It is used to instantiate a ViTMatte 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 ViTMatte [hustvl/vitmatte-small-composition-1k](https://huggingface.co/hustvl/vitmatte-small-composition-1k) architecture. Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the documentation from [`PretrainedConfig`] for more information. Args: backbone_config (`PretrainedConfig` or `dict`, *optional*, defaults to `VitDetConfig()`): The configuration of the backbone model. backbone (`str`, *optional*): Name of backbone to use when `backbone_config` is `None`. If `use_pretrained_backbone` is `True`, this will load the corresponding pretrained weights from the timm or transformers library. If `use_pretrained_backbone` is `False`, this loads the backbone's config and uses that to initialize the backbone with random weights. use_pretrained_backbone (`bool`, *optional*, defaults to `False`): Whether to use pretrained weights for the backbone. use_timm_backbone (`bool`, *optional*, defaults to `False`): Whether to load `backbone` from the timm library. If `False`, the backbone is loaded from the transformers library. backbone_kwargs (`dict`, *optional*): Keyword arguments to be passed to AutoBackbone when loading from a checkpoint e.g. `{'out_indices': (0, 1, 2, 3)}`. Cannot be specified if `backbone_config` is set. hidden_size (`int`, *optional*, defaults to 384): The number of input channels of the decoder. batch_norm_eps (`float`, *optional*, defaults to 1e-05): The epsilon used by the batch norm layers. initializer_range (`float`, *optional*, defaults to 0.02): The standard deviation of the truncated_normal_initializer for initializing all weight matrices. convstream_hidden_sizes (`List[int]`, *optional*, defaults to `[48, 96, 192]`): The output channels of the ConvStream module. fusion_hidden_sizes (`List[int]`, *optional*, defaults to `[256, 128, 64, 32]`): The output channels of the Fusion blocks. Example: ```python >>> from transformers import VitMatteConfig, VitMatteForImageMatting >>> # Initializing a ViTMatte hustvl/vitmatte-small-composition-1k style configuration >>> configuration = VitMatteConfig() >>> # Initializing a model (with random weights) from the hustvl/vitmatte-small-composition-1k style configuration >>> model = VitMatteForImageMatting(configuration) >>> # Accessing the model configuration >>> configuration = model.config ```vitmatteNFigh㈵>g{Gz?)0`)@ backbone_config hidden_sizebatch_norm_epsinitializer_rangeconvstream_hidden_sizesfusion_hidden_sizesc  tjdi| |4|2tdt ddg}nLt |t r7|d} t| } | |}t|||||||_ ||_ ||_ ||_ ||_||_||_||_| |_| |_dS)NzX`backbone_config` is `None`.
