class RwkvConfig(PretrainedConfig):
"""
This is the configuration class to store the configuration of a [`RwkvModel`]. It is used to instantiate a RWKV
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 RWVK-4
[RWKV/rwkv-4-169m-pile](https://huggingface.co/RWKV/rwkv-4-169m-pile) 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 50277):
Vocabulary size of the RWKV model. Defines the number of different tokens that can be represented by the
`inputs_ids` passed when calling [`RwkvModel`].
context_length (`int`, *optional*, defaults to 1024):
The maximum sequence length that this model can be be used with in a single forward (using it in RNN mode
lets use any sequence length).
hidden_size (`int`, *optional*, defaults to 4096):
Dimensionality of the embeddings and hidden states.
num_hidden_layers (`int`, *optional*, defaults to 32):
Number of hidden layers in the model.
attention_hidden_size (`int`, *optional*):
Dimensionality of the attention hidden states. Will default to `hidden_size` if unset.
intermediate_size (`int`, *optional*):
Dimensionality of the inner feed-forward layers. Will default to 4 times `hidden_size` if unset.
layer_norm_eps (`float`, *optional*, defaults to 1e-5):
The epsilon to use in the layer normalization layers.
bos_token_id (`int`, *optional*, defaults to 0):
The id of the beginning of sentence token in the vocabulary. Defaults to 0 as RWKV uses the same tokenizer
as GPTNeoX.
eos_token_id (`int`, *optional*, defaults to 0):
The id of the end of sentence token in the vocabulary. Defaults to 0 as RWKV uses the same tokenizer as
GPTNeoX.
rescale_every (`int`, *optional*, default to 6):
At inference, the hidden states (and weights of the correponding output layers) are divided by 2 every
`rescale_every` layer. If set to 0 or a negative number, no rescale is done.
tie_word_embeddings (`bool`, *optional*, defaults to `False`):
Whether or not to tie the word embeddings with the input token embeddings.
use_cache (`bool`, *optional*, defaults to `True`):
Whether or not the model should return the last state.
Example:
```python
>>> from transformers import RwkvConfig, RwkvModel
>>> # Initializing a Rwkv configuration
>>> configuration = RwkvConfig()
>>> # Initializing a model (with random weights) from the configuration
>>> model = RwkvModel(configuration)
>>> # Accessing the model configuration
>>> configuration = model.config
