tf.keras.tree.assert_same_structure

Asserts that two structures are nested in the same way.

tf.keras.tree.assert_same_structure( a, b, check_types=True )

Note that namedtuples with identical name and fields will not be considered as same structures even check_types=False.

Examples:

keras.tree.assert_same_structure([(0, 1)], [(2, 3)])
 
Foo = collections.namedtuple('Foo', ['a', 'b']) AlsoFoo = collections.namedtuple('Foo', ['a', 'b']) keras.tree.assert_same_structure(Foo(0, 1), Foo(2, 3)) keras.tree.assert_same_structure(Foo(0, 1), AlsoFoo(2, 3)) Traceback (most recent call last):  ValueError: `a` and `b` don't have the same structure.

a an arbitrarily nested structure.
b an arbitrarily nested structure.
check_types if True (default) types of leaves are checked as well.
