class LlamaConfig(LlamaConfig):
    r"""
   This is the configuration class to store the configuration of a [`LlamaModel`]. It is used to instantiate an LLaMA
   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 LLaMA-7B.

   Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
   documentation from [`PretrainedConfig`] for more information.


    Args:
        naive_attention_prefill (`bool`, *optional*, defaults to False):
            Whether to use naive matmul or scaled dot product attention during prefill.
        naive_attention_decode_batched (`bool`, *optional*, defaults to True):
            Whether to use naive matmul or scaled dot product attention during decode for batch_size > 1.
        naive_attention_decode_single (`bool`, *optional*, defaults to False):
            Whether to use naive matmul or scaled dot product attention during decode for batch_size == 1.
