|
| | class HunYuanConfig(PretrainedConfig): |
| | r""" |
| | This is the configuration class to store the configuration of a [`HunYuanModel`]. It is used to instantiate an |
| | HunYuan 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 HunYuan-7B. |
| | |
| | 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 32000): |
| | Vocabulary size of the HunYuan model. Defines the number of different tokens that can be represented by the |
| | `inputs_ids` passed when calling [`HunYuanModel`] |
| | hidden_size (`int`, *optional*, defaults to 4096): |
| | Dimension of the hidden representations. |
| | intermediate_size (`int`, *optional*, defaults to 11008): |
| | Dimension of the MLP representations or shared MLP representations. |
| | moe_intermediate_size (`int` or `List`, *optional*, defaults to 11008): |
| | Dimension of the MLP representations in MoE. Use a list if you want a different size per layer. |
| | num_hidden_layers (`int`, *optional*, defaults to 32): |
| | Number of hidden layers in the Transformer decoder. |
| | num_attention_heads (`int`, *optional*, defaults to 32): |
| | Number of attention heads for each attention layer in the Transformer decoder. |
| | 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 2048): |
| | 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 1): |
| | Beginning of stream token id. |
| | eos_token_id (`int`, *optional*, defaults to 2): |
| | 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. See the following thread for more information on how |
| | these scaling strategies behave: |
| | https://www.reddit.com/r/LocalLLaMA/comments/14mrgpr/dynamically_scaled_rope_further_increases/. This is an |
| | experimental feature, subject to breaking API changes in future versions. |
| | 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. |
| | use_qk_norm (`bool`, *optional*, defaults to `False`): |
| | Whether query and key in attention use norm |
| | use_cla (`bool`, *optional*, defaults to `False`): |
| | Whether to use CLA in attention |
| | cla_share_factor (`int`, *optional*, defaults to 1): |
| | The share factor of CLA |
| | num_experts (`int` or `List`, *optional*, defaults to 1): |
| | The number of experts for moe. If it is a list, it will be used as the number of experts for each layer. |
| | num_shared_expert (`int` or `List`, *optional*, defaults to 1): |
| | The number of shared experts for moe. If it is a list, it will be used as the number of shared experts for each layer. |
| | moe_topk (`int` or `List`, *optional*, defaults to 1): |
| | The topk value for moe. If it is a list, it will be used as the topk value for each layer. |
| | capacity_factor (Not used) (`float` or `List`, *optional*, defaults to 1.0): |
| | The capacity factor for moe. If it is a list, it will be used as the capacity factor for each layer. |
| | moe_layer_num_skipped (`int`, *optional*, defaults to 0): |
| | First moe_layer_num_skipped layers do not use MoE. |
