Introduction

NNI (Neural Network Intelligence) is a toolkit to help users running automated machine learning experiments. The tool dispatches and runs trial jobs that generated by tuning algorithms to search the best neural architecture and/or hyper-parameters at different environments (e.g. local, remote servers and cloud).

Who should consider using NNI

You want to try different AutoML algorithms for your training code (model) at local
You want to run AutoML trial jobs in different environments to speed up search (e.g. remote servers and cloud)
As a researcher and data scientist, you want to implement your own AutoML algorithms and compare with other algorithms
As a ML platform owner, you want to support AutoML in your platform

Getting Started with NNI

Installation

Install through python pip

requirements: python >= 3.5

pip3 install -v --user git+https://github.com/Microsoft/nni.git@v0.1
source ~/.bashrc

Quick start: run an experiment at local

Requirements:

NNI installed on your local machine

Run the following command to create an experiment for [mnist]

    nnictl create --config ~/nni/examples/trials/mnist-annotation/config.yml

This command will start an experiment and a WebUI. The WebUI endpoint will be shown in the output of this command (for example, http://localhost:8080). Open this URL in your browser. You can analyze your experiment through WebUI, or browse trials' tensorboard.
