31
+ r"""
32
+ This is the configuration class to store the configuration of a [`PhiModel`]. It is used to instantiate an Phi
33
+ model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
34
+ defaults will yield a similar configuration to that of the Phi
35
+ [microsoft/phi-1](https://huggingface.co/microsoft/phi-1).
36
+
37
+ Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
38
+ documentation from [`PretrainedConfig`] for more information.
39
+
40
+ Args:
41
+ vocab_size (`int`, *optional*, defaults to 51200):
42
+ Vocabulary size of the Phi model. Defines the number of different tokens that can be represented by the
43
+ `inputs_ids` passed when calling [`PhiModel`].
44
+ hidden_size (`int`, *optional*, defaults to 2048):
45
+ Dimension of the hidden representations.
46
+ intermediate_size (`int`, *optional*, defaults to 8192):
47
+ Dimension of the MLP representations.
48
+ num_hidden_layers (`int`, *optional*, defaults to 24):
49
+ Number of hidden layers in the Transformer decoder.
50
+ num_attention_heads (`int`, *optional*, defaults to 32):
51
+ Number of attention heads for each attention layer in the Transformer decoder.
52
+ num_key_value_heads (`int`, *optional*):
53
+ This is the number of key_value heads that should be used to implement Grouped Query Attention. If
54
+ `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
55
+ `num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
56
+ converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
57
+ by meanpooling all the original heads within that group. For more details checkout [this
58
+ paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to
59
+ `num_attention_heads`.
60
+ resid_pdrop (`float`, *optional*, defaults to 0.0):
61
+ Dropout probability for mlp outputs.
62
+ embd_pdrop (`int`, *optional*, defaults to 0.0):
63
+ The dropout ratio for the embeddings.
64
+ attention_dropout (`float`, *optional*, defaults to 0.0):
65
+ The dropout ratio after computing the attention scores.
66
+ hidden_act (`str` or `function`, *optional*, defaults to `"gelu_new"`):
67
+ The non-linear activation function (function or string) in the decoder.
68
+ max_position_embeddings (`int`, *optional*, defaults to 2048):
69
+ The maximum sequence length that this model might ever be used with. Phi-1 and Phi-1.5 supports up to 2048
70
+ tokens.
71
+ initializer_range (`float`, *optional*, defaults to 0.02):
72
+ The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
73
+ layer_norm_eps (`float`, *optional*, defaults to 1e-05):
74
+ The epsilon used by the rms normalization layers.
75
+ use_cache (`bool`, *optional*, defaults to `True`):
76
+ Whether or not the model should return the last key/values attentions (not used by all models). Only
77
+ relevant if `config.is_decoder=True`. Whether to tie weight embeddings or not.
78
+ tie_word_embeddings (`bool`, *optional*, defaults to `False`):
79
+ Whether to tie weight embeddings
80
+ rope_theta (`float`, *optional*, defaults to 10000.0):
81
+ The base period of the RoPE embeddings.
82
+ rope_scaling (`Dict`, *optional*):
83
+ Dictionary containing the scaling configuration for the RoPE embeddings. Currently supports two scaling
84
+ strategies: linear and dynamic. Their scaling factor must be an float greater than 1. The expected format
85
+ is `{"type": strategy name, "factor": scaling factor}`. When using this flag, don't update
86
+ `max_position_embeddings` to the expected new maximum. See the following thread for more information on how
87
+ these scaling strategies behave:
88
+ https://www.reddit.com/r/LocalPersimmon/comments/14mrgpr/dynamically_scaled_rope_further_increases/. This
89
+ is an experimental feature, subject to breaking API changes in future versions.
90
+ partial_rotary_factor (`float`, *optional*, defaults to 0.5):
91
+ Percentage of the query and keys which will have rotary embedding.
92
+ qk_layernorm (`bool`, *optional*, defaults to `False`):
93
+ Whether or not to normalize the Queries and Keys after projecting the hidden states.
94
+ bos_token_id (`int`, *optional*, defaults to 1):
95
+ Denotes beginning of sequences token id.
96
+ eos_token_id (`int`, *optional*, defaults to 2):
97
+ Denotes end of sequences token id.
98
+
99
+ Example:
100
+
101
+ ```python
102
+ >>> from transformers import PhiModel, PhiConfig
103
+
104
+ >>> # Initializing a Phi-1 style configuration
105
+ >>> configuration = PhiConfig.from_pretrained("microsoft/phi-1")
106
+
107
+ >>> # Initializing a model from the configuration
108
