class JapaneseStableLMAlphaConfig(PretrainedConfig):
r"""
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 65536):
Vocabulary size of the JapaneseStableLMAlphaModel. Defines the number of different tokens that
can be represented by the `inputs_ids` passed when calling [`JapaneseStableLMAlphaModel`].
hidden_size (`int`, *optional*, defaults to 4096):
Dimension of the decoder layers and the pooler 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.
intermediate_size (`int`, *optional*, defaults to 16384):
Dimension of the "intermediate" (i.e., feed-forward) layer in the Transformer decoder.
hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
The non-linear activation function (function or string).
rotary_pct (`float`, *optional*, defaults to 0.25):
Percentage of hidden dimensions to allocate to rotary embeddings.
rotary_emb_base (`int`, *optional*, defaults to 10000)
Base for computing rotary embeddings frequency.
rotary_scale_base (`int`, *optional*, defaults to 512)
Base `scale` for computing XPos rotary embeddings scale.
classifier_dropout (`float`, *optional*, defaults to 0.1):
Argument used when doing token classification, used in the model
[`StableLMForTokenClassification`]. The dropout ratio for the hidden layer.
max_position_embeddings (`int`, *optional*, defaults to 2048):
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).
initializer_range (`float`, *optional*, defaults to 1e-5):
The standard deviation of the truncated_normal_initializer for initializing
all weight matrices.
layer_norm_eps (`float`, *optional*, defaults to 1e-12):
The epsilon used by the layer 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`.
use_parallel_residual (`bool`, *optional*, defaults to `True`):
Whether to use a "parallel" formulation in each Transformer layer,
which can provide a slight training speedup at large scales.
Example:
```python
>>> from transformers import JapaneseStableLMAlphaConfig, JapaneseStableLMAlphaModel
>>> # Initializing a JapaneseStableLMAlpha style configuration
>>> configuration = JapaneseStableLMAlphaConfig()
>>> # Initializing a model (with random weights) from the style configuration
>>> model = JapaneseStableLMAlphaModel(configuration) # doctest: +SKIP
>>> # Accessing the model configuration
>>> configuration = model.config # doctest: +SKIP
