, *optional*, defaults to `False`): If True, includes RoPE in the shared attention layers. rope_parameters (`RopeParameters`, *optional*): Dictionary containing the configuration parameters for the RoPE embeddings. The dictionary should contain a value for `rope_theta` and optionally parameters used for scaling in case you want to use RoPE with longer `max_position_embeddings`. 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-05): 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`. num_logits_to_keep (`int` or `None`, *optional*, defaults to 1): Number of prompt logits to calculate during generation. If `None`, all logits will be calculated. If an integer value, only last `num_logits_to_keep` logits will be calculated. Default is 1 because only the logits of the last prompt token are needed for generation. For long sequences, the logits for the entire sequence may use a lot of memory so, setting `num_logits_to_keep=1` will reduce memory footprint significantly. pad_token_id (`int`, *optional*, defaults to 0): 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. use_long_context (`bool`, *optional*, defaults to `False`): Activates the context-extended version of Zamba by modifying RoPE. tie_word_embeddings (`bool`, *optional*, defaults to `True`): Whether to tie weight embeddings ```python >>> from transformers import Zamba2Model, Zamba2Config >>> # Initializing a Zamba2-2.7B style configuration >>> configuration = Zamba2Config() >>> # Initializing a model from the Zamba2-2.7B style configuration >>> model = Zamba2Model(configuration) >>> # Accessing the model configuration >>> configuration = model.config ```Úzamba2Úhead_dimÚattention_head_dimÚpast_key_valuesé}éé é6Né@éééçü©ñÒMbP?çš™™™™™¹?ç-Cëâ6?éTéFÚgelué çé€ç{®Gáz”?çñh㈵øä>éÚ vocab_sizeÚmax_position_embeddingsÚ hidden_sizeÚnum_hidden_layersÚlayers_block_typeÚ mamba_d_stateÚ mamba_d_convÚ mamba_expandÚ mamba_ngroupsÚ time_step_minÚ time_step_maxÚtime_step_floorÚtime_step_limitÚ n_mamba_headsÚ use_conv_biasÚ chunk_sizeÚuse_mem_eff_pathÚadd_bias_linearÚintermediate_sizeÚ hidden_actÚnum_attention_headsÚnum_key_value_headsÚattention_dropoutÚnum_mem_blocksÚuse_shared_attention_adapterÚ adapter_rankÚ use_mem_ropeÚrope_parametersÚinitializer_rangeÚ rms_norm_epsÚ use_cacheÚnum_logits_to_keepÚ pad_token_idÚ bos_token_idÚ eos_token_idÚuse_long_contextÚtie_word_embeddingsc&' sÎ|!|_|"|_|#|_|%|_||_||_||_|durd||_n||_||_||_ ||_ ||_ d||_ d|j|j |_ ||_||_|$|_||_||_||_||_||_| |_||_t||ƒ||_||_||_| |_||_||_| |_| |_ | |_!|$r€d|_|dur†|}||_"||_ |j|j |_#|j |_$|dur¿dgdgddgddgddgdgddgdgd|_%n||_%||_&||_'||_(| |_)d d „t*|j%ƒDƒ|_+||_,t-ƒj.d i|&¤ŽdS) Nrri@ÚmambaéÚhybridércSsg|] \}}|dkr|‘qS)rD©)Ú.0ÚindexÚtyperFrFúm/home/ubuntu/transcripts/venv/lib/python3.10/site-packages/transformers/models/zamba2/configuration_zamba2.pyÚ ész)Zamba2Config.__init__..rF)/r=r>r?rArrrr/r0r r1r4Úattention_hidden_sizerr3r7r@r8r"r#r$r.r%r*ÚintÚ mamba_headdimr+r,r)r5r6r&r'r(r2Ú kv_channelsÚnum_query_groupsr!r9r:r;r<Ú enumerateÚhybrid_layer_idsr-ÚsuperÚ__init__)'Úselfrrrr r!r"r#r$r%r&r'r(r)r*r+r,r-r.r/r0r1r2r3r4r5r6r7r8r9r:r;r<r=r>r?r@rAÚkwargs©Ú __class__rFrJrT‚s„)  ÿþýüûúÿ zZamba2Config.__init__)%r r r r Nr rrrrrrNrTrFFNrrNrrFrFNrrTrrrrFT)Ú__name__Ú __module__Ú __qualname__Ú__doc__Ú model_typeÚ attribute_mapÚkeys_to_ignore_at_inferencerMÚlistÚstrÚfloatÚboolrÚdictrTÚ __classcell__rFrFrWrJrsêhÚþýüû úùø ÷ ö õ ô óòñðïîíìëêéèçæåäãâá à!ß"Þ#Ý$Ü%Û&ÚrN)Úconfiguration_utilsrÚmodeling_rope_utilsrrÚ__all__rFrFrFrJÚs   Z
