| from transformers.configuration_utils import PretrainedConfig | |
| from transformers.utils import logging | |
| logger = logging.get_logger(__name__) | |
| class ChatGLMConfig(PretrainedConfig): | |
| r""" | |
| This is the configuration class to store the configuration of a [`~ChatGLMModel`]. | |
| It is used to instantiate an ChatGLM 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 ChatGLM-6B [THUDM/ChatGLM-6B](https://huggingface.co/THUDM/chatglm-6b) architecture. | |
| 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 150528): | |
| Vocabulary size of the ChatGLM-6B model. Defines the number of different tokens that can be represented by the | |
| `inputs_ids` passed when calling [`~ChatGLMModel`] or | |
| [`~TFChatGLMModel`]. | |
| hidden_size (`int`, *optional*, defaults to 4096): | |
| Dimension of the encoder layers and the pooler layer. | |
| num_hidden_layers (`int`, *optional*, defaults to 28): | |
| Number of hidden layers in the Transformer encoder. | |
| num_attention_heads (`int`, *optional*, defaults to 32): | |
| Number of attention heads for each attention layer in the Transformer encoder. | |
| inner_hidden_size (`int`, *optional*, defaults to 16384): | |
| Dimension of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder. | |
| max_sequence_length (`int`, *optional*, defaults to 512): | |
| The maximum sequence length that this model might ever be used with. | |
| Typically set this to something large just in case (e.g., 512 or 1024 or 2048). | |
| layernorm_epsilon (`float`, *optional*, defaults to 1e-5): | |
| The epsilon used by the layer normalization layers. | |
| use_cache (`bool`, *optional*, defaults to `True`): | |
| Whether the model should return the last key/values attentions (not used by all models). | |
| Example: | |
| ```python | |
| >>> from configuration_chatglm import ChatGLMConfig | |
| >>> from modeling_chatglm import ChatGLMModel | |
| >>> # Initializing a ChatGLM-6B THUDM/ChatGLM-6B style configuration | |
| >>> configuration = ChatGLMConfig() | |
| >>> # Initializing a model from the THUDM/ChatGLM-6B style configuration | |
| >>> model = ChatGLMModel(configuration) | |
| >>> # Accessing the model configuration | |
| >>> configuration = model.config | |
| ``` | |
