tf.contrib.framework.nest.flatten_with_tuple_paths

Returns a list of (tuple_path, leaf_element) tuples.

tf.contrib.framework.nest.flatten_with_tuple_paths(
    structure, expand_composites=False
)

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 nest.yield_flat_paths for more information about tuple paths.

Args
structure	the nested structure to flatten.
expand_composites	If true, then composite tensors such as tf.SparseTensor and tf.RaggedTensor are expanded into their component tensors.

Returns
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 leaf_element within structure.
