class CpmBeeConfig(PretrainedConfig):
r"""
This is the configuration class to store the configuration of a [`CpmBeeModel`]. It is used to instbeeiate an
CPMBee 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 CPMBee
[openbmb/cpm-bee-10b](https://huggingface.co/openbmb/cpm-bee-10b) architecture.
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 30720):
Vocabulary size of the CPMBee model. Defines the number of different tokens that can be represented by the
`input` passed when calling [`CpmBeeModel`].
hidden_size (`int`, *optional*, defaults to 4096):
Dimension of the encoder layers.
num_attention_heads (`int`, *optional*, defaults to 32):
Number of attention heads in the Transformer encoder.
dim_head (`int`, *optional*, defaults to 128):
Dimension of attention heads for each attention layer in the Transformer encoder.
dim_ff (`int`, *optional*, defaults to 10240):
Dimension of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
num_hidden_layers (`int`, *optional*, defaults to 48):
Number of layers of the Transformer encoder.
dropout_p (`float`, *optional*, defaults to 0.1):
The dropout probabilitiy for all fully connected layers in the embeddings, encoder.
position_bias_num_buckets (`int`, *optional*, defaults to 512):
The number of position_bias buckets.
position_bias_num_segment_buckets (`int`, *optional*, defaults to 32):
The number of segment buckets.
position_bias_max_distance (`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).
eps (`float`, *optional*, defaults to 1e-6):
The epsilon used by the layer normalization layers.
init_std (`float`, *optional*, defaults to 1.0):
Initialize parameters with std = init_std.
use_cache (`bool`, *optional*, defaults to `True`):
Whether to use cache.
distance_scale (`float` or `int`, *optional*, defaults to 16):
Scale the rotary embedding.
mask_modules (`list` or `tuple`, *optional*, defaults to None):
Decides which feedforward block or attention block is pruned.
half (`bool`, *optional*, defaults to `False`):
Decides the model parameters are half-precision or not.
Example:
```python
>>> from transformers import CpmBeeModel, CpmBeeConfig
>>> # Initializing a CPMBee cpm-bee-10b style configuration
>>> configuration = CpmBeeConfig()
>>> # Initializing a model from the cpm-bee-10b style configuration
>>> model = CpmBeeModel(configuration)
>>> # Accessing the model configuration
>>> configuration = model.config
