Tree
tree is a library for working with nested data structures. In a way, tree
generalizes the builtin map function which only supports flat sequences,
and allows to apply a function to each "leaf" preserving the overall
structure.
>>> import tree
>>> structure = [[1], [[[2, 3]]], [4]]
>>> tree.flatten(structure)
[1, 2, 3, 4]
>>> tree.map_structure(lambda v: v**2, structure)
[[1], [[[4, 9]]], [16]]
tree is backed by an optimized C++ implementation suitable for use in
demanding applications, such as machine learning models.
