iminuit is a Jupyter-friendly Python interface for the Minuit2 C++ library maintained by CERN's ROOT team.
It can be used as a general robust function minimisation method, but is most commonly used for likelihood fits of models to data, and to get model parameter error estimates from likelihood profile analysis.
from iminuit import Minuit def fcn(x, y, z): return (x - 2) ** 2 + (y - 3) ** 2 + (z - 4) ** 2 fcn.errordef = Minuit.LEAST_SQUARES m = Minuit(fcn, x=0, y=0, z=0) m.migrad() ## run optimiser print(m.values) ## x: 2, y: 3, z: 4 m.hesse() ## run covariance estimator print(m.errors) ## x: 1, y: 1, z: 1
The current 2.x series has introduced breaking interfaces changes with respect to the 1.x series.
All interface changes are documented in the changelog with recommendations how to upgrade. To keep existing scripts running, pin your major iminuit version to <2, i.e.
pip install 'iminuit<2' installs the 1.x series.
Rodrigo Senra - Jupyter Notebooks - Olá pessoal e sejam bem-vindos à mais um episódio do Castálio Podcast! Nosso convidado de hoje é diretor técnico na Work & Co, PhD em Ciências da Computação, já contribuiu com inúmeros projetos open source em Python, ajudou a fundar a Associação Python Brasil e já foi premiado com o Prêmio …
The Jupyter Notebook is also an incredibly powerful tool for interactively developing and presenting data science projects. This tutorial will walk you through how to set up Jupyter Notebooks on your local machine and how to start using it to do data science projects. As a web application in which you can create and share documents that contain live code, equations, visualizations as well as text, the Jupyter Notebook is one of the ideal tools to help you to gain the data science skills you need.So, don't forget to join us at 7:00 PM IST for the Great Learning experience!
In this Python tutorial, we’re going to explore Jupyter Notebooks and discuss their benefits and how to get started. What is Jupyter Notebook? Why use Jupyter Notebook? Get started with Jupyter. Create a new notebook. Add content to your notebook. Share your notebook
Why switch to JupyterLab from jupyter-notebook? Jupyter Notebook is a web-based interactive computational environment for creating Jupyter notebook documents.
In this blog, I want to share how you can turn Jupyter Notebooks into pdf format in a few lines! Instead of sharing your Jupyter Notebooks, it would be neater if you could convert the notebooks and submit the pdf version
