Returns the symbolic shape of a tensor or variable.

tf.keras.backend.shape(
    x
)

Arguments:

  • x: A tensor or variable.

Returns:

A symbolic shape (which is itself a tensor).

Examples:

val = np.array([[1, 2], [3, 4]]) 
kvar = tf.keras.backend.variable(value=val) 
tf.keras.backend.shape(kvar) 
<tf.Tensor: shape=(2,), dtype=int32, numpy=array([2, 2], dtype=int32)> 
input = tf.keras.backend.placeholder(shape=(2, 4, 5)) 
tf.keras.backend.shape(input) 
<tf.Tensor 'Shape_...' shape=(3,) dtype=int32>
