Autodifferentiation tool for Python.

Installation

Install the fork:

pip install chumpy

Import it:

import chumpy as ch

Overview

Chumpy is a Python-based framework designed to handle the auto-differentiation problem, which is to evaluate an expression and its derivatives with respect to its inputs, by use of the chain rule.

Chumpy is intended to make construction and local minimization of objectives easier.

Specifically, it provides:

  • Easy problem construction by using Numpy’s application interface
  • Easy access to derivatives via auto differentiation
  • Easy local optimization methods (12 of them: most of which use the derivatives)

Usage

Chumpy comes with its own demos, which can be seen by typing the following:

import chumpy
chumpy.demo() # prints out a list of possible demos
