class Rwkv5Config(PretrainedConfig):
"""
This is the configuration class to store the configuration of a [`Rwkv5Model`]. It is used to instantiate a RWKV5
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-5-world-1b5](https://huggingface.co/RWKV/rwkv-5-world-1b5) 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 65536):
Vocabulary size of the RWKV5 model. Defines the number of different tokens that can be represented by the
`inputs_ids` passed when calling [`Rwkv5Model`].
hidden_size (`int`, *optional*, defaults to 768):
Dimensionality of the embeddings and hidden states.
num_hidden_layers (`int`, *optional*, defaults to 24):
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.
num_attention_heads (`int`, *optional*, defaults to 64):
The attention heads to use in rwkv5 self_attention module.
head_size (`int`, *optional*, defaults to 64): head_size of rwkv5 self_attention module.
intermediate_size (`int`, *optional*):
Dimensionality of the inner feed-forward layers. Will default to 4 times `hidden_size` if unset.
layer_norm_epsilon (`float`, *optional*, defaults to 1e-05):
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.
eos_token_id (`int`, *optional*, defaults to 0):
The id of the end of sentence token in the vocabulary. Defaults to 0.
rescale_every (`int`, *optional*, defaults 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 Rwkv5Config, Rwkv5Model
>>> # Initializing a Rwkv5 configuration
>>> configuration = Rwkv5Config()
>>> # Initializing a model (with random weights) from the configuration
>>> model = Rwkv5Model(configuration)
>>> # Accessing the model configuration
>>> configuration = model.config

This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
etc.) This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module)
subclass. Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to
general usage and behavior.
Parameters:
config ([`Rwkv5Config`]): Model configuration class with all the parameters of the model.
Initializing with a config file does not load the weights associated with the model, only the
configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

sequence tokens in the vocabulary. If `past_key_values` is used, only `input_ids` that do not have their
past calculated should be passed as `input_ids`. Indices can be obtained using [`AutoTokenizer`]. See
[`PreTrainedTokenizer.encode`] and [`PreTrainedTokenizer.__call__`] for details. [What are input
IDs?](../glossary#input-ids)
inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
model's internal embedding lookup matrix.
state (tuple of five `torch.FloatTensor` of shape `(batch_size, hidden_size, num_hidden_layers)`, *optional*):
If passed along, the model uses the previous state in all the blocks (which will give the output for the
`input_ids` provided as if the model add `state_input_ids + input_ids` as context).
use_cache (`bool`, *optional*):
If set to `True`, the last state is returned and can be used to quickly generate the next logits.
output_attentions (`bool`, *optional*):
Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
tensors for more detail.
output_hidden_states (`bool`, *optional*):
Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
