tf.contrib.framework.nest.flatten_dict_items

Returns a dictionary with flattened keys and values.

tf.contrib.framework.nest.flatten_dict_items(
    dictionary
)

This function flattens the keys and values of a dictionary, which can be arbitrarily nested structures, and returns the flattened version of such structures:

example_dictionary = {(4, 5, (6, 8)): ("a", "b", ("c", "d"))}
result = {4: "a", 5: "b", 6: "c", 8: "d"}
flatten_dict_items(example_dictionary) == result

The input dictionary must satisfy two properties:

1. Its keys and values should have the same exact nested structure.
2. The set of all flattened keys of the dictionary must not contain repeated keys.

Args
dictionary	the dictionary to zip

Returns
The zipped dictionary.

Raises
TypeError	If the input is not a dictionary.
ValueError	If any key and value do not have the same structure layout, or if keys are not unique.
