+
class AquilaConfig(PretrainedConfig):
|
| 27 |
+
r"""
|
| 28 |
+
This is the configuration class to store the configuration of a [`AquilaModel`]. It is used to instantiate an Aquila
|
| 29 |
+
model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
|
| 30 |
+
defaults will yield a similar configuration to that of the Aquila-7B.
|
| 31 |
+
|
| 32 |
+
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
|
| 33 |
+
documentation from [`PretrainedConfig`] for more information.
|
| 34 |
+
|
| 35 |
+
|
| 36 |
+
Args:
|
| 37 |
+
vocab_size (`int`, *optional*, defaults to 32000):
|
| 38 |
+
Vocabulary size of the Aquila model. Defines the number of different tokens that can be represented by the
|
| 39 |
+
`inputs_ids` passed when calling [`AquilaModel`]
|
| 40 |
+
hidden_size (`int`, *optional*, defaults to 4096):
|
| 41 |
+
Dimension of the hidden representations.
|
| 42 |
+
intermediate_size (`int`, *optional*, defaults to 11008):
|
| 43 |
+
Dimension of the MLP representations.
|
| 44 |
+
num_hidden_layers (`int`, *optional*, defaults to 32):
|
| 45 |
+
Number of hidden layers in the Transformer encoder.
|
| 46 |
+
num_attention_heads (`int`, *optional*, defaults to 32):
|
| 47 |
+
Number of attention heads for each attention layer in the Transformer encoder.
|
| 48 |
+
hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
|
| 49 |
+
The non-linear activation function (function or string) in the decoder.
|
| 50 |
+
max_position_embeddings (`int`, *optional*, defaults to 2048):
|
| 51 |
+
The maximum sequence length that this model might ever be used with. Typically set this to something large
|
| 52 |
+
just in case (e.g., 512 or 1024 or 2048).
|
| 53 |
+
initializer_range (`float`, *optional*, defaults to 0.02):
|
| 54 |
+
The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
|
| 55 |
+
rms_norm_eps (`float`, *optional*, defaults to 1e-12):
|
| 56 |
+
The epsilon used by the rms normalization layers.
|
| 57 |
+
use_cache (`bool`, *optional*, defaults to `True`):
|
| 58 |
+
Whether or not the model should return the last key/values attentions (not used by all models). Only
|
| 59 |
+
relevant if `config.is_decoder=True`.
|
| 60 |
+
tie_word_embeddings(`bool`, *optional*, defaults to `False`):
|
| 61 |
+
Whether to tie weight embeddings
|
| 62 |
+
Example:
|
| 63 |
+
|
| 64 |
+
```python
|
| 65 |
+
>>> from transformers import AquilaModel, AquilaConfig
|
| 66 |
+
|
| 67 |
+
>>> # Initializing a Aquila aquila-7b style configuration
|
| 68 |
+
>>> configuration = AquilaConfig()
|
| 69 |
+
|
| 70 |
+
>>> # Initializing a model from the aquila-7b style configuration
|
| 71 |
+
>>> model = AquilaModel(configuration)
