autodiffpy - Group 13

autodiffpy is a library implementing automatic differentiation to make the calculation of gradients of complex functions fast and precise.

Installation

pip install autodiffpy-free-holmes

Getting Started with Forward mode

from autodiffpy.forward import Forward

x = Forward('x', 3)
f = x ** 2

print(f.value, f.get_gradient('x'))
>>> 9 6

Getting Started with Reverse mode

from autodiffpy.reverse import Reverse

x = Reverse(3)
f = x ** 2

f.gradient_value = 1

print(f.value, x.get_gradient())
>>> 9 6
