class YoutuConfig(PreTrainedConfig):
|
|
r"""
|
|
This is the configuration class to store the configuration of a [`YoutuModel`]. It is used to instantiate an Youtu
|
|
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 Youtu-LLM-2B.
|
|
e.g. [tencent/Youtu-LLM-2B](https://huggingface.co/tencent/Youtu-LLM-2B)
|
|
|
|
Configuration objects inherit from [`PreTrainedConfig`] and can be used to control the model outputs. Read the
|
|
documentation from [`PreTrainedConfig`] for more information.
|
|
|
|

`inputs_ids` passed when calling [`YoutuModel`]

|
|
Dimension of the value heads.
|
|
qk_nope_head_dim (`int`, *optional*, defaults to 128):

|
|
The dropout ratio for the attention probabilities.
