+    This model inherits from [`TFPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a [tf.keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it
+    as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and
+    behavior.
+
+    <Tip>
+
+    TF 2.0 models accepts two formats as inputs:
+
+    - having all inputs as keyword arguments (like PyTorch models), or
+    - having all inputs as a list, tuple or dict in the first positional arguments.
+
+    This second option is useful when using [`tf.keras.Model.fit`] method which currently requires having all the
+    tensors in the first argument of the model call function: `model(inputs)`.
+
+    </Tip>
+
+    Parameters:
+        config ([`LayoutLMv3Config`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~TFPreTrainedModel.from_pretrained`] method to load the model weights.

+
+            - 1 indicates the head is **not masked**,
+            - 0 indicates the head is **masked**.
