r"""
|
| 25 |
+
This is the configuration class to store the configuration of a [`NewModel`] or a [`TFNewModel`]. It is used to
|
| 26 |
+
instantiate a NEW model according to the specified arguments, defining the model architecture. Instantiating a
|
| 27 |
+
configuration with the defaults will yield a similar configuration to that of the NEW
|
| 28 |
+
[izhx/new-base-en](https://huggingface.co/izhx/new-base-en) architecture.
|
| 29 |
+
|
| 30 |
+
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
|
| 31 |
+
documentation from [`PretrainedConfig`] for more information.
|
| 32 |
+
|
| 33 |
+
|
| 34 |
+
Args:
|
| 35 |
+
vocab_size (`int`, *optional*, defaults to 30522):
|
| 36 |
+
Vocabulary size of the NEW model. Defines the number of different tokens that can be represented by the
|
| 37 |
+
`inputs_ids` passed when calling [`NewModel`] or [`TFNewModel`].
|
| 38 |
+
hidden_size (`int`, *optional*, defaults to 768):
|
| 39 |
+
Dimensionality of the encoder layers and the pooler layer.
|
| 40 |
+
num_hidden_layers (`int`, *optional*, defaults to 12):
|
| 41 |
+
Number of hidden layers in the Transformer encoder.
|
| 42 |
+
num_attention_heads (`int`, *optional*, defaults to 12):
|
| 43 |
+
Number of attention heads for each attention layer in the Transformer encoder.
|
| 44 |
+
intermediate_size (`int`, *optional*, defaults to 3072):
|
| 45 |
+
Dimensionality of the "intermediate" (often named feed-forward) layer in the Transformer encoder.
|
| 46 |
+
hidden_act (`str` or `Callable`, *optional*, defaults to `"gelu"`):
|
| 47 |
+
The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
|
| 48 |
+
`"relu"`, `"silu"` and `"gelu_new"` are supported.
|
| 49 |
+
hidden_dropout_prob (`float`, *optional*, defaults to 0.1):
|
| 50 |
+
The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
|
| 51 |
+
attention_probs_dropout_prob (`float`, *optional*, defaults to 0.1):
|
| 52 |
+
The dropout ratio for the attention probabilities.
|
| 53 |
+
max_position_embeddings (`int`, *optional*, defaults to 512):
|
| 54 |
+
The maximum sequence length that this model might ever be used with. Typically set this to something large
|
| 55 |
+
just in case (e.g., 512 or 1024 or 2048).
|
| 56 |
+
type_vocab_size (`int`, *optional*, defaults to 2):
|
| 57 |
+
The vocabulary size of the `token_type_ids` passed when calling [`NewModel`] or [`TFNewModel`].
|
| 58 |
+
initializer_range (`float`, *optional*, defaults to 0.02):
|
| 59 |
+
The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
|
| 60 |
+
layer_norm_eps (`float`, *optional*, defaults to 1e-12):
|
| 61 |
+
The epsilon used by the layer normalization layers.
|
| 62 |
+
position_embedding_type (`str`, *optional*, defaults to `"rope"`):
|
| 63 |
+
Type of position embedding. Choose one of `"absolute"`, `"rope"`.
|
| 64 |
+
rope_theta (`float`, *optional*, defaults to 10000.0):
|
| 65 |
+
The base period of the RoPE embeddings.
|
| 66 |
+
rope_scaling (`Dict`, *optional*):
|
| 67 |
+
Dictionary containing the scaling configuration for the RoPE embeddings. Currently supports two scaling
|
| 68 |
+
strategies: linear and dynamic. Their scaling factor must be a float greater than 1. The expected format is
|
| 69 |
+
`{"type": strategy name, "factor": scaling factor}`. When using this flag, don't update
|
| 70 |
+
`max_position_embeddings` to the expected new maximum. See the following thread for more information on how
|
| 71 |
+
these scaling strategies behave:
|
| 72 |
+
https://www.reddit.com/r/LocalLLaMA/comments/14mrgpr/dynamically_scaled_rope_further_increases/. This is an
|
| 73 |
+
experimental feature, subject to breaking API changes in future versions.
|
| 74 |
+
classifier_dropout (`float`, *optional*):
|
| 75 |
+
The dropout ratio for the classification head.
