tf.contrib.framework.nest.flatten_dict_items

Returns a dictionary with flattened keys and values.

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.
