class Llama3Config(PretrainedConfig):
r"""
This is the configuration class to store the configuration of a [`MllamaForConditionalGeneration`]. It is used to instantiate an
Mllama 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 Mllama-9B.
e.g. [meta-llama/Llama-3.2-11B-Vision](https://huggingface.co/meta-llama/Llama-3.2-11B-Vision)
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
documentation from [`PretrainedConfig`] for more information.
Args:
vision_config (`Union[AutoConfig, dict]`, *optional*, defaults to `MllamaVisionConfig`):
The config object or dictionary of the vision backbone.
text_config (`Union[AutoConfig, dict]`, *optional*, defaults to `MllamaTextConfig`):
The config object or dictionary of the text backbone.
image_token_index (`int`, *optional*, defaults to 128256):
The image token index to encode the image prompt.
Example:
```python
>>> from transformers import MllamaForConditionalGeneration, MllamaConfig, MllamaVisionConfig, MllamaTextConfig
>>> # Initializing a CLIP-vision config
>>> vision_config = MllamaVisionConfig()
>>> # Initializing a Llama config
>>> text_config = MllamaTextConfig()
>>> # Initializing a mllama-11b style configuration
>>> configuration = MllamaConfig(vision_config, text_config)
>>> # Initializing a model from the mllama-11b style configuration
>>> model = MllamaForConditionalGeneration(configuration)
>>> # Accessing the model configuration
>>> configuration = model.config