|
| 76 |
+
|
| 77 |
+
Examples:
|
| 78 |
+
|

|

r"""
|
| 25 |
+
This is the configuration class to store the configuration of a [`NewModel`] or a [`TFNewModel`]. It is used to
|
| 26 |
+
instantiate a NEW model according to the specified arguments, defining the model architecture. Instantiating a
|
| 27 |
+
configuration with the defaults will yield a similar configuration to that of the NEW
|
| 28 |
+
[izhx/new-base-en](https://huggingface.co/izhx/new-base-en) architecture.
|
| 29 |
+
|
| 30 |
+
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
|
| 31 |
+
documentation from [`PretrainedConfig`] for more information.
|
| 32 |
+
|
| 33 |
+
|
| 34 |
+
Args:
|
| 35 |
+
vocab_size (`int`, *optional*, defaults to 30522):
|
| 36 |
+
Vocabulary size of the NEW model. Defines the number of different tokens that can be represented by the
|
| 37 |
+
`inputs_ids` passed when calling [`NewModel`] or [`TFNewModel`].
|
| 38 |
+
hidden_size (`int`, *optional*, defaults to 768):
|
| 39 |
+
Dimensionality of the encoder layers and the pooler layer.
|
| 40 |
+
num_hidden_layers (`int`, *optional*, defaults to 12):
|
| 41 |
+
Number of hidden layers in the Transformer encoder.
|
| 42 |
+
num_attention_heads (`int`, *optional*, defaults to 12):
|
| 43 |
+
Number of attention heads for each attention layer in the Transformer encoder.
|
| 44 |
+
intermediate_size (`int`, *optional*, defaults to 3072):
|
| 45 |
+
Dimensionality of the "intermediate" (often named feed-forward) layer in the Transformer encoder.
|
| 46 |
+
hidden_act (`str` or `Callable`, *optional*, defaults to `"gelu"`):
|
| 47 |
+
The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
|
| 48 |
+
`"relu"`, `"silu"` and `"gelu_new"` are supported.
|
| 49 |
+
hidden_dropout_prob (`float`, *optional*, defaults to 0.1):
|
| 50 |
+
The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
|
| 51 |
+
attention_probs_dropout_prob (`float`, *optional*, defaults to 0.1):
|
| 52 |
+
The dropout ratio for the attention probabilities.
|
| 53 |
+
max_position_embeddings (`int`, *optional*, defaults to 512):
|
| 54 |
+
The maximum sequence length that this model might ever be used with. Typically set this to something large
|
| 55 |
+
just in case (e.g., 512 or 1024 or 2048).
|
| 56 |
+
type_vocab_size (`int`, *optional*, defaults to 2):
|
| 57 |
+
The vocabulary size of the `token_type_ids` passed when calling [`NewModel`] or [`TFNewModel`].
|
| 58 |
+
initializer_range (`float`, *optional*, defaults to 0.02):
|
| 59 |
+
The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
|
| 60 |
+
layer_norm_eps (`float`, *optional*, defaults to 1e-12):
|
| 61 |
+
The epsilon used by the layer normalization layers.
|
| 62 |
+
position_embedding_type (`str`, *optional*, defaults to `"rope"`):
|
| 63 |
+
Type of position embedding. Choose one of `"absolute"`, `"rope"`.
|
| 64 |
+
rope_theta (`float`, *optional*, defaults to 10000.0):
|
| 65 |
+
The base period of the RoPE embeddings.
|
| 66 |
+
rope_scaling (`Dict`, *optional*):
|
| 67 |
+
Dictionary containing the scaling configuration for the RoPE embeddings. Currently supports two scaling
|
| 68 |
+
strategies: linear and dynamic. Their scaling factor must be a float greater than 1. The expected format is
|
| 69 |
+
`{"type": strategy name, "factor": scaling factor}`. When using this flag, don't update
|
| 70 |
+
`max_position_embeddings` to the expected new maximum. See the following thread for more information on how
|
| 71 |
+
these scaling strategies behave:
|
| 72 |
+
https://www.reddit.com/r/LocalLLaMA/comments/14mrgpr/dynamically_scaled_rope_further_increases/. This is an
|
| 73 |
+
experimental feature, subject to breaking API changes in future versions.
|
| 74 |
+
classifier_dropout (`float`, *optional*):
|
| 75 |
+
The dropout ratio for the classification head.
|
| 76 |
+
|
| 77 |
+
Examples:
|
| 78 |
+
|
