tf.keras.backend.ndim(
    x
)

Arguments:

x: Tensor or variable.

Returns:

Integer (scalar), number of axes.

Examples:

>>> input = tf.keras.backend.placeholder(shape=(2, 4, 5))
>>> val = np.array([[1, 2], [3, 4]])
>>> kvar = tf.keras.backend.variable(value=val)
>>> tf.keras.backend.ndim(input)
3
>>> tf.keras.backend.ndim(kvar)
2
