8
+ r"""
9
+ This is the configuration class to store the configuration of a [`DeepseekV2Model`]. It is used to instantiate an DeepSeek
10
+ model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
11
+ defaults will yield a similar configuration to that of the DeepSeek-V2.
12
+
13
+ Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
14
+ documentation from [`PretrainedConfig`] for more information.

18
+ vocab_size (`int`, *optional*, defaults to 102400):

32

43
+ num_experts_per_tok (`int`, *optional*, defaults to None):
44
+ Number of selected experts, None means dense model.
45
+ moe_layer_freq (`int`, *optional*, defaults to 1):

+ `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
61
+ `num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
62
+ converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
63
+ by meanpooling all the original heads within that group. For more details checkout [this
64
+ paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to

84
+ Experimental feature. Tensor parallelism rank used during pretraining. Please refer to [this
85
+ document](https://huggingface.co/docs/transformers/parallelism) to understand more about it. This value is
86
