Russell Bryant e489ad7a21 [Misc] Add SPDX-License-Identifier headers to python source files (#12628)
- **Add SPDX license headers to python source files**
- **Check for SPDX headers using pre-commit**

    Add SPDX license headers to python source files
    
This commit adds SPDX license headers to python source files as
recommended to
the project by the Linux Foundation. These headers provide a concise way
that is
both human and machine readable for communicating license information
for each
source file. It helps avoid any ambiguity about the license of the code
and can
    also be easily used by tools to help manage license compliance.
    
The Linux Foundation runs license scans against the codebase to help
ensure
    we are in compliance with the licenses of the code we use, including
dependencies. Having these headers in place helps that tool do its job.

r"""
This is the configuration class to store the configuration of a
[`UltravoxForConditionalGeneration`]. It is used to instantiate an
Ultravox model according to the specified arguments, defining the model
architecture.
Configuration objects inherit from [`PretrainedConfig`] and can be used to
control the model outputs. Read the documentation from [`PretrainedConfig`]
for more information.
Args:
audio_config (`Union[AutoConfig, dict]`, *optional*):
Custom audio config or dict
text_config (`Union[AutoConfig, dict]`, *optional*):
The config object of the text backbone. Can be any of `LlamaConfig`
or `MistralConfig`.
ignore_index (`int`, *optional*, defaults to -100):
The ignore index for the loss function.
audio_token_index (`int`, *optional*, defaults to 32000):
The audio token index to encode the audio prompt.
stack_factor (`int`, *optional*, defaults to 8):
Audio downsampling factor for the multimodal projector.
norm_init (`float`, *optional*, defaults to 0.4):
The initialization value for the layer normalization.
projector_act (`str`, *optional*, defaults to `"swiglu"`):
The activation function used by the multimodal projector.
text_model_lora_config (`LoraConfigSimplified`, *optional*):
The LoRA configuration for finetuning the text model.
audio_model_lora_config (`LoraConfigSimplified`, *optional*):
The LoRA configuration for finetuning the audio model.
