Specifies the rank, dtype and shape of every input to a layer.
tf.keras.layers.InputSpec( dtype=None, shape=None, ndim=None, max_ndim=None, min_ndim=None, axes=None )
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.
A None entry in a shape is compatible with any dimension, a None shape is compatible with any shape.
Arguments | |
---|---|
dtype | Expected DataType of the input. |
shape | Shape tuple, expected shape of the input (may include None for unchecked axes). |
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. |
