It is used to instantiate an MiniCPM34 model according to the specified arguments, defining the model architecture. Instantiating a configuration with the35 defaults will yield a similar configuration to that of the MiniCPM-7B.36 37 Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the38 documentation from [`PretrainedConfig`] for more information.39 40 41 Args:42 vocab_size (`int`, *optional*, defaults to 32000):43 Vocabulary size of the MiniCPM model. Defines the number of different tokens that can be represented by the44 `inputs_ids` passed when calling [`MiniCPMModel`]45 hidden_size (`int`, *optional*, defaults to 4096):46 Dimension of the hidden representations.47 intermediate_size (`int`, *optional*, defaults to 11008):48 Dimension of the MLP representations.49 num_hidden_layers (`int`, *optional*, defaults to 32):50 Number of hidden layers in the Transformer decoder.51 num_attention_heads (`int`, *optional*, defaults to 32):52 Number of attention heads for each attention layer in the Transformer decoder.53 num_key_value_heads (`int`, *optional*):54 This is the number of key_value heads that should be used to implement Grouped Query Attention. If55 `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if56 `num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When57 converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed58 by meanpooling all the original heads within that group. For more details checkout [this59 paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to60 `num_attention_heads`.61 hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):62 The non-linear activation function (function or string) in the decoder.63 max_position_embeddings (`int`, *optional*, defaults to 2048):64 The maximum sequence length that this model might ever be used with. MiniCPM 1 supports up to 2048 tokens,65 MiniCPM 2 up to 4096, CodeMiniCPM up to 16384.66 initializer_range (`float`, *optional*, defaults to 0.02):67 The standard deviation of the truncated_normal_initializer for initializing all weight matrices.68 rms_norm_eps (`float`, *optional*, defaults to 1e-06):69 The epsilon used by the rms normalization layers.70 use_cache (`bool`, *optional*, defaults to `True`):71 Whether or not the model should return the last key/values attentions (not used by all models). Only72 relevant if `config.is_decoder=True`.73 pad_token_id (`int`, *optional*):74 Padding token id.75 bos_token_id (`int`, *optional*, defaults to 1):76 Beginning of stream token id.77 eos_token_id (`int`, *optional*, defaults to 2):78 End of stream token id.79 pretraining_tp (`int`, *optional*, defaults to 1):80 Experimental feature. Tensor parallelism rank used during pretraining. Please refer to [this81 document](https://huggingface.co/docs/transformers/parallelism) to understand more about it. This value is82 necessary to ensure exact reproducibility of the pretraining results. Please refer to [this83 issue](https://github.com/pytorch/pytorch/issues/76232).84 tie_word_embeddings (`bool`, *optional*, defaults to `False`):85 Whether to tie weight embeddings86 rope_theta (`float`, *optional*, defaults to 10000.0):87 The base period of the RoPE embeddings.88 rope_scaling (`Dict`, *optional*):89 Dictionary containing the scaling configuration for the RoPE embeddings. Currently supports two scaling90 strategies: linear and dynamic. Their scaling factor must be a float greater than 1. The expected format is91 `{"type": strategy name, "factor": scaling factor}`. When using this flag, don't update92 `max_position_embeddings` to the expected new maximum. See the following thread for more information on how93 these scaling strategies behave:94 https://www.reddit.com/r/LocalMiniCPM/comments/14mrgpr/dynamically_scaled_rope_further_increases/. This is an95 experimental feature, subject to breaking API changes in future versions.96 attention_bias (`bool`, defaults to `False`, *optional*, defaults to `False`):97 Whether to use a bias in the query, key, value and output projection layers during self-attention.98 attention_dropout (`float`, *optional*, defaults to 0.0):99 The dropout ratio for the attention probabilities.100 101 ```python102 >>> from transformers import MiniCPMModel, MiniCPMConfig103 104 >>> # Initializing a MiniCPM minicpm-7b style configuration105 >>> configuration = MiniCPMConfig()106 107 >>> # Initializing a model from the minicpm-7b style configuration108 >>> model = MiniCPMModel(configuration)109 110 >>> # Accessing the model configuration111 >>> configuration = model.config112 ```"""113 114 model_type = "minicpm"115 keys_to_ignore_at_inference = ["past_key_values"]116 117 def __init__(118 self,119 vocab_size=32000,120 hidden_size=4096,121 intermediate_size=11008,122 num_hidden_layers=32,123 num_attention_heads=32,124 num_key_value_heads=None,125 hidden_act="silu",126 max_position_embeddings=2048,127 initializer_range=0.02,128 rms_norm_eps=1e-6,129 use_cache=True,130 pad_token_id=None,131 bos_token_id=1,132 eos_token_id=2,133 pretraining_tp=1,134 tie_word_embeddings=True,135 rope_theta=10000.0,136 rope_scaling=None,137 attention_bias=False,138 attention_dropout=0.0,139 scale_emb=1,140 dim_model_base=1,141 scale_depth=1,142 **kwargs,143 ):144 self.vocab_size = vocab_size145 self.max_position_embeddings = max_position_embeddings146 self.hidden_size = hidden_size147 self.intermediate_size = intermediate_size148 self.num_hidden_layers = num_hidden_layers149 self.num_attention_heads = num_attention_heads150 151 # for backward compatibility152 if num_key_value_heads is None:153 num_key_value_heads = num_attention_heads154 155 self.num_key_value_heads = num_key_value_heads156 self.hidden_act = hidden_act157 self.initializer_range = initializer_range158 self.rms_norm_eps = rms_norm_eps159 self.pretraining_tp = pretraining_tp160 self.use_cache = use_cache161 self.rope_theta = rope_theta162 self.rope_scaling = rope_scaling163 self._rope_scaling_validation()164 self.attention_bias = attention_bias165 self.attention_dropout = attention_dropout166 self.scale_emb = scale_emb167 self.dim_model_base = dim_model_base168 self.scale_depth = scale_depth169 170 super().__init__(171 pad_token_id=pad_token_id,172 bos_token_id=bos_token_id,173 eos_token_id=eos_token_id,174 tie_word_embeddings=tie_word_embeddings,175 **kwargs,176 )177 try:178 import flash_attn179 self._attn_implementation = "flash_attention_2"180 except:181 pass182 183 def _rope_scaling_validation(self):184 """185 Validate the `rope_scaling` configuration.186 """187 if self.rope_scaling is None:188 return189 190 if not isinstance(self.rope_scaling, dict) or len(self.rope_scaling) != 2:191 raise ValueError(192 "`rope_scaling` must be a dictionary with with two fields, `type` and `factor`, "193 f"got {self.rope_scaling}"194 )195 rope_scaling_type = self.rope_scaling.get("type", None)196 rope_scaling_factor = self.rope_scaling.get("factor", None)197 if rope_scaling_type is None or rope_scaling_type not in ["linear", "dynamic"]:198 raise ValueError(199 f"`rope_scaling`'s type field must be one of ['linear', 'dynamic'], got {rope_scaling_type}"200 )201 if rope_scaling_factor is None or not isinstance(rope_scaling_factor, float) or rope_scaling_factor <= 1.0:202 raise ValueError(f"`rope_scaling`'s factor field must be a float > 1, got {rope_scaling_factor}")203
