+class MobileViTV2Config(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`MobileViTV2Model`]. It is used to instantiate a
+    MobileViTV2 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 MobileViTV2
+    [apple/mobilevitv2-1.0](https://huggingface.co/apple/mobilevitv2-1.0) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        num_channels (`int`, *optional*, defaults to 3):
+            The number of input channels.
+        image_size (`int`, *optional*, defaults to 256):
+            The size (resolution) of each image.
+        patch_size (`int`, *optional*, defaults to 2):
+            The size (resolution) of each patch.
+        expand_ratio (`float`, *optional*, defaults to 2.0):
+            Expansion factor for the MobileNetv2 layers.
+        hidden_act (`str` or `function`, *optional*, defaults to `"swish"`):
+            The non-linear activation function (function or string) in the Transformer encoder and convolution layers.
+        conv_kernel_size (`int`, *optional*, defaults to 3):
+            The size of the convolutional kernel in the MobileViTV2 layer.
+        output_stride (`int`, *optional*, defaults to 32):
+            The ratio of the spatial resolution of the output to the resolution of the input image.
+        classifier_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout ratio for attached classifiers.
+        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-05):
+            The epsilon used by the layer normalization layers.
+        aspp_out_channels (`int`, *optional*, defaults to 512):
+            Number of output channels used in the ASPP layer for semantic segmentation.
+        atrous_rates (`List[int]`, *optional*, defaults to `[6, 12, 18]`):
+            Dilation (atrous) factors used in the ASPP layer for semantic segmentation.
+        aspp_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout ratio for the ASPP layer for semantic segmentation.
+        semantic_loss_ignore_index (`int`, *optional*, defaults to 255):
+            The index that is ignored by the loss function of the semantic segmentation model.
+        n_attn_blocks (`List[int]`, *optional*, defaults to `[2, 4, 3]`):
+            The number of attention blocks in each MobileViTV2Layer
+        base_attn_unit_dims (`List[int]`, *optional*, defaults to `[128, 192, 256]`):
+            The base multiplier for dimensions of attention blocks in each MobileViTV2Layer
+        width_multiplier (`float`, *optional*, defaults to 1.0):
+            The width multiplier for MobileViTV2.
+        ffn_multiplier (`int`, *optional*, defaults to 2):
+            The FFN multiplier for MobileViTV2.
+        attn_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout in the attention layer.
+        ffn_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout between FFN layers.
+
+    Example:
+
+    ```python
+    >>> from transformers import MobileViTV2Config, MobileViTV2Model
+
+    >>> # Initializing a mobilevitv2-small style configuration
+    >>> configuration = MobileViTV2Config()
+
+    >>> # Initializing a model from the mobilevitv2-small style configuration
+    >>> model = MobileViTV2Model(configuration)
+
+    >>> # Accessing the model configuration
+    >>> configuration = model.config
