Returns a list of
(tuple_path, leaf_element) tuples.
The order of pairs produced matches that of
nest.flatten. This allows you
to flatten a nested structure while keeping information about where in the
structure each data element was located. See
for more information about tuple paths.
the nested structure to flatten.
If true, then composite tensors such as tf.SparseTensor
and tf.RaggedTensor are expanded into their component tensors.
A list of
(tuple_path, leaf_element) tuples. Each
tuple_path is a tuple
of indices and/or dictionary keys that uniquely specify the path to
