Project Description

iminuit

Interactive IPython-Friendly Minimizer based on SEAL Minuit2. (A slightly modified version is included in the package no need to install it separately)

It is designed from ground up to be fast, interactive and cython friendly. iminuit extracts function signature very permissively starting from checking func_code down to last resort of parsing docstring(or you could tell iminuit to stop looking and take your answer). The interface is inspired heavily by PyMinuit and the status printout is inspired by ROOT Minuit. iminuit is mostly compatible with PyMinuit(with few exceptions). Existing PyMinuit code can be ported to iminuit by just changing the import statement.

In a nutshell:

from iminuit import Minuit
def f(x, y, z):
    return (x - 2) ** 2 + (y - 3) ** 2 + (z - 4) ** 2
m = Minuit(f)
m.migrad()
print(m.values)  # {'x': 2,'y': 3,'z': 4}
print(m.errors)  # {'x': 1,'y': 1,'z': 1}

Install

First install cython (pip install cython), then

python setup.py install

or from pip:

pip install iminuit

For Windows, Christoph Gohlke made a nice windows binary to save you all from Windows compilation nightmare:
