from transformers import PretrainedConfig
class AXK1Config(PretrainedConfig):
r"""
This is the configuration class to store the configuration of a [`AXK1Model`].
It is used to instantiate an A.X 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 A.X K1.
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 163840):
Vocabulary size of the A.X K1 model. Defines the number of different
tokens that can be represented by the `inputs_ids` passed when calling
[`AXK1Model`]
hidden_size (`int`, *optional*, defaults to 7168):
Dimension of the hidden representations.
intermediate_size (`int`, *optional*, defaults to 18432):
Dimension of the MLP representations.
moe_intermediate_size (`int`, *optional*, defaults to 2048):
Dimension of the MoE representations.
num_hidden_layers (`int`, *optional*, defaults to 61):
Number of hidden layers in the Transformer decoder.
num_nextn_predict_layers (`int`, *optional*, defaults to 1):
Number of nextn predict layers in the AXK1 Model.
num_attention_heads (`int`, *optional*, defaults to 64):
Number of attention heads for each attention layer in the Transformer
decoder.
n_shared_experts (`int`, *optional*, defaults to 1):
Number of shared experts, None means dense model.
n_routed_experts (`int`, *optional*, defaults to 192):
Number of routed experts, None means dense model.
routed_scaling_factor (`float`, *optional*, defaults to 2.5):
Scaling factor or routed experts.
topk_method (`str`, *optional*, defaults to `noaux_tc`):
Topk method used in routed gate.
n_group (`int`, *optional*, defaults to 8):
Number of groups for routed experts.
topk_group (`int`, *optional*, defaults to 4):
Number of selected groups for each token(for each token, ensuring the
selected experts is only within `topk_group` groups).
num_experts_per_tok (`int`, *optional*, defaults to 8):
Number of selected experts, None means dense model.
moe_layer_freq (`int`, *optional*, defaults to 1):
The frequency of the MoE layer: one expert layer for every
`moe_layer_freq - 1` dense layers.
first_k_dense_replace (`int`, *optional*, defaults to 1):
Number of dense layers in shallow layers
(embed->dense->dense->...->dense->moe->moe...->lm_head).
\--k dense layers--/
norm_topk_prob (`bool`, *optional*, defaults to True):
Whether to normalize the weights of the routed experts.
scoring_func (`str`, *optional*, defaults to 'sigmoid'):
Method of computing expert weights.
aux_loss_alpha (`float`, *optional*, defaults to 0.0001):
Auxiliary loss weight coefficient.
seq_aux = (`bool`, *optional*, defaults to True):
Whether to compute the auxiliary loss for each individual sample.
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=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 `num_attention_heads`.
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 131072):
The maximum sequence length that this model might ever be used with.
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*):
Padding token id.
bos_token_id (`int`, *optional*, defaults to 163691):
Beginning of stream token id.
eos_token_id (`int`, *optional*, defaults to 163691):
End of stream token id.
pretraining_tp (`int`, *optional*, defaults to 1):
Experimental feature. Tensor parallelism rank used during pretraining.
Please refer to
[this document](https://huggingface.co/docs/transformers/parallelism)
to understand more about it. This value is necessary to ensure exact
reproducibility of the pretraining results. Please refer to
[this issue](https://github.com/pytorch/pytorch/issues/76232).
tie_word_embeddings (`bool`, *optional*, defaults to `False`):
Whether to tie weight embeddings
rope_theta (`float`, *optional*, defaults to 10000.0):
The base period of the RoPE embeddings.
rope_scaling (`Dict`, *optional*):
Dictionary containing the scaling configuration for the RoPE embeddings.
Currently supports two scaling strategies: linear and dynamic.
Their scaling factor must be a float greater than 1. The expected format
is `{"type": strategy name, "factor": scaling factor}`. When using this
flag, don't update `max_position_embeddings` to the expected new maximum.
attention_bias (`bool`, defaults to `False`, *optional*, defaults to `False`):
Whether to use a bias in the query, key, value and output projection
layers during self-attention.
attention_dropout (`float`, *optional*, defaults to 0.0):
The dropout ratio for the attention probabilities.
