""" TVLT model configuration"""
from ...configuration_utils import PretrainedConfig

logger = logging.get_logger(__name__)
class TvltConfig(PretrainedConfig):
r"""
This is the configuration class to store the configuration of a [`TvltModel`]. It is used to instantiate a TVLT
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 TVLT
[ZinengTang/tvlt-base](https://huggingface.co/ZinengTang/tvlt-base) architecture.
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
documentation from [`PretrainedConfig`] for more information.
Args:
image_size (`int`, *optional*, defaults to 224):
The size (resolution) of each image.
spectrogram_length (`int`, *optional*, defaults to 2048):
The time length of each audio spectrogram.
frequency_length (`int`, *optional*, defaults to 128):
The frequency length of audio spectrogram.
image_patch_size (`List[int]`, *optional*, defaults to `[16, 16]`):
The size (resolution) of each image patch.
audio_patch_size (`List[int]`, *optional*, defaults to `[16, 16]`):
The size (resolution) of each audio patch.
num_image_channels (`int`, *optional*, defaults to 3):
The number of input image channels.
num_audio_channels (`int`, *optional*, defaults to 1):
The number of input audio channels.
num_frames (`int`, *optional*, defaults to 8):
The maximum number of frames for an input video.
hidden_size (`int`, *optional*, defaults to 768):
Dimensionality of the encoder layers and the pooler layer.
num_hidden_layers (`int`, *optional*, defaults to 12):
Number of hidden layers in the Transformer encoder.
num_attention_heads (`int`, *optional*, defaults to 12):
Number of attention heads for each attention layer in the Transformer encoder.
intermediate_size (`int`, *optional*, defaults to 3072):
Dimensionality of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
`"relu"`, `"selu"` and `"gelu_new"` are supported.
hidden_dropout_prob (`float`, *optional*, defaults to 0.0):
The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
attention_probs_dropout_prob (`float`, *optional*, defaults to 0.0):
The dropout ratio for the attention probabilities.
initializer_range (`float`, *optional*, defaults to 0.02):
The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
layer_norm_eps (`float`, *optional*, defaults to 1e-06):
The epsilon used by the layer normalization layers.
qkv_bias (`bool`, *optional*, defaults to `True`):
Whether to add a bias to the queries, keys and values.
use_mean_pooling (`bool`, *optional*, defaults to `False`):
Whether to mean pool the final hidden states instead of using the final hidden state of the [CLS] token.
decoder_num_attention_heads (`int`, *optional*, defaults to 16):
Number of attention heads for each attention layer in the decoder.
decoder_hidden_size (`int`, *optional*, defaults to 512):
Dimensionality of the decoder.
decoder_num_hidden_layers (`int`, *optional*, defaults to 8):
Number of hidden layers in the decoder.
decoder_intermediate_size (`int`, *optional*, defaults to 2048):
Dimensionality of the "intermediate" (i.e., feed-forward) layer in the decoder.
pixel_mask_ratio (`float`, *optional*, defaults to 0.75):
Image patch masking ratio.
audio_mask_ratio (`float`, *optional*, defaults to 0.15):
Audio patch masking ratio.
audio_mask_type (`str`, *optional*, defaults to `"frame-level"`):
Audio patch masking type, choose between "frame-level" and "patch-level".
task_matching (`bool`, *optional*, defaults to `True`):
Whether to use vision audio matching task in pretraining.
task_mae (`bool`, *optional*, defaults to `True`):
Whether to use the masked auto-encoder (MAE) in pretraining.
loss_type (`str`, *optional*, defaults to `"classification"`):
Loss types including regression and classification.
Example:
```python
>>> from transformers import TvltConfig, TvltModel
>>> # # Initializing a TVLT ZinengTang/tvlt-base style configuration
>>> configuration = TvltConfig()
>>> # # Initializing a model (with random weights) from the ZinengTang/tvlt-base style configuration
>>> model = TvltModel(configuration)
>>> # Accessing the model configuration
>>> configuration = model.config
