  --- BEGIN ISSUE ---
  Simplify docstring example of `TokenAndPositionEmbedding`
  The current [docstring example](https://github.com/keras-team/keras-nlp/blob/3a951a9f5442b77a0c474bb8b61406f65c7ef924/keras_nlp/layers/token_and_position_embedding.py#L45) of `TokenAndPositionEmbedding` is a bit more complicated than needed and should better match newer examples like those in [`keras_nlp.models.BertBackbone`](https://github.com/keras-team/keras-nlp/blob/3a951a9f5442b77a0c474bb8b61406f65c7ef924/keras_nlp/models/bert/bert_backbone.py#L67).
  
  Make the following changes to the docstring example:
  * Create a real input of the correct shape using `tf.ones`
  * Inline constant values like `"seq_length"` directly into the function calls
  
  Be sure to check that your example runs on colab or your local machine!

  15 """Creates an Embedding Layer and adds Positional Embeddings"""

  25     """A layer which sums a token and position embedding.
  26 
  27     Token and position embeddings are ways of representing words and their order
  28     in a sentence. This layer creates a `keras.layers.Embedding` token embedding
  29     and a `keras_nlp.layers.PositionEmbedding` position embedding and sums their
  30     output when called. This layer assumes that the last dimension in the input
  31     corresponds to the sequence dimension.
  32 
  33     Args:
  34         vocabulary_size: The size of the vocabulary.
  35         sequence_length: The maximum length of input sequence
  36         embedding_dim: The output dimension of the embedding layer
  37         embeddings_initializer: The initializer to use for the Embedding
  38             Layers
  39         mask_zero: Boolean, whether or not the input value 0 is a special
  40             "padding" value that should be masked out.
  41             This is useful when using recurrent layers which may take variable
  42             length input. If this is True, then all subsequent layers in the
  43             model need to support masking or an exception will be raised.
  44             If mask_zero` is set to True, as a consequence, index 0 cannot be
  45             used in the vocabulary
  46             (input_dim should equal size of vocabulary + 1).
  47 
  48     Examples:
  49     ```python
  50     seq_length = 50
  51     vocab_size = 5000

This layer creates a `keras.layers.Embedding` token embedding\n    and a `keras_nlp.layers.PositionEmbedding` position embedding and sums their\n    output when called. This layer assumes that the last dimension in the input\n    corresponds to the sequence dimension.\n\n    Args:\n        vocabulary_size: The size of the vocabulary.\n        sequence_length: The maximum length of input sequence\n        embedding_dim: The output dimension of the embedding layer\n        embeddings_initializer: The initializer to use for the Embedding\n            Layers\n        mask_zero: Boolean, whether or not the input value 0 is a special\n            \"padding\" value that should be masked out.\n            This is useful when using recurrent layers which may take variable\n            length input. If this is True, then all subsequent layers in the\n            model need to support masking or an exception will be raised.\n            If mask_zero` is set to True, as a consequence, index 0 cannot be\n            used in the vocabulary\n            (input_dim should equal size of vocabulary + 1).\n\n    Examples:\n    ```python\n    inputs = tf.ones(shape=(1, 50), dtype=tf.int64)\n    embedding_layer = keras_nlp.layers.TokenAndPositionEmbedding(\n        vocabulary_size=10_000,\n        sequence_length=50,\n        embedding_dim=128,\n    )\n    outputs = embedding_layer(inputs)\n    ```\n    \"\"\"\n\n    def __init__(\n        self,\n        vocabulary_size,\n        sequence_length,\n        embedding_dim,\n        embeddings_initializer=\"glorot_uniform\",\n        mask_zero=False,\n        **kwargs\n    ):\n        super().__init__(**kwargs)\n        if vocabulary_size is None:\n            raise ValueError(\n                \"`vocabulary_size` must be an Integer, received `None`.\"\n            )\n        if sequence_length is None:\n            raise ValueError(\n                \"`sequence_length` must be an Integer, received `None`.\"\n            )\n        if embedding_dim is None:\n            raise ValueError(\n                \"`embedding_dim` must be an Integer, received `None`.\"\n            )\n        self.vocabulary_size = int(vocabulary_size)\n        self.sequence_length = int(sequence_length)\n        self.embedding_dim = int(embedding_dim)\n        self.embeddings_initializer = keras.initializers.get(\n            embeddings_initializer\n        )\n        self.token_embedding = keras.layers.Embedding(\n            vocabulary_size,\n            embedding_dim,\n            embeddings_initializer=clone_initializer(\n                self.embeddings_initializer\n            ),\n            mask_zero=mask_zero,\n            name=\"token_embedding\"\n            + str(keras.backend.get_uid(\"token_embedding\")),\n        )\n        self.position_embedding = keras_nlp.layers.PositionEmbedding(\n            sequence_length=sequence_length,\n            initializer=clone_initializer(self.embeddings_initializer),\n            name=\"position_embedding\"\n            + str(keras.backend.get_uid(\"position_embedding\")),\n        )\n        self.supports_masking = self.token_embedding.supports_masking\n\n    def get_config(self):\n        config = super().get_config()\n        config.update(\n            {\n                \"vocabulary_size\": self.vocabulary_size,\n                \"sequence_length\": self.sequence_length,\n                \"embedding_dim\": self.embedding_dim,\n                \"embeddings_initializer\": keras.initializers.serialize(\n                    self.embeddings_initializer\n                ),\n                \"mask_zero\": self.token_embedding.mask_zero,\n            },\n        )\n        return config\n\n    def call(self, inputs):\n        embedded_tokens = self.token_embedding(inputs)\n        embedded_positions = self.position_embedding(embedded_tokens)\n        outputs = embedded_tokens + embedded_positions\n        return outputs\n\n    def compute_mask(self, inputs, mask=None):\n        return self.token_embedding.compute_mask(inputs, mask=mask)\n", "path": "keras_nlp/layers/token_and_position_embedding.py"}]}
