class InternLMConfig(PretrainedConfig):
|
31 |
-
r"""
|
32 |
-
This is the configuration class to store the configuration of a [`InternLMModel`]. It is used to instantiate
|
33 |
-
an InternLM model according to the specified arguments, defining the model architecture. Instantiating a
|
34 |
-
configuration with the defaults will yield a similar configuration to that of the InternLM-7B.
|
35 |
-
|
36 |
-
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
|
37 |
-
documentation from [`PretrainedConfig`] for more information.
|
38 |
-
|
39 |
-
|
40 |
-
Args:
|
41 |
-
vocab_size (`int`, *optional*, defaults to 32000):
|
42 |
-
Vocabulary size of the InternLM model. Defines the number of different tokens that can be represented by the
|
43 |
-
`inputs_ids` passed when calling [`InternLMModel`]
|
44 |
-
hidden_size (`int`, *optional*, defaults to 4096):
|
45 |
-
Dimension of the hidden representations.
|
46 |
-
intermediate_size (`int`, *optional*, defaults to 11008):
|
47 |
-
Dimension of the MLP representations.
|
48 |
-
num_hidden_layers (`int`, *optional*, defaults to 32):
|
49 |
-
Number of hidden layers in the Transformer encoder.
|
50 |
-
num_attention_heads (`int`, *optional*, defaults to 32):
|
51 |
-
Number of attention heads for each attention layer in the Transformer encoder.
|
52 |
-
num_key_value_heads (`int`, *optional*):
|
53 |
-
This is the number of key_value heads that should be used to implement Grouped Query Attention. If
|
54 |
-
`num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
|
55 |
-
`num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
|
56 |
-
converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
|
57 |
-
by meanpooling all the original heads within that group. For more details checkout [this
|
58 |
-
paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to
|
59 |
-
`num_attention_heads`.
|
60 |
-
hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
|
61 |
-
The non-linear activation function (function or string) in the decoder.
|
62 |
-
max_position_embeddings (`int`, *optional*, defaults to 2048):
|
63 |
-
The maximum sequence length that this model might ever be used with. Typically set this to something large
|
64 |
-
just in case (e.g., 512 or 1024 or 2048).
|
65 |
-
initializer_range (`float`, *optional*, defaults to 0.02):
|
66 |
-
The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
|
67 |
-
rms_norm_eps (`float`, *optional*, defaults to 1e-12):
|
68 |
-
The epsilon used by the rms normalization layers.
|
69 |
-
use_cache (`bool`, *optional*, defaults to `True`):
|
70 |
-
Whether or not the model should return the last key/values attentions (not used by all models). Only
|
71 |
-
relevant if `config.is_decoder=True`.
|
72 |
-
tie_word_embeddings(`bool`, *optional*, defaults to `False`):
|
73 |
-
Whether to tie weight embeddings
|
74 |
-
Example:
|
75 |
-
|
76 |
-
```python
|
77 |
-
>>> from transformers import InternLMModel, InternLMConfig
|
78 |
-
|
79 |
-
>>> # Initializing a InternLM internlm-7b style configuration
|
80 |
-
>>> configuration = InternLMConfig()
