tf.keras.tree.assert_same_structure

Asserts that two structures are nested in the same way.

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.
