30
+ This is the configuration class to store the configuration of a [`Qwen2Model`]. It is used to instantiate a
31
+ Qwen2 model according to the specified arguments, defining the model architecture. Instantiating a configuration
32
+ with the defaults will yield a similar configuration to that of
33
+ Qwen2-7B-beta [Qwen/Qwen2-7B-beta](https://huggingface.co/Qwen/Qwen2-7B-beta).
34
+
35
+ Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
36
+ documentation from [`PretrainedConfig`] for more information.
37
+
38
+
39
+ Args:
40
+ vocab_size (`int`, *optional*, defaults to 151936):
41
+ Vocabulary size of the Qwen2 model. Defines the number of different tokens that can be represented by the
42
+ `inputs_ids` passed when calling [`Qwen2Model`]
43
+ hidden_size (`int`, *optional*, defaults to 4096):
44
+ Dimension of the hidden representations.
45
+ intermediate_size (`int`, *optional*, defaults to 22016):
46
+ Dimension of the MLP representations.
47
+ num_hidden_layers (`int`, *optional*, defaults to 32):
48
+ Number of hidden layers in the Transformer encoder.
49
+ num_attention_heads (`int`, *optional*, defaults to 32):
50
+ Number of attention heads for each attention layer in the Transformer encoder.
51
+ num_key_value_heads (`int`, *optional*, defaults to 32):
52
+ This is the number of key_value heads that should be used to implement Grouped Query Attention. If
53
+ `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
54
+ `num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
55
+ converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
56
+ by meanpooling all the original heads within that group. For more details checkout [this
57
+ paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to `32`.
58
+ hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
59
+ The non-linear activation function (function or string) in the decoder.
60
+ max_position_embeddings (`int`, *optional*, defaults to 32768):
61
+ The maximum sequence length that this model might ever be used with.
62
+ initializer_range (`float`, *optional*, defaults to 0.02):
63
+ The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
64
+ rms_norm_eps (`float`, *optional*, defaults to 1e-06):
65
+ The epsilon used by the rms normalization layers.
66
+ use_cache (`bool`, *optional*, defaults to `True`):
67
+ Whether or not the model should return the last key/values attentions (not used by all models). Only
68
+ relevant if `config.is_decoder=True`.
69
+ tie_word_embeddings (`bool`, *optional*, defaults to `False`):
70
+ Whether the model's input and output word embeddings should be tied.
71
+ rope_theta (`float`, *optional*, defaults to 10000.0):
72
+ The base period of the RoPE embeddings.
73
+ use_sliding_window (`bool`, *optional*, defaults to `False`):
74
+ Whether to use sliding window attention.
75
+ sliding_window (`int`, *optional*, defaults to 4096):
76
+ Sliding window attention (SWA) window size. If not specified, will default to `4096`.
77
+ max_window_layers (`int`, *optional*, defaults to 28):
78
+ The number of layers that use SWA (Sliding Window Attention). The bottom layers use SWA while the top use full attention.
79
+ attention_dropout (`float`, *optional*, defaults to 0.0):
80
+ The dropout ratio for the attention probabilities.
