Symbolic tensor -- encapsulates a shape and a dtype.
tf.keras.KerasTensor(
shape,
dtype='float32',
sparse=False,
ragged=False,
record_history=True,
name=None,
**kwargs
)
You can use KerasTensor instances to build computation
graphs of Keras operations, such as keras.Function
objects or Functional keras.models.Model objects.
Example:
x = keras.KerasTensor(shape=(3, 4), dtype="float32")x.shape(3, 4)x.dtypefloat32
Calling a Keras operation (including a layer or a model)
on a KerasTensor instance will return another KerasTensor
instance with the appropriate shape and dtype. This is
called a "symbolic call" (since there is no actual data
involved). The computation of the correct output shape and
dtype is called "static shape inference".
