It is used to instantiate an ViLT27 model according to the specified arguments, defining the model architecture. Instantiating a configuration with the28 defaults will yield a similar configuration to that of the ViLT29 [dandelin/vilt-b32-mlm](https://huggingface.co/dandelin/vilt-b32-mlm) architecture.30 31 Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the32 documentation from [`PretrainedConfig`] for more information.33 34 Args:35 vocab_size (`int`, *optional*, defaults to 30522):36 Vocabulary size of the text part of the model. Defines the number of different tokens that can be37 represented by the `inputs_ids` passed when calling [`ViltModel`].38 type_vocab_size (`int`, *optional*, defaults to 2):39 The vocabulary size of the `token_type_ids` passed when calling [`ViltModel`]. This is used when encoding40 text.41 modality_type_vocab_size (`int`, *optional*, defaults to 2):42 The vocabulary size of the modalities passed when calling [`ViltModel`]. This is used after concatenating the43 embeddings of the text and image modalities.44 max_position_embeddings (`int`, *optional*, defaults to 40):45 The maximum sequence length that this model might ever be used with.46 hidden_size (`int`, *optional*, defaults to 768):47 Dimensionality of the encoder layers and the pooler layer.48 num_hidden_layers (`int`, *optional*, defaults to 12):49 Number of hidden layers in the Transformer encoder.50 num_attention_heads (`int`, *optional*, defaults to 12):51 Number of attention heads for each attention layer in the Transformer encoder.52 intermediate_size (`int`, *optional*, defaults to 3072):53 Dimensionality of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.54 hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):55 The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,56 `"relu"`, `"selu"` and `"gelu_new"` are supported.57 hidden_dropout_prob (`float`, *optional*, defaults to 0.0):58 The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.59 attention_probs_dropout_prob (`float`, *optional*, defaults to 0.0):60 The dropout ratio for the attention probabilities.61 initializer_range (`float`, *optional*, defaults to 0.02):62 The standard deviation of the truncated_normal_initializer for initializing all weight matrices.63 layer_norm_eps (`float`, *optional*, defaults to 1e-12):64 The epsilon used by the layer normalization layers.65 image_size (`int`, *optional*, defaults to 384):66 The size (resolution) of each image.67 patch_size (`int`, *optional*, defaults to 32):68 The size (resolution) of each patch.69 num_channels (`int`, *optional*, defaults to 3):70 The number of input channels.71 qkv_bias (`bool`, *optional*, defaults to `True`):72 Whether to add a bias to the queries, keys and values.73 max_image_length (`int`, *optional*, defaults to -1):74 The maximum number of patches to take as input for the Transformer encoder. If set to a positive integer,75 the encoder will sample `max_image_length` patches at maximum. If set to -1, will not be taken into76 account.77 num_images (`int`, *optional*, defaults to -1):78 The number of images to use for natural language visual reasoning. If set to a positive integer, will be79 used by [`ViltForImagesAndTextClassification`] for defining the classifier head.80 81 Example:82 83 ```python84 >>> from transformers import ViLTModel, ViLTConfig85 86 >>> # Initializing a ViLT dandelin/vilt-b32-mlm style configuration87 >>> configuration = ViLTConfig()88 89 >>> # Initializing a model from the dandelin/vilt-b32-mlm style configuration90 >>> model = ViLTModel(configuration)91 92 >>> # Accessing the model configuration93 >>> configuration = model.config94 ```"""95 96 model_type = "vilt"97 98 def __init__(99 self,100 vocab_size=30522,101 type_vocab_size=2,102 modality_type_vocab_size=2,103 max_position_embeddings=40,104 hidden_size=768,105 num_hidden_layers=12,106 num_attention_heads=12,107 intermediate_size=3072,108 hidden_act="gelu",109 hidden_dropout_prob=0.0,110 attention_probs_dropout_prob=0.0,111 initializer_range=0.02,112 layer_norm_eps=1e-12,113 image_size=384,114 patch_size=32,115 num_channels=3,116 qkv_bias=True,117 max_image_length=-1,118 tie_word_embeddings=False,119 num_images=-1,120 **kwargs,121 ):122 super().__init__(tie_word_embeddings=tie_word_embeddings, **kwargs)123 124 self.vocab_size = vocab_size125 self.type_vocab_size = type_vocab_size126 self.modality_type_vocab_size = modality_type_vocab_size127 self.max_position_embeddings = max_position_embeddings128 129 self.hidden_size = hidden_size130 self.num_hidden_layers = num_hidden_layers131 self.num_attention_heads = num_attention_heads132 self.intermediate_size = intermediate_size133 self.hidden_act = hidden_act134 self.hidden_dropout_prob = hidden_dropout_prob135 self.attention_probs_dropout_prob = attention_probs_dropout_prob136 self.initializer_range = initializer_range137 self.layer_norm_eps = layer_norm_eps138 139 self.image_size = image_size140 self.patch_size = patch_size141 self.num_channels = num_channels142 self.qkv_bias = qkv_bias143 self.max_image_length = max_image_length144 self.num_images = num_images145 146 147__all__ = ["ViltConfig"]148
