Layers can expose (if appropriate) an `input_spec` attribute: an instance of `InputSpec`, or a nested structure of `InputSpec` instances (one per input tensor). These objects enable the layer to run input compatibility checks for input structure, input rank, input shape, and input dtype for the first argument of `Layer.__call__`. A `None` entry in a shape is compatible with any dimension. Args: dtype: Expected dtype of the input. shape: Shape tuple, expected shape of the input (may include `None` for dynamic axes). Includes the batch size. ndim: Integer, expected rank of the input. max_ndim: Integer, maximum rank of the input. min_ndim: Integer, minimum rank of the input. axes: Dictionary mapping integer axes to a specific dimension value. allow_last_axis_squeeze: If `True`, allow inputs of rank N+1 as long as the last axis of the input is 1, as well as inputs of rank N-1 as long as the last axis of the spec is 1. name: Expected key corresponding to this input when passing data as a dictionary. optional: Boolean, whether the input is optional or not. An optional input can accept `None` values. Example: ```python class MyLayer(Layer): def __init__(self): super().__init__() # The layer will accept inputs with # shape (*, 28, 28) & (*, 28, 28, 1) # and raise an appropriate error message otherwise. self.input_spec = InputSpec( shape=(None, 28, 28, 1), allow_last_axis_squeeze=True) ``` Nc |tj|nd|_|+tj||_t ||_n||_d|_||_||_||_ | |_ ||_ |xsi}|D cic]} t| || c} |_ |jrv|j |j]|j r |j n |jdz } t!|j} | | kDrtdj#| | yyycc} w#ttf$rtd|wxYw)NzAArgument `axes` must be a dict with integer keys.

This checks that the tensor(s) `inputs` verify the input assumptions of a layer (if any). If not, a clear and actional exception gets raised. Args: input_spec: An InputSpec instance, list of InputSpec instances, a nested structure of InputSpec instances, or None. inputs: Input tensor, list of input tensors, or a nested structure of input tensors. layer_name: String, name of the layer (for error message formatting). Raises: ValueError: in case of mismatch between the provided inputs and the expectations of the layer. NzMissing data for input "z*". You passed a data dictionary with keys z.
