from transformers.configuration_utils import PretrainedConfig
class GlmConfig(PretrainedConfig):
r"""
This is the configuration class to store the configuration of a [`GlmModel`]. It is used to instantiate an Glm
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 Glm-4-9b-chat.
e.g. [THUDM/glm-4-9b-chat](https://huggingface.co/THUDM/glm-4-9b-chat)
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 151552):
Vocabulary size of the Glm model. Defines the number of different tokens that can be represented by the
`inputs_ids` passed when calling [`GlmModel`]
hidden_size (`int`, *optional*, defaults to 4096):
Dimension of the hidden representations.
intermediate_size (`int`, *optional*, defaults to 13696):
Dimension of the MLP representations.
num_hidden_layers (`int`, *optional*, defaults to 40):
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*, defaults to 2):
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`.
head_dim (`int`, *optional*, defaults to 128):
The attention head dimension.
hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
The legacy activation function. It is overwritten by the `hidden_activation`.
attention_dropout (`float`, *optional*, defaults to 0.0):
The dropout ratio for the attention probabilities.
max_position_embeddings (`int`, *optional*, defaults to 131072):
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 1.5625e-07):
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`.
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.
pad_token_id (`int`, *optional*, defaults to 151329):
Padding token id.
eos_token_id (`int` | `list`, *optional*, defaults to `[151329, 151336, 151338]`):
End of stream token id.
bos_token_id (`int`, *optional*):
Beginning of stream token id.
attention_bias (`bool`, defaults to `False`, *optional*, defaults to `True`):
Whether to use a bias in the query, key, value and output projection layers during self-attention.
boi_token_id (`int`, *optional*, defaults to 151339):
Beginning of image token id.
eoi_token_id (`int` | `list`, *optional*, defaults to `[151339, 151346, 151348]`):
End of image token id.
partial_rotary_factor (`float`, *optional*, defaults to 0.5):
The partial rotary factor.
vision_config (`VisionConfig`, *optional*, defaults to `None`):
The vision configuration object.
