Returns the shape of tensor or variable as a tuple of int or None entries.
Aliases:
tf.keras.backend.int_shape(x)
Arguments:
x: Tensor or variable.
Returns:
A tuple of integers (or None entries).
Examples:
>>> from keras import backend as K
>>> input = K.placeholder(shape=(2, 4, 5))
>>> K.int_shape(input)
(2, 4, 5)
>>> val = np.array([[1, 2], [3, 4]])
>>> kvar = K.variable(value=val)
>>> K.int_shape(kvar)
(2, 2)
